  • Google Analytics on Android

    - by pjv
    There is a specific and official analytics SDK for native Android apps (note that I'm not talking about webpages in apps on a phone). This library basically sends pages and events to Google Analytics and you can view your analytics in exactly the same dashboard as for websites. Since my background is apps rather than websites, and since a lot of the Google Analytics terminology seems particularly inapplicable to a native app, I need some pointers. Please discuss my remarks, provide some clarification where you think I'm off-track, and above all share good experiences! 1. Page Views Pages mostly can match different Activities (and Dialogs) being displayed. Activities can be visible behind non-full-screen Activities however, though only the top-level Activity can be interacted. This sort-off clashes with a "(page) view". You'd also want at least one page view for each visit and therefore put one page view tracker in the Application class. However this does not constitute a window or sorts. Usually an Activity will open at the same time, so the time spent on that page will have been 0. This will influence your "time spent" statistics. How are these counted anyway? Moreover, there is a loose coupling between the Activities, by means of Intents. A user can, much like on any website, step in at any Activity, although usually this then concerns resuming the application where he left off. This makes that the hierarchy of Activities usually is very flat. And since there are no url's involved. What meaning would using slashes in page titles have, such as "/Home"? All pages would appear on an equal level in the reports, so no content drilldown. Non-unique page views seem to be counted as some kind of indicator of successfulness: how often does the visitor revisit the page. When the user rotates the screen however usually an Activity resumes again, thus making it a new page view. This happens a lot. Maybe a well-thought-through placement of the call might solve this, or placing several, I'm not sure. How to deal with Page Views? 2. Events I'd say there are two sorts: A user event Something that happened, usually as an indirect consequence of the above. The latter particularly is giving me headaches. First of all, many events aren't written in code any more, but pieced logically together by means of Intents. This means that there is no place to put the analytics call. You'd either have to give up this advantage and start doing it the old-fashioned way in favor of good analytics, or, just be missing some events. Secondly, as a developer you're not so much interested in when a user clicks a button, but if the action that should have been performed really was performed and what the result was. There seems to be no clear way to get resulting data into Google Analytics (what's up with the integers? I want to put in Strings!). The same that applies to the flat pages hierarchy, also goes for the event categories. You could do "vertical" categories (topically, that is), but some code is shared "horizontally" and the tracking will be equally shared. Just as with the Intents mechanism, inheritance makes it hard for you to put the tracking in the right places at all times. And I can't really imagine "horizontal" categories. Unless you start making really small categories, such as all the items form the same menu in one category, I have a hard time grasping the concept. Finally, how do you deal with cancelling? Usually you both have an explicit cancel mechanism by ways of a button, as well as the implicit cancel when the "back"-button is pressed to leave the activity and there were no changes. The latter also applies to "saves", when the back button is pressed and there ARE changes. How are you consequently going to catch all these if not by doing all the "back"-button work yourself? How to deal with events? 3. Goals For goal types I have choice of: URL Destination, Time on Site, and Pages/Visit. Most apps don't have a funnel that leads the user to some "registration done" or "order placed" page. Apps have either already been bought (in which case you want to stimulate the user to love your app, so that he might bring on new buyers) or are paid for by in-app ads. So URL Destination is not a very important goal. Time on Site also seems troublesome. First, I have some doubt on how this would be measured. Second, I don't necessarily want my user to spend a lot of time in my already paid app, just be active and content. Equivalently, why not mention how frequent a user uses your app? Regarding Pages/Visit I already mentioned how screen orientation changes blow up the page view numbers. In an app I'd be most interested in events/visit to measure the user's involvement/activity. If he's intensively using the app then he must be loving it right? Furthermore, I also have some small funnels (that do not lead to conversion though) that I want to see streamlined. In my mind those funnels would end in events rather than page views but that seems not to be possible. I could also measure clickthroughs on in-app ads, but then I'd need to track those as Page Views rather than Events, in view of "URL Destination". What are smart goals for apps and how can you fit them on top of Analytics? 4. Optimisation Is there a smart way to manually do what "Website Optimiser" does for websites? Most importantly, how would I track different landing page designs? 5. Traffic Sources Referrals deal with installation time referrals, if you're smart enough to get them included. But perhaps I'd also want to get some data which third-party app sends users to my app to perform some actions (this app interoperability is possible via Intents). Many of the terminologies related to "Traffic Sources" seem totally meaningless and there is no possibility of connecting in AdSense. What are smart uses of this data? 6. Visitors Of the "Browser capabilities", "Network Properties" and "Mobile" tabs, many things are pointless as they have no influence on / relation with my mostly offline app that won't use flash anyway. Only if you drill down far enough, can you get to OS versions, which do matter a lot. I even forgot where you could check what exact Android devices visited. What are smart uses of this data? How can you make the relevant info more prominent? 7. Other No in-page analytics. I have to register my app as a web-url (What!?)?

  • Marmalade SDK views navigation concepts

    - by Mina Samy
    I want to develop a simple multi-Activity Android game using Marmalade SDK. I looked at the SDK samples and found that most of them are a single view (Android Activity) apps. The Navigation model in Android is a stack-like model where views are pushed and popped. I can't find whether Marmalade has a similar model or it uses a different approach. would you please explain this to me and provide tutorials and samples to navigation in Marmalade if possible ? Thanks

  • How to manage feeds with subclassed object in Django 1.2?

    - by Matteo
    Hi, I'm trying to generate a feed rss from a model like this one, selecting all the Entry objects: from django.db import models from django.contrib.sites.models import Site from django.contrib.auth.models import User from imagekit.models import ImageModel import datetime class Entry(ImageModel): date_pub = models.DateTimeField(default=datetime.datetime.now) author = models.ForeignKey(User) via = models.URLField(blank=True) comments_allowed = models.BooleanField(default=True) icon = models.ImageField(upload_to='icon/',blank=True) class IKOptions: spec_module = 'journal.icon_specs' cache_dir = 'icon/resized' image_field = 'icon' class Post(Entry): title = models.CharField(max_length=200) description = models.TextField() slug = models.SlugField(unique=True) def __unicode__(self): return self.title class Photo(Entry): alt = models.CharField(max_length=200) description = models.TextField(blank=True) original = models.ImageField(upload_to='photo/') class IKOptions: spec_module = 'journal.photo_specs' cache_dir = 'photo/resized' image_field = 'original' def __unicode__(self): return self.alt class Quote(Entry): blockquote = models.TextField() cite = models.TextField(blank=True) def __unicode__(self): return self.blockquote When I use the render_to_response in my views I simply call: def get_journal_entries(request): entries = Entry.objects.all().order_by('-date_pub') return render_to_response('journal/entries.html', {'entries':entries}) And then I use a conditional template to render the right snippets of html: {% extends "base.html" %} {% block main %} <hr> {% for entry in entries %} {% if entry.post %}[...]{% endif %}[...] But I cannot do the same with the Feed Framework in django 1.2... Any suggestion, please?

Partition-level ADO and compression are supported if partitioned on the ORA_ARCHIVE_STATE column.

ADO does not perform checks for storage space in a target tablespace when using storage tiering. ADO is not supported on tables with object types or materialized views. ADO concurrency (the number of simultaneous policy jobs for ADO) depends on the concurrency of the Oracle scheduler. If a policy job for ADO fails more than two times, then the job is marked disabled and the job must be manually enabled later. Policies for ADO are only run in the Oracle Scheduler maintenance windows. Outside of the maintenance windows all policies are stopped.

  • Hard disk with bad clusters

    - by Dan
    I have been trying to backup some files up to DVD recently, and the burn process failed saying the CRC check failed for certain files. I then tried to browse to these files in Windows explorer and my whole machine locks up and I have to reboot. I ran check disk without the '/F /R' arguments and it told me I had bad sectors. So I re-ran it with the arguments and check disk fails during the 'Chkdsk is verifying usn journal' stage with this error: Insufficient disk space to fix the usn journal $j data stream The hard disk is a 300GB Partition on a 400GB Disk, and there is 160GBs of free space on the partition. My os (Windows 7) is installed on the other partition and is running fine. Any idea how I fix this? or repair it enough to copy my files off it?

  • Xen DomU on DRBD device: barrier errors

    I'm testing setting up a Xen DomU with a DRBD storage for easy failover. Most of the time, immediatly after booting the DomU, I get an IO error: [ 3.153370] EXT3-fs (xvda2): using internal journal [ 3.277115] ip_tables: (C) 2000-2006 Netfilter Core Team [ 3.336014] nf_conntrack version 0.5.0 (3899 buckets, 15596 max) [ 3.515604] init: failsafe main process (397) killed by TERM signal [ 3.801589] blkfront: barrier: write xvda2 op failed [ 3.801597] blkfront: xvda2: barrier or flush: disabled [ 3.801611] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801630] end_request: I/O error, dev xvda2, sector 52171168 [ 3.801642] Buffer I/O error on device xvda2, logical block 6521396 [ 3.801652] lost page write due to I/O error on xvda2 [ 3.801755] Aborting journal on device xvda2.

This can be seen in /proc/drbd (by "wo:f, meaning flush, the next method drbd chooses after barrier): 3: cs:Connected ro:Primary/Secondary ds:UpToDate/UpToDate C r---- ns:2160152 nr:520204 dw:2680344 dr:2678107 al:3549 bm:9183 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 And on the other host: 3: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r---- ns:0 nr:2160152 dw:2160152 dr:0 al:0 bm:8052 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0 I also enabled the option disable_sendpage, as per the drbd docs: cat /sys/module/drbd/parameters/disable_sendpage Y I also tried adding barriers=0 to fstab as mount option. Still it sometimes says: [ 58.603896] blkfront: barrier: write xvda2 op failed [ 58.603903] blkfront: xvda2: barrier or flush: disabled I don't even know if ext3 has a nobarrier option. And, because only one of my storage systems is battery backed, it would not be smart anyway. Why does it still compain about barriers when I disabled that?

  • win2008 r2 enterprise "Message Queuing" "Access is denied" "The list of messages cannot be retrieved"

    - by gerryLowry
    on my win7, I run compmgmt.msc and drill to a private queue folder ... when I click "Queue messages" or "Journal messages", I either see the messages, or "There are no items to show in this view". BUT, on win2008 R2 Enterprise, I run compmgmt.msc and drill to a private queue folder ... when I click "Queue messages" or "Journal messages", I see "There are no items to show in this view" which AFAIK is correct BUT I get this unwanted dialog: Message Queuing x ------------------------ (X) The list of messages cannot be retrieved. Error: Access is denied. [[ OK ]] On both computers, I'm a member of local Administrators. I'm concerned as a developer because I'm very soon going to be testing WCF/MSMQ software that works on my Win7 laptop. How to I get past this denied access problem? thnx / g.

  • The Debut of Oracle Database Firewall at RSA 2011

    - by Troy Kitch
    We're very proud of the coverage and headlines Oracle Database Firewall made this past week during RSA Conference 2011 in San Francisco. In case you missed our previous post, we announced the availability of this latest addition to the Oracle Defense-in-Depth database security solutions. The announcement was picked up many publications including eWeek, CRN, InformationWeek and more. Here is just some of the press on this very important security solution: "It's rare to find a new product category these days, but I think a new product from Oracle fills the bill. In the crowded enterprise security field, that's saying something." Enterprise System Journal: A New Approach to Database Security By James E. Powell "Databases and the content they store are among the most valuable IT assets - and the most targeted by hackers. In an effort to help secure databases, Oracle today is launching the new Oracle Database Firewall as an approach to defend databases against SQL injection and other database attacks." Database Journal: Oracle Debuts Database Firewall (also appeared in InternetNews.com) By Sean Michael Kerner "Oracle Database Firewall understands SQL-statement formats, and can be configured to blacklist and whitelist traffic based on source. When it detects suspicious statements within SQL traffic -- ones that might indicate SQL injection attacks, for example -- it can replace them with neutral statements that will keep the session running without allowing potentially harmful traffic through." Network World: Oracle Database Firewall defuses SQL injection attacks By Tim Green "The firewall uses "SQL grammar analysis" to prevent SQL injection attacks and other attempts to grab information. The Oracle Database Firewall features white and black lists policies, exceptions and rules that mark the time of day, IP address, application and user." ZDNet: RSA Roundup: Oracle Database Firewall By Larry Dignan "The database giant announced Oracle Database Firewall on Feb. 14 at the RSA Conference in San Francisco. The firewall application establishes a "defensive perimeter" around databases by monitoring and enforcing normal application behavior in real-time, the company said." eWEEK: Oracle Database Firewall Delivers Vendor-Agnostic Security By Fahmida Y.

  • Flash Technology Can Revolutionize your IT Infrastructure

    - by kimberly.billings
    A recent article in the Data Center Journal written by Mark Teter outlines how flash is becoming a disruptive technology in the data center and how it will soon replace HDDs in the storage hierarchy. As Teter explains, the drivers behind this trend are lower cost/performance and power savings; flash is over 100x faster for reads than the fastest HDD, and while it is expensive, it can produce dramatic reductions in the cost of performance as measured in Input/Outputs per second (IOPS). What's more, flash consumes 1/5th the power of HDD, so it's faster AND greener. Teter writes, "when appropriately used, flash turns the current economics of IT performance on its head. That's disruptive." Exadata Smart Flash Cache in the Sun Oracle Database Machine makes intelligent use of flash storage to deliver extreme performance for OLTP and mixed workloads. It intelligently caches data from the Oracle Database replacing slow mechanical I/O operations to disk with very rapid flash memory operations. Exadata Smart Flash Cache is the fundamental technology of the Sun Oracle Database Machine that enables the processing of up to 1 million random I/O operations per second (IOPS), and the scanning of data within Exadata storage at up to 50 GB/second. Are you incorporating flash into your storage strategy? Let us know! Read more: "Flash technology can revolutionize your IT infrastructure", The Data Center Journal, March 30, 2010.

  • Windows Workflow Foundation (WF) and things I wish were more intuitive

    - by pjohnson
    I've started using Windows Workflow Foundation, and so far ran into a few things that aren't incredibly obvious. Microsoft did a good job of providing a ton of samples, which is handy because you need them to get anywhere with WF. The docs are thin, so I've been bouncing between samples and downloadable labs to figure out how to implement various activities in a workflow. Code separation or not? You can create a workflow and activity in Visual Studio with or without code separation, i.e. just a .cs "Component" style object with a Designer.cs file, or a .xoml XML markup file with code behind (beside?) it. Absence any obvious advantage to one or the other, I used code separation for workflows and any complex custom activities, and without code separation for custom activities that just inherit from the Activity class and thus don't have anything special in the designer. So far, so good. Workflow Activity Library project type - What's the point of this separate project type? So far I don't see much advantage to keeping your custom activities in a separate project. I prefer to have as few projects as needed (and no fewer). The Designer's Toolbox window seems to find your custom activities just fine no matter where they are, and the debugging experience doesn't seem to be any different. Designer Properties - This is about the designer, and not specific to WF, but nevertheless something that's hindered me a lot more in WF than in Windows Forms or elsewhere. The Properties window does a good job of showing you property values when you hover the mouse over the values. But they don't do the same to find out what a control's type is. So maybe if I named all my activities "x1" and "x2" instead of helpful self-documenting names like "listenForStatusUpdate", then I could easily see enough of the type to determine what it is, but any names longer than those and all I get of the type is "System.Workflow.Act" or "System.Workflow.Compone". Even hitting the dropdown doesn't expand any wider, like the debugger quick watch "smart tag" popups do when you scroll through members. The only way I've found around this in VS 2008 is to widen the Properties dialog, losing precious designer real estate, then shrink it back down when you're done to see what you were doing. Really? WF Designer - This is about the designer, and I believe is specific to WF. I should be able to edit the XML in a .xoml file, or drag and drop using the designer. With WPF (at least in VS 2010 Ultimate), these are side by side, and changes to one instantly update the other. With WF, I have to right-click on the .xoml file, choose Open With, and pick XML Editor to edit the text. It looks like this is one way where WF didn't get the same attention WPF got during .NET Fx 3.0 development. Service - In the WF world, this is simply a class that talks to the workflow about things outside the workflow, not to be confused with how the term "service" is used in every other context I've seen in the Windows and .NET world, i.e. an executable that waits for events or requests from a client and services them (Windows service, web service, WCF service, etc.). ListenActivity - Such a great concept, yet so unintuitive. It seems you need at least two branches (EventDrivenActivity instances), one for your positive condition and one for a timeout. The positive condition has a HandleExternalEventActivity, and the timeout has a DelayActivity followed by however you want to handle the delay, e.g. a ThrowActivity. The timeout is simple enough; wiring up the HandleExternalEventActivity is where things get fun. You need to create a service (see above), and an interface for that service (this seems more complex than should be necessary--why not have activities just wire to a service directly?). And you need to create a custom EventArgs class that inherits from ExternalDataEventArgs--you can't create an ExternalDataEventArgs event handler directly, even if you don't need to add any more information to the event args, despite ExternalDataEventArgs not being marked as an abstract class, nor a compiler error nor warning nor any other indication that you're doing something wrong, until you run it and find that it always times out and get to check every place mentioned here to see why. Your interface and service need an event that consumes your custom EventArgs class, and a method to fire that event. You need to call that method from somewhere. Then you get to hope that you did everything just right, or that you can step through code in the debugger before your Delay timeout expires. Yes, it's as much fun as it sounds. TransactionScopeActivity - I had the bright idea of putting one in as a placeholder, then filling in the database updates later. That caused this error: The workflow hosting environment does not have a persistence service as required by an operation on the workflow instance "[GUID]". ...which is about as helpful as "Object reference not set to an instance of an object" and even more fun to debug. Google led me to this Microsoft Forums hit, and from there I figured out it didn't like that the activity had no children. Again, a Validator on TransactionScopeActivity would have pointed this out to me at design time, rather than handing me a nearly useless error at runtime. Easily enough, I disabled the activity and that fixed it. I still see huge potential in my work where WF could make things easier and more flexible, but there are some seriously rough edges at the moment. Maybe I'm just spoiled by how much easier and more intuitive development elsewhere in the .NET Framework is.

  • How do you keep from running into the same problems over and over?

    - by Stephen Furlani
    I keep running into the same problems. The problem is irrelevant, but the fact that I keep running into is completely frustrating. The problem only happens once every, 3-6 months or so as I stub out a new iteration of the project. I keep a journal every time, but I spend at least a day or two each iteration trying to get the issue resolved. How do you guys keep from making the same mistakes over and over? I've tried a journal but it apparently doesn't work for me. [Edit] A few more details about the issue: Each time I make a new project to hold the files, I import a particular library. The library is a C++ library which imports glew.h and glx.h GLX redefines BOOL and that's not kosher since BOOL is a keyword for ObjC. I had a fix the last time I went through this. I #ifndef the header in the library to exclude GLEW and GLX and everything worked hunky-dory. This time, however, I do the same thing, use the same #ifndef block but now it throws a bunch of errors. I go back to the old project, and it works. New project no-worky. It seems like it does this every time, and my solution to it is new each time for some reason. I know #defines and #includes are one of the trickiest areas of C++ (and cross-language with Objective-C), but I had this working and now it's not.

  • Would this data requirement suit a Document -Oriented database?

    - by codecowboy
    I have a requirement to allow users to fill in journal/diary entries per day. I want to provide a handful of known journal templates with x columns to fill in. An example might be a thought diary; a user has to record a thought in one column, describe the situation, rate how they felt etc. The other requirement is that a user should be able to create their own diary templates. They might have a need for a 10 column diary entry per day and might need to rate some aspect out of 50 instead of 10. In an RDBMS, I can see this getting quite complicated. I could have individual tables for my known templates as the fields will be fixed. But for custom diary templates I imagine I would would need a table storing custom_field_types (the diary columns), a table storing entries referencing their field types (custom_entries) and then a third custom_diary table which would store rows matching custom_entries to diaries. Leaving performance / scaling aside, would it be any simpler or make more sense to use a document oriented database like MongoDB to store this data? This is for a web application which might later need an API for mobile devices.

  • Need help with android.os.Build.VERSION.SDK_INT and SharedPreferences

    - by Fenderf4i
    I have a main activity where I call VersionSettings vs = new VersionSettings(this); if (vs.firstRun2()) vs.versionCheckbox(); What I'm trying to do is set a checkbox (checkboxVideoType) to an unchecked state if the Android version is 1.6-2.1 I only want to do this the very first time the app is ever run, it never needs to run again. I think I'm running into the problem when the main activity calls versionCheckbox(), I get a force close if it attempts to run the code inside that is going to set the checkbox to false. I'm very new to programming and would really appreciate some help with this. I think I'm close, but need a push. Thanks in advance!

Here are the parts of code Player.java package player.org; import android.app.Activity; import android.app.TabActivity; import android.content.Context; import android.content.Intent; import android.content.res.Resources; import android.media.MediaPlayer; import android.os.Bundle; import android.util.Log; import android.view.MotionEvent; import android.view.View; import android.view.View.OnClickListener; import android.view.animation.AlphaAnimation; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.Button; import android.widget.ProgressBar; import android.widget.SeekBar; import android.widget.SeekBar.OnSeekBarChangeListener; import android.widget.TabHost; import android.widget.TabWidget; import android.widget.TextView; public class Player extends TabActivity { /** Called when the activity is first created. */ private MediaPlayer media=null; private SeekBar progress; private View play; private Progress p; TabHost tabhost; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.tabs); Resources res=getResources(); //TabHost tabhost=(TabHost) findViewById(R.id.tabhost); // tabhost.setup(); tabhost=getTabHost(); TabHost.TabSpec spec; Intent intent; intent=new Intent(this,Progress.class); spec=tabhost.newTabSpec("now playing").setIndicator("Now playing", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); intent=new Intent(this,Group.class); spec=tabhost.newTabSpec("all_songs").setIndicator("All songs", res.getDrawable(R.drawable.songs)) .setContent(intent); tabhost.addTab(spec); //intent=new Intent(this,Progress.class); spec=tabhost.newTabSpec("artists").setIndicator("Artists", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); spec=tabhost.newTabSpec("alboom").setIndicator("Alboom", res.getDrawable(R.drawable.icon)) .setContent(intent); tabhost.addTab(spec); tabhost.setCurrentTab(0); } } Group.java import android.os.Bundle; import android.view.View; public class Group extends ActivityGroup { @Override public void onCreate(Bundle savedInstanceStated) { super.onCreate(savedInstanceStated); View view = getLocalActivityManager().startActivity("AllSongs", new Intent(this, AllSongs.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); setContentView(view); } AllSongs.java package player.org; import java.util.ArrayList; import android.R.id; import android.app.ActivityGroup; import android.app.ListActivity; import android.content.Intent; import android.os.Bundle; import android.view.View; import android.view.Window; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TabHost; public class AllSongs extends ListActivity{ ArrayList<String> listItem=new ArrayList<String>(); ArrayAdapter<String> adapter; ListView listView; //Player p; TabHost tab; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); //p=new Player(); adapter=new ArrayAdapter<String>(this,R.layout.list_item,listItem); setListAdapter(adapter); listView=getListView(); listView.setTextFilterEnabled(true); listView.setOnItemClickListener(listener); addItem("vahag"); addItem("vahagvahag"); } private OnItemClickListener listener=new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) { // TODO Auto-generated method stub Intent intent = new Intent(AllSongs.this,Progress.class); intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); Group group= (Group) getParent(); View view=group.getLocalActivityManager().startActivity("Progress",intent).getDecorView(); setContentView(view); } }; public void addItem(String s) { listItem.add(s); adapter.notifyDataSetChanged(); } } and the Progress.java package player.org; import android.app.Activity; import android.app.ActivityGroup; import android.app.Dialog; import android.app.TabActivity; import android.content.Context; public class Progress extends Activity { // Called when the activity is first created. public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); } } So, AllSongs.java try to change current activity with Progress activity, but when I press on list item, the Programm forsed closed, and logChat says "08-17 12:49:26.471: ERROR/AndroidRuntime(1500): java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list'" I can't figure how to fix this problem, Can anyone helps?

  • ListView not showing up in fragment

    - by aindurti
    When I insert a listview in a fragment in my application, it doesn't show up after I populate it with items. In fact, the application crashes due to a NullPointerException. Can anybody help me? Here is the detail activity from which I show the fragments. package com.example.sample; import android.content.Intent; import android.os.Bundle; import android.support.v4.app.Fragment; import android.support.v4.app.FragmentTransaction; import android.support.v4.app.NavUtils; import android.widget.ArrayAdapter; import android.widget.ListView; import com.actionbarsherlock.app.ActionBar; import com.actionbarsherlock.app.ActionBar.Tab; import com.actionbarsherlock.app.SherlockFragmentActivity; import com.actionbarsherlock.view.MenuItem; /** * An activity representing a single Course detail screen. This activity is only * used on handset devices. On tablet-size devices, item details are presented * side-by-side with a list of items in a {@link CourseListActivity}. * <p> * This activity is mostly just a 'shell' activity containing nothing more than * a {@link CourseDetailFragment}. */ public class CourseDetailActivity extends SherlockFragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_course_detail); // Show the Up button in the action bar. ActionBar actionBar = getSupportActionBar(); actionBar.setDisplayHomeAsUpEnabled(true); actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS); // initiating both tabs and set text to it. ActionBar.Tab assignTab = actionBar.newTab().setText("Assignments"); ActionBar.Tab schedTab = actionBar.newTab().setText("Schedule"); ActionBar.Tab contactTab = actionBar.newTab().setText("Contact"); // Create three fragments to display content Fragment assignFragment = new Assignments(); Fragment schedFragment = new Schedule(); Fragment contactFragment = new Contact(); assignTab.setTabListener(new MyTabsListener(assignFragment)); schedTab.setTabListener(new MyTabsListener(schedFragment)); contactTab.setTabListener(new MyTabsListener(contactFragment)); actionBar.addTab(assignTab); actionBar.addTab(schedTab); actionBar.addTab(contactTab); ListView listView = (ListView) findViewById(R.id.assignlist); String[] values = new String[] { "Android", "iPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2" }; // First paramenter - Context // Second parameter - Layout for the row // Third parameter - ID of the TextView to which the data is written // Forth - the Array of data ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); // Assign adapter to ListView listView.setAdapter(adapter); } @Override public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case android.R.id.home: // This ID represents the Home or Up button. In the case of this // activity, the Up button is shown. Use NavUtils to allow users // to navigate up one level in the application structure. For // more details, see the Navigation pattern on Android Design: // // http://developer.android.com/design/patterns/navigation.html#up-vs-back // NavUtils.navigateUpTo(this, new Intent(this, CourseListActivity.class)); return true; } return super.onOptionsItemSelected(item); } class MyTabsListener implements ActionBar.TabListener { public Fragment fragment; public Fragment fragment2; public MyTabsListener(Fragment fragment) { this.fragment = fragment; } @Override public void onTabReselected(Tab tab, FragmentTransaction ft) { } @Override public void onTabSelected(Tab tab, FragmentTransaction ft) { ft.replace(R.id.main_across, fragment); } @Override public void onTabUnselected(Tab tab, FragmentTransaction ft) { ft.remove(fragment); } } } The fragment that I am currently trying to get working is called the Assignments fragment. As you can see in the CourseDetailActvity, I populate smaple items in the listview to see if it the listview shows up. The fragment gets inflated properly, but when I try to add items to the listview, the application crashes! Here is the logcat. 11-17 11:54:28.037: E/AndroidRuntime(282): FATAL EXCEPTION: main 11-17 11:54:28.037: E/AndroidRuntime(282): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.sample/com.example.sample.CourseDetailActivity}: java.lang.NullPointerException 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2663) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2679) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread.access$2300(ActivityThread.java:125) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2033) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.os.Handler.dispatchMessage(Handler.java:99) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.os.Looper.loop(Looper.java:123) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread.main(ActivityThread.java:4627) 11-17 11:54:28.037: E/AndroidRuntime(282): at java.lang.reflect.Method.invokeNative(Native Method) 11-17 11:54:28.037: E/AndroidRuntime(282): at java.lang.reflect.Method.invoke(Method.java:521) 11-17 11:54:28.037: E/AndroidRuntime(282): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:868) 11-17 11:54:28.037: E/AndroidRuntime(282): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:626) 11-17 11:54:28.037: E/AndroidRuntime(282): at dalvik.system.NativeStart.main(Native Method) 11-17 11:54:28.037: E/AndroidRuntime(282): Caused by: java.lang.NullPointerException 11-17 11:54:28.037: E/AndroidRuntime(282): at com.example.sample.CourseDetailActivity.onCreate(CourseDetailActivity.java:66) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 11-17 11:54:28.037: E/AndroidRuntime(282): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2627) 11-17 11:54:28.037: E/AndroidRuntime(282): ... 11 more

  • Login box not shown on Ubuntu

    - by Alexandre
    Hi, I've installed Ubuntu 10.04 (64bit) as a guest OS in VirtualBox, using Windows7 Professional (64bit) as host. After Ubuntu install, I did installed Xfce4 (sudo apt-get install xfce4). Logged in using a Xfce session, and when I logged out, I couldn't see the login box anymore, only the regular gnome background from login screen. Then I restarted the virtual machine, and now I'm not able to see the login box anymore, only the gnome background. Does someone knows how to solve this? Thanks in advance

  • emerge only prints it's parameters along with "Wrong gcc version" message.

    - by Dmitriy Matveev
    Our gentoo server has been left in inconsistent state. I don't know what have been done wrong previously, but now I need to fix the system somehow. I've tried to do revdep-rebuild, but it has failed: ... x11-libs/gksu:0 x11-libs/gtk+:2 x11-libs/gtkglarea:2 x11-libs/libgksu:2 x11-libs/libsvg-cairo:0 x11-libs/qt-gui:4 .......... IMPORTANT: 12 news items need reading for repository 'gentoo'. Use eselect news to read news items. Calculating dependencies... done! emerge: there are no ebuilds to satisfy "gnome-base/gswitchit-plugins:0". emerge: searching for similar names... emerge: Maybe you meant any of these: gnome-base/gswitchit-plugins, gnome-extra/gswitchit-plugins, gnome-base/nautilus? IMPORTANT: 12 news items need reading for repository 'gentoo'. Use eselect news to read news items. revdep-rebuild failed to emerge all packages. you have the following choices: If emerge failed during the build, fix the problems and re-run revdep-rebuild. Use /etc/portage/package.keywords to unmask a newer version of the package. (and remove 5_order.rr to be evaluated again) Modify the above emerge command and run it manually. Compile or unmerge unsatisfied packages manually, remove temporary files, and try again. (you can edit package/ebuild list first) To remove temporary files, please run: rm /var/cache/revdep-rebuild/*.rr I've tried to remove one of the mentioned packages: harley ~ # emerge -C gswitchit-plugins Wrong gcc version = echo -C gswitchit-plugins harley ~ # I don't see any problems with the gcc, but emerge isn't working: harley ~ # gcc --version gcc (Gentoo 4.5.2 p1.0, pie-0.4.5) 4.5.2 Copyright (C) 2010 Free Software Foundation, Inc.

  • Install GNU Emacs GUI in Fedora

    - by FLW
    I've installed the "emacs" package from yum, but typing emacs at the terminal doesn't launch the GUI version. I was under the impression it installed by default, and emacs -nw would be used for the terminal version. Is there a GUI package available for Fedora 14 (GNOME)? I couldn't find "emacs-gtk" or "emacs-gnome" or any X packages with yum search emacs-. Edit: To clarify, this is about GNU Emacs and not XEmacs.
