• Bitmap Crashing upon going back and re-entering Activity

  - by dagonal

  Hello, I'm not sure what is causing this...I have two Activities, first has a button that goes to the second. The second creates a Bitmap object, assigns it a picture from the sdcard and loads it into an ImageView. Problem is when I go into the second Activity, then press the back button, and then go back into the second Activity, it crashes. I have no clue why. I did an extensive google search but to no avail. I can post the source code if you want. Please let me know. Thanks in advance! I got this from the LogCat: "E/dalvikvm( 4869): Unable to open stack trace file '/data/anr/traces.txt': Permission denied" I'm not sure how to get the stack trace.

• Android how to create notification that resumes activity

  - by Adam Praiswater

  I a have a notification in a receiver that fires off fine, but it restarts the activity (thus clearing the edittexts and resetting the toggle button) How can i set it so that when its tapped on it resumes the activity rather that clearing and resetting everything? My current code doesnt work. Current Code String currentDateTimeString = DateFormat.getDateTimeInstance().format(new Date()); Intent intenti= new Intent(context, Locator.class); intenti.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_SINGLE_TOP); PendingIntent contentIntent = PendingIntent.getActivity(context, 0, intenti, 0); NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context) .setSmallIcon(R.drawable.xxxxxxnotifyicon) .setContentTitle("xxxxxxx Link") .setContentText("Auto Check In Complete at " + currentDateTimeString); mBuilder.setContentIntent(contentIntent); mBuilder.setDefaults(Notification.DEFAULT_SOUND); mBuilder.setAutoCancel(true); NotificationManager mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE); mNotificationManager.notify(1, mBuilder.build());

• how to invoke an activity of a library project from an android apps

  - by Austin

  I have an open source android code that I need to use in my android apps. It has all the source code as well as resource files, manifest files and class path. It can be compiled as a separate android apps. I have constraints for using the open source. 1. I can't change a single line of code. 2. I can't use it as a separate apps. These constraints are non negotiable. What I have done is I have compiled the open source as class library(in Eclipse: Project Properties-Android- Tick check box Is Library). This has resulted in generation of .class files(in bin) for the java files and resource files. This open source has an android activity that i want to open from my application. So I have linked the directory of these sets of class files in the source section of my java build path( in .classpath). I have declared the activity in my manifest file with proper action intent filters. Now when I am trying to call activity from my code, its not working. Cleaning and rebuilding doesn't help. However, if I build the open source project and my apps in the same workspace of eclipse and link the open source in my apps in exact same manner it works fine. I am not able to identify the difference. All settings seems to be same(all files are identical in both the cases). But only in the second case it works. I have tried it as jar file also. I have build the open source as project library and exported it into a jar file(excluding manifest file). But in that case I am getting the following error UNEXPECTED TOP-LEVEL EXCEPTION: java.lang.IllegalArgumentException: already added: .... Conversion to Dalvik format failed with error 1 This I guess is coming because the android library(2.2) has been included twice in my apps( one for building my apps & another for building the open source). I dont know how to avoid this. Cleaning the project doesn't help. What i require is to use the open source and invoking it's activities in my apps without violating the constraints. If i can use the open source as bunch of .class files then great, or else any other way will do fine. Please look into it and let me know. Thanks

• Contacts activity doesn't return data

  - by Mike

  In my app I simply open the list of activities and when a contact is clicked I attempt to retrieve the name of the contact selected and put it into a string. The app crashes in the onActivityResult() function. I do have the READ_CONTACTS permission set. /** * Opens the contacts activity */ public void openContacts() { Intent intent = new Intent(Intent.ACTION_PICK, People.CONTENT_URI); startActivityForResult(intent, PICK_CONTACT); } @Override public void onActivityResult(int reqCode, int resultCode, Intent data) { super.onActivityResult(reqCode, resultCode, data); switch (reqCode) { case (PICK_CONTACT) : if (resultCode == Activity.RESULT_OK) { Uri contactData = data.getData(); Cursor c = managedQuery(contactData, null, null, null, null); //NullPointerException thrown here, line 102 if (c.moveToFirst()) { String name = c.getString(c.getColumnIndexOrThrow(People.NAME)); FRIEND_NAME = name; showConfirmDialog(name); } } break; } } The following logcat error logs are returned: Any help is appreciated. Thanks

• Invoking activity that is located in a jar

  - by Sebi

  hi i tried to invoke another activity from my main acitivty which is located in a jar file. Class clazz = Class.forName(getPackageName() + "." + getActivityName()); startActivity(new Intent(this, clazz)); Im doing it this way because i only know the name of the class. This works fine but unfortunately, all resource files can't be found while loading the activity from the jar file. at the first occurence of loading a res file there is a ResourceNotFoundException: 04-30 11:18:46.944: ERROR/AndroidRuntime(1749): Caused by: android.content.res.Resources$NotFoundException: Resource ID #0x7f040006 any hints for that? thanks!

• Android: Strange out of memory issue

  - by Chrispix

  I am not sure where to start to explain this one. I have a list view with a couple image buttons on each row. When you click the list row, it launches a new activity. If you review some of my other posts, I have had to build my own tabs because of an issue w/ the camera layout. The activity that gets launched for result is a map. If I click on my button to launch the image preview (load an image off the sd card) the application returns from the activity back to the listview activity to the result handler to relaunch my new activity which is nothing more than an image widget. So here is the issue, the image preview on the list view is being done w/ the cursor & listadapter. This makes it pretty simple, but I am not sure how I can put a resized (i.e. smaller bit size not pixel) image as the src for the imgbutton on the fly. So I just resized the image that came off the phone camera. The issue is that I get an out of memory error when it tries to go back and re-launch the 2nd activity. ** My question : is there a way I can build the list adapter easily row by row, where I can resize on the fly (bit wise)? - this would be preferable as I also need to make some changes to the properties of the widgets/elements in each row as I am unable to select a row w/ touch screen b/c of focus issue. (I can use roller ball). ** I know I can do an out of band resize and save of my image, but that is not really what I want to do, but some sample code for that would be nice if that is your suggestion. As soon as I disabled the image on the listview it worked fine again. FYI : This is how I was doing it : String[] from = new String[] { DBHelper.KEY_BUSINESSNAME, DBHelper.KEY_ADDRESS, DBHelper.KEY_CITY, DBHelper.KEY_GPSLONG, DBHelper.KEY_GPSLAT, DBHelper.KEY_IMAGEFILENAME + ""}; to = new int[] { R.id.businessname, R.id.address, R.id.city, R.id.gpslong, R.id.gpslat, R.id.imagefilename }; notes = new SimpleCursorAdapter(this, R.layout.notes_row, c, from, to); setListAdapter(notes); Where R.id.imagefilename is a ButtonImage Here is my LogCat 01-25 05:05:49.877: ERROR/dalvikvm-heap(3896): 6291456-byte external allocation too

• Same Title Bar but different View below it in Android?

  - by sunil

  Hi, In one of my Android Application I need to keep the title bar same but the view that is shown in the rest of the screen changes. So, I have taken different Activity for all the views that I need to show and set the title bar in every Activities onCreate method. Now, the problem is that I have a button in the title bar and need to perform certain action on its click event. Writing the same event handling code in every Activity class is very cumbersome. Is there any other way out that whenever there is a click event on that button of the title bar then we can have the same functionality without writing the same code in all the Activity classes. Can we use ViewGroup for that? I don't have much idea about ViewGroup. Is that possible with ViewGroup? If anyone knows the solution then please let me know. Thanks & Regards Sunil

• How can an Android Service know that its not bound to any Activities

  - by tunneling

  I have an Android Service that I would like to keep running even after the last Activity has been popped off the stack, or the User has chosen to do something else. Essentially the Service is listening for changes on a remote server, and I would like to generate a Notification if and only if an Activity from the app isn't running(or visible). In other words, I don't want the Notifications to occur while the User is directly interacting with the app. In the case where the User is directly interacting with the app, the Service will notify the Activity and update appropriate UI elements based on the changes. I plan to implement this through the Observer pattern. How can the Service know if none of apps Activities are bound to it? Thanks, J

• Delete file after sharing via intent.

  - by Matt

  I'm trying to delete a temporary file after sharing it via android's Intent.ACTION_SEND feature. Right now I am starting the activity for a result and in OnActivityResult, I am deleting the file. Unfortunately this only works if I am debugging it with a breakpoint, but when I let it run freely and say, email the file, the email has no attachment. I think what is happening is my activity is deleting the file before it had been emailed. What I don't get is why, shouldn't onActivityResult only be called AFTER the other activity is finished? I have also tried deleting the file in onResume, but no luck. Is there a better way to do this?

  I'm not asking how to find out where a bottleneck is. I just what to know how to check if the harddrive is being used at its limit (and hence causing a bottleneck). Something like top where I can see a usage percentage of CPU and RAM. Is there something like that with which I can monitor harddrive activity? Native linux tools preferred.

• Windows 7 - Wireless Signal Good - Internet Often Says Limited or No Activity

  - by Anthony Trilussa Pizzo

  Hi - I have a New Dell Studio XPS latop that I hooked up in early January of 2010. The Dell Studio XPS laptop is connected to my wireless router (Belkin Wireless N). The router was purchased in Februaru of 2010 because I thought my router was bad (A D-Link router). Comcast is my ISP. Everyday, at random times, the internet will have a good signal (according to the little Win 7 icon on the taskbar) but I will receive a message saying limited or no internet access and I cannot access the internet. I have the internet setup to automatically get an IP and I did the IPCONFIG release / renew but with no success. I even had a WiFi enabled Blackberry right next to my computer and whenever the computer loses an WiFi connection, so does the Blackberry. The router isnt't bad, because the old router did the same thing - giving me limited or no internet access while working sometimes. I also tried using two other laptops in same physical position as my Dell Studio XPS laptop and they have the same problem. I am going crazy trying to figure this out as I have called the Router Company (Belkin), my ISP (Comcast), and my computer maker (Dell). Can anyone offer some suggestions and I can try them as we work through this and maybe one of the suggestion will be right one. Thanks in advance for even reading my problem. I searched for a problem similar to mine on the internet, but I have not been able to keep a steady internet connection. (Side note - I used to have an IBM thinkpad laptop and D - Link router and for years that wireless connection worked FLAWLESSLY, with the same physical set up - the laptop in my bedroom, and the router in the basement.)

• Logging network activity of LAMP server using BASH

  - by Yarin

  I've got a Fedora LAMP server on Amazon EC2 functioning as a HTTP pseudo-proxy (Sorry, don't know the terminology- It's not a true proxy where requests are relayed through apache, rather client requests are being translated by a PHP script, which then sends a new request.) I'd like to be able to fully log the HTTP cycle CLIENT - PROXY PROXY - SERVICE SERVICE - PROXY PROXY - CLIENT I'm hoping to do this using BASH tools- thinking netcat? Looking for advice and examples.

• Is there any online web application for daily activity logs [closed]

  - by user25

  I am looking for daily calendar-like apps, but ones that have some text editor attached for every day. All I want to do is that when I open that page, it should open the text editor for that day and I could enter some data of what I have accomplished, then save it. The next day I'd like it so when I open the application, then I can go to new page, but I have all of the previous day's data to have a look at what I have done. Something like Google calendar, but I need an associated text editor to paste some notes, stuff, etc. on a daily basis with logs.

• MySQL Extremely High Disk Activity (Read Operations)

  - by Jake Schoermer

  I have 1GB Linode VPS with a standard LAMP stack. Apache is tuned fine but for some reason MySQL's disk usage is high. This is causing really slow site load times. RAM and CPU usage are fine. Can anyone give me any pointers on tuning mysql's disk performance? I'm using InnoDB. iotop output is below.

• Monitoring Maximum Process Network Activity

  - by user125973

  We have a collocated server on which we run some OpenVZ hosts. Recently, we have had to pay a lot extra we keep exceeding our bandwidth quota. Our quota is 5 Mb/s but we have spike to almost 50. I looked at the graphs and there are some spikes happening at some intervals. I want to know which process is causing this so I need a tool that monitors the processes and gives me the one with the maximum instant traffic (It doesn't matter how much traffic we have as long as we don't exceed the 5Mb/s quota). Does anyone have a recommendation for this? My hosts are CentOS 5 with OpenVZ so I can see all the containter processes from the host, if that helps in any way.

• Vista locks up after ~10h. of activity

  - by Naomi

  Hi everybody, I am experiencing a problem: Windows Vista completely freezes/locks up lately... It happened today twice - the mouse and keyboard stopped responding and I had to re-boot. I checked the Application Events Log and I see these two errors: Event filter with query "SELECT * FROM __InstanceModificationEvent WITHIN 60 WHERE TargetInstance ISA "Win32_Processor" AND TargetInstance.LoadPercentage 99" could not be reactivated in namespace "//./root/CIMV2" because of error 0x80041003. Events cannot be delivered through this filter until the problem is corrected. and then The following boot-start or system-start driver(s) failed to load: SASDIFSV SASKUTIL I checked Help online and it points to http://technet.microsoft.com/en-us/library/cc756390%28WS.10%29.aspx and suggests Updating the drivers. I'm not sure why would I have problem with drivers and if so, how can I find out which drivers to update? Can you please help me? Thanks in advance.

• Wireless Activity Monitoring for PCI DSS Compliance

  - by dkusleika

  In an effort to be PCI DSS compliant, I took a trustkeeper.net questionnaire. I failed the question that asks Is the presence of wireless access points tested for by using a wireless analyzer at least quarterly or by deploying a wireless IDS/IPS to identify all wireless devices in use? (SAQ #11.1) My only wireless access point is outside my firewall, so even if you cracked my wireless you couldn't get inside my domain (unless you crack that too). My firewall doesn't have IPS and I couldn't tell if it had IDS. I looked around for a wireless analyzer, but what I found was $500, which is a little pricey for my size business. And even if I got it, I'm not sure I would understand what it tells me. Surely there are smaller/less sophisticated businesses that take credit cards and have solved this. My questions are: What are the risks if someone were to crack my wireless? (Could they read all internet traffic? Just wireless traffic? Just use my internet connection?) And what is the best/cheapest way to test my connection point quarterly? Should I buy the $500 analyzer? Domain is Windows Server 2000. Firewall is Sonicwall Pro 2040. Router is 8 port D-link.

• Creating an office network and monitoring all activity without a proxy

  - by Robert

  We are setting up our office network and would like to track all the websites visited by our employees. However, we would not like to use any proxy based solutions. Our work is highly dependent on applications in which you cannot configure a proxy. Hence, the approach we would like to follow is setting up a router inside a computer (something like this : http://www.techrepublic.com/article/configure-windows-server-2003-to-act-as-a-router/5844624) This will also allow us to attach multiple ethernet cards and have redundancy in internet connectivity with complete abstraction from the user about which connection is being used. But most importantly, since all the traffic will be going through the computer (configured as a router) I assume there will be a way to run packet analysis on all the request / responses being made. For example, list all the FTP servers connected to (port 21), give a graph of all the URLs visited per day by frequency. Is there already a software which does this ? Or is it possible to build something like this ?

• Extract sender activity from postfix logs for auditing user

  - by Aseques

  We have a mail user on our postfix server that was using the company mail to send compromising information to the competence. I've been asked to make a report of the actions for that user in the last time. There are tools like pflogsumm and others that can extract statistic data, but I haven't so far find anything useful to get all the info for a user because the data is in multiple lines. I'd like to get something like this: For the sent mail 11/11/11 00:00:00 [email protected] -> [email protected] 11/11/11 00:00:01 [email protected] -> [email protected] For the received mail 10/10/11 00:00:00 [email protected] -> [email protected] 10/10/11 00:00:01 [email protected] -> [email protected] I know I can do a script by myself, but matching the postfix ID for every mail is not something that can be made with a simple grep, and I've a lot of mail history that I have to recheck distributed among diferent files and so on. The source log is the standard postfix format, for example this one... Sep 13 16:15:57 server postfix/qmgr[18142]: B35CB5ED3D: from=<[email protected], size=10755, nrcpt=1 (queue active) Sep 13 16:15:57 server postfix/smtpd[32099]: disconnect from localhost[127.0.0.1] Sep 13 16:15:57 server postfix/smtp[32420]: 58C3E5EC9C: to=<[email protected]>, relay=127.0.0.1[127.0.0.1]:10024, delay=1.4, delays=0.01/0/0/1.4, dsn=2.0.0, status=sent (250 2.0.0 Ok, id=32697-04, from MTA([127.0.0.1]:10025): 250 2.0.0 Ok: queued as B35CB5ED3D) Sep 13 16:15:57 server postfix/qmgr[18142]: 58C3E5EC9C: removed Sep 13 16:15:57 server postfix/smtp[32379]: B35CB5ED3D: to=<[email protected]>, relay=mail.anothercompany.com[123.123.123.163]:25, delay=0.06, delays=0.03/0/0.01/0.02, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 77D0EB6C025) Sep 13 16:15:57 server postfix/qmgr[18142]: B35CB5ED3D: removed

• SQL2005 reporting server: intense security activity

  - by David Wimbush

  On my reporting server the Security log shows large numbers of Logon/Logoff events, often 10 or more, when you run pretty much any report in the Report Manager. Is this normal or is it a classic sign of having the wrong setup? Some system details: Windows Server 2003 R2 SP2, virtual server running under VMWare). SQL Server 2005 SP3 Standard Edition, running databases, Report Manager, and Ananlysis Services cubes. No other major services on the machine (i.e. it's not a domain controller, Exchange server or anything like that). Any ideas, please, guys?

• Windows 7 hangs with 100% disk activity but only when online

  - by jeremy

  I have the same problem as seemingly many other people here, and I think we might all be experiencing the same issue: a compatibility issue in Windows 7 between hard drive and network controller or drivers. I've tried firmware updates of my entire board, wiping my drive and reinstalling from scratch. And yet the problem persists, which suggests it is an operating system error, as the hard drive checks out 100% physically. Additionally, the only time it does not occur is when in safe mode WITHOUT networking. With networking, there are spikes in disc access every so often and a huge flow of processes accessing the disc simultaneously that literally "stick" the disc, and physically jolting my computer unsticks it. Again, this has been tested for hours in a professional service environment, and without network access on, things are fine. As soon as there's network access available, the disc access occasionally cranks up to 100% and sticks everything. I'm using Microsoft Security Essentials, but this also happened under Norton, then McAfee. Again, this happened again after a complete wipe, so the likelihood of malware causing it seems low. I don't visit unsecure sites anyway, as far as I know. This, to me, narrows it down to a Windows 7 process that is somehow repeatedly corrupted, perhaps a corrupt .dll or driver, causing a conflict at the operating system level and temporary hard drive failure. I would encourage anyone who knows more about this stuff (which is probably most people!) to take a shot at this one, and I would encourage anyone else with a sticking hard drive in windows 7 64-bit to check on whether it occurs during safe mode without networking.

• Automatically reboot Windows8 if no internet activity [migrated]

  - by Patrick

  I have a media server located in a very inconvenient part of my house. Occasionally I will have to reset my router or it will reset itself. The issue is the PC loses connectivity for some reason, and I am forced to walk outside, around the house, into the basement, over a bunch of toys and weights and boxes, to push a button to reboot it. I would love to have it check itself every 5-10 minutes and auto reboot if it is unable to ping a given address/IP. Any ideas how to accomplish this?
