  • Error in eclipse on run android project

    - by Larz
    I am trying to get a simple hello world android project working in eclipse using an android emulator. I have been using the examples on developer.android.com. I actually did have a hello world app working. I then modified it's xml files to have a text input field and a button as in the second example shows on that site. This failed to run on the emulator. I then went back and tried to create another simple hello world project, but it fails to run. The console says "Waiting for HOME ('android.process.acore') to be launched, but nothing happens or sometimes a messenger in the emulator says "unfortunately Android Wear has stopped". Below is a sample error filter on the log file. I find trying to debug this is something new to me and I am not sure the best way to go about it. I am just trying to learn some basic android developer skills. 05-30 16:19:07.336: E/SELinux(469): SELinux: Loaded file_contexts from /file_contexts, 05-30 16:19:07.336: E/SELinux(469): digest= 05-30 16:19:07.376: E/SELinux(469): b0 05-30 16:19:07.376: E/SELinux(469): 4b 05-30 16:19:07.756: E/SELinux(469): 03 05-30 16:19:07.756: E/SELinux(469): 4a 05-30 16:19:07.826: E/SELinux(469): 73 05-30 16:19:07.886: E/SELinux(469): ab 05-30 16:19:07.886: E/SELinux(469): 6d 05-30 16:19:07.896: E/SELinux(469): 46 05-30 16:19:07.896: E/SELinux(469): b4 05-30 16:19:07.896: E/SELinux(469): a5 05-30 16:19:07.896: E/SELinux(469): 73 05-30 16:19:07.896: E/SELinux(469): 8a 05-30 16:19:07.896: E/SELinux(469): ee 05-30 16:19:07.896: E/SELinux(469): ac 05-30 16:19:07.906: E/SELinux(469): 68 05-30 16:19:07.906: E/SELinux(469): ff 05-30 16:19:07.906: E/SELinux(469): 04 05-30 16:19:07.906: E/SELinux(469): dc 05-30 16:19:07.906: E/SELinux(469): b8 05-30 16:19:07.906: E/SELinux(469): a2 05-30 16:19:11.806: E/SensorManager(511): sensor or listener is null 05-30 16:19:16.196: E/BluetoothAdapter(378): Bluetooth binder is null 05-30 16:19:16.206: E/BluetoothAdapter(378): Bluetooth binder is null 05-30 16:19:17.186: E/WVMExtractor(54): Failed to open libwvm.so: dlopen failed: library "libwvm.so" not found 05-30 16:19:17.776: E/AudioCache(54): Error 1, -2147483648 occurred 05-30 16:19:17.796: E/SoundPool(378): Unable to load sample: (null) 05-30 16:19:18.536: E/AudioCache(54): Error 1, -2147483648 occurred 05-30 16:19:18.546: E/SoundPool(378): Unable to load sample: (null)

  • Ubuntu 12.04 Very slow especially with Android Studio

    - by Nada
    I have an old laptop with the following specification: Memory: 485 MiB, Processor: Genuine intel CPU T2300 @ 1.66 GHz ×2, OS Type: 32 bit, Disk: 78.1 GB, I installed on it Ubuntu 12.04 LTS and I noticed that the overall system is very slow in responding. I tried to search about that in the internet and I found some articles talking about how to make Ubuntu 12.04 LTS run fast I applied all what they said including download LXDE desktop environment and then nothing different in the system response time. Then I need to develop some android applications so, I download Android Studio (Beta) 0.8.6. The problem became worse than before whenever I tried to open the Android Studio the screen is frozen for some minutes then it took time to download the projects and initialize the work space also, when I tried to move the cursor he is move very slowly. When I tried to run my first application on the AVD it took three hours and still not run yet. I delete the Android Studio and install it again several times, I was trying to solve the problem but still nothing change. Please if you have any suggestions that may help me make my laptop and Android Studio work faster I will appreciate it for you. Thank you in advance.

  • iPad 3 and the case for Android tablet [closed]

    - by ucas
    I have here a case for Android tablet of 10/10.2 inches. I want to know whether I can fit iPad 3 into that case. In fact, I am concerned about the thickness of iPad because that case got grasps which keeps the tablet steady. So, whether iPad is as slim as Android tablet? In the description of the case is written-"Compatible With Android 10" and 10.2" Tablet PCs (aPad/ePad)." What are these: aPad/ePad? Cheers

  • Wifi in android-x86 with virtual box [closed]

    - by Abhishek
    I am trying to run android-x86 in Virtualbox, I am using a laptop which connects to internet via WiFi. When the android starts in virtual box, it does not recognize the host wireless connection or in other words does not identify the wireless network at all. So I got a TP-Link wireless USB adapter connected to the laptop and configured wireless controller in USB for the VM. But sadly I found that the wireless is disabled as soon as the Android VM starts. I am stuck on how to let android running in Virtualbox identify my Wifi. Any guidelines or set up instructions would be greatly helpful.

  • Installation error: INSTALL_FAILED_OLDER_SDK in eclipse

    - by user3014909
    I have an unexpe`ted problem with my Android project. I have a real android device with ice_cream sandwich installed. My app was working fine during the development but after I added a class to the project, I got an error: Installation error: INSTALL_FAILED_OLDER_SDK The problem is that everything is good in the manifest file.

  • Android ListView style

    - by xger86x
    Hi, I have a question about list views. I hope someone knows the solution, because I have been trying to solve this problem all weekend. I have a custom list view in which every row have a custom .xml (item_row.xml) with a set color background for the row item. <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="70dip" android:orientation="vertical" android:background="@drawable/list_bg"> The problem is that when I try to make a selector for the list. I want two things: When the item is focused, the typical orange rectangle should appear over it, and the same When the item is pressed. I have proved with a selector and a custom style but all I get is or the selector doesn't appear or the selector covering the item so I can't see it. If anyone could help me with finding the right code I would be very grateful. Thanks

  • sqllite and populating list view, android

    - by Rob Bushway
    I am populating a text and list view from a sqllite database. The data is populating from the cursor correctly (I see the list filling with text rows), but I'm not able to see the actual text in the rows - all I see are empty rows.

  • Android vertical line xml

    - by Kaspa
    Hello, I'm trying to figure out how to define a verical line (1px thick) to be used as a drawable. to make a horizontal one, it's pretty straightforward: <shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="line"> <stroke android:width="1dp" android:color="#0000FF"/> <size android:height="50dp" /> </shape> The question is, how to make this line vertical? Yes, there are workarounds, such as drawing a rectangle shape 1px thick, but that complicates the drawable xml, if it consists of multiple <item> elements. Anyone had any chance with this?

  • python union of 2 nested lists with index

    - by sbas
    I want to get the union of 2 nested lists plus an index to the common values. I have two lists like A = [[1,2,3],[4,5,6],[7,8,9]] and B = [[1,2,3,4],[3,3,5,7]] but the length of each list is about 100 000. To A belongs an index vector with len(A): I = [2,3,4] What I want is to find all sublists in B where the first 3 elements are equal to a sublist in A. In this example I want to get B[0] returned ([1,2,3,4]) because its first three elements are equal to A[0]. In addition, I also want the index to A[0] in this example, that is I[0]. I tried different things, but nothing worked so far :( First I tried this: Common = [] for i in range(len(B)): if B[i][:3] in A: id = [I[x] for x,y in enumerate(A) if y == B[i][:3]][0] ctdCommon.append([int(id)] + B[i]) But that takes ages, or never finishes Then I transformed A and B into sets and took the union from both, which was very quick, but then I don't know how to get the corresponding indices Does anyone have an idea?

  • nested for loop

    - by Gary
    Hello, Just learning Python and trying to do a nested for loop. What I'd like to do in the end is place a bunch of email addresses in a file and have this script find the info, like the sending IP of mail ID. For now i'm testing it on my /var/log/auth.log file Here is my code so far: #!/usr/bin/python # this section puts emails from file(SpamEmail) in to a array(array) in_file = open("testFile", "r") array = in_file.readlines() in_file.close() # this section opens and reads the target file, in this case 'auth.log' log = open("/var/log/auth.log", "r") auth = log.readlines() for email in array: print "Searching for " +email, for line in auth: if line.find(email) > -1: about = line.split() print about[0], print Inside 'testfile' I have the word 'disconnect' cause I know it's in the auth.log file. It just doesn't find the word 'disconnect'. In the line of "if line.find(email) -1:" i can replace email and put "disconnect" the scripts finds it fine. Any idea? Thanks in advance. Gary

    I'm new to C++, so bear with me. I have a generic class called A. A has a nested class called B. A contains a method called getB(), which is supposed to return a new instance of B. However, I can't get my code to compile. Here's what it looks like:#include A.h template <class E> class A { public: class B { public: int data; }; B * getB(); }; A.cpp #include "A.h" template <class E> A<E>::B * A::getB() { return new B(); } When I try to compile this, I get the following error: error: expected constructor, destructor, or type conversion before '*' token Does anybody know what I'm doing wrong? Thanks, helixed

  • Nasty deep nested loop in Rails

    - by CalebHC
    I have this nested loop that goes 4 levels deep to find all the image widgets and calculate their sizes. This seems really inefficient and nasty! I have thought of putting the organization_id in the widget model so I could just call something like organization.widgets.(named_scope), but I feel like that's a bad short cut. Is there a better way? Thanks class Organization < ActiveRecord::Base ... def get_image_widget_total total_size = 0 self.trips.each do |t| t.phases.each do |phase| phase.pages.each do |page| page.widgets.each do |widget| if widget.widget_type == Widget::IMAGE total_size += widget.image_file_size end end end end end return total_size end ... end

  • Ruby on Rails - nested attributes: How do I access the parent model from child model

    - by TMaYaD
    I have a couple of models like so class Bill < ActiveRecord::Base has_many :bill_items belongs_to :store accepts_nested_attributes_for :bill_items end class BillItem <ActiveRecord::Base belongs_to :product belongs_to :bill validate :has_enough_stock def has_enough_stock stock_available = Inventory.product_is(self.product).store_is(self.bill.store).one.quantity errors.add(:quantity, "only #{stock_available} is available") if stock_available < self.quantity end end The above validation so obviously doesn't work because when I'm reading the bill_items from nested attributes inside the bill form, the attributes bill_item.bill_id or bill_item.bill are not available before being saved. So how do I go about doing something like that?

  • Android draw using SurfaceView and Thread

    - by Morten Høgseth
    I am trying to draw a ball to my screen using 3 classes. I have read a little about this and I found a code snippet that works using the 3 classes on one page, Playing with graphics in Android I altered the code so that I have a ball that is moving and shifts direction when hitting the wall like the picture below (this is using the code in the link). Now I like to separate the classes into 3 different pages for not making everything so crowded, everything is set up the same way. Here are the 3 classes I have. BallActivity.java Ball.java BallThread.java package com.brick.breaker; import android.app.Activity; import android.os.Bundle; import android.view.Window; import android.view.WindowManager; public class BallActivity extends Activity { private Ball ball; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN); ball = new Ball(this); setContentView(ball); } @Override protected void onPause() { // TODO Auto-generated method stub super.onPause(); setContentView(null); ball = null; finish(); } } package com.brick.breaker; import android.content.Context; import android.graphics.Bitmap; import android.graphics.BitmapFactory; import android.graphics.Canvas; import android.view.SurfaceHolder; import android.view.SurfaceView; public class Ball extends SurfaceView implements SurfaceHolder.Callback { private BallThread ballThread = null; private Bitmap bitmap; private float x, y; private float vx, vy; public Ball(Context context) { super(context); // TODO Auto-generated constructor stub bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ball); x = 50.0f; y = 50.0f; vx = 10.0f; vy = 10.0f; getHolder().addCallback(this); ballThread = new BallThread(getHolder(), this); } protected void onDraw(Canvas canvas) { update(canvas); canvas.drawBitmap(bitmap, x, y, null); } public void update(Canvas canvas) { checkCollisions(canvas); x += vx; y += vy; } public void checkCollisions(Canvas canvas) { if(x - vx < 0) { vx = Math.abs(vx); } else if(x + vx > canvas.getWidth() - getBitmapWidth()) { vx = -Math.abs(vx); } if(y - vy < 0) { vy = Math.abs(vy); } else if(y + vy > canvas.getHeight() - getBitmapHeight()) { vy = -Math.abs(vy); } } public int getBitmapWidth() { if(bitmap != null) { return bitmap.getWidth(); } else { return 0; } } public int getBitmapHeight() { if(bitmap != null) { return bitmap.getHeight(); } else { return 0; } } public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) { // TODO Auto-generated method stub } public void surfaceCreated(SurfaceHolder holder) { // TODO Auto-generated method stub ballThread.setRunnable(true); ballThread.start(); } public void surfaceDestroyed(SurfaceHolder holder) { // TODO Auto-generated method stub boolean retry = true; ballThread.setRunnable(false); while(retry) { try { ballThread.join(); retry = false; } catch(InterruptedException ie) { //Try again and again and again } break; } ballThread = null; } } package com.brick.breaker; import android.graphics.Canvas; import android.view.SurfaceHolder; public class BallThread extends Thread { private SurfaceHolder sh; private Ball ball; private Canvas canvas; private boolean run = false; public BallThread(SurfaceHolder _holder,Ball _ball) { sh = _holder; ball = _ball; } public void setRunnable(boolean _run) { run = _run; } public void run() { while(run) { canvas = null; try { canvas = sh.lockCanvas(null); synchronized(sh) { ball.onDraw(canvas); } } finally { if(canvas != null) { sh.unlockCanvasAndPost(canvas); } } } } public Canvas getCanvas() { if(canvas != null) { return canvas; } else { return null; } } } Here is a picture that shows the outcome of these classes. I've tried to figure this out but since I am pretty new to Android development I thought I could ask for help. Does any one know what is causing the ball to be draw like that? The code is pretty much the same as the one in the link and I have tried to experiment to find a solution but no luck. Thx in advance for any help=)

  • iPhone Setting ViewController nested in NSMutableArray

    - by Peter George
    Hello I'm trying to set attributes for a viewcontroller nested inside a NSMutableArray, for example I have 3 ViewController inside this array: FirstViewController *firstViewController = [FirstViewController alloc]; SecondViewController *secondViewController = [SecondViewController alloc]; ThirdViewController *thirdViewController = [ThirdViewController alloc]; NSMutableArray *viewControllerClasses = [[NSMutableArray alloc] initWithObjects: firstViewController, secondViewController, thirdViewController, nil]; for (int x=0; x<[viewControllerClasses count]; x++) { // as an example to set managedObjectContext I otherwise would set firstViewController.managedObjectContext = context; [viewControllerClasses objectAtIndex:x].managedObjectContext = context; } But this results in an error: Request for member "managedObjectContext" in something not a structure or union. Shouldn't be "firstViewController" be the same as [viewControllerClasses objectAtIndex:0]?

  • Lua class instance with nested tables

    - by Anonnobody
    Hello, Simple lua game with simple class like so: creature = class({ name = "MONSTER BADDY!", stats = { power = 10, agility = 10, endurance = 10, filters = {} }, other_things = ... }) creatureA = creature.new() creatureB = creature.new() creatureA.name = "Frank" creatureB.name = "Zappa" creatureA.stats.agility = 20 creatureB.stats.power = 12 -- blah blah blah Non table values are individual to each instance, but table values are shared among all instances and if I modify a stats.X value in one instance, all other instances see the same stats table. Q1: Is my OO implementation flawed? I tried LOOP and the same result occured, is there a fundamental flaw in my logic? Q2: How would you have each instance of creature have it's own stats table (and sub tables)? PS. I cannot flatten my class table as it's a bit more complicated than the example and other parts of the code are simplified with this nested table implementation. Thanks a bunch.

  • ADT will not allow creation of Android Activity

    - by NewShelbyWoo
    I installed the ADT bundle from http://developer.android.com/sdk/index.html yesterday, and I was following a basic Hello World tutorial. I created a new Android Application Project with a Blank Activity named MainActivity. The resulting project has an empty src folder and empty res\layout folder. There is a R.java file in the gen folder but it has no reference to MainActivity. This is what the SDK manager says I have installed Android SDK Tools v 22.6 Android SDK Platform-tools v 19.0.1 Android SDK Build-tools v 19 SDK Platform v 3 ARM EABI v7a System Image v 2 Android Support Library v 19.0.1 Google USB Driver v 9 I also tried manually creating an activity by right clicking the src folder and going to Android Activity, but when I hit Finish on the creation wizard, nothing happens. Does anyone have any clues as to what's going on? Did I miss a key component to install or something?

  • Nested form problem in Rails : NoMethodError in Show

    - by brianheys
    I'm trying to build a simple product backlog application to teach myself Rails. For each product, there can be multiple product backlog entries, so I want to create a product view that shows the product information, all the backlog entries for the product, and includes a nested form for adding more backlog entries. Everything works until I try to add the form to the view, which then results in the following error: NoMethodError in Products#show Showing app/views/products/show.html.erb where line #29 raised: undefined method `pblog_ref' for #<Product:0x10423ba68> Extracted source (around line #29): 26: <%= f.error_messages %> 27: <p> 28: <%= f.label :pblog_ref %><br /> 29: <%= f.text_field :pblog_ref %> 30: </p> 31: <p> 32: <%= f.label :product %><br /> The product view where the problem is reported is as follows (the partial works fine, so I won't include that code): <h1>Showing product</h1> <p> <b>Product ref:</b> <%=h @product.product_ref %> </p> <p> <b>Description:</b> <%=h @product.description %> </p> <p> <b>Owner:</b> <%=h @product.owner %> </p> <p> <b>Status:</b> <%=h @product.status %> </p> <h2>Product backlog</h2> <div id="product-backlog"> <%= render :partial => @product.product_backlogs %> </div> <% form_for(@product, ProductBacklog.new) do |f| %> <%= f.error_messages %> <p> <%= f.label :pblog_ref %><br /> <%= f.text_field :pblog_ref %> </p> <p> <%= f.label :product %><br /> <%= f.text_field :product %> </p> <p> <%= f.label :description %><br /> <%= f.text_field :description %> </p> <p> <%= f.label :owner %><br /> <%= f.text_field :owner %> </p> <p> <%= f.label :status %><br /> <%= f.text_field :status %> </p> <p> <%= f.submit 'Create' %> </p> <% end %> <%= link_to 'Edit', edit_product_path(@product) %> | <%= link_to 'Back', products_path %> This is the Product model: class Product < ActiveRecord::Base validates_presence_of :product_ref, :description, :owner has_many :product_backlogs end This is the ProductBacklog model: class ProductBacklog < ActiveRecord::Base belongs_to :product end These are the routes: map.resources :product_backlogs map.resources :products, :has_many => :product_backlogs I've checked what I'm doing against the Creating a weblog in 15 minutes with Rails 2 screencast, and in principle I seem to be doing the same thing as him - only his nested comments form works, and mine doesn't! I hope someone can help with this, before I turn mad! I'm sure it's something trivial.

  • Bash Nested Loops, mixture of dates and numbers

    - by Saleh
    Hi, I am trying to output a range of commands with different dates and numbers associated. for each hour eg. Output im trying to do in a loop is: shell.sh filename<number e.g. between 1-24> <date e.g. 20100928> <number e.g. between 1-24> <id> So basically the the above will generate an output done 24 times for each particular day with a unique 4 digit id. I was thinking of having a nested loop, as the batch number needs to be unique. can anyone help?
