问题 We're building an app that does a lot of animations and downloads a lot of images. After a certain amount of transactions (a predictable number), the app is crashing with the error: A/Looper: Could not create wake pipe. errno=24 We don't use Looper in our code, but a few of the libraries we use do use Looper: ActionBarSherlock: I don't think this is the culprit facebook: I don't think this is the culprit nineoldandroid: This animation library could be the culprit volley: This is probably not

The code at the bottom of this post is triggered by the following line of code. new MasterClickAsyncTask(main).execute(position); The doInBackground portion of code below calls a method containing a for loop, hence the need for Looper.prepare(). This code runs fine the first few times it is called but then it throws the following error: 10-15 22:50:24.752: ERROR/AndroidRuntime(9258): Caused by: java.lang.RuntimeException: Only one Looper may be created per thread I've tried putting Looper.getMainLooper().quit(); and a few other things like this in various parts of the AsyncTask but this has

Android: TimerTask scheduled for repetition getting fired only once

问题 Ok this is a very weird problem I am having, and I'm pretty sure that I am messing up somewhere, but I can't quite figure out where. What I am trying is - Schedule a Timer to execute a TimerTask every five seconds The TimerTask in turn executes an AsyncTask (which in this case simple sleeps for a second before returning the static count of the number of AsyncTasks). Finally, the aforementioned count is updated in the UI. And of course, the appropriate Handler s and Runnable s have been used

Specifics on using Looper.prepare() in Android

问题 I'm having a bit of trouble understanding how to use the Looper prepare() / loop() / quit() logic. I have three threads: one is the UI thread, one is a game logic thread and the last is a network communication thread (a background thread, lives only while being used). The game thread has many dependencies on the results of the network calls, so I wanted to spin the network thread off of the game thread and have a Handler post the result back. Of course, since the UI thread is not involved I

Calling Looper more than once causes “sending message to a Handler on a dead thread”

问题 I am using an Executor [fixed thread pool] with my own ThreadFactory that adds a Looper: Handler HANDLER = new Handler(); Executor THREADS = Executors.newFixedThreadPool(THREAD_POOL_SIZE, new ThreadFactory() { @Override public Thread newThread(Runnable runnable) { return new MyThread(new Runnable() { @Override public void run() { Looper.prepare(); runnable.run(); } }); } }); private static class MyHandler extends Handler { public boolean fail; public void handleMessage(Message msg) { switch

Android: difference between getMainLooper() and Looper.myLooper()

由 烈酒焚心 提交于 2019-12-04 05:10:56
问题 I'm now trying to resurrect one project. There was an exception on getMainLooper()... I thought that may be there's a problem with MainLooper initialization and added Looper.prepareMainLoop() before that. Exception telling me that there's already a looper for that object was thrown... Then I tried to replace getMainLooper() with Looper.myLooper() and it worked... But I didn't understand why=) In fact I don't get the difference between this two things. I think that on the place where
