Does anyone know why this happens? I see this crash reported by my app but I have no idea what it is. java.lang.NoClassDefFoundError: android.app.ANRManagerProxy Thread: Binder_3, Exception: java.lang.NoClassDefFoundError: android.app.ANRManagerProxy at android.app.ANRManagerNative.asInterface(ANRManagerNative.java:30) at android.app.ANRManagerNative$1.create(ANRManagerNative.java:94) at android.app.ANRManagerNative$1.create(ANRManagerNative.java:88) at android.util.Singleton.get(Singleton.java:34) at android.app.ANRManagerNative.getDefault(ANRManagerNative.java:37) at android.os.MessageLogger

Meet a ANR in sharedPreferences, don't know how to locate the problem. Here are three parts from trace, most of other threads are "WAIT" or "TIMED_WAIT". "main" thread is blocked because of countdownlatch.await(). 2nd thread "pool-1-thread-1" waiting for the fsync. The last one is trying to read something. I think 2nd thread has blocked main thread, because if this one can't finish, it won't invoke countdownlatch.countdown(), so the main thread have to wait. But I can't figure out why it stops in the fsync. Is the 3rd thread related to this? thread1 "main" prio=5 tid=1 WAIT | group="main"

How can I recursively scan directories in Android and display file name(s)? I'm trying to scan, but it's slow (force close or wait). I'm using the FileWalker class given in a separate answer to this question . You should almost always access the file system only from a non-UI thread. Otherwise you risk blocking the UI thread for long periods and getting an ANR. Run the FileWalker in an AsyncTask 's doInBackground() . This is a slightly optimized version of FileWalker: public class Filewalker { public void walk(File root) { File[] list = root.listFiles(); for (File f : list) { if (f.isDirectory

Is the ANR an exception, an error or what? Can we actually catch it in a try{} catch(){} structure? rogerstone ANR (Application Not Responding) is not exactly an error. It is shown when your application is very sluggish and takes a lot of time to respond, thus making the user wait. The user won't appreciate if your application makes them wait for a long time. So, the Android framework gives the user an option of closing your application. http://developer.android.com/guide/practices/design/responsiveness.html This occurs when you are doing long running operations on the main thread. The system

Every ANR dump lists the states of all threads at the time of the ANR. I know what WAIT means but what do SUSPENDED and MONITOR mean? Thanks in advance... Summary of Dalvik thread states: INITIALIZING - not yet running. STARTING - not yet running, but almost there. ZOMBIE - deceased (you shouldn't see this). RUNNING (a/k/a RUNNABLE) - thread is actively running. The VM has to suspend all threads to do the stack dump, so you generally won't see this for any thread other than the one that is dumping the stack. WAIT - the thread called wait(), and is patiently waiting. TIMED_WAIT - thread called

I have two button's in the main menu. I invoking the camera when I press the 1st button. Here I didn't get any issue. Camera working properly. After taking the picture, I come back in to main menu and again I press the 1st button. Here I got the issue. Camera invoking properly. But I got ANR error (Reason: keyDispatchingTimedOut) while i'm taking the picture. How to resolve this issue? Edit:: I'm using following code, Button Listener , Button imageButton = (Button) findViewById(R.id.button1); imageButton.setOnClickListener(new View.OnClickListener() { public void onClick(View arg0) { Intent

I have an android app, which listens to a socket from the server and retrieves data in json format and save data in the database. Resource cursor adapter is used to display the data in a list. When the app is idle for 10 minutes or more, it is not reponding. Any solutions? ANR occurs when the main thread is blocked for a few time. Specifically, 5 seconds in an Activity, 10 seconds in a BroadcastReceiver and 20 seconds in a Service. So, to avoid ANR , you need to ensure that you don't do something like these in you UI thread: reading or writing files , connecting the internet , operating
