I got an null pointer exception on Android 3.2 emulator on a simple Android project created by Wizerd with a service in separated process, when I switch between "Stretch to fill screen" to "Zoom to fill screen". This crash will *not* happen if the service is put into the same process with main activity, namely "android:process" attribute not specified. While it only happens when I add "android:process" to manifest file for my test service.
The exception is: FATAL EXCEPTION: main java.lang.NullPointerException at android.view.WindowManagerImpl.reportNewConfiguration(WindowManagerImpl.java: 427) at android.app.ActivityThread.handleUpdatePackageCompatibilityInfo(ActivityThread.java: 2801) at android.app.ActivityThread.access$2700(ActivityThread.java: 122) at android.app.ActivityThread $H.handleMessage(ActivityThread.java:1151) at android.os.Handler.dispatchMessage(Handler.java:99) at android.os.Looper.loop(Looper.java:132) at android.app.ActivityThread.main(ActivityThread.java:4123) at java.lang.reflect.Method.invokeNative(Native Method) at java.lang.reflect.Method.invoke(Method.java:491) at com.android.internal.os.ZygoteInit $MethodAndArgsCaller.run(ZygoteInit.java:841) at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:599) at dalvik.system.NativeStart.main(Native Method) My test code: TestActivity.java (Generated by Wizerd) ===================== package com.test; import android.app.Activity; public class TestActivity extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); Intent intent = new Intent(this, TestService.class); startService(intent); } } ===================== TestService.java (Most of the functions are empty) ===================== Package com.test; import android.content.ComponentName; public class TestService extends Service { private boolean m_connected = false; private ServiceConnection m_connInitService = new ServiceConnection() { public void onServiceConnection(ComponentName className, IBinder service) { m_connected = true; } public void onServiceDisconnected(ComponentName className) { } }; public static class TestServiceBinder extends Binder { } public IBinder onBind(Intent intent) { return new TestServiceBinder(); } public void onDestroy() { super.onDestroy(); } public int onStartCommand(Intent intent, int flags, int startId) { return 1; } } ===================== If I run the test app without service or with service in the same process (with main activity) the screen compatibility switch will *not* cause any problem. However, I do not understand why service can cause system exception during screen compatibility switch. Is this because service process is a non-UI process? Which could potentially triggers a bug inside the Android core code? -- You received this message because you are subscribed to the Google Groups "Android Developers" group.
