I tried to start an activity with an implicit intent after an uncaught exception with the unCaughtExceptionHandler. The intent should start an Activity as a Dialog in the same app that has crashed. This corresponds to the example listed in this thread:
Need to handle uncaught exception and send log file
I call the original unCaughtExceptionHandler at the end of my own handler procedure, like this:
public class ThisApplication extends Application
{
Thread.UncaughtExceptionHandler originalUncaughtExceptionHandler;
@Override
public void onCreate ()
{
originalUncaughtExceptionHandler = Thread.getDefaultUncaughtExceptionHandler();
Thread.setDefaultUncaughtExceptionHandler (new Thread.UncaughtExceptionHandler()
{
@Override
public void uncaughtException (Thread thread, Throwable e)
{
handleUncaughtException (thread, e);
}
});
super.onCreate();
}
public void handleUncaughtException (Thread thread, Throwable e)
{
e.printStackTrace();
Intent intent = new Intent ();
intent.setAction ("de.mydomain.myapp.action.PROCESS_LOG");
intent.setFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
if (intent.resolveActivity(getPackageManager()) == null) {
Log.d("ThisApplication","No receiver");
} else {
Log.d("ThisApplication", "Intent start");
startActivity(intent);
}
originalUncaughtExceptionHandler.uncaughtException(thread, e);
}
}
The result is, that after an Exception the standard Dialog is displayed that says something like "Unfortunately App xxx was closed". Behind that Dialog, in the background, I can see my Dialog that should be started with this intent "PROCESS_LOG". So obviously is was started, but the problem is, that after the standard Dialog has been closed, my custom dialog also closes. If I add
android:launchMode="singleInstance"
in the manifest of the dialog activity, the dialog is hidden, too, but it can be activated again when the app is selected from the recent apps menu. This seems to me as if the dialog is not started fully independently from the former app process/task.
Can somebody say what I did wrong?
This is the manifest part of the dialog activity:
<activity
android:name=".ProcessLogActivity"
android:windowSoftInputMode="stateHidden"
android:theme="@style/ProcessLogActivity"
android:process=":report_process"
>
<intent-filter>
<action android:name="de.mydomain.myapp.action.PROCESS_LOG" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
The corresponding style:
<style name="ProcessLogActivity" parent="@style/Theme.AppCompat.Light.Dialog">
</style>
This is the Dialog Activity class:
public class ProcessLogActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature (Window.FEATURE_NO_TITLE);
setFinishOnTouchOutside (false);
Log.d("ThisApplication", "Intent received");
setContentView(R.layout.activity_process_log);
}
}
