Global Exception handling in Android

To be able to catch any exception you may encounter that isn’t part of a try-catch-clause, you can use the Thread.setDefaultUncaughtExceptionHandler( Thread. UncaughtExceptionHandler ) method.

In the handler you can then perform whatever action you want. Don’t forget to call “System.exit()” though, because otherwise this won’t work!

A simple example:

public class SomeActivity extends Activity {
private static final String LOG_TAG = "SomeActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
@Override
public void uncaughtException(Thread paramThread, Throwable paramThrowable) {
Log.e(LOG_TAG, "OMG! Uncaught Exception!");
// Without calling System.exit() this will not work.
System.exit(2);
}
});
}
}
