Android Uncaught with no white screen

Question

I've wanted to avoid the app crash and then I develped the uncaughtException method to call another activity; it works fine. If the app crashes whatever activity, the uncaughtException is called and then my ErrorActivity is shown up. The problem is when I try to close the app after a crash. When I press the back button, the ErrorActivity is closed, but then a white screen with actionbar shows up and after a few seconds the ErrorActivity is called again. So, there is no way to close the app, except if finalize the app in the taskmanager.

@Override
public void onCreate() {
    super.onCreate();

    Thread.setDefaultUncaughtExceptionHandler (new Thread.UncaughtExceptionHandler()
    {
        @Override
        public void uncaughtException (Thread thread, Throwable e)
        {
            handleUncaughtException (thread, e);
        }
    });

}

public void handleUncaughtException (Thread thread, Throwable exception)
{

    StringWriter _stackTrace = new StringWriter();
    exception.printStackTrace(new PrintWriter(_stackTrace));

    Intent _intent = new Intent();
    _intent.setAction ("com.mypackage.ERROR_ACTIVITY");
    _intent.setFlags (Intent.FLAG_ACTIVITY_NEW_TASK);
    _intent.putExtra("error", _stackTrace.toString());
    startActivity(_intent);

    System.exit(0);

}

I found out the solution. It's just add a Intent.FLAG_ACTIVITY_CLEAR_TASK like following:

@Override
public void onCreate() {
    super.onCreate();

    Thread.setDefaultUncaughtExceptionHandler (new Thread.UncaughtExceptionHandler()
    {
        @Override
        public void uncaughtException (Thread thread, Throwable e)
        {
            handleUncaughtException (thread, e);
        }
    });

}

public void handleUncaughtException (Thread thread, Throwable exception)
{

    StringWriter _stackTrace = new StringWriter();
    exception.printStackTrace(new PrintWriter(_stackTrace));

    Intent _intent = new Intent();
    _intent.setAction("br.com.magazineluiza.mobilevendas.ERROR_ACTIVITY");

    _intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); // Here is the solution

    _intent.putExtra("error", _stackTrace.toString());
    startActivity(_intent);

    System.exit(0); // or System.exit(1) It doesn't matter

}
