Question

我在互联网上搜索了答案，但没有找到它们。所以我签署我的apk把它放在商店，作为更新。当我在我的设备上启动应用程序时，屏幕变黑。有任何想法吗？

        if ( e!=null )
            MainShip.getInstance().log_message(Log.getStackTraceString(e), true);   
    }

}

// This is the callback for when your async task has finished
@Override
public void onTaskFinished() {      
    completeSplash();
}

private void completeSplash(){
    startApp();
    finish(); // Don't forget to finish this Splash Activity so the user can't return to it!
}

private void startApp() {
    Intent intent = new Intent(SplashScreen.this, MainScreen.class);
    startActivity(intent);

}

@Override
public void onBackPressed() {
    return;
}

}
