Question

我的应用程序正常运行，但我遇到以下错误：

10-04 14:04:38.182: W/MessageQueue(8625): Handler (android.media.MediaPlayer$EventHandler){416ad6b0} sending message to a Handler on a dead thread
10-04 14:04:38.182: W/MessageQueue(8625): java.lang.RuntimeException: Handler (android.media.MediaPlayer$EventHandler) {416ad6b0} sending message to a Handler on a dead thread

10-04 14:04:38.182: V/MediaPlayer(8625): back from callback

我已经看到this thread和建议的解决方法，但它对我不起作用。

有人有另一种解决方案吗？

Answer 1

 // create a handler to post messages to the main thread
 Handler mHandler = new Handler(getMainLooper());
 mHandler.post(new Runnable() {
     @Override
    public void run() {
        Toast.makeText(getApplicationContext(), "hello", Toast.LENGTH_SHORT).show();
    }
 });

尝试此代码希望它有所帮助

Answer 2

您可以在GCM示例应用中使用Handler而不是在GCMIntentService中使用BroadcastReceiver，而不是在此答案中建议：Update TextView from GCMIntentService in Methods onRegistered and onUnregistered

GCMIntentService +在死线程上向Handler发送消息
