Question

接收GCM发送的消息时遇到了很多麻烦。我的WakefulBroadcastReceiver永远不会被解雇。我寻找了很多帮助，但没有用。任何帮助都将不胜感激！

WakefulBroadcastReceiver

public class GCMBroadcastReceiver extends WakefulBroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
        Log.e("TAG", "in BroadcastReceiver");
        ComponentName componentName = new ComponentName(context.getPackageName(), MyGcmListenerService.class.getName());
        intent.setComponent(componentName);
        startWakefulService(context, intent);
        setResultCode(Activity.RESULT_OK);
    }
}

IntentService

public class MyGcmListenerService extends IntentService {

    public static final String TAG = MyGcmListenerService.class.getSimpleName();

    public MyGcmListenerService() {
        super(TAG);
    }

    @Override
    protected void onHandleIntent(Intent intent) {
        Log.e("TAG", "in HandleIntent");
        Bundle extras = intent.getExtras();
        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(this);
        String messageType = gcm.getMessageType(intent);

        if (!extras.isEmpty()) {
            if (GoogleCloudMessaging.MESSAGE_TYPE_SEND_ERROR
                    .equals(messageType)) {
                Log.e("Send error: ", extras.toString());
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_DELETED
                    .equals(messageType)) {
                Log.e("Deleted messages: ",
                        extras.toString());
            } else if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE
                    .equals(messageType)) {
                for (int i=0; i<5; i++) {
                    Log.i(TAG, "Working... " + (i+1)
                            + "/5 @ " + SystemClock.elapsedRealtime());
                    try {
                        Thread.sleep(500);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
                Log.i(TAG, "Completed work @ " + SystemClock.elapsedRealtime());
                String msg = extras.getString("message");
                String urlImg = extras.getString("image");
                String title = extras.getString("title");
                Log.e("GCM Mesage: ", "msg: " + msg + " title: " + title);
                Toast.makeText(MyGcmListenerService.this, "msg: " + msg + " title: " + title, Toast.LENGTH_LONG).show();
            }
        }
        GCMBroadcastReceiver.completeWakefulIntent(intent);
    }
}

好的..所以有一些事情需要在这里修复。首先是扩展GcmListenerService（实际上它继承自IntentService，但为你完成剩下的工作），然后使用intent filter声明它

如果可能，请尽量使用Google提供的GcmReceiver，我认为它继承自WakefulBroadcastReceiver（https://developers.google.com/android/reference/com/google/android/gms/gcm/GcmReceiver）。

你可以找到我在https://github.com/ucsunil/android-gcm-practice/tree/master/android-gcm-chat处理的一个非常简单的样本 - 一个聊天应用程序（非常类似于我认为你试图做的但后来停止它。我记得通过日志和我请记住，它会正确接收消息，您可以使用它作为示例。我使用Gcm提供的服务和接收器。
