Question

我使用下面的代码使用GCM向客户端发送通知。下面的代码写在MainActivity.class中的onClickListener按钮上。通知已成功发送和接收。当我尝试阅读通知信息时，它没有任何

//发送通知代码//

String to = "To_sendor_id";
            Bundle data = new Bundle();
            data.putString("my_message", "Hello World");
            data.putString("my_action", "SAY_HELLO");
            String id = Integer.toString(Integer.parseInt("1"));
            try {
                gcm.send(to + "@gcm.googleapis.com", id, data);
            } catch (IOException e) {
                e.printStackTrace();
            }
            String msg = "Sent message";
            Log.d("Sent",msg);

//接收者代码

 public class SeriousBroadcastReceiver extends WakefulBroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
    try { String action = intent.getAction();
        Log.i("messages","action=" + action);
        if ("com.google.android.c2dm.intent.RECEIVE".equals(action)) {
            String payload = intent.getStringExtra("my_message");
            Log.i("messages", "payload=" + payload);
            String action = intent.getStringExtra("my_action");
            Log.i("messages", "action=" + action);
            Log.i("messages " , intent.getExtras().toString());}  finally {

    }
}

最后一次Log.i的输出：I / messages：Bundle [{message_type = send_event，event = sent，google.message_id = 1}]

尝试使用GcmListenerService代替WakefulBroadcastReceiver，如下所示：

public class EMSListenerService extends GcmListenerService {


    @Override
    public void onMessageReceived(String from, Bundle data) {
        super.onMessageReceived(from, data);

        String my_message = data.getString("my_message");
        String my_action = data.getString("my_action");

        //do something here

    }
}

不要忘记向menifest文件添加服务，如下所示：

<service
android:name=".services.EMSListenerService"
android:exported="false" >
 <intent-filter>
   <action android:name="com.google.android.c2dm.intent.RECEIVE" />
 </intent-filter>
</service>

GCM中没有数据已收到通知
