GCM 3.0 - gcm 不会自动显示带有通知参数的通知

Question

新的 GCM 3.0 应该允许 GCM 自动显示从服务器发送的通知，如果它们包含 notification 参数。

如docs中所述：

The notification parameter with predefined options indicates that GCM will display the message on the client app’s behalf if the client app implements GCMListenerService on Android

然而，即使实施了 GCMListenerService，我也很难让它工作。

AndroidManifest.xml

    <receiver
        android:name="com.google.android.gms.gcm.GcmReceiver"
        android:exported="true"
        android:permission="com.google.android.c2dm.permission.SEND" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
            <category android:name="cz.kubaspatny.pushservertest" />
        </intent-filter>
    </receiver>

    <service
        android:name="cz.kubaspatny.pushservertest.gcm.CustomGcmListenerService"
        android:exported="false" >
        <intent-filter>
            <action android:name="com.google.android.c2dm.intent.RECEIVE" />
        </intent-filter>
    </service>

CustomGcmListenerService.java

public class CustomGcmListenerService extends GcmListenerService {

    @Override
    public void onMessageReceived(String from, Bundle extras) {
        super.onMessageReceived(from, extras);
        Log.d("GcmListenerService", "Received gcm from " + from + " with bundle " + extras.toString());
    }
}

来自服务器的通知已记录但未由 GCM 显示。

Received gcm from 333813590000 with bundle Bundle[{notification={"icon":"ic_launcher.png","body":"great match!","title":"Portugal vs. Denmark"}, collapse_key=do_not_collapse}]

从服务器发送的消息：

{       
      "registration_ids":[...],
      "data": {
        "notification" : {
            "body" : "great match!",
            "icon" : "ic_launcher.png",
            "title" : "Portugal vs. Denmark"
          }
      } 
}

是否需要执行其他操作才能自动显示？

Answer 1

尝试使通知字段成为数据字段的同级字段。数据字段传递给onMessageReceived，通知字段用于自动生成通知。

{       
      "registration_ids":[...],
      "notification" : {
            "body" : "great match!",
            "icon" : "ic_launcher.png",
            "title" : "Portugal vs. Denmark"
      }

}
