停止GcmListenerService编程

Question

I am using GCM. I want to stop GcmListenerService so I can stop Application from receiving unwanted notification.

I have tried the below to close the service but it doesn't seems to workout

Intent intent = new Intent(this, MyGcmListenerService.class);
stopService(intent);

Here is my service class

public class MyGcmListenerService extends GcmListenerService
{

    private static final String TAG = "MyGcmListenerService";

    // [START receive_message]
    @Override
    public void onMessageReceived(String from, Bundle data) {
        String message = data.getString("message");
        String duration = data.getString("duration");
        Log.d(TAG, "From: " + from);
        Log.d(TAG, "Message: " + message);

        sendNotification(message,duration);
    }
    // [END receive_message]

    private void sendNotification(String message, String duration) {

        new DisplayNotification(this).makeGCMNotification("Event Name", "Event Start Time", 1);
    }
}

and in manifest

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

Answer 1

Stopping the service won't help because the GCMReceiver will always call startWakefulService whenever a new message comes in. Since the GCMReceiver class is not really something we're supposed to edit, I suggest that you keep a boolean or set a preference to know when received messages should actually be read/processed. Based on this, you can let the messages get received in the background while actually doing nothing in the app/foreground.

You can unsubscribe from GCM with two methods: deleteToken() and deleteInstanceID() . Both approaches generate IOExceptions so they must be handled as well.

Please look at the "Unregistration and Unsubscription" section .
