从android中的GCM Intent Service无休止地获取通知

我创建了一个活动,当通知发生时刷新但我面临一个问题,即当收到通知时,它会继续发送无尽的相同通知。早些时候它工作正常,但我做了一些改变,这已经做了。请帮我。我正在附上我的代码。

GCM IntentService类的代码

         @Override
protected void onHandleIntent(Intent intent) {
    Bundle extras = intent.getExtras();
    String msgg = intent.getStringExtra("message");

     final ResultReceiver receiver = intent.getParcelableExtra("receiver");
    Bundle bundle = new Bundle();
    if (!extras.isEmpty()) {

        if (GoogleCloudMessaging.
                MESSAGE_TYPE_SEND_ERROR.equals(messageType)) {

            sendNotification(this, msgg);


        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_DELETED.equals(messageType)) {

            sendNotification(this, msg);
            updateMyActivity(this,msgg);
            bundle.putString("result", msg);
            receiver.send(STATUS_FINISHED, bundle);

        } else if (GoogleCloudMessaging.
                MESSAGE_TYPE_MESSAGE.equals(messageType)) {
            updateMyActivity(this,msgg);
            sendNotification(this, msg);



        }


}

发送通知代码

 private void sendNotification(Context context, String message) {

    Intent resultIntent;

    int icon = R.mipmap.ic_launcher;
    long when = System.currentTimeMillis();
    NotificationCompat.Builder nBuilder;
    Uri alarmSound = RingtoneManager
            .getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);


    NotificationCompat.BigPictureStyle notiStyle = new
            NotificationCompat.BigPictureStyle();
    notiStyle.setBigContentTitle("afewtaps");
    notiStyle.setSummaryText(message);


    nBuilder = new NotificationCompat.Builder(context)
            .setSmallIcon(icon)
            .setContentTitle("afewtaps")
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message))
            .setLights(Color.BLUE, 500, 500).setContentText(message)
            .setAutoCancel(true).setTicker("Notification from afewtaps")
            .setSound(alarmSound);



    resultIntent = new Intent(context,
            LoginActivity.class);
    resultIntent.putExtra("message", message);

    resultIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);


    PendingIntent resultPendingIntent = PendingIntent.getActivity(context,
            notify_no, resultIntent, PendingIntent.FLAG_UPDATE_CURRENT);
    // Show the max number of notifications here
    if (notify_no < 9) {
        notify_no = notify_no + 1;
    } else {
        notify_no = 0;
    }
    nBuilder.setContentIntent(resultPendingIntent);

    NotificationManager nNotifyMgr = (NotificationManager) context
            .getSystemService(context.NOTIFICATION_SERVICE);



    nNotifyMgr.notify(notify_no + 2, nBuilder.build());


}

向广播发送消息

    // This function will create an intent. This intent must take as parameter the "unique_name" that you registered your activity with
static void updateMyActivity(Context context, String message) {

    Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

    //put whatever data you want to send, if any
    intent.putExtra("message", message);

    //send broadcast
    context.sendBroadcast(intent);
}

这结束了意图类的代码。

现在我的活动代码

         @Override
public void onResume() {
    super.onResume();
   // connectToDatabase();
    getActivity().registerReceiver(mMessageReceiver, new IntentFilter("com.google.android.c2dm.intent.RECEIVE"));
}

//Must unregister onPause()
@Override
public void onPause() {
    super.onPause();
    getActivity().unregisterReceiver(mMessageReceiver);
}


//This is the handler that will manager to process the broadcast intent
private BroadcastReceiver mMessageReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {

        // Extract data included in the Intent
        String message = intent.getStringExtra("message");

        //do other stuff here

        connectToDatabase();


    }
};

好。所以你的代码发生的是你正在向你的Receiver发送一个广播,并强制再次调用onHandleIntent,结果调用updateActivity方法,再次广播并循环继续。

updateMyActivity方法中,请更改此内容:

Intent intent = new Intent("com.google.android.c2dm.intent.RECEIVE");

Intent intent = new Intent("myMessage");

这里的罪魁祸首是

com.google.android.c2dm.intent.RECEIVE

在广播时调用onHandleIntent。

此外,在您的onResume活动方法中,请将标签更改为myMessage

getActivity().registerReceiver(mMessageReceiver, new IntentFilter("myMessage"))
