音樂播放器播放MP3連續兩次從音樂播放器在後臺 但音樂播放器的幫助原始文件夾

Question

即時播放MP3的時候是打兩次

我我解釋說，我在做什麼..im recieving在後臺推送從服務器 通知和播放MP3從原材料使用音樂播放器

我的問題是，我的MP3是在一個時間

這裏打兩次是我的代碼

在你的onMessage，請確保您只處理

GoogleCloudMessaging. MESSAGE_TYPE_MESSAGE.equals(messageType)

此外，不正確履行既呼籲generateNotification

@Override protected void onMessage(Context context, Intent intent) { Log.i(TAG, "Received message"); String message = intent.getExtras().getString("price"); displayMessage(context, message); // notifies user generateNotification(context, message); } /** * Method called on receiving a deleted message * */ @Override protected void onDeletedMessages(Context context, int total) { Log.i(TAG, "Received deleted messages notification"); String message = getString(R.string.gcm_deleted, total); displayMessage(context, message); // notifies user generateNotification(context, message); }
