在你的onMessage中，确保你只是处理

GoogleCloudMessaging. MESSAGE_TYPE_MESSAGE.equals(messageType)

此外，由于两者都在调用generateNotification

，因此执行不正确

@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); }
