呼叫AsyncTask的推送通知时出现 [英] Call Asynctask when a push notification appears

问题描述

我的要求是，当一个推送通知进来我的设备，我需要调用一个AsyncTask的。应用程序可以在后台运行。我不应该单击该通知，而不是当谈到我需要调用的AsyncTask。这可能吗？

My requirement is when a push notification comes in my device, I need to call an Asynctask. The app can be running in background. I shouldn't click the notification, instead when it comes I need to call Asynctask. Is that possible?

推荐答案

在您的GCMIntentService只是覆盖的onMessage（..）方法时，推送通知在正在添加的设备调用此方法。

In your GCMIntentService just override onMessage(..) method this method called when push notification is comming in device.

   @Override
    protected void onMessage(Context context, Intent intent) {

        mContext = context;

        final String message = intent.getStringExtra("message");
        Log.e(TAG, "GCM Received message : "+message);


    AsyncTask<Void, Void, Void> DatabaseOperationTask = new AsyncTask<Void, Void, Void>() {

            @Override
            protected Void doInBackground(Void... params) {

                // do your Database Operation here

                return null;
            }

            @Override
            protected void onPostExecute(Void result) {

                super.onPostExecute(result);

            }
        };
        DatabaseOperationTask.execute();

    }
