Android: how to run AsyncTask at regular interval in background service

问题

How do I run an AsyncTask at regular interval of 2 mins sleep for 10 times in the background service?

As VM stops my service at any time, my AsyncTask is also getting closed.

I have tried ScheduledThreadPoolExecutor, Timer, TimerTask all gets stopped once Service gets stopped.

Is there a good option start with?

Any help is appreciated.

Your service will never get stopped but you should show notification. Try implementing foreground service. foreground service

Foreground service displays notification and is never stopped.

Implement this code snippet in your service

Notification notification = new Notification(R.drawable.icon, getText(R.string.ticker_text),
        System.currentTimeMillis());
Intent notificationIntent = new Intent(this, ExampleActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);
notification.setLatestEventInfo(this, getText(R.string.notification_title),
        getText(R.string.notification_message), pendingIntent);
startForeground(ONGOING_NOTIFICATION_ID, notification);
