Android regular task (cronjob equivalent)

I am currently trying following code to perform a task on daily basis

public class BackupService extends Service {

    private Timer timer = new Timer();
    @Override
    public IBinder onBind(Intent arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Toast.makeText(this, "Service Started", Toast.LENGTH_SHORT).show();
        startBackup();
        return START_STICKY;
    }

    private void startBackup() {

        Date date = new Date(time);
        System.out.println("Backup time:" +date);
        timer.scheduleAtFixedRate(new BackupTimerTask(), date,
                delayTime());
    }

    private long delayTime() {

        long delay = 86400000;
            System.out.println("delay time:" + delay);
        return delay;
    }

    @Override
    public void onDestroy() {
        // TODO Auto-generated method stub
        super.onDestroy();
        if (timer != null){
            timer.cancel();
            }
            Toast.makeText(this, "Service Destroyed", Toast.LENGTH_SHORT).show();
    }

  private class BackupTimerTask extends TimerTask {
        @Override
        public void run() {
            System.out.println("Backup started");
            //starting backup here
        }

    }

}

and I am calling this service as

startService(new Intent(this, BackupService.class));

This is working fine if I put short interval like 5 minute, but this is not working on long inteval. And if I go to running services in android apps then i can see my service is in running state. I think probably something is wrong with timertask class. How I can solve my problem??

Answer 1

Milos makes some good points, but please don’t make your service a Foreground service. Instead, use AlarmManager. There are several related issues that you can take a look at:

Android AlarmManager – Scheduling a recurring Intent to fire off twice a day

AlarmManager not working

etc…
