Service that runs every minute

Question

I have a service that I am wanting to execute a task every minute in the background. It does not need to execute the task whenever the phone is asleep, only when the user is

Answer 1

This will send an intent to your service every minute without using any processor time in your activity in between

  Intent myIntent = new Intent(context, MyServiceReceiver.class);
  PendingIntent pendingIntent = PendingIntent.getBroadcast(context,  0, myIntent, 0);

  AlarmManager alarmManager = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
  Calendar calendar = Calendar.getInstance();
  calendar.setTimeInMillis(System.currentTimeMillis());
  calendar.add(Calendar.SECOND, 60); // first time
  long frequency= 60 * 1000; // in ms 
  alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), frequency, pendingIntent);           

Adjust MyServiceReceiver.class to match your target service or activity. The documentation provides more details to fine-tune your calls like whether you want exact timing, execution at a specific time of the day ...
