Question

I have two activities A and B. I need to start a service from A. The service will do some actions. I need to use some data from the service in activity B. How can I do this.
Please explain this with a sample code.

Answer 1

You may send data via intent in StartService method.

This code from my service (StartService method)

Intent updater = new Intent();
updater.setAction(AppWidgetManager.ACTION_APPWIDGET_UPDATE);
updater.putExtra("betHour", pref.getInt("Hr", exampleHour));
updater.putExtra("betMin", pref.getInt("Mn", exampleMinute));
PendingIntent pen = 
    PendingIntent.getBroadcast(getApplicationContext(), 0, updater, PendingIntent.FLAG_UPDATE_CURRENT);

AlarmManager alarmManager = 
    (AlarmManager) getApplicationContext().getSystemService(Context.ALARM_SERVICE);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME, SystemClock.elapsedRealtime() + 1000, 60000, pen);
