Answer 1

just working with Countdown timer

Schedule a countdown until a time in the future, with regular notifications on intervals along the way. Example of showing a 30 second countdown in a text field:

new CountdownTimer(30000, 1000) {

     public void onTick(long millisUntilFinished) {
         mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
     }

     public void onFinish() {
         mTextField.setText("done!");
     }
  }.start();

You should use AlarmManager or Timer service for doing it it is execute in every 3-5 second.

I have also make a function of using alarm manager auto logout if user ideal for 5 min then it is logout. public static void autoLogOut(Context context) {

    MyAlarmService.mContext = context;
    Intent myIntent = new Intent(context, MyAlarmService.class);
    pendingIntent = PendingIntent.getService(context, 0, myIntent, 0);

    AlarmManager alarmManager = (AlarmManager) context
            .getSystemService("alarm");

    Calendar calendar = Calendar.getInstance();
    calendar.setTimeInMillis(System.currentTimeMillis());
    calendar.add(Calendar.SECOND, (5 * 60));
    alarmManager.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(),
            pendingIntent);

    // Toast.makeText(context, "Start Alarm", Toast.LENGTH_LONG).show();
}

it is execute after if user ideal for 5 min.
