i basically want to call my home page activity with a alert box when given time period will expire (Time calculation done by timer service), it does not matter which activity is the current activity when time session will expire if session expired the execution should redirected to home page with a alert box. — user9106826, Apr 08 '18 at 08:45

You can open the activity in onFinish() with creating new Intent:

Intent intent = new Intent(textView.getContext(), ActivityA.class);                      
startActivity(intent);

To initiate the service, you can call:

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

To start a service to perform a one-time operation by passing an Intent to startService().

intent dialogIntent = new Intent(this, MyActivity.class);
dialogIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(dialogIntent);

try this.
