Question

My Android application consists of many activities, each of which represent a menu:

• Activity A (the main Activity & first level menu)
• Activity B (second level menu)
• Activity C (third and last menu)

I am monitoring the user’s action in a service. When an event (detected by service) occurs, I want to close all of Activities and restart Activity A. The code I wrote below only works in an Activity, not a Service:

Intent myIntent = new Intent();
myIntent.setClassName("main.activity", "ActivityA");
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
                  Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(myIntent);

How can I do this in a Service?

What about this:

Intent myIntent = new Intent();
myIntent.setClassName("main.activity", "ActivityA");
myIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP|
              Intent.FLAG_ACTIVITY_SINGLE_TOP|
              Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(myIntent);
