Android Service Starting A activity in its own process

Question

if Android service is running in its own process say "STACKPR", and this Service will starts a new activity, Will this activity is part of "STACKPR" process by default or its part of application process ?

I tried the below method, but it is starting in a application process.

// in on start
Intent sIntent = new Intent(this, BasicActivity.class);
sIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(sIntent);

If it is not part of Service process, How to starts a activity which runs in that Service process ?

Answer 1

By default ALL application components (Activities, Services, etc.) run in a single process.

The Intent.FLAG_ACTIVITY_NEW_TASK flag will create a new task stack for that Activity. Think of a new task stack as a separate entry when you press the Recents button. They are both in the same process though.

To have your Service, or any application component, run in a different process use android:process="<unique string>" . However, this is NOT recommended and you can usually accomplish the same outcome using a threading model.
