This is the navigation of my application:
Activity1 calls Activity2 → Activity2.finish(), call Activ
Activity1
Activity2
Activity2.finish()
Activ
Also there is other technique, you can call startActivity(new Intent(getApplicationContext(),Activity1.class)) method along with the Bundle class to transfer data from activity3 to activity1.
startActivity(new Intent(getApplicationContext(),Activity1.class))
