Changing activity in android clears the memory needed for the previous activities?

Question

I am developing a multi level game, where each level is a new activity.

I want to know, if i change the activity like

Intent myIntent = new Intent(ge         


        

Answer 1

You need to call finish() for the activity (or activities) that you no longer want to be active. You can simply call it right after starting the new activity:

Intent myIntent = new Intent(getBaseContext(), Level3.class);
startActivity(myIntent);
finish();

Otherwise, the previous activity will remain on the activity stack.
