Returning to the proper activity when pressing the BACK button?

I'm creating an app with multiple screens the user will have to navigate through. Specifically, I'm currently working on a set of activities that must link together as follows:

So to simplify, I want it like this.

I tried doing this:

@Override
public void onBackPressed() {
    super.onBackPressed();
    Intent intent = new Intent(this, MainActivity.class);
    startActivity(intent);
    finish();
}

But this just invokes a new instance of MainActivity. When I then press BACK at that MainActivity instance, it takes me back to CharacterMainActivity.

How can I achieve this? I'm assuming it involves accessing the Activity stack?

You can start the child activities for result and then finish the child activities with the result also with the same request code.

To start the child activity:

startActivityForResult (Intent intent, int requestCode)

for finish all the child activity

finishActivity (int requestCode)

When you move from Activity B to Activity C, call finish() at the same time you call startActivity on Activity C. This will remove Activity B from the task stack.
