onBackPressed() should call previous activity's onBackPressed()

Question

So here is the problem, I perform A → B and from B I do B → C , now when the back button is pressed in C I want to go back to A. so at start the flow is A → B → C but I want to clear B when I start C so when back pressed from C I go back to A. I know I can start A from C and CLEAR_TOP but I am looking for another alternative if there is one.

Thank You

What about calling `finish()` in `Activity` B when going to `Activity` C? Of course call `finish()` after `startActivity`. — R. Zagórski, Nov 22 '16 at 11:55
For confirming I have to Ask this A,B and C are fragments in same activity ? — Nithinlal, Nov 22 '16 at 11:55
call finish() method inside of B activity. you can call finish() below startActivity(intent) method. — Vishal Chhodwani, Nov 22 '16 at 11:57

You just need to call finish()

Intent intent = new Intent(this, NextActivity.class);
startActivity(intent);
finish();

    //FROM A TO B
    Intent A = new Intent(A.this,B.class);
    startActivity(A);

    //FROM B TO C
    Intent B = new Intent(B.this,C.class);
    startActivity(B);
    finish();

    //FROM C TO A
    onBackPressed(); you can go directly to A.

hope this may help u.

Intent intent = new Intent(this, C.class);
startActivity(intent);
finish();

If you call finish() after start C Activity, in B Activity. You can remove B Activity from stack. So if you press back in C, you will see A Activity.
