Question

I’d like to set my newly created activity to be the only one on the stack and be on top of it as well, so when Activity B is created from A, I can press back to return to home menu from B.

Accordingly, this is what I did

public void onClick(View v) {
    Intent i = new Intent(this,B.class);

    i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
    startActivity(i);

}

For some reason, after Activity B starts, pressing back still takes me to A.

What am I missing here?

Answer 1

do like this

public void onClick(View v) {
Intent i = new Intent(this,B.class);

i.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
startActivity(i);
finish(); // to end the current activity
}

call finish() after startactivity(…), so that A activity ll removed from the stack. when you press back button A activity ll be not there in stack.
