Managing screen flow
<p>To keep it simple I have 3 screens. A, B and C.
You can access Screen B or C from screen A.
You can access Screen C from screen B
You can access Screen B from screen C</p>

<p>Data from screen A is passed to B and C</p>

<p>What I am looking to do is create a button on screen B and C and where ever they are takes it back to screen A. I do not want to start a new activity of A as it requires the data it created</p>

<p>Also is there a way to overrule what the back button on the phone does. ie if on screen C it goes back to A even is the user clicked B and then C?</p>

<p>Thanks for your time</p>
