how to restart main activity while retaining some data
<p>This is my first app and I'm trying to write a simple Liar's Dice game. </p>

<p>I wrote everything in the main activity class, rolls random dice, textedit boxes to enter bids and buttons to bid and call. </p>

<p>So after the game runs, how do I get it to keep track of the score and run again? </p>

<p>I've tried making another activity screen with a restart button and have it go there after the game ends so I can restart the main activity. However I am able to press back(phonekey) from that screen and get stuck at the end of the previous game. </p>

<p>Also I am trying to use an array to keep track of the wins and losses but not sure how to go about bringing it back and forth from the activities.</p>
