Update activity from a second activity
<p>I need to update the score in one activity when an action is used in another activity. </p>

<p>In class 1 activity 1 - I have a score textview and this shows the score. The user then presses answer and this takes the user to another activity where they choose an answer from radio buttons. </p>

<p>In class 2 activity 2 - The user chooses an answer and the score in activity 1 gets updated if correct. </p>

<p>Is this possible?</p>

<p>Thanks. </p>
