Saving numbers in activity to use again later
<p>In the last activity of my app there is some numbers displayed in edit text's and an option to add more to these totals, the add more button takes you back to start of the app, where the user does the same thing again inputs some numbers and ends up back on last activity.</p>

<p>What I want to do is if they press the add more button is save the numbers that are in the edit text's so I can add them to the new set of numbers coming in. </p>

<p>What I thinking is save the numbers in on Pause, but don't know how and then add them to new numbers in on Resume, am I on the right track, what is the best way to do this.</p>
