Android Activity or Service for mathematical calculations?
<p>I'm creating a simple tip calculator to get into Android programming. I have created the main activity but I have a question. Should I do the actual calculations in the Activity, or should I have another service class that I bind the activity to that does the calculations for total and splitting and sub total, etc? Is there an advantage to doing the calculations in the service and passing the results back to the activity? Is that how it should be done?</p>

<p>I'm used to the whole MVC setup it seems with Android the Activity is the view and controller</p>
