title: implement Canvas in non-Activity class in Android
body: <p>I am working on a project that extends the Map Activity class once.This project can only have this one activity.</p>
  
  <p>I would like to implement the Canvas however since from my knowledge it depends on the Activity class, this has proven to be a road block.</p>
  
  <p>My query is how can I bypass this issue? <strong><em>Is there a way I can actually draw on a canvas minus the Activity class?</em></strong> Any ideas would be gladly welcome. Thanks</p>
