Answer 1

Create an action that can be an abstract class extending the Activity . Now every new Activity needs to extend this class. For instance:

 //Your base class, where you can have your Action bar and other the other methods which you want all your other classes to inherit public abstract class AbstractActivity extends Activity{} // You all other classes public class FirstActivity extends AbstractActivity{} public class SecondActivity extends AbstractActivity{} 

See android how to create your own activity and expand its question

Hope this helps.

Yes it is possible.

You just need to expand the main activity in other actions.
