Android - Calling a method in one activity from another, without starting new activity

Question

I\'m developing an Android app using GreenDroid. The application is just for testing atm, so it all it contains is an ActionBar with a refresh button, three tabs, and an act

Answer 1

Right. If the method is static, which it probably should be if this is your goal, just call it like this:

YourClass.staticMethod(params);

If not, you'll need to create an object for it.

YourClass yourClass = new YourClass(constructorParams);
yourClass.method(params);

That should do it.
