Call a activity's function from the other

I have two activities A and B. Activity A starts activity B. Now I'm in B, how to call A's function?

Well, you can't...but what you can do is this:

  1. You can create a BaseActivity with the functionality you want in both A and B, and then have both A and B extend this class.
  2. You can pull the common code into its own class, and have it be a member variable on both A and B.

The first way is probably preferred, as it may be difficult to get your common code class into the activities.

Unless function is static you are out of luck. I suggest that you place necessary functions in Application object or make them static.

Note that activity not on top of the stack can be destroyed at any time.
