Killing one activity from another

I have two activities A and B. B is a transparent pass through activity, and A is seen. I want to kill B by pressing a button A.

Here\'s what I\'ve tried so far:

Answer 1

I found a nice way to finish one activity from another, it is similar to what Lumis did. So if you want to close ActivityA from ActivityB you can do this:

In ActivityA do:

className = this.getClass().getName();

and pass it on to AvtivityB. Then in ActivityB do:

((Activity) Class.forName(className).newInstance()).finish();

You can put a string with the name of your class into className yourself, but it needs to be a full name with package too.
