NullPointerException whn closing an Activity from another Activity

I have Activity A that starts another Activity B.

When I am in Activity B I should be able to close both A and B.

For this purpose I used the approach at this link https://stackoverflow.com/a/11509279/1815311, but sometimes I get a NullPointerException when I do aActivity.handleToClose.finish();

Please what possibly can be wrong here???

That happens because your Activity A is closed form some reason and when you call you method to close that activity you get null pointer exception.

The solution is to check if Activity A is finished or not, if it is finished than you dont need to call finish
