Answer 1

Ok, i think the question is about how to free the memory that is being allocated using malloc() inside native code.

I had the same requirement in one of my Projects. I did it in the following way.

Inside onStop() or onDestroy(), I did a native call, which I have used to free() the allocated memory. This I think is the best and simplest way to do that. I am not sure if android is providing some API,s for this. It would be informatory to know if something like this exists. Thanks.
