Clear memory #34

Hello, I tried the demo that you provide and I notice that any time a fragment changed the memory of the old map didn't free even when I use the destroy method. Can you give me some feedback.

Hello, that's because this demo keeps into the back stack each and every navigated fragment. If you pop the back stack before navigating to a new fragment (using navController.popBackStack()), and if you perform a manual GC into the profiler, you'll see that the previously allocated memory is freed. I should probably update the demo, because keeping previous fragments into the back stack isn't that helpful.

I think it will work, thank you
