Memory leak

[migmacdev]

Hi I've been using the project for my own app,
I start the RajawaliVuforiaActivity from another activity, the problem is that every time I leave the RajawaliVuforiaAcivity, an instance of the renderer and the activity itself gets leaked.

So I test the RajawaliVuforia example and same thing.

Does anybody know how to solve this?

Here is a image from the android studio profiler and memory dump.
