[BUG] Endless request for permission to use the camera

BUG

My team and I discovered a bug when an application requests permission to use the camera and we forbid it, it endlessly repeats asking for permission.

The bug is reproduced only in android devices. Except Android version 12 (everything works fine here).

Solution

When we click on the "Deny" button, the onResume function is called again. It in turn re-checks the permission. This can be seen in the screenshot below. (link to the code: line 55)

In order for everything to function properly, we have removed this part of the code. #603

We are waiting for a corrected new version of the package from the contributors! @juliansteenbakker @juliuscanute Pull request: #603
