Fixed an issue with Android Custom Camera Preview conflicting with other native objects

Just a heads up to anybody who’s been using our https://marketplace.coronalabs.com/corona-plugins/android-custom-camera-preview plugin, that there was a bug causing everything on the OpenGL layer to be removed when calling the stop() method, instead of just the elements created by the plugin itself. This meant that native.* objects would vanish after using the camera - sorry!

This is now fixed and already synchronised to the Corona build servers, so new builds should just magically work properly without any changes within your own code.
