Android sample: draw onto texture from TextureView in regular Activity

[netherpyro]

Hi! Thank you for the great lib. Could you please describe in general terms how can I change the Android sample to use TextureView inside Activity instead of NativeActivity to render on to?

I suppose you need to extract a native handle from the view and then you can create a Diligent texture using either IRenderDeviceGL::CreateTextureFromGLHandle or IRenderDeviceVk::CreateTextureFromVulkanImage depending on the API you are using.
