Rajawali transparent background of "RajawaliTextureView" (Augmented Reality)

Question

I want to display a "RajawaliTextureView" over a Camera2 API preview (also TextureView), but the the background isn't transparent. The result is a black background and I can't see the camera preview.

How can I make a transparent background of the RajawaliTextureView?

Answer 1

This is not possible with a TextureView. Even if you render a transparent clear color, it will be against a white background because of how Android uses texture views in its drawing system.
