I am using render texture to put on my raw image and show my mini map using this approach. But it was working correctly until I decided to use addressables in my project and then suddenly there was a bug. Raw image was rendering the texture correctly in the editor but in android a black screen was rendering instead of my render texture.

I solved the problem. When we are using addressables we have to know this point. I have Scene A and Scene B. My camera is on Scene A and has a render texture attached to its output. My Raw Image is on Scene B and has that render texture attached to its texture. If you have this situation then u will have the same problem because you have to put both of the camera and the raw image in the same scene.
