I'm a new android application engineer. I'm trying to make a vulkan rendering backend demo which use SurfaceView as a View on android Java code. I made the gles rendering backend demo using GLSurfaceView as well. On application code, I use setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) API set activity from default portrait to landscape. But it doesn't work on SurfaceView while it works on GLSurfaceView.
I use renderdoc capture the rendering result, the image is in landscape layout(the same layout as gles backend). I doubt it was's something wrong with some settings on activity or window, but can't figure it out the root cause. Could somebody help what maybe the problem is?
Here is the Java source code.
