Black TextureView after navigation

[ghost]

I use a BottomNavigationView to navigate between my camera fragment and another one.
On the start of my app the camera preview is loaded correctly.
If I navigate to my second fragment and back again, CameraX is successfully bound to the lifecycle, but the TextureView is black.

I can resolve this by adding Thread.sleep(330) before CameraX.bindToLifecycle() but this is a bad solution, because it adds some delay before showing the preview.

What can I do to solve this problem without this delay?

Can you please provide some code that lets us reproduce this issue?

I think, its happen when u rebind camera to lifecycle.
I have black screen os some devices (ex. Alcatel 5059D) when trying to switch between front and back cameras.
I have error in logcat:
E/Camera: CameraDevice.onError(): 1 with error: ERROR_MAX_CAMERAS_IN_USE

I think this issue should be at least partially alleviated with alpha04. Please reopen if it still reproduces, and provide specific device and code to reproduce this issue consistently.
