Bug at CameraXBasic example : camera switch

See original GitHub issue

When calling bindCameraUseCases at camera_switch_button click listener, it doesn’t work correctly with Galaxy S10+, Note 8

If I add CameraX.unbindAll() code to bindCameraUseCases() function at start line, it works normarlly.

private fun bindCameraUseCases() {
        CameraX.unbindAll()
        ...
}

OK, the problem is that when the camera switch button is pressed, we are trying to bind all camera use cases without unbinding the previous ones first. Thanks for flagging!

I think that the proper solution here would be to call CameraX.unbindAll() inside of the switch button callback, rather than inside of the bindCameraUseCases() function.

@owahltinez Yes. When I press the switch button, 100%. - Galaxy S10+ confirmed

In logcat, error occurred just one time with this message

2019-07-18 20:24:29.535 4188-4239/com.android.example.cameraxbasic E/Camera: CameraDevice.onError(): 1 with error: ERROR_MAX_CAMERAS_IN_USE

After this, error message doesn’t shown and only this message has logged when press switch button.

And if I add CameraX.unbindAll() to bindCameraUseCases() function, it works properly without any error message
