I'm having this problem with Huawei phones (P40, P40 pro, Mate 30 Pro). If I choose 1280x720 or 640x480 it will show a black preview and it will throw this exception:

I found that the problem is in the creation of `recorderSurface`, when it execute `createRecorder` and it set `setVideoSize` with the chosen resolutions it will throw the exception and shows a black preview. If I set `setVideoSize` with 1920x1080 resolution in the creation of `recourderSurface` and the chosen resolution in `recorder` it will be just fine but I don't know if it will crash in other devices different than huawei brand...I've tried in a xiaomi mi 9 se and it works fine.
