Public Methods
public CameraSourceConfig.Builder
setRequestedPreviewSize (int width, int height)
Sets the desired width and height of the camera frames in pixels. If the exact
desired values are not available options, the best matching available options are
selected.
We pass the desired size to CameraX and let CameraX choose the best available
size.
Default: 480x360.
