Hello! when I call startPreview on the onCreate method of an activity or a fragment, the surface becomes black (but my webcam turns on the led indicating it's on)
it only works when i call startPreview on a click of a button or something that will happen on a later time..
How can I fix that?

@rafaelcorreiapoli I had the same problem. The issue is your code calling startPreview before the surface is ready. Try adding callback to your surface and call startPreview in the onSurfaceChanged method.
