Is this somehow possible? When I try to open a second camera (in another service) I'm getting an error. public class RecorderService extends Service implements SurfaceHolder.Callback { private WindowManager windowManager; private SurfaceView surfaceView; private Camera camera = null; private

Android M - MediaRecorder start failed

由 随声附和 提交于 2019-12-06 11:26:24
Samsung galaxy S6 edge 6.0.1 works fine, so maybe Android M is not the factor here. First off, the Android 6.0+ permissions are given, so that's not the case .
