Hi, I'm trying to record a video on android right now, when I run my code (the whole code above), the camera can't be initialized. I guess I have an error in the following part.
private boolean initCamera() { try { camera = Camera.open(); Camera.Parameters camParams = camera.getParameters(); camera.lock(); holder = videoView.getHolder(); holder.addCallback(this); holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); } catch(RuntimeException re) { Log.v(TAG, "Could not initialize the Camera"); re.printStackTrace(); return false; } return true; } holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); this line in this code gets multiple markers, saying
- The method
setType(int)from the type SurfaceHolder is deprecated - The field
SURFACE_TYPE_PUSH_BUFFERSis deprecated
Does anyone know the reason why I'm getting this?
