sp mCamera is a member variable of Camera,

sp c = new Camera(cameraId);

sp cl = c;

cl and c->mCamera as pass parameters

c->mCamera parameter passed to ICameraService converted to sp

The first one, cl=c, why can it be converted?

Second, why can mCamera be converted to sp?

Is it because of SP?
