                // During wake up the activity should be translucent to allow the application

                // underneath to start drawing. Normally, the WM animation system takes care of

                // this, but here we give the dream application some time to perform a custom exit

                // animation. If it uses a view animation, the WM doesn't know about it and can't

                // make the activity translucent in the normal way. Therefore, here we ensure that

                // the activity is translucent during wake up regardless of what animation is used

                // in onWakeUp().

                mActivity.convertToTranslucent(null, null);

            // As a minor optimization, invoke the callback first in case it simply

            // calls finish() immediately so there wouldn't be much point in telling

            // the system that we are finishing the dream gently.
