That makes no sense to me, sorry. Most of the time, you only need one
or the other, not both. Why do you think you need both in this case?

The code you originally posted assumes that bindService() is
synchronous. It is not. Do not attempt to use dssShow two statements
after bindService(). Do not reference dssShow until
onServiceConnected() is called.
