I was able to use the standard "ProgressDialog" for Android to show that an undefined task was running. 
But I would like to use the "smaller" spinner progress dialog, which was used for undefined tasks in some standard Android applications, such as the Android market (there is a small spinning circle that is actually integrated into the application window (on the contrary, it floats on top of it ) 
Does anyone know how to create a little dialogue of progress (or can someone point me in the right direction)?
