I've been fighting with this problem, too. It persists in 3.7. The double-click doesn't happen on my Android tablets (4.1), just Android phones (2.3 and 4.1).
It's pretty bad, because I am using dojox mobile Views. So, for example, when you select a basemap in the basemap gallery, the second event might fire right on the map zoom button, or show a popup infoWindow on the map!
Any progress on a fix for this?
