Can't deploy the GeoQuiz example to a Galaxy S3


The DDMS Devices view shows my Samsung Galaxy S3 when I connect it. It shows what looks like the last 8 digits of a MAC address for the Name, then two question marks in the next column, and “unknown” in another column.

I’ve set up a Run Configuration that prompts for the device to deploy to. The Android Device Chooser dialog shows my S3 but when I select that radio button the OK button remains disabled.

What do I have to do go get ADT to deploy to my S3?
