The test case I removed is invalid. The codename has had its int assigned, but the config claims it is not final. If this ever does need to be supported it's just a matter of making sure the Q -> 29 mapping (or whatever) in the finalized codenames map in android/api_levels.go. Test: treehugger Bug: http://b/154667674 Change-Id: I4f42ec2fd4a37750519ee3937938a1c65b6bb1e8
