Having an unsigned, non-debuggable build is very useful for profiling, but when I try and run the release variant of a small test APK, I get the following error in the event log:

10:19 AM Error running 'app': The apk for your currently selected variant (app-profile.apk) is not signed. Please specify a signing configuration for this variant (profile).

This doesn't make sense to me, since I've in the past been able to run non-debuggable apps without signing, so I try and create a 'profile' variant which copies all the default settings from 'debug', but just sets debuggable -> false. Same error.

For some reason, I can edit the 'debug' build type to run debuggable, but not any other build type.
