If you simply want to test / run you app on Android then there’s no need to use Android studio at all. Simply do fuse build -tandroid -r from the commandline and it should autostart.
Just to add a little extra context. The Android Studio build are not supported yet. We have a compiler flag to create them (for the dangerious curious :p) but they are not what you want to use to make shippable apps right now.
I am working on Gradle support right now and we hope to have some announcements in that area once we have this completed and heavily tested. As you can imagine we were only able to start this transition once we could be sure that the NDK support (and other miscelaneous features) was stable.
I can’t give you a solid date but we all want this ASAP and you will definitely hear about it when the feature ships.
