Start by reproducing tns debug android --log trace with the provided NativeScript SDK examples package and compare it with tns doctor --log trace, which reportedly locks during system information collection. The issue names no source file or test; done means identifying and fixing the cause so the Android app starts under debug and the command no longer hangs.
