Cause: buildOutput.apkData must not be null

Question

My android application using Kotlin is throwing this exception when I try to Run \'app\' in the emulator o in my cellphone. When I build my project it runs well, with no err

Answer 1

AS 4.0.1 (installed via snap)

Ubuntu 18.04 lts

configuring builds via build variant.

Combinations of invalidate cache / build / clean etc didnt help on their own, the only thing that helped was to switch build the active build variant back to armDebug and clean / rebuild after that.

Once I switched back to the desired variant I could build correctly.
