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

Updating to Android Studio 3.4.?, i get the message

Cause: buildOutput.apkData must not be null

looking for an answer i found the procedure:

Build -> Clean Project

but it doesn´t worked, i know that this procedure will delete the content into the /build directory but for my experience it doesn´t work in all cases, so i tried the "raw" way, deleting the directory:

/app/build/ 

then i rebuild the project and it worked.
