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.

Answer 2

The solution :-

1- Build -> Clean Project didn't help

2-Build -> Make Project didn't help

3- restart android studio didn't help

4- Manually remove Build folder from app and project didn't help

the only solution for me was to remove all old builds from destination folder

Answer 3

I was getting this error also, when trying to "Generate Signed APK" for my release version. I tried all of the above methods, unfortunately none worked for me.

What worked, was generating first the debug signed version of the app, and then generating again the release one.

I do not know what exactly changed or what the original problem was, but it worked. I hope it will help you too, because this error is quite annoying...

Answer 4

All the solutions didn't work with me
In my case from AndroidStudio 3.4+ update to 3.5.
And finally I solve it by modify 'Destination Folder' to "app/build/outputs/apk"
