After I\'ve updated Android Studio 3.4 to 3.5 and wanted to build a Signed APK, however I get the error :
Cause: buildOutput.apkData must not be null Erro
It's working on AS 3.4.2 version. I've tried everything (Clean & Make the Project and to Clean & Rebuild) and downgraded to 3.4.2 at last.
This issue might be fixed in the 3.6 release. https://androidstudio.googleblog.com/2019/07/android-studio-36-canary-5-available.html
