问题


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 Error

I've already tried to Clean & Make the Project and to Clean & Rebuild the Project, with no success.

I am using Android Gradle 3.5.0 & Gradle Version 5.4.1

This issue happens after update my Android studio v3.4 to v3.5 Now, it is working fine

I fixed this issue by deleting debug/output.json and release/output.json files
otherwise change your apk destination folder path.

Android Studio 3.5
compilesdkVersion 28

apk generating working



回答2:


option 1 - change the destination folder of the apk generated and generate apk again.

option 2 - delete the output.json file under release folder and generate apk again.

It solved my problem. I hope it will help you too.

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
