Usually this issue happen on updating android Studio V3.4 to V3.5. Try to delete debug/output.json and release/output.json files.

Then Try these steps:

Step 1: Clean Project(Build > Clean Project)

Answer 4

In my case build and launch project with different build configs was successful. But generating signed apk throws error Cause: buildOutput.apkData must not be null on the other hand apk was generated and Build Output toggle view prints BUILD SUCCESSFUL. Manual installation ends with message App not installed. My fault was using compileSdkVersion 'android-P' and after changing to compileSdkVersion 28 all goes well.

Answer 5

1- Delete all generated app bundles (.aab) and APKs for all variants.

2- Delete the build folder

3- clean project

Answer 6

Just change the Apk release/debug location.

EX:

/home/sanaebadi/Desktop

after change :

/home/sanaebadi/apk
