java – Why can't I generate a signed APK?

Posted by: admin June 15, 2020 Leave a comment

Questions:

I have an app, that works just the way I want it to and in the past I was able to generate signed APKs.
However now in my newest version (1.11) I can’t build a signed akp anymore. This thing gets shown to me:

Executing tasks: [:app:assembleRelease] in project C:\Users\Gereon\AndroidStudioProjects\Akkubuch
> Task :app:preBuild UP-TO-DATE
> Task :app:preReleaseBuild UP-TO-DATE
> Task :app:compileReleaseAidl NO-SOURCE
> Task :app:generateReleaseBuildConfig UP-TO-DATE
> Task :app:compileReleaseRenderscript NO-SOURCE

FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:lintVitalRelease'.
> Lint infrastructure error

How to&Answers:

OK just had the same issue. Thought I had Lint issues to resolve, but checking App> build > reports > lint-results-release-fatal showed a clean slate.

Tried to clean, but that did not work. So I ended up deleting the ‘build’ and ‘release’ folders. Somehow that worked. Don’t know what actually caused it.
