android bundleRelease does not sign the aab

Question

I've written an Android app, but the final step in the release process is still eluding me. I assume that when I run gradle bundleRelease it will generate the aab file I can upload in the play store. But the play store says the bundle is unsigned. However, the build process says it is signing:

> Task :app:preReleaseBuild UP-TO-DATE

There is a signing section in the gradle build script:

android {
    ...
    signingConfigs {
        release {
            storeFile file(...)
            storePassword '...' 
            keyAlias '...'
            keyPassword '...'
        }
    }

If I delete all aab files prior to running the build, an app.aab is generated in

..\app\build\outputs\bundle\release

Seems all in order, except the play store won't accept the aab:

The Android App Bundle was not signed.

How do I build a releasable aab?

If anyone is still looking for a solution - Set debuggable to false in release config. Your app build gradle file should have following -

buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
            signingConfig signingConfigs.release
            debuggable = false
        }
    }
