Your Android App Bundle is signed with the wrong key. Ensure that your app bundle is signed with the correct signing key and try again

Question

How do I sign my android app bundle with the correct signing key?

Answer 1

I had the same error when building a signed Android App Bundle.
For debug purposes on the local maschine, I enabled debuggable in the release build type.
It seems, Playstore recognized an debug build and simply said it is not a valid Bundle.

build.gradle:

buildTypes {
     release {
         minifyEnabled true
         proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
         //debuggable = true  <----- Works like expected when disabled
     }
}
