Android Studio 2.2 - Can No Longer Create Unsigned Release Builds - "validatesigningreleaselive Failed"

After upgrading to Android Studio 2.2, I can no longer create an unsigned release build. Debug builds are created fine. This problem didn't happen on Android Studio 2.1. I can't fi

Solution 1:

I eventually figured it out: Remove all 3 lines of "signingConfig signingConfigs.noSigning", where "noSigning" was defined as:

signingConfigs {
    noSigning {
        keyAlias ''
        keyPassword ''
        storePassword ''
        storeFile null
    }
    defaultSigning {
        storeFile file('signing/signing.keystore')
        storePassword 'password'
        keyAlias 'alias'
        keyPassword 'password'
    }
}

Those "noSigning" lines do not seem to work on Android Studio 2.2. I guess they are non-standard anyway, because the 'assembleRelease' task will create an unsigned build by default anyway.
