build.gradle

android {
    // ....
    applicationVariants.all { variant ->
        renameApk(variant, defaultConfig)
    }
}

// ---------------------------

def renameApk(variant, defaultConfig) {
    variant.outputs.each { output ->
        if (output.zipAlign) {
            def file = output.outputFile
            def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + ".apk")
            output.outputFile = new File(file.parent, fileName)
        }
        def file = output.packageApplication.outputFile
        def fileName = file.name.replace(".apk", "-" + defaultConfig.versionName + ".apk")
        output.packageApplication.outputFile = new File(file.parent, fileName)
    }
}

Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated
