I got solution from here Migrate to Android Plugin for Gradle 3.0.0

android.applicationVariants.all { variant ->
    variant.outputs.all {
        outputFileName = "${variant.name}-${variant.versionName}.apk"
    }
}

Answer 2

This worked for me!

1. Open app.graddle file, and replace in applicationVariants.all... with

android.applicationVariants.all { variant ->
        variant.outputs.all {
            outputFileName = "${variant.name}-${variant.versionName}.apk"
        }
    }

2. Build-> Make project
3. Then Generate your signed APK
