Change APK name in Android Gradle 8.1+ kts | AGP 8.1

Changing the APK name whenever AGP changes is tiresome work so I'm gonna jot down all the gradle versions and their way to change the APK name in it.

Fella android devs feel free to add more in the comments section. ;)

Gradle 8.1.4 kts

The following snippets work in KMP as well.

android {
...
applicationVariants.all {
    this.outputs
        .map { it as com.android.build.gradle.internal.api.ApkVariantOutputImpl }
        .forEach { output ->
            val variant = this.buildType.name
            var apkName =
                this.flavorName[0].uppercase() + this.flavorName.substring(1) + "_" + this.versionName
            if (variant.isNotEmpty()) apkName += "_$variant"
            apkName += ".apk"
            println("ApkName=$apkName ${this.buildType.name}")
            output.outputFileName = apkName
        }
}
...

Gradle 8.1+ kts

The following snippets work in KMM as well.

android {
...
  productFlavors {
      create("free") {
          dimension = "app"
          val appName = "Free App 2.0"
          manifestPlaceholders["appName"] = appName
          applicationIdSuffix = ".demo"
          versionName = "1.0.0"
          versionNameSuffix = ".3"
          versionCode = (versionName + versionNameSuffix).replace(".", "").toInt()
          val apkName = "${appName}_$versionName$versionNameSuffix($versionCode).apk"
  
          // change app name block below
          buildOutputs.all {
              val variantOutputImpl = this as com.android.build.gradle.internal.api.BaseVariantOutputImpl
              variantOutputImpl.outputFileName =  apkName
          }
      }
  }
}
