Options to configure Multiple APKs.

[`android`](https://developer.android.com/reference/tools/gradle-api/7.2/com/android/build/api/dsl/ApplicationExtension#splits(kotlin.Function1))`.`[`splits`](https://developer.android.com/reference/tools/gradle-api/7.2/com/android/build/api/dsl/Splits)

If you publish your app to Google Play, you should build and upload an[Android App Bundle](https://developer.android.com/guide/app-bundle). When you do so, Google Play automatically generates and serves optimized APKs for each user's device configuration, so they download only the code and resources they need to run your app. This is much simpler than managing multiple APKs manually.

If you publish your app to a store that doesn't support the Android App Bundle format, you can publish[multiple APKs](https://developer.android.com/studio/build/configure-apk-splits.html)manually.

The Android Gradle plugin supports generating multiple APKs based on screen density and[Application Binary Interface (ABI)](https://developer.android.com/ndk/guides/abis.html), where each APK contains the code and resources required for a given device configuration.

You will also need to[assign version codes to each APK](https://developer.android.com/studio/build/configure-apk-splits.html#configure-APK-versions)so that you are able to manage updates later.

Previously the Android Gradle plugin also supported building 'Configuration APKs' for Instant Apps using this`splits`block, but that has been superseded by the Android App Bundle format.
