Play Core Library release notes

When you publish your app with an Android App Bundle, Google Play’s Dynamic Delivery allows your app to download dynamic feature modules on demand to devices running Android 5.0 (API level 21) and higher. Your app simply needs to call APIs in the Play Core Library to download and install those modules, and the Google Play Store pushes only the code and resources needed load that module on the device. You can also use this API to download on demand modules for your Android Instant Apps.

To learn how to first add dynamic feature modules to your project and configure them to be available on demand, read Create a dynamic feature module.

If you want to see the Play Core Library in action, try the Play Core Library sample app.

This page explains how to keep the library up to date and what's in the recent updates.

Include the Play Core Library in your project

Before you can start using the Play Core Library, you need to first import it into your app module as a Gradle dependency, as shown below:

// In your app’s build.gradle file:
dependencies {
    // This dependency is downloaded from the Google’s Maven repository.
    // So, make sure you also include that repository in your project's
    // top-level build.gradle file.
