Add or test APK expansion files

Starting August 2021, new apps are required to publish with the Android App Bundle on Google Play. New apps larger than 200MB can use either Play Asset Delivery or Play Feature Delivery.

As of June 30, 2023, Google Play no longer supports TV app updates using APKs. All TV app updates must be published with Android App Bundles (AAB).

If your app needs more than 100MB of memory, you can use expansion files to store additional APK assets. You can store two expansion files per app. Each expansion file can be up to 2GB in size.

APK files have a maximum file size, based on the Android version your APK supports:

• 100MB - APKs that target Android 2.3 and higher (API level 9-10 and 14+)
  • Users must run Play Store version 5.2 or higher to install 100MB APKs.

Expansion files are hosted at no additional cost. When possible, Google Play downloads expansion files when apps are installed or updated. In some cases, your app will need to download its expansion files.

If the compressed size of your APK at the time of download (including expansion files) is larger than 200MB, users will see a warning dialog suggesting that they use Wi-Fi to download your app.

Tip: By publishing your app using the Android App Bundle, you can build and deliver smaller, more efficient apps for users to install.

Expansion file types

When you use expansion files, one file is the main file and the other is an optional patch file. Optional patch files are usually used for small updates to the main file.

Expansion files can be any type of file and are saved to a device’s shared storage location (for example, SD card or USB-mountable partition) where your app can access them. Every expansion file URL issued is unique to every download.
