Smartphones are powerful devices that can support diverse tasks from graphically intensive games to helping people get work done from anywhere. We understand that developers are challenged with delivering a delightful user experience that maximizes the hardware of the device, while also ensuring that their users can download, install, and open the app as quickly as possible. It’s a tough balance to strike, especially when you’re targeting diverse global audiences.

To support the growing number of developers who are building richer apps and games on Google Play, we are increasing the APK file size limit to 100MB from 50MB. This means developers can publish APKs up to 100MB in size, and users will see a warning only when the app exceeds the 100MB quota and makes use of Expansion Files. The default update setting for users will continue to be to auto-updating apps over Wi-Fi only, enabling users to access higher quality apps and games while conserving their data usage.

Even though you can make your app bigger, it doesn’t always mean you should. Remember to keep in mind the following factors:

Mobile data connectivity: Users around the world have varying mobile data connectivity speeds. Particularly in developing countries, many people are coming online with connections slower than those of users in countries like the U.S. and Japan. Users on a slow connection are less likely to install an app or game that is going to take a long time to download.

Users on a slow connection are less likely to install an app or game that is going to take a long time to download. Mobile data caps: Many mobile networks around the world give users a limited number of MB that they can download each month without incurring additional charges. Users are often wary of downloading large files for fear of exceeding their limits.

The larger your app or game, the slower it may run, particularly on older devices.

Install time: People want to start using your app or game as quickly as possible after tapping the install button. Longer wait times increase the risk they’ll give up.

We hope that, in certain circumstances, this file size increase is useful and enables you to build higher quality apps and games that users love.
