Google Play Instant: Technical requirements checklist

The quality of your instant experience can influence the long-term success of your app or game in terms of installs, pre-registrations, growth, and user retention. Before making your instant experience available, it's important to make sure that the instant experience meets users' basic expectations.

This document helps you understand the quality level, feature set, and UX that your instant experience should attain to be successful. Each focus area presents a checklist of minimum requirements, best practices, and good-to-have enhancements. In the interest of delivering the best possible experience to your users, follow each checklist requirement, and follow the checklist recommendations to the greatest extent possible.

Note: To help prioritize your development efforts, take note of the level of importance indicated for each checklist item:

  • Required. Minimum requirements that must be implemented for your instant experience to be considered compatible with Google Play Instant.
  • Best practice. Strongly recommended implementation guidelines.
  • Good to have. Suggested guidelines to help you create a distinctive user experience.

  • Display a persistent button on the main screen.
  • Display a button between actions in your instant experience.

5.2 Required Users must not be required to make an in-app purchase before being able to engage with your instant experience. This requirement also applies to the full, installed version of your app or game.
