Version 0.16: Beta MR8 (Early Access)

This is the eighth openly available release of the Oppia Android app. Anyone can opt into the beta program and install the app on their Android device via the Play Store. Burndown milestone: https://github.com/oppia/oppia-android/milestone/54.

This release brings a variety of significant crash and bug fixes, and a number of stability improvements due to the introduction of new developer workflow tooling (lint testing). This also is preparing an alpha version of the app for testing the following features:

• Spotlights.
• Multiple classrooms (only with math content for now).
• The new onboarding flow (for the parts complete so far).
• Flashbacks (a new feature developed this summer).

The developer version of the app now includes a dashboard for changing platform parameters and feature flags at runtime for an easier time with testing or developing against different configurations.

The production version of this release is set to expire on 30 September 2026.
