Android Gradle plugin 9.0 is our second major release of AGP since we changed the versioning scheme in 2020. As a major version under semantic versioning, we have both API and behavior changes that mean this update might be a bit more work, but that also deliver benefits that make it worth keeping up to date. In this session we'll cover - Recommendations for practice for low-risk upgrades - Our compatibility and support goals for AGP - A summary of the changes were made and why in AGP 9 - The new variant API, best practice in extending Gradle/AGP builds with worked examples. - New defaults and e.g. fewer things enabled by default for better performance and scalability. - Implications of Gradle 9.0 requirement. - What's coming up in AGP 10 and above.
