Update the Android Gradle Plugin as a Compatible Toolchain

Record the current build before changing it

Save the AGP version, wrapper distribution, JVM used by Gradle, Android Studio version, compile SDK and important build plugins. Confirm that the current release builds and tests pass so regressions have a baseline.

The AGP release notes identify compatibility and migration changes. Consult the release you intend to adopt, not only a generic “latest version” page.

Plan the compatibility tuple

Do not confuse the Java source language level with the JVM running Gradle. The Android JDK guide explains these separate roles.

Upgrade in a reviewable branch

Update the selected plugin and compatible wrapper, then address documented DSL or behavior migrations. Keep unrelated dependency upgrades out of the same change where possible. A smaller diff makes a new release-only crash or packaging change easier to attribute.

Use the wrapper update procedure and commit all required wrapper changes, not only a modified URL.

Validate more than sync

Run the release build, local tests, instrumentation tests where available, lint and any native or dynamic-feature builds. Inspect signing, manifest values, resource shrinking and output sizes. A successful IDE sync only proves the model imported; it does not prove the release behavior is unchanged.

Keep a rollback path

Retain the prior toolchain and release artifact until the new build is validated. APKLint's Build Analyzer can highlight configuration issues, and its APK tools can compare the resulting package. Neither can guarantee compatibility with every private plugin or compile your project from a short configuration excerpt.
