Welcome! The developer preview gives you everything you need to get your apps ready for Android 12, with system images and tools updated regularly throughout the cycle. During Developer Preview 1, the goal is to try the new APIs and test with platform changes, then let us know of any issues or requests. It's especially important to give us feedback early, so we have more time to include it in the final release.
