About Android 14 Developer Preview 2

Developer Preview 2 is now available, with the latest features and changes to try with your apps. This release is for developers only, to help with early development, testing, and feedback. Android 14 Developer Preview 2 is an early baseline build that's still in active development, so the Android system and apps running on it might not always work as expected.

As with previous versions, Android 14 includes behavior changes to help improve performance, battery life, security, and privacy. In some cases, these changes can affect apps until they are updated to support Android 14, so you might see impacts ranging from minor issues to more significant limitations. In general, most apps will work as expected, as will most APIs and features, but please review any known issues listed on this page to get a better idea of what to expect.
