Overview of Changes, Android 0.9 to Android 1.0 SDK

This document provides information to help you port your applications from Android 0.9 SDK to Android 1.0 SDK. It describes new features available to your application, as well as API changes that you may need to integrate into your code. For detailed information about API additions, removals, and changes, see the API Diffs report.

Note that this document (and the associated API Diffs Report) covers only the changes from Android 0.9 SDK to Android 1.0 SDK. For your convenience, this SDK includes legacy documentation of changes from the M5 release to Android 0.9 SDK. For more information, see Overview of Changes, M5 to Android 0.9 and API Diffs Report, M5 to Android 0.9.

If your application is based on an early-look SDK such as release M3, you may want to refer to the documentation in the M5 SDK for information about migrating to that release, as a base from which to migrate to 0.9 or directly to 1.0.
