We very strongly recommend adding custom APIs through a separate shared library, as shown in the PlatformLibrary sample, rather than modifying the framework library. This will make things a lot easier for you (easier to maintain patches or even no patches at all, works well with SDK tools), and ensures that apps correctly report the special APIs they need (via uses-library) so that the system and market can know whether they are compatible with the device they are being installed on.
