Android Compatibility Definition: Android 1.6

This paper enumerates the requirements that must be met in order for mobile phones to be compatible with Android 1.6. The Android platform includes both a set of managed ("Hard") APIs, and a body of so-called "Soft" APIs such as the Intent system, native-code APIs, and web-application APIs. This paper details the hard and soft APIs that are integral to compatibility, as well as certain other relevant technical and user interface behaviors.
