Porting to Series 40

For porting Android applications to the Series 40 platform, see Porting to Series 40.

You can expand your application coverage by porting your Android applications to Series 40. The porting process is explained with the help of two complete application porting cases: a game and a social media application. The library contains code snippets on important application areas and technologies, feasibility comparisons on application types and segments, and a user interface comparison between Android and Series 40 touch devices.
