Files handling. - Google Maps, their usage and displaying various items on map - GPS handling and location-based services - Bluetooth programming - Mobile Zebra printer programming and handling from and Android app - Using XLS files in an Android app Also: - Databases (Postgres, MySQL) - Web (PHP, HTML, CSS) I develop business apps, entertainment apps, 2d games - on request. My customer references: YarMobile has delivered a high quality, polished application. The company\'s performance met our requirements, which was very important, as we are not an IT company. YarMobile managed to effectively translate our expectations into solid software and deliver it on time. Piotr Świątkiewicz - Plant manager at SFB Polska Jaroslaw is a determined person and has a clear plan for the project. Accurate and stubborn at his work, imposing strict discipline and work culture. The combination of these features makes the project proceed quickly and efficiently to its completion, and the final work is what has been described in the specification. I recommend YarMobile to all those for whom effective implementation of IT projects matters. There are few such in the market. Sławomir Łebkowski - Companion
