Last November it was released the Android SDK, the first open mobile platform leaded by Google. To Promote development of applications for Android, next January 2, 2008 is beginning the Android Developer Challenge, which will provide $10 million in awards. I present an example to connect Android platform to SAP NetWeaver, feel free to use it in your applications, you have a big opportunity to participate in this incredible "ten million dollars developer challenge".
Notes:
- You can use Android SDK in your Composition Environment or in your eclipse installation.
- Your Android emulator call to SAP NetWeaver backend by http/rfc. Android device/emulator is in public network and your ERP/CRM backend in a private network, you need to put a middleware, which take http public requests and convert them in RFC private calls, You can configure your PI/XI application to do it or try a simple middleware for testing your prototype ( The thinnest SOA middleware for SAP NetWeaver ).
Install Android SDK, Eclipse plugin and make your first Android application called AndroidSAP.
