  Many companies include in their Information Systems (IS) several
communicating heterogeneous middleware according to their technical needs. The
need is the same when IS requires using context aware platforms for different
aims. Moreover, users may be mobile and want to receive and send services with
their PDA that more often supports Android based Human Man Interface. In this
paper, we show how we extend Android to make it adaptable and open. We also
present how we communicate between different heterogeneous context aware
platforms as WComp and OpenORB by using Android and Web Services. We introduce
a concrete case study to explain our approach.
