Java/Android programmer needed (Belgrade)

Anasphere, Inc. manufactures atmospheric research instrumentation. One of our systems is tablet-based and runs on Android. We need a programmer to update an existing app which has developed problems with its serial communications routines as a result of both hardware and Android OS changes. Experience with USB communications using the USB port on Android devices is highly desirable. A further evolution of this app to use built-in Bluetooth is anticipated. At the present time, this could be either a short-term position or a contract arrangement; the potential exists for this to become a permanent position as well. We are also open to this being a side job done outside of normal working hours.
