Mobile Internet Device (MID), as a portable handheld device, becomes a strong candidate for client-side computing. Android is a mobile operating system, being accepted as the operating system and a platform for MID applications. However, MID has a limited resource and computing power, and Android has an architecture and its components which are not commonly found in other operating systems and platforms. Hence, there is a demand for effective methodologies for modeling and implementing Android-based MID applications. In this paper, we present a practical and systematical process for develop applications for Android-based MID. Our process utilizes both object-oriented and service-oriented engineering principles while considering features of MID and the architecture of Android.
