In this paper, we describe the design and implementation of a RESTful
NAS service running on Android platform. Because most Android devices
deploy low-end CPU and wireless network ports, people rarely consider
building web services on Android. However, in this paper, we
demonstrate that it is possible and feasible to build and run web
services on Android. Our customers are family-level users, who care
more about the cost, bandwidth, and capacity. Our system exposes
RESTful API to achieve flexibility. It uses Rabin-fingerprint
algorithm to split files to save storage capacity. In order to reduce
response time, file segments are cached in a LRU cache. Clients may
specify which file or segment to download. The current design supports
client-side multi-thread downloading and job resuming. The server is
supposed to run on an Android smart device. The goal is to examine the
possibility to host practical services on Android platform.
