In Android system, black box testing has risen to three key issues: S1: There is no source code and for tester to know the internal logic of the testing App. S2: There is no testing criterion for tester to know the correct behavior and testing scope of the testing App. S3: It is difficult to measure the testing coverage without instrumentation the testing App. In this paper, we provide a approach to analyze the GUI model during the testing process, implement the a black-box based android GUI testing system and select 7 Apps for evaluation. Finally we compare our result of our system with the monkey tool and discuss the inner App's properties that influence on the testing result.

This study designs and implements a cross-platform, cross-domain P2P multimedia sharing system in the Taiwan Advance Research and Education Network. The system allows users to easily access the multimedia resources of the entire network from any network node, and all multimedia providers can share local multimedia resources from any location on the entire network. Moreover, this is a Peer-to-Peer based transmission architecture model, thus, users can easily maintain the network, and enhance the service quality and efficiency of the entire network through relevant mechanisms.
