With the development of technology, people’s social activities are not confined to the daily life as well as work circle,, With the Android tablet device, Internet-based social activities and information exchange are increasingly being seen as acceptable. In such a trend, social networking service (SNS) have sprung up, and gradually become a mainstream of Internet application technology. SNS, whose full name is Social Networking Service, is specifically designed to help people build the Internet application services of social networks. It’s based on social networking relationship. The theoretical basis of social network theory stems from Six Degrees of Separation and Rule of 150. Six Degrees of Separation theoretical core that is in the human and interpersonal relationships, if you wanted to know any stranger, it is necessary to pass six friends for achieving your goal mostly. Currently, SNS has been mature Internet technology, but with the traditional Internet applications, the user’s activities are confined to.

This paper introduces background knowledge of lashup at first about its emergence and development, common architecture, some of the key technologies, as well as related technologies about context-aware mobile application system in this paper, including transforming data format for various service providers. Then android is introduced as the platform of terminals such as android tablet, mainly about its architecture and application structure, especially technologies used in the mobile application system.

A context-aware android tablet application system is designed and implemented in the end of this paper. This system integrates data sources from different data providers on server-side, and converts them into a KML format file for output. You can select services, create Google Map and make lashups on client-side. A detailed description is given which is about functional design, overall architecture and implementation of key part of this system.

Communication mechanism between wireless headset and Android tablet. The core of the whole wireless headset system is composed of nRF24E1 master and nRF24El slave. nRF24El master is integrated with Smart phone, which exchanges customized control command with Smart phone by DART port. The definition of control command contains 6 bytes, and is Big-Endian. nRF24El slave is in wireless headset, and responsible for full duplex air transmission between nRF24El master and nRF24El slave. The payload of every air package contains customized command and data.ALSA device driver is focus on the management of wireless headset master and audio codec in ALSA, and supports wireless headset master in audio path management. Serial device driver is responsible for communication between wireless headset master and application processor.
