Research And Development Of Applications Based On Mobile Platforms And The Interface Of Third Party Payment

As an emerging and burgeoning industry, mobile internet appeals to people all over the world. Android has dominated the mainstream market rapidly and won a wide support from mobile terminal vendors and developers, just owning to its open source. Third Party Payment, as a business model of Android, owns a great potential value. This thesis emphasizes the research and development of mobile applications based on Android platform, and Third Party Payment represented by Alipay integrated in the applications to realize payment inside mobile applications.Firstly, game development frame based on Android platform has been proposed, and each function module has been designed and realized, focusing on the paint deformation of pictures, the zoom manually of game scene and the change of views using multi-threaded asynchronous communication mechanism. Then music playing, lyrics parsing and synchronizing, playback progress displaying and music downloading have been implemented.Secondly, the MicroBlog client based on OAuth has been designd, developed and optimized. The microblogging client’s specific implementation process has been detailed. A thread started in the client application requests data from the microblogging server and returns the data from asynchronous communication mechanism between threads. Operating principles of loading data in list has been analyzed and studied to enchance the loading speed with system cache and entity class. The images on the network have been downloaded asynchronously and cached, reducing the memory consumption of mobile devices and improving the performance of the whole system. It has better using experiences and application values.Finally, after having researched and analyzed the entire payment process and core technologies of Alipay’s secure payment system, the paper builds the framework of mobile payment system based on different payment business needs of the mobile applications. The payment of Alipay in mobile games has accomplished payment inside mobile applications successfully. At the same time, in order to ensure the security of the entire payment process, the paper has designed and developed a server. This server interacts with the client and the Alipay server, signs the order information of the client and verifies the payment results of the Alipay server.
