Abstract
Along with the information technology unceasing renewal, especially 07 years Google Corporation has launched the Android open source operating system, Android has become the darling of the mobile platform, widely used two-dimensional code and Android intelligent mobile phone further popularization, through the Android platform under the camera and drawing function, the coding and decoding principle of two-dimensional code, through the Android mobile phone the two-dimensional code data parsing and coding, the realization of two-dimensional code express generation and recognition system.
The design is based on the two-dimensional code express information query system of Andriod platform, using C/S model, analyzes the logic and function classification of two-dimensional code recognition system based on the delivery, and by the quick response code (QR Code) generation and recognition technology, through the intelligent mobile phone camera to identify two-dimension code information. The system uses the Java mode of MVC and eclipse development tools, from demand analysis to the game design, implementation, debugging, and ultimately to achieve the mobile phone two-dimensional code recognition and generation function. After rigorous testing, and can be used in the mobile phone.

Key words: mobile phone; Android; two-dimensional code Express; Java
