The Design Patterns Research Of Android Source Code To Improve Application Development

With the continuous improvement of communication technology,mobile terminal equipment has gained widespread. The number of users of smart phones, tablets and other devices is increasing rapidly. As an excellent open source mobile operating system, Android continues to expand its scope of application. More and more developers focus on Android application development.However, the developers pay much attention to complete the function in a very short time, as result, the products they developed exist problems like high memory consumption, memory leaks, high coupling degree, and poor scalability. Quality of mobile application software,reliability and extensibility of software, and reduce the degree of code coupling have become the current research hotspots.Firstly, this paper introduces the concepts and related techniques of the design patterns in Android source code. Secondly, the design patterns in Android source code are analyzed in this paper. Thirdly, this paper shows a development comparison on applying design patterns and without design patterns. Then, the main work and defects are summarized in this paper. The main work: By analyzing the source code of Android system Framework layer, the design patterns and special situations are summarized for Application layer. Applying the design patterns can make positive effects, such as improve software quality, reducing code coupling, and increase scalability, etc. Finally, shortcomings of this paper are analyzed and prospects for future work are presented.
