Research On Visual Development For Android Embedded Program Based On Rule

Mobile Internet develop rapidly in recent years, more and more people join the APP life.the Android operating system has become the focus of competition among the smartphone operating system.Therefore, more and more developers dedicated to development of Android embedded applications.In the process of the development of mobile terminal program,there are many UI developments of mobile terminal program with the aid of interface development tools.For the development of Android embedded application,developers always use the Eclipse development tools.Although the Eclipse development tool provides the function of the interface development,developers do not use this function because of its insensitive operation and the low efficiency of the design process.Currently, Android visual development tools don’t have the function that generate the Java code of Android application and frame structure.For the purpose of solving the problem of Android embedded visual development and the code automatic generation,based on analysis of the demands of visual development tools and in-depth study of the Android embedded application framework and project files,this paper puts forward a visual development method based on the rule.The method discusses the layout problem of the Android embedded application interface,defines many constraint rules between layouts and components.According to the constraint rules,it generate Layout-Widget interface framework that directed XML code generation for the Android embedded.Under the guidance of interface model and combining with the generation rules for XML file,it achieves a recursive generation for the XML file codes,at the same time, the efficiency of the code generation is improved.Meanwhile,it defines the Android component object and event listeners rule and code storage rule that is used to store a Java code block. Under the constraints of the Java file generated rules,it eventually generate Java file code for Android embedded.Finally. through batch program will file to compile, package, signature and generate executable apk application.Developers only need to drag the corresponding components, set properties, click on the corresponding generated button can develop Android embedded applications.lt improves the efficiency of the Android application development and reduce the development difficulty.
