The Design and Simulation of Embedded MP3 Player Based on Android Platform
|Keywords||Android platform MP3 player Decoding technology Real-time operating system|
Google's Android platform is the latest release of a mobile platform for mobile devices assembly includes an operating system , a middleware and some key applications . The platform does not require any fees to use the code completely open . Developers can quickly develop on the platform , and you can take advantage of the work of other developers . So, this is mobile phone development to create more flexibility , less work , short cycle , rapid prototyping, and in one step, while users can maximize their mobile phones customized to enrich your phone's functionality , increasing the phone , market competitiveness. Android platform to a Linux system as a platform basis , using the Linux kernel can accelerate software migration speed. In this paper, based on Android mobile development platform , briefly introduced the mobile terminal technology from birth to maturity of the development process, technical characteristics, and the current development status at home and abroad . Discusses the embedded real-time operating system (RTOS) works, describes the structure of MP3 files and MP3 file decoding processes. In the theoretical basis of the above discussion, the detailed description of the Android mobile development platform development environment. After the Android mobile phone platform based on the MP3 transmitters system made ??a detailed needs analysis . In the requirements analysis begins after the end of the system for MP3 transmitters detailed software design . Android development platform based on the structural characteristics of their own , I put the MP3 player is divided into two parts developed for the analysis and design , the design part of the window , the main window is to define the properties and associated window handler ; another part is a functional implementation , mainly Android mobile phone platform is a combination of the resources available and our MP3 player function analysis ultimately achieve our defined functions. Finally, based on the Android mobile development platform for the MP3 player system for functional testing and validation.
