基于Android平台的嵌入式调频广播系统设计

The Design of Embedded FM Radio System Based on Android Platform

为了满足移动用户对智能终端更高的需求,开发了基于Android平台的调频广播系统。在研究嵌入式调频广播系统硬件设计的基础上,重点介绍了Android系统内核层驱动程序、硬件抽象层(HAL)接口及Java本地调用(JNI)函数的设计和Eclipse环境中应用程序的开发,实现了调频广播系统搜台、播放和切换频道等功能。

A FM radio system based on Android is designed in order to meet the demand of mobile consumers to the intelligent terminal.Based on the study of Embedded FM radio hardware system design,the technologies are mainly researched in this paper such as the design of Android system kernel drivers,HAL（Hardware Abstraction Layer） interface and JNI（Java Native Interface） function,and development of the corresponding software in the Eclipse environment,whose functions include searching radio stations,playing,and switching channels etc.
