FM-radio

基于Android4.0.3 Linux3.0，增加Linux驱动，改动Frameworks层，增加APK

---

1.tea5767驱动程序 2.Frameworks层增加API接口 3.Android应用程序控制tea5767芯片实现收音机功能

----------20170711 update
1.增加驱动代码
iTop4412_Kernel_3.0/drivers/char/tea5767.c
iTop4412_Kernel_3.0/drivers/char/i2c_tea5767.c
iTop4412_Kernel_3.0/drivers/char/i2c_tea5767.h

2.增加HAL层代码
hardware/libhardware/modules/hwfm/hwtea5767.c
hardware/libhardware/modules/hwfm/Android.mk
hardware/libhardware/modules/Android.mk
hardware/libhardware/include/hardware/hw_tea5767.h

3.增加JNI代码
frameworks/base/services/jni/com_android_server_FMService.cpp
frameworks/base/services/jni/onload.cpp
frameworks/base/services/jni/Android.mk

4.增加Frameworks代码
frameworks/base/core/java/android/os/IFMService.aidl
frameworks/base/Android.mk
需要先编译生成java文件：mmm frameworks/base
frameworks/base/services/java/com/android/server/FMService.java frameworks/base/services/java/com/android/server/SystemServer.java

5.增加APP代码
注：暂未调用系统的API，而是采用APP->JNI(NDK)->Driver模式，后续有时间会更改为调用系统API，即import以下包获取FMservice服务
import android.os.ServiceManager;
import android.os.IFMService;
private IFMService fmService = null;
fmService = IFMService.Stub.asInterface(ServiceManager.getService("fm5767"));
