文件aidl的使用方法

public class PhoneSubInfoController extends IPhoneSubInfo.Stub

./frameworks/opt/telephony/src/java/com/android/internal/telephony/PhoneSubInfoController.java./frameworks/base/telephony/java/com/android/internal/telephony/IPhoneSubInfo.aidl

进程间通信 IPhoneSubInfo.aidl可以生成IPhoneSubInfo.java文件，里面包含IPhoneSubInfo.Stub接口，PhoneSubInfoController.java实现了它

编译器自动生成了，编译时就会出现，

IPhoneSubInfo.aidl和这个里面接口一样的，只是按一定规范生成JAVA文件

./out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/src/telephony/java/com/android/internal/telephony/IPhoneSubInfo.java
