传递数据
自定义类型 要实现parceable 接口
并定义同名的aidl文件 文件内容parcealbe 类名
实现接口回调：
要实现接口 接口用aidl定义这样才能执行，在不同进程间的对象的hashcode是不样的，因此正常是无法回调的
接口也用aidl MyLatLngListenerAidl.aidl
package com.p2.pa.amap.location;
interface MyLatLngListenerAidl
{
void receiverLatLng(double lat,double lon);
}
实现类
public class MyLatLngListener extends MyLatLngListenerAidl.Stub {
ActivityMain context;
private AMap map;
public MyLatLngListener(AMap map, ActivityMain activityMain) {
super();
this.map = map;
this.context = activityMain;
}
@Override
public void receiverLatLng(double lat, double lon) throws RemoteException {
System.out.println("MyLatLngListener receiverLatLng lat:" + lat
+ ",lon:" + lon);
locationOk(new LatLng(lat, lon));
}
服务调用，绑定连接成功后添加侦听
class MyLocatonConnection implements ServiceConnection {
@Override
public void onServiceConnected(ComponentName arg0, IBinder arg1) {
printLog("onServiceConnected");
aidl=LocationServiceAidl.Stub.asInterface(arg1);
isBind = true;
try {
MyLatLngListener listener = new MyLatLngListener(aMap, ActivityMain.this);
printLog("MyLatLngListener:"+listener.hashCode());
aidl.addListener(listener);
} catch (RemoteException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

//android service一直再运行，通过bindService拿到service的代理，并将自己到回调对象注册过去，就能实现调用service中的方法，和在service中调用本地activity到方//法。做到了进程间通信。
