写一个简单的AIDL

1.首先创建一个AIDL文件，并添加上两个接口。
IMyAidlInterface.aidl

package com.example.broadcastdemo;

// Declare any non-default types here with import statements

interface IMyAidlInterface {

    void request();
    String getName();
}

2.编写服务端实现AIDL相应的接口
MyService.java

public class MyService extends Service {
    public MyService() {
    }

    private final IBinder iBinder = new IMyAidlInterface.Stub() {
        @Override
        public void request() throws RemoteException {

        }

        @Override
        public String getName() throws RemoteException {
            return "您好，我的名字叫服务端";
        }
    };

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public IBinder onBind(Intent intent) {
        return iBinder;
    }

}

3：使用

private void binAidl() {
    if (myAidlInterface == null) {
        try {
            Intent intent = new Intent("com.example.broadcastdemo.MyService");
            intent.setPackage("com.example.broadcastdemo");
            boolean result = bindService(intent, ServiceConnection, Context.BIND_AUTO_CREATE);
            Log.e(TAG, "createPopupServiceConnection: result " + result);
        }catch (Exception e){
            Log.e(TAG, "createPopupServiceConnection: Exception" + e.getLocalizedMessage());
        }

    }
}

private android.content.ServiceConnection ServiceConnection = new ServiceConnection() {
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        Log.e(TAG, "onServiceConnected: ServiceConnection");
        myAidlInterface = IMyAidlInterface.Stub.asInterface(service);
    }

    @Override
    public void onServiceDisconnected(ComponentName name) {
        Log.e(TAG, "onServiceDisconnected: ServiceConnection");
        myAidlInterface = null;
    }
};

private void getName(){
    if (myAidlInterface != null) {
        try {
            String str = myAidlInterface.getName();
            Log.e(TAG, "" + str);
        } catch (RemoteException e) {
            e.printStackTrace();
        }
    }
}
