远程进程调用

远程段:1   IService.aidl文件和RemoteService类.

package cn.itcast.remoteservice;

interface IService {
 void callMethodInService();
}

package cn.itcast.remoteservice;

import android.app.IntentService;
import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;
import android.test.IsolatedContext;

public class RemoteService extends Service {

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

	
	private class MyBinder extends IService.Stub{

		@Override
		public void callMethodInService() throws RemoteException {
			sayHelloInService();
			
		}
		
	}
	
	/**
	 * 服务里面的一个方法 
	 */
	public void sayHelloInService(){
		System.out.println("hello in service");
	}
	
	@Override
	public void onCreate() {
		System.out.println("remote service oncreate");
		super.onCreate();
	}

}

2.客户端.把aidl文件copy过来和调用远程服务的activity.

package cn.itcast.remoteservice;

interface IService {
 void callMethodInService();
}

package cn.itcast.callremote;

import cn.itcast.remoteservice.IService;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.IBinder;
import android.os.RemoteException;
import android.view.View;

public class DemoActivity extends Activity {
	IService iService;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    	Intent intent = new Intent();
		//远程service的action.
    	intent.setAction("cn.itcast.remoteservice");
    	bindService(intent, new MyConn(), BIND_AUTO_CREATE);
    }
    
    
    public void click(View view){
    	try {
    		// 调用了远程服务的方法 
			iService.callMethodInService();
		} catch (RemoteException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
    }
    
    private class MyConn implements ServiceConnection{

		@Override
		public void onServiceConnected(ComponentName name, IBinder service) {
			iService = IService.Stub.asInterface(service);
			
		}

		@Override
		public void onServiceDisconnected(ComponentName name) {
			// TODO Auto-generated method stub
			
		}
    	
    }
}
