不采用AIDL文件的service

服务：

package com.example.test3;

import android.app.Service;

import android.content.Intent;

import android.os.Binder;

import android.os.IBinder;

import android.os.Parcel;

import android.os.RemoteException;

import android.util.Log;

public class MyService extends Service {

 private static final java.lang.String DESCRIPTOR = "com.example.test3.aa";

 static final int TRANSACTION_ss = (android.os.IBinder.FIRST_CALL_TRANSACTION + 0);

 private static final String TAG = "MyService3";

 @Override

 public IBinder onBind(Intent intent) {

  Log.e(TAG, "onBind");

  return new MyBinder();

 }

 class MyBinder extends Binder {

  @Override

  protected boolean onTransact(int code, Parcel data, Parcel reply,

    int flags) throws RemoteException {

   switch (code) {

   case INTERFACE_TRANSACTION: {

    reply.writeString(DESCRIPTOR);

    return true;

   }

   case TRANSACTION_ss: {

    data.enforceInterface(DESCRIPTOR);

    reply.writeNoException();

    int i = data.readInt();

    Log.e(TAG, "MyService3 " + i);

    reply.writeInt(i);

    return true;

   }

   }

   return super.onTransact(code, data, reply, flags);

  }

 }

}

客户端：

package com.example.test4;

import android.app.Activity;

import android.content.ComponentName;

import android.content.Context;

import android.content.Intent;

import android.content.ServiceConnection;

import android.os.Bundle;

import android.os.IBinder;

import android.os.RemoteException;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

public class Client extends Activity implements OnClickListener {

 private static final String TAG = "MainActivity";

 aa mProxy ;

 private static final java.lang.String DESCRIPTOR = "com.example.test3.aa";

 static final int TRANSACTION_ss = (android.os.IBinder.FIRST_CALL_TRANSACTION + 0);

 @Override

 protected void onCreate(Bundle savedInstanceState) {

  super.onCreate(savedInstanceState);

  this.setContentView(R.layout.activity_main);

  this.findViewById(R.id.button1).setOnClickListener(this);

  Intent service = new Intent("com.example.test3.MyService2");

  ServiceConnection conn = new ServiceConnection() {

   @Override

   public void onServiceDisconnected(ComponentName name) {

   }

   @Override

   public void onServiceConnected(ComponentName name, IBinder obj) {

    mProxy =new Proxy(obj);

   

   }

  };

  this.bindService(service, conn, Context.BIND_AUTO_CREATE);

 }

 private static class Proxy implements aa {

  private android.os.IBinder mRemote;

  Proxy(android.os.IBinder remote) {

   mRemote = remote;

  }

  public int ss(int i) {

   android.os.Parcel _data = android.os.Parcel.obtain();

   android.os.Parcel _reply = android.os.Parcel.obtain();

   int _result=-1;

   try {

    _data.writeInterfaceToken(DESCRIPTOR);

    _data.writeInt(i);

    mRemote.transact(TRANSACTION_ss, _data, _reply, 0);

    _reply.readException();

    _result = _reply.readInt();

   } catch (RemoteException e) {

    e.printStackTrace();

   } finally {

    _reply.recycle();

    _data.recycle();

   }

   return _result;

  }

 }

 @Override

 public void onClick(View v) {

   Log.e(TAG, "" + mProxy.ss(752));

 }

}

重要：  Binder.onTransact    IBinder.transact
