很多人对AIDL的使用还是不太清楚,自己也在运用中也遇到了不少麻烦,在这里我就简单示例了一个DEMO，之前也参考过相关的文章,所以在这里就直接贴源码了,希望能给有关人士带来帮助,并以思维导图的方式进行描述：

上面是贴图,下面就直接是源码了:

A_To_B:project

MainActivity.java:

package com.jsd.aidl;

import com.jsd.aidl.service.RemoteService;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

/**
*
* @author jiangshide
*
*/
public class MainActivity extends Activity{

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
getViewById();
}

public void getViewById(){
Button start = (Button) findViewById(R.id.startService);
start.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent intent = new Intent();
intent.setClass(MainActivity.this, RemoteService.class);
startService(intent);
}
});
}

}

Data.aidl:

package com.jsd.aidl.service;

parcelable Data;

ICommonService.java:

package com.jsd.aidl.service;
import com.jsd.aidl.service.Data;
interface ICommonService{
String addString(String str);
void addData(in Data data);
Data getData();
}

RemoteService.java:

package com.jsd.aidl.service;

import android.os.Parcel;
import android.os.Parcelable;
import android.util.Log;

/**

public class Data implements Parcelable {

private static String TAG = "Data";
public Data(Parcel source){
name = source.readString();
type = source.readInt();
addr = source.readString();
Log.i(TAG, name);
}
public static final Parcelable.Creator<Data> CREATOR = new Parcelable.Creator<Data>() {
@Override
public Data createFromParcel(Parcel source) {
return new Data(source);
}

@Override
public Data[] newArray(int size) {
Log.i(TAG, size+":");
return new Data[size];
}

};
@Override
public int describeContents() {
return 0;
}
@Override
public void writeToParcel(Parcel dest, int flags) {
Log.i("TAG", "dest:"+name);
dest.writeString(name);
dest.writeInt(type);
dest.writeString(addr);
}

private String name;
private int type;
private String addr;
public Data(){
}
public Data(String name ,int type,String addr){
this.name = name;
this.type = type;
this.addr = addr;

}
public String getAddr() {

}

this.addr = addr;
}
@Override
public String toString() {
return "Data [name=" + name + ", type=" + type + ", addr=" + addr + "]";
}
}

以上就是一个简单的两个应用之间实现通行的简单过程,如果需要的朋友可以参看更详细的官方文档
