本文将带你了解Android应用开发Android AIDL实现两个APP间的跨进程通信实例，希望本文对大家学Android有所帮助。

本文为大家分享了Android   AIDL实现两个APP间的跨进程通信实例，供大家参考，具体内容如下

1   Service端创建

首先需要创建一个Android工程然后创建AIDL文件，创建AIDL文件主要为了生成继承了Binder的Stub类，以便应用Binder进行进程间通信

servier端结构如下

AIDL代码如下

// IBookManager.aidl

package com.example.bookserver.aidl;

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

import com.example.bookserver.aidl.Book;

interface IBookManager {

 /**

  * Demonstrates some basic types that you can use as   parameters

  * and return values in   AIDL.

  */

 void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat,

   double aDouble, String   aString);

 List<Book>   getBook();

 boolean addBook(in Book   book);

}

package com.example.bookserver.aidl;

parcelable   Book;

之后创建一个实现了Parcelable的Book.java类用来传递数据

package com.example.bookserver.aidl;

import android.os.Parcel;

import android.os.Parcelable;

/**

 *   Created by SAMSUNG on 2016-09-07.

 */

public class Book implements Parcelable {

 private int id;

 private String name ;

 public int   getId()   {

  return id;

 }

 public void setId(int id) {

  this.id = id;

 }

 public String getName() {

  return name;

 }

 public void setName(String name) {

  this.name = name;

 }

 @Override

 public String toString() {

  return "Book{" +

    "id=" + id +

    ", name='" + name + '\'' +

    '}';

 }

 @Override

 public int describeContents() {

  return 0;

 }

 @Override

 public void writeToParcel(Parcel dest, int flags) {

  dest.writeInt(this.id);

  dest.writeString(this.name);

 }

 public Book() {

 }

 protected Book(Parcel in) {

  this.id = in.readInt();

  this.name = in.readString();

 }

 public static final Parcelable.Creator<Book> CREATOR =   new   Parcelable.Creator<Book>()   {

  @Override

  public Book createFromParcel(Parcel source)   {

   return new Book(source);

  }

  @Override

  public Book[] newArray(int size) {

   return new Book[size];

  }

 };

}

最后我们来写一个Service用于客户端绑定

package com.example.bookserver.service;

import android.app.Service;

import android.content.Intent;

import android.os.Binder;

import android.os.IBinder;

import android.os.RemoteException;

import com.example.bookserver.aidl.Book;

import   com.example.bookserver.aidl.IBookManager;

import java.util.List;

import java.util.concurrent.CopyOnWriteArrayList;

public class BookService   extends   Service   {

 private CopyOnWriteArrayList<Book> boookList =   new   CopyOnWriteArrayList<Book>();

 public BookService() {

 }

 Binder binder = new IBookManager.Stub(){

  @Override

  public void basicTypes(int anInt, long aLong, boolean aBoolean, float aFloat, double aDouble, String aString) throws RemoteException   {

  }

  @Override

  public List<Book> getBook()   throws   RemoteException   {

   return boookList;

  }

  @Override

  public boolean addBook(Book book) throws RemoteException {

   return boookList.add(book);

  }

 };

 @Override

 public IBinder onBind(Intent intent)   {

  return binder;

 }

 @Override

 public void onCreate() {

  super.onCreate();

  Book book = new Book();

  book.setId(12345);

  book.setName("Book 1");

  boookList.add(book);

 }

}

这样Server端就搞定了，接下来就该进行Client端的代码编写了

2   Client端

Client端结构如下

首先我们要讲AndroidStudio   通过AIDL生成的Binder导入到Client中并将Book.java也导入到Client中  
然后写进行Service的绑定
