AIDL——兩個APP數據通信

一.創建服務端servier和接口

   1.新建aidl文件並新建相應的文件

    Book

package com.study.myapplication;

import android.os.Parcel;
import android.os.Parcelable;

public class Book implements Parcelable {
    public int bookId;
    public String bookName;

    public Book(){}

    public Book(int bookId,String bookName){
        this.bookId=bookId;
        this.bookName=bookName;
    }

    protected Book(Parcel in) {
        bookId = in.readInt();
        bookName = in.readString();
    }

    public static final Creator<Book> CREATOR = new Creator<Book>() {
        @Override
        public Book createFromParcel(Parcel in) {
            return new Book(in);
        }

        @Override
        public Book[] newArray(int size) {
            return new Book[size];
        }
    };

    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(bookId);
        dest.writeString(bookName);
    }

    @Override
    public String toString() {
        return "Book{" +
                "bookId=" + bookId +
                ", bookName='" + bookName + '\'' +
                '}';
    }
}

Book.aidl

package com.study.myapplication;

parcelable Book;

IBookManger

// IBookManager.aidl
package com.study.myapplication;


import com.study.myapplication.Book;
interface IBookManager {
   List<Book> getBookList();
   void setBook(in Book book);
}

 2.新建服務端servier類

   並在AndroidManifest.xml文件註冊

    

<service
    android:name=".AIDLService"
    android:enabled="true"
    android:exported="true"
    android:process=":remote">
    <intent-filter>
        <action android:name="android.intent.action.AIDLService" />
    </intent-filter>
</service>

gradle文件添加
sourceSets {
    main {
        java.srcDirs = ['src/main/java', 'src/main/aidl']
    }
}

package com.study.myapplication;

import android.app.Service;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Binder;
import android.os.IBinder;
import android.os.RemoteException;

import java.util.ArrayList;
import java.util.List;

import androidx.annotation.Nullable;

public class AIDLService extends Service {
    private List<Book> mList = new ArrayList<>();

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

    private Binder binder = new IBookManager.Stub() {
        @Override
        public List<Book> getBookList() throws RemoteException {
            return mList;
        }

        @Override
        public void setBook(Book book) throws RemoteException {
            mList.add(book);
        }
    };


    @Nullable
    @Override
    public IBinder onBind(Intent intent) {

        return binder;
    }

    @Override
    public void unbindService(ServiceConnection conn) {
        super.unbindService(conn);
    }

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

 

 

2.創建客戶端連接server

 1.連接server調用接口

package com.study.two;

import androidx.appcompat.app.AppCompatActivity;

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.widget.Toast;

import com.study.myapplication.Book;
import com.study.myapplication.IBookManager;

import java.util.List;

public class MainActivity extends AppCompatActivity {
    private static final String TAG = MainActivity.class.getSimpleName();
    private IBookManager iBookManager;
    private final String ACTION = "android.intent.action.AIDLService";
    ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            Log.e(TAG, "已和服務端連接....");
            iBookManager = IBookManager.Stub.asInterface(service);
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
            iBookManager = null;
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //服務端 server路徑和報名
        Intent intent = new Intent(ACTION);
        intent.setPackage("com.study.myapplication");
        bindService(intent, connection, Context.BIND_AUTO_CREATE);
        findViewById(R.id.bt_start).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (iBookManager != null) {
                    List<Book> list = null;
                    try {
                        list = iBookManager.getBookList();
                        if(list==null||list.isEmpty()){
                            return;
                        }
                        for(int i=0;i< list.size();i++){
                            Toast.makeText(MainActivity.this,"value:"+list.get(i).toString(),Toast.LENGTH_SHORT).show();
                        }
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                    Log.d("TAG", "getBookList:" + list.size());
                }
            }
        });
        findViewById(R.id.bt_add).setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if (iBookManager != null) {
                    try {
                        iBookManager.setBook(new Book(100101, "蘇菲的世界"));
                    } catch (RemoteException e) {
                        e.printStackTrace();
                    }
                }
            }
        });
//        unbindService(connection);
    }
}
