Android IPC机制（六）在Android Studio中使用AIDL实现跨进程方法调用（补充）

一般来说AIDL 比较多的是机顶盒里面各个厂家apk 的相互调用，那么我们就来实现一个apk之间跨进程通讯的

在前面第三章 我们模拟了在同一个apk中不同进程中实现 。

服务端：在清单文件中把services加上action： <intent-filter> <action android:name="com.example.MyService"/> </intent-filter>

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.ywl5320.jnithread">

    <application
        android:name=".MyApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <service
            android:process=":secondprocess"
            android:name=".MyService"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.example.MyService"/>
            </intent-filter>

        </service>
    </application>

</manifest>

 

其余的aidl文件和class不变

 

客户的：

copyaidl文件夹到main目录下面

以及对应传输的class对象到Java包下面

此时build项目

然后新建一个aidl绑定的类

package com.amt.bsdiffpatch.utils;

import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.IBinder;

import com.ywl5320.jnithread.IGameManager;


/**
 */

public class AidlUtil {

    public IGameManager serviceCfg = null;
     Context mContext;

     public AidlUtil(Context mContext){
         this.mContext =mContext;
     }

    private ServiceConnection serviceConnection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
            serviceCfg = IGameManager.Stub.asInterface(iBinder);
        }

        @Override
        public void onServiceDisconnected(ComponentName componentName) {

            mContext.unbindService(serviceConnection);

        }
    };


    public boolean  bindIptvAidl() {

        try {
            Intent intent = new Intent();
            intent.setAction("com.example.MyService");
            boolean isSucess = mContext.bindService(intent,serviceConnection,mContext.BIND_AUTO_CREATE);
            System.out.println("chenzhu bindIptvAidl isSucess :"+isSucess);
            return isSucess;
        }catch(Exception e){
            System.out.println("chenzhu bindIptvAidl Exception :"+e.toString());
            return false;
        }

    }


}

 

在MainActivity中调用

public class MainActivity extends AppCompatActivity {
   Button mBtnPatch;

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


 final AidlUtil aidlUtil = new AidlUtil(this);
        System.out.println("------------>is success"+aidlUtil.bindIptvAidl());

        mBtnPatch = findViewById(R.id.id_btn_patch);
        mBtnPatch.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Game game =null;
                try {
                    game=aidlUtil.serviceCfg.getGameList().get(0);
                    System.out.println("========>"+game.gameDescribe);

                }catch(Exception e){

                }
                Toast.makeText(MainActivity.this,"=======>"+game.gameDescribe,Toast.LENGTH_LONG).show();



            }
        });
    }

   
}
注意aidl 绑定是耗时操作！！！
