先上git的地址

https://gitee.com/wanghong_wahaha/AidlDemo.git

前言：之前在網(wǎng)上找過一些博客學(xué)習(xí)AIDL屯吊，但是很多只有介紹凌彬，但是沒有demo可供參考，或者干脆就做在了一個(gè)APP里面,達(dá)不到兩個(gè)APP間通信的要求收夸，所以就自己整理一下。

1.創(chuàng)建服務(wù)端的app,新建aidl文件,點(diǎn)擊編譯按鈕（如果不編譯會(huì)找不到定義接口生成的Stub抽象類）

    public class MyService extends Service {
    
        @Nullable
        @Override
        public IBinder onBind(Intent intent) {
            return new IBinderImp(){
                @Override
                public String str(String str) throws RemoteException {
                    Log.d("MyService",str);
    
                    return super.str(str);
                }
            };
        }      
    }

    public class IBinderImp extends My_Service_Int.Stub {
    
        @Override
        public String str(String str) throws RemoteException {
            return str;
        }
    }

    //注意 android:exported="true" 砚哆，不然外部無法訪問到
    <service
        android:name=".MyService"
        android:enabled="true"
        android:process=":AidlService"
        android:exported="true">
        <intent-filter>
            <action android:name="com.example.kong.myapplication.MyServer" />
        </intent-filter>

    </service>

3.新建另一個(gè)module（客戶端）,拷貝main目錄下的整個(gè)AIDL文件夾到此module下，老規(guī)矩，編譯躁锁，然后編寫代碼綁定服務(wù)端的Service纷铣，需要設(shè)定其action和application的包名

    class MainActivity : AppCompatActivity() {
    
        lateinit var my_service_int: My_Service_Int
        lateinit var connection: ServiceConnection
    
        override fun onCreate(savedInstanceState: Bundle?) {
            super.onCreate(savedInstanceState)
            setContentView(R.layout.activity_main)
    
    
            val intents = Intent("com.example.kong.myapplication.MyServer")
            intents.setPackage("com.example.kong.myapplication")
    //        intents.component = ComponentName("com.example.kong.myapplication", "com.example.kong.myapplication.MyServer")
            connection = object : ServiceConnection {
                override fun onServiceConnected(name: ComponentName, service: IBinder) {
    
                    Log.d("MainActivity", "鏈接上了")
                    //AIDL接口調(diào)用asInterface(Binder) 獲取到接口對象
    
                    my_service_int = My_Service_Int.Stub.asInterface(service)
    
                }
    
                override fun onServiceDisconnected(name: ComponentName) {
    
                }
            }
    
            bindService(intents, connection, BIND_AUTO_CREATE)
    
    
        }
    
        override fun onDestroy() {
            super.onDestroy()
            unbindService(connection)
        }
    
        fun sendMessage(v: View) {
            try { //調(diào)用接口中的方法，為其賦值
                my_service_int.str("新聞聯(lián)播")
            } catch (e: RemoteException) {
                e.printStackTrace()
            }
    
        }
    }

接下來就測試服務(wù)有沒有收到消息战转，我點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)點(diǎn)....
