Android AIDL的使用

Client（客户端）:

 

1.客户端的aidl必须和服务端的aidl的包名、文件名必须一致。

     mBinding.btnBinderAidl.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                try {
                    Intent intent = new Intent();
                    intent.setAction("com.great.android.server.action");
                    intent.setPackage("com.great.android.server");
                    bindService(intent, connection, BIND_AUTO_CREATE);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }
    });
　　
    private IMyAidlInterface myService;
    public ServiceConnection connection = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName name, IBinder service) {
            myService = IMyAidlInterface.Stub.asInterface(service);
            try {
                Toast.makeText(MainActivity.this, myService.getString(), Toast.LENGTH_SHORT).show();
                Log.d(TAG, myService.getString());
                System.out.println("=============================");

                unbindService(connection);
                if (myService != null) {
                    myService = null;
                }
            } catch (RemoteException e) {
                e.printStackTrace();
            }

            Log.d(TAG, "onServiceConnected:");
        }

        @Override
        public void onServiceDisconnected(ComponentName name) {
            Log.d(TAG, "onServiceDisconnected:");
            myService = null;
        }
    };

    /**
     * 解绑服务
     */
    @Override
    protected void onDestroy() {
        super.onDestroy();
        unbindService(connection);
        if (myService != null) {
            myService = null;
        }
    }

2.在AndroidManifest.xml中添加如下权限：

    <uses-permission
        android:name="android.permission.QUERY_ALL_PACKAGES"
        tools:ignore="QueryAllPackagesPermission" />

    <queries>
        <package android:name="com.great.android.server" />
    </queries>

Server（服务端）：

 

/**
 * 这个Service是一个独立进程
 */
public class MyService extends Service {
    private String TAG = MyService.class.getSimpleName();

    @Override
    public IBinder onBind(Intent intent) {
        Log.d(TAG, "onBind: ");
        return new MyBind();
    }

    @Override
    public void onCreate() {
        super.onCreate();
        Log.d(TAG, "create: " + Thread.currentThread().getName());
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        Log.d(TAG, "onStartCommand: ");
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        Log.d(TAG, "onDestroy: ");
    }

    public class MyBind extends IMyAidlInterface.Stub {

        @Override
        public void notifiy() throws RemoteException {
            try {
                Thread.sleep(500);
            } catch (Exception e) {
                e.printStackTrace();
            }
            Log.d(TAG, "notify sleep: ");
        }

        @Override
        public String getString() throws RemoteException {
            try {
                Thread.sleep(500);
            } catch (Exception e) {
                e.printStackTrace();
            }
            Log.d(TAG, "getString: " + Thread.currentThread().getName());
            return "hello this is service";
        }
    }
}

AndroidManifest.xml权限文件

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

    <uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/logo"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/Theme.BaseImproveStudy">

        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

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

        <service
            android:name=".MyService"
            android:enabled="true"
            android:exported="true">
            <intent-filter>
                <action android:name="com.great.android.server.action" />
            </intent-filter>
        </service>
    </application>

</manifest>

最后：运行服务端，再调用客户端！
