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。

 1      mBinding.btnBinderAidl.setOnClickListener(new View.OnClickListener() {
 2             @Override
 3             public void onClick(View v) {
 4                 try {
 5                     Intent intent = new Intent();
 6                     intent.setAction("com.great.android.server.action");
 7                     intent.setPackage("com.great.android.server");
 8                     bindService(intent, connection, BIND_AUTO_CREATE);
 9                 } catch (Exception e) {
10                     e.printStackTrace();
11                 }
12             }
13     });
14 　　
15     private IMyAidlInterface myService;
16     public ServiceConnection connection = new ServiceConnection() {
17         @Override
18         public void onServiceConnected(ComponentName name, IBinder service) {
19             myService = IMyAidlInterface.Stub.asInterface(service);
20             try {
21                 Toast.makeText(MainActivity.this, myService.getString(), Toast.LENGTH_SHORT).show();
22                 Log.d(TAG, myService.getString());
23                 System.out.println("=============================");
24 
25                 unbindService(connection);
26                 if (myService != null) {
27                     myService = null;
28                 }
29             } catch (RemoteException e) {
30                 e.printStackTrace();
31             }
32 
33             Log.d(TAG, "onServiceConnected:");
34         }
35 
36         @Override
37         public void onServiceDisconnected(ComponentName name) {
38             Log.d(TAG, "onServiceDisconnected:");
39             myService = null;
40         }
41     };
42 
43     /**
44      * 解绑服务
45      */
46     @Override
47     protected void onDestroy() {
48         super.onDestroy();
49         unbindService(connection);
50         if (myService != null) {
51             myService = null;
52         }
53     }

2.在AndroidManifest.xml中添加如下权限：

1     <uses-permission
2         android:name="android.permission.QUERY_ALL_PACKAGES"
3         tools:ignore="QueryAllPackagesPermission" />
4 
5     <queries>
6         <package android:name="com.great.android.server" />
7     </queries>

Server（服务端）：

 

 1 /**
 2  * 这个Service是一个独立进程
 3  */
 4 public class MyService extends Service {
 5     private String TAG = MyService.class.getSimpleName();
 6 
 7     @Override
 8     public IBinder onBind(Intent intent) {
 9         Log.d(TAG, "onBind: ");
10         return new MyBind();
11     }
12 
13     @Override
14     public void onCreate() {
15         super.onCreate();
16         Log.d(TAG, "create: " + Thread.currentThread().getName());
17     }
18 
19     @Override
20     public int onStartCommand(Intent intent, int flags, int startId) {
21         Log.d(TAG, "onStartCommand: ");
22         return super.onStartCommand(intent, flags, startId);
23     }
24 
25     @Override
26     public void onDestroy() {
27         super.onDestroy();
28         Log.d(TAG, "onDestroy: ");
29     }
30 
31     public class MyBind extends IMyAidlInterface.Stub {
32 
33         @Override
34         public void notifiy() throws RemoteException {
35             try {
36                 Thread.sleep(500);
37             } catch (Exception e) {
38                 e.printStackTrace();
39             }
40             Log.d(TAG, "notify sleep: ");
41         }
42 
43         @Override
44         public String getString() throws RemoteException {
45             try {
46                 Thread.sleep(500);
47             } catch (Exception e) {
48                 e.printStackTrace();
49             }
50             Log.d(TAG, "getString: " + Thread.currentThread().getName());
51             return "hello this is service";
52         }
53     }
54 }

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！
