在 Android 中啟用推播通知

推播通知可讓用戶在行動應用程式未在前景執行時，收到關於聊天線程中傳入訊息及其他操作的通知。 Azure 通訊服務支援您可以訂閱的事件清單。

備註

從 1.1.0-beta.4 和 1.1.0 開始，Android SDK 支援聊天推播通知。建議您使用 2.0.0 版或更新版本，因為舊版有註冊更新的已知問題。只有等於或大於 2.0.0 的版本才需要 8 到 12 的步驟。

設定 ChatQuickstart 專案的 Firebase 雲端通訊。完成 Firebase 檔中的步驟 Create a Firebase project、Register your app with Firebase、Add a Firebase configuration file、 Add Firebase SDKs to your app和 Edit your app manifest 。
在與通訊服務資源相同的訂用帳戶內建立通知中樞、設定中樞的 Firebase 雲端通訊設定，並將通知中樞連結至您的通訊服務資源。請參閱通知中樞布建。

請在MainActivity.java所在的目錄中新增一個名為MyFirebaseMessagingService.java的新檔案。將下列程式代碼複製到 MyFirebaseMessagingService.java。您必須將 <your_package_name> 替換為 MainActivity.java 中使用的套件名稱。您可以針對 <your_intent_name>使用自己的值。在步驟 6 中使用此值。

   package <your_package_name>;

   import android.content.Intent;
   import android.util.Log;

   import androidx.localbroadcastmanager.content.LocalBroadcastManager;

   import com.azure.android.communication.chat.models.ChatPushNotification;
   import com.google.firebase.messaging.FirebaseMessagingService;
   import com.google.firebase.messaging.RemoteMessage;

   import java.util.concurrent.Semaphore;

   public class MyFirebaseMessagingService extends FirebaseMessagingService {
       private static final String TAG = "MyFirebaseMsgService";
       public static Semaphore initCompleted = new Semaphore(1);

       @Override
       public void onMessageReceived(RemoteMessage remoteMessage) {
           try {
               Log.d(TAG, "Incoming push notification.");

               initCompleted.acquire();

               if (remoteMessage.getData().size() > 0) {
                   ChatPushNotification chatPushNotification =
                       new ChatPushNotification().setPayload(remoteMessage.getData());
                   sendPushNotificationToActivity(chatPushNotification);
               }

               initCompleted.release();
           } catch (InterruptedException e) {
               Log.e(TAG, "Error receiving push notification.");
           }
       }

       private void sendPushNotificationToActivity(ChatPushNotification chatPushNotification) {
           Log.d(TAG, "Passing push notification to Activity: " + chatPushNotification.getPayload());
           Intent intent = new Intent("<your_intent_name>");
           intent.putExtra("PushNotificationPayload", chatPushNotification);
           LocalBroadcastManager.getInstance(this).sendBroadcast(intent);
       }
   }

在檔案 MainActivity.java頂端，新增下列 import 語句：

   import android.content.BroadcastReceiver;
   import android.content.Context;
   import android.content.Intent;
   import android.content.IntentFilter;

   import androidx.localbroadcastmanager.content.LocalBroadcastManager;
   import com.azure.android.communication.chat.models.ChatPushNotification;
   import com.google.android.gms.tasks.OnCompleteListener;
   import com.google.android.gms.tasks.Task;
   import com.google.firebase.messaging.FirebaseMessaging;

將下列程式碼新增至 MainActivity 類別：

   private BroadcastReceiver firebaseMessagingReceiver = new BroadcastReceiver() {
       @Override
       public void onReceive(Context context, Intent intent) {
           ChatPushNotification pushNotification =
               (ChatPushNotification) intent.getParcelableExtra("PushNotificationPayload");

           Log.d(TAG, "Push Notification received in MainActivity: " + pushNotification.getPayload());

           boolean isHandled = chatAsyncClient.handlePushNotification(pushNotification);
           if (!isHandled) {
               Log.d(TAG, "No listener registered for incoming push notification!");
           }
       }
   };


   private void startFcmPushNotification() {
       FirebaseMessaging.getInstance().getToken()
           .addOnCompleteListener(new OnCompleteListener<String>() {
               @Override
               public void onComplete(@NonNull Task<String> task) {
                   if (!task.isSuccessful()) {
                       Log.w(TAG, "Fetching FCM registration token failed", task.getException());
                       return;
                   }

                   // Get new FCM registration token
                   String token = task.getResult();

                   // Log and toast
                   Log.d(TAG, "Fcm push token generated:" + token);
                   Toast.makeText(MainActivity.this, token, Toast.LENGTH_SHORT).show();

                   chatAsyncClient.startPushNotifications(token, new Consumer<Throwable>() {
                       @Override
                       public void accept(Throwable throwable) {
                           Log.w(TAG, "Registration failed for push notifications!", throwable);
                       }
                   });
               }
           });
   }

在MainActivity中更新函式onCreate。

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

       LocalBroadcastManager
           .getInstance(this)
           .registerReceiver(
               firebaseMessagingReceiver,
               new IntentFilter("<your_intent_name>"));
   }

將下列程式代碼放在MainActivity中的註解<RECEIVE CHAT MESSAGES>之後：

   startFcmPushNotification();

   chatAsyncClient.addPushNotificationHandler(CHAT_MESSAGE_RECEIVED, (ChatEvent payload) -> {
       Log.i(TAG, "Push Notification CHAT_MESSAGE_RECEIVED.");
       ChatMessageReceivedEvent event = (ChatMessageReceivedEvent) payload;
       // You code to handle ChatMessageReceived event
   });

將 xmlns:tools 欄位新增至 AndroidManifest.xml 檔案：

    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    package="com.azure.android.communication.chat.sampleapp">

在 AndroidManifest.xml 中停用 WorkManager 的預設初始化器：

    <!-- Disable the default initializer of WorkManager so that we could override it in MyAppConfiguration  -->
    <provider
        android:name="androidx.startup.InitializationProvider"
        android:authorities="${applicationId}.androidx-startup"
        android:exported="false"
        tools:node="merge">
      <!-- If you are using androidx.startup to initialize other components -->
      <meta-data
          android:name="androidx.work.WorkManagerInitializer"
          android:value="androidx.startup"
          tools:node="remove" />
    </provider>
    <!-- End of Disabling default initializer of WorkManager -->

將 WorkManager 相依性新增至您的 build.gradle 檔案：

    def work_version = "2.7.1"
    implementation "androidx.work:work-runtime:$work_version"

藉由建立一個實作Configuration.Provider的類別來新增自訂WorkManager初始化子：

    public class MyAppConfiguration extends Application implements Configuration.Provider {
        Consumer<Throwable> exceptionHandler = new Consumer<Throwable>() {
            @Override
            public void accept(Throwable throwable) {
                Log.i("YOUR_TAG", "Registration failed for push notifications!" + throwable.getMessage());
            }
        };
    
        @Override
        public void onCreate() {
            super.onCreate();
            // Initialize application parameters here
            WorkManager.initialize(getApplicationContext(), getWorkManagerConfiguration());
        }
    
        @NonNull
        @Override
        public Configuration getWorkManagerConfiguration() {
            return new Configuration.Builder().
                setWorkerFactory(new RegistrationRenewalWorkerFactory(COMMUNICATION_TOKEN_CREDENTIAL, exceptionHandler)).build();
        }
    }

上述程式代碼的說明：在步驟 9 中停用的預設初始化表達式WorkManager。此步驟會實作 Configuration.Provider 以提供自定義的 WorkFactory，負責在運行時建立 WorkerManager。

如果應用程式與 Azure Function 整合，請在方法 onCreate()中初始化應用程式參數。在啟動應用程式時，會在建立任何活動、服務或接收者物件之前呼叫方法 getWorkManagerConfiguration() （不包括內容提供者），因此可以在使用之前先初始化應用程式參數。如需詳細資訊，請參閱範例聊天應用程式。

將 android:name=.MyAppConfiguration 使用步驟 11 類別名稱的欄位新增至 AndroidManifest.xml：

<application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:theme="@style/Theme.AppCompat"
      android:supportsRtl="true"
      android:name=".MyAppConfiguration"
