Firebase通知不會出現在我的設備上

Question

我按照Google文檔中的說明實施了Firebase。我從Firebase控制檯發送消息。但通知不會出現在我的設備上。你可以幫我嗎？先謝謝你。

在我的`AndroidManifest.xml中

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.WAKE_LOCK" /> 
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 

<permission 
    android:name="android.permission.INTERACT_ACROSS_USERS_FULL" 
    android:protectionLevel="signature" /> 

<application 
    android:allowBackup="true" 
    android:icon="@mipmap/ic_launcher" 
    android:label="@string/app_name" 
    android:supportsRtl="true" 
    android:theme="@style/AppTheme"> 
    <activity 
     android:name=".another.IntroActivity" 
     android:theme="@style/AppTheme.NoActionBar" 
     android:screenOrientation="portrait"> 
     <intent-filter> 
      <action android:name="android.intent.action.MAIN" /> 

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

    <service android:name=".firebase.MyFirebaseInstanceIdService"> 
     <intent-filter> 
      <action android:name="com.google.firebase.INSTANCE_ID_EVENT" /> 
     </intent-filter> 
    </service> 
    <service android:name=".firebase.MyFirebaseMessagingService"> 
     <intent-filter> 
      <action android:name="com.google.firebase.MESSAGING_EVENT" /> 
     </intent-filter> 
    </service> 
</application> 

在MyFirebaseInstanceIdService.java

public class MyFirebaseInstanceIdService extends FirebaseInstanceIdService { 
private static final String TAG = "FBIIS"; 

@Override 
public void onTokenRefresh() { 
    String refreshedToken = FirebaseInstanceId.getInstance().getToken(); 
    Log.d(TAG, "Refreshed token: " + refreshedToken); 

} 
} 

在MyFirebaseMessagingService.java

public class MyFirebaseMessagingService extends FirebaseMessagingService { 
private String TAG = "MFMS"; 

@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
    super.onMessageReceived(remoteMessage); 

    Map<String, String> newMsg = remoteMessage.getData(); 

    Set<String> keys = newMsg.keySet(); 
    Iterator<String> iterator = keys.iterator(); 

    while (iterator.hasNext()) { 
     String key = iterator.next(); 

     Log.e(TAG, "key = " + key + " value = " + newMsg.get(key)); 
    } 


    Log.d(TAG, "From: " + remoteMessage.getFrom()); 


    if (remoteMessage.getData().size() > 0) { 
     Log.d(TAG, "Message data payload: " + remoteMessage.getData()); 
    } 


    if (remoteMessage.getNotification() != null) { 
     Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody()); 
    } 
} 
} 

我的應用程序不進入onMessageReceived函數。我不知道爲什麼......

Answer 1

在MyFirebaseMessagingService類創建通知時所收到的消息：

sendNotification("Hello","FCM"); 

//method 

     private void sendNotification(String messageTitle, String messageBody) { 
       Intent intent = new Intent(this, SplashActivity.class); 
       intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP); 
       PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_ONE_SHOT); 

       Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION); 
       NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this) 
         .setSmallIcon(R.mipmap.ic_launcher) 
         .setContentTitle(!Utils.isStringNullOrEmpty(messageTitle) ? messageTitle : APP.NAME) 
         .setContentText(messageBody) 
         .setAutoCancel(true) 
         .setSound(defaultSoundUri) 
         .setStyle(new NotificationCompat.BigTextStyle().bigText(messageBody)) 

         .setContentIntent(pendingIntent); 
       NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE); 
       notificationManager.notify(1, notificationBuilder.build()); 
    } 

Answer 2

在 onTokenRefresh()添加 sendRegistrationToServer(refreshedToken)

，並實現這一點。
