Question

如果我對用戶是否希望啓用通知有所偏好。我應該發送哪個事件，以便在發送通知時排除此用戶？

Answer 1

在onMessageReceived方法中，如果在SharedPReferences中有通知（bool）= true，請嘗試驗證。

@Override 
public void onMessageReceived(RemoteMessage remoteMessage) { 
// ... 



// TODO(developer): Handle FCM messages here. 
// Not getting messages here? See why this may be 
Log.d(TAG, "From: " + remoteMessage.getFrom()); 

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

// Check if message contains a notification payload. 
if (remoteMessage.getNotification() != null) { 
    Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody()); 
} 

// Also if you intend on generating your own notifications as a result of a received FCM 
// message, here is where that should be initiated. See sendNotification method below. 
}
