How do I use Firebase cloud messaging to receive push notifications

mazenkh7 commented 5 years ago

In Android, Java; Since FCM, should be same as GCM I did the following after i created a Client object:

FirebaseInstanceId.getInstance().getInstanceId() .addOnCompleteListener(new OnCompleteListener() { @Override public void onComplete(@NonNull Task task) { if (!task.isSuccessful()) { return; } // Get new Instance ID token from Firebase token = task.getResult().getToken(); if (getToken() != null && !getToken().isEmpty()) client.send(new TdApi.RegisterDevice(new TdApi.DeviceTokenGoogleCloudMessaging(getToken()), null), null); } });

the token is registered successfully but i get no notifications at all, the function (onMessageReceived) doesn't get called.

is there anything else i should do? (i actually don't know what 'otherUserIDs' is and how to use it)

You have not passed a handler to the RegisterDevice request, so you don't really know whether request has succeded or returned an error.

First of all, you need to register your app at https://my.telegram.org, obtaining api_id and api_hash, choose app's operating system as Android and then upload FCM certificates for your app.

Between, in TDLib 1.4.0 DeviceTokenGoogleCloudMessaging was renamed to DeviceTokenFirebaseCloudMessaging and full push notification handling was implemented in TDLib. See https://core.telegram.org/tdlib/notification-api for more details.

Thanks a lot, I will update tdlib. But there still is a problem, I registered my app before in my.telegram.org There's no where to select the operating system as android also there's no where to upload said fcm certificates. And I can't delete my app nor create new one IMG_20190508_152617

@mazenkh7 You have already chosen right operating system. The only thing you need to do is to upload FCM API key in the "GCM API key" section.

mazenkh7 commented 5 years ago

Thanks a lot for your help, now after I did all that, I receive a "pushReceiver ID" from the registerDevice function, but that's all no notifications are received (onMessageReceived from the my FirebaseMessagingService is never called) or is this normal behavior and I should find the notifications elsewhere? I read this https://core.telegram.org/tdlib/notification-api but i didn't quite understand where the PUSH notifications are received. thanks.

(Also if there is a minimum working example for notifications, like the java example that would be great as I learned a lot from it)

To use TDLib Notification API you need to receive push notification as usually, then convert notification payload to JSON similar to examples in https://core.telegram.org/tdlib/notification-api#handling-push-notifications and pass it to ProcessPushNotification.

If you don't receive notifications through FirebaseMessagingService.onMessageReceived you need to recheck that server has accepted your GCM API key, that you use your API ID in the app and that you pass correct token to registerDevice. If this doesn't help please write API ID, user_id and other details to @tdlib_bot.

Thanks its showing successfully now, you're helpful and patient! The bot is amazing too.

I have another question though, why do i receive pending messages / delayed notifications? and what should I do if I know that I have delayed notifications.

levlam commented 5 years ago

If the user is offline, notifications are delayed in order to give him a chance to read the messages from a different device before the notification is shown.

@levlam I don't see this section in my.telegram.org anymore. Is it still possible to register FCM certs?

Edit: We're developing on web.

MattNguyen commented 5 years ago

Looks like the push-notification option appears when you select android, not web. Is there a way to change the platform or revoke the api key/hash?

levlam commented 5 years ago

@MattNguyen FCM certificates is possible to register only if you are developing for Android and have chosen Android as operating system for your application. There is no way to change chosen platform after application is created.

Hi. I have already registered the device on Firebase, Telegram, have all. I run. Receive correctly the receiver id. So, my question is: Whats next? Because in the documentation say that have to enter on updateActiveNotifications and is not doing that. What i have to do,once i have the receiver ID?

levlam commented 4 years ago

ReceiverId is needed to launch correct TDLib instance with the same receiverId received from registerDevice. If you have only one account, then you don't need to use receiverId at all.

ljmartinez1994 commented 4 years ago

Accounts? Do you refer to user telegram account? I don undestand to you very well. Even is that, Tdlib is entering on some status, the user have pending notifications and tdlib do nothing.

@ljmartinez1994 Send logs with verbosity level 4 to @tdlib_bot.

recheck that server has accepted your GCM API key

@levlam Hi, how can i check that the server has accepted my GCM API key?

levlam commented 3 years ago

@bantonen If you didn't receive an error while uploading the certificate at my.telegram.org, then it was accepted,

bantonen commented 3 years ago

@levlam but if I am using Android, as I understand it, I do not need a certificate, right?

levlam commented 3 years ago

@bantonen You need to upload a valid API key from console.cloud.google.com for your api ID at my.telegram.org. Otherwise, Telegram will not be able to send push notifications to your app.

bantonen commented 3 years ago

@levlam You mean these api keys https://firebase.google.com/docs/projects/api-keys#create-api-keys ?

levlam commented 3 years ago

@bantonen On this page there is a link to https://console.cloud.google.com/apis/credentials.

bantonen commented 3 years ago

@levlam I am loading this api key but no notifications are coming. Can you please tell me what the problem might be. My app id (492896)

levlam commented 3 years ago

@bantonen You also need to write your user_id to @tdlib_bot.

king-ma1993 commented 4 months ago

@levlam How can I know if the API key I set is correct? After setting it, I still don't receive notifications. I'm looking forward to your reply.
