QUESTION
I am using firebase messaging to send notifications to users in flutter application, and everything is working fine when I am sending notification from postman (notification always shows), but then when I want to send the same notification from my backend server, notification not showing on device. On server logs I can see that notification was send with success like this:
...ANSWER
Answered 2022-Mar-03 at 10:44As per your data send with fcm is sending only data object not notification object as per the fcm to wakeup it self you need to send notification object along with data object.

QUESTION
I am receiving messages from firebase for notifications with APNs. In firebase, I have the certificate of APNs key, with the same id in the Xcode project in Firebase that is extracted from Apple Developer.
But I don't know why this could be happening and I get this error and it is registering two tokens in the Messaging extension:
...ANSWER
Answered 2021-Oct-26 at 05:58This is a simulator only log. You can safely ignore it. The reason you get this is that Firebase tries to create a mapping from the FCM token to the APNS token so it can send the APNS messages to the iOS devices. However, there is no APNS token on the simulator so the mapping fails.
Try testing it on an actual device to see if you still get the error.
QUESTION
The FCM documentation says that one should use device groups to send to ALL of a user's devices. The API for it, though, is still a legacy API, and I can't get it to work.
I am using code like the following, where project_id
is the sender ID and api_key
is the Web API Key from the firebase console:
ANSWER
Answered 2022-Feb-09 at 20:37Ok, the "key" is the "server key" from the cloud messaging tab, and the "project_id" is the "Sender ID" from the same.
That seems to have solved it for me.

QUESTION
I am using Agora for a one-to-one video chat purpose in Flutter. User1 has an app to go online and user2 has another app to go online. After both of them go online, they can do video chat with one another. Both apps have almost similar codebase.
I have a screen or activity (say screen1) where an alert dialog is shown on tapping a button (say button1). On tapping the Continue
button in the alert dialog, the dialog disappears and the user is taken to the screen (say screen2) where the video chat takes place. But after going to the video chat screen successfully, if the user taps on the back button on the mobile set then s/he is taken to screen1 and after tapping on button1, if the user taps on the Continue
button in the popped up alert dialog, the user is again taken to screen2 but this time the local video (i.e. video of the user using the app) keeps loading for ever. Obviously I want the local video to load as it did for the first time.
I am gonna put my code here in such a way that you can easily run that.
Following code is for user1. For user2, no alert box is there in the app. Same code from user1 is used for user2 app, except the value of remoteUid
is set to be 2 for user2 while this value is set to be 1 for user1. These are just two values identifying 2 users.
For user1:

is not being end. You can try by leaving

QUESTION
Preface:
My App is Flutter based - but native code implementation is required to get FCM messages working, see below for more details
GitHub issue #154 for reference.
I'm having immense trouble getting FCM notifications working on iOS, specifically on my app published to Testflight. I have been stuck on this problem for a week and have absolutely no idea how to proceed.
Problem
When running locally using debug/release builds on my devices using Xcode/Android Studio, notifications are received in the background, foreground, etc. When uploading the exact same app to Testflight, not a single notification will come through via FCM.
This is crucial as FCM delivers VoIP notifications, these aren't being received on Testflight which is extremely distressing
Questions & Solutions?
There are 2 questions I found (here & here), both seemed to indicate it is a APNS certificate problem (APNS -> Firebase). I have recreated my certificate and added it to the Firebase console (using the same .csr
file for all certificate generating operations)
Setup/Configuration:
APNS Key generated & added to Firebase
Capabilities:
Tried with:
...ANSWER
Answered 2021-Oct-16 at 20:45This problem sometimes drive people crazy even they apply everything in the correct scenario, so please try to check the following:
1- in your apple developer account make sure that you have only one Apple Push Services Certificate
assigned to the app identifier ( Bundle ID ), please avoid duplication.
2- If you are using the APNs key to receive notification you have to make sure its set on the production mode when your app is uploaded to TestFlight or AppStore
QUESTION
A project I'm working on requires the use of FCM Push Notifications & Messages for VoIP control amongst others.
Problem:
My iOS physical device receives push notifications, but only when the app is in the background or closed but NOT when in the foreground. Further, it does NOT receive any fcm message (data) notifications at all such as messages with only data and no notification title/body i.e. VoIP status message.
My setup steps are as follows (a detailed setup and general flow I followed can be found here):
Register a (
Info.plist
) (see here)Download & install
GoogleService-Info.plist
with Xcode (see here)Create APNS key with enabled Push Notifications and uploaded
.p8
file to Firebase (see here)Modify with Swift code:

ANSWER
Answered 2021-Sep-16 at 07:09FCM does not work on the iOS simulator, so thats half the question solved. For physical devices, take a look at some debugging steps I wrote in detail on a library I work on.
There are multiple ways push notification can go wrong on iOS. When you say: the app never receives
, do you mean your Flutter application doesn't get the message? Your device could still be receiving them.
- Open
Console.app
on your mac, and start the logging for your physical device. Filter fordasd
process, and you can see push notification related logs to see if your device rejected the push notification and did not send it to your app. Most likely, its a problem with how you structured your message. - You can also try to debug the
didReceiveRemoteNotification
method on the iOS side inside the Flutterfire firebase_messaging iOS code. That would mean the message is received by the app.
- My iOS physical device receives push notifications, but only when the app is in the background or closed but NOT when in the foreground.
So you want to show notifications in the foreground? You need to implement userNotificationCenter(_:willPresent:withCompletionHandler:)
, for example, in Swift:
QUESTION
My app starts with a simple html form. the inputs are PIN# and Date Of Birth.
My express server runs on the same port 3000, when the user submits their data, puppeteer starts and logs into a specific webpage. Then I scrape the image on that webpage. Google Api takes the text from that image and saves it in an array. I then post that array string to src/results.html. But as soon as the user hits submit, they are redirected to /resuts route right immediately and the page says cannot post the data. but when I see in the console (roughly a minute later) that the post was successful, I refresh the page and I get the array of text I wanted to see.
How can I await for the data to finish being posted to the route before the page loads the data? Im using react for client side. below is my server side code. client side is just a basic react page login and a static /results page meant for the data.
...ANSWER
Answered 2021-Aug-31 at 05:43I think I got the problem.
In the react
app, maybe you are not using e.preventDefault()
when you click submit. The browser, by default, redirects to a page where the form action is directing, if the action attribute is empty then the browser reloads the same page. I would recommend you to use e.preventDefault()
on form submission and then use fetch
API to make the request.
In the express
server, on the route POST "results", you are not sending any response back to the user. You should always send a response to the user. In your case you are calling the App
function - which has many async functions, but you are not awaiting for App()
to complete in the POST route, express is sending default response to the user as soon as it parses App()
- it is not waiting for the App()
to complete - express will get to this later.
You can make the (req, res) => { ... }
function in the route as async
function async (req, res) => { ... }
, then you can make the App
as async function as well. Then you can await App(...)
in the route function. Also, you need to await for the main()
function as well inside the App()
function. Then once App()
call has finished, you can send redirect response to the user.
QUESTION
I am trying to measure the number of times that different words co-occur with a particular term in collections of Chinese newspaper articles from each quarter of a year. To do this, I have been using Quanteda and written several R functions to run on each group of articles. My work steps are:
- Group the articles by quarter.
- Produce a frequency co-occurence matrix (FCM) for the articles in each quarter (Function 1).
- Take the column from this matrix for the 'term' I am interested in and convert this to a data.frame (Function 2)
- Merge the data.frames for each quarter together, then produce a large csv file with a column for each quarter and a row for each co-occurring term.
This seems to work okay. But I wondered if anybody more skilled in R might be able to check what I am doing is correct, or might suggest a more efficient way of doing it?
Thanks for any help!
...ANSWER
Answered 2021-Aug-13 at 09:28If you are interested in counting co-occurrences within a window for specific target terms, a better way is to use the window
argument of tokens_select()
, and then to count occurrences from a dfm on the window-selected tokens.

Install fcm
Tip: every time you change a native code you may need to clean up the cache (Product > Clean build folder) and then run the app again.
sudo gem install cocoapods (once a time)
ionic start my-cap-app --capacitor
cd my-cap-app
mkdir www && touch www/index.html
npx cap add ios
npm install --save @capacitor-community/fcm
npx cap sync ios (always do sync after a plugin install)
npx cap open ios
sign your app at xcode (general tab)
enable remote notification capabilities
add GoogleService-Info.plist to the app folder in xcode
on your MainActivity.java file add import com.getcapacitor.community.fcm.FCMPlugin; and then inside the init callback add(FCMPlugin.class);. Now you should be set to go. Try to run your client using ionic cap run android --livereload.
