Expo notifications not working when channel id is used

Question

I am using the following code to create two channels for my expo react app, on Android:

Notifications.setNotificationChannelAsync("default", {
            name: "default",
            importance: Notifications.AndroidImportance.MAX,
            vibrationPattern: [0, 250, 250, 250],
            lightColor: "#FF231F7C",
        })  

Notifications.setNotificationChannelAsync("gameupdates", {
                name: "gameupdates",
                importance: Notifications.AndroidImportance.MAX,
                vibrationPattern: [0, 250, 250, 250],
                lightColor: "#FF231F7C",
            })

The channel is successfully created and I can even find it when I go into the Expo app notification options.

When I send a notification using expo's tool without any channel id, it works fine. However, when I use the channel id "gameupdates", the notification never reaches my phone.

Any idea why?

I am on the expo sdk 38.

Answer 1

Fixed it! The issues was that I needed to add android.useNextNotificationsApi: true to the app.json. Then I had to do expo:build and manually upload the build.

Answer 2

You have created your channel successfully but doesn't updated your app's expo notifications settings. For this you must add -

android: {
...
"useNextNotificationsApi": true
}

in your app.json file.

Then just run your code by clearing expo cache like -

expo start -c

And test it! You will start receiving the notifications on your Android 10+ mobiles also.
