I am new to expo and react native. I want to make a demo android app which can play custom notification sounds on receive FCM notification using EAS.
But this demo doesn’t work, I can’t find the reason,
The complete code is on the Github woohelps/expo-custom-notification-sounds.git
##Here are the details of this demo:
- expo
init expo-custom-notification-sounds
(choose blank template) - run
expo install expo-notifications
under root of project - According [the document] add the expo-notifications plugin to your app.json file as below:
"expo": {
"plugins": [
[
"expo-notifications",
{
"sounds": ["./assets/mySoundFile.wav"]
}
]
]
}
}
- According [this], I need to set up [Using FCM for Push Notifications]
In my app.json, add an android.googleServicesFile field with the relative path to the google-services.json which I created in the firebase console.
{
...
"android": {
"googleServicesFile": "./google-services.json",
...
}
}
- Confirm that my API key in google-services.json has the correct “API restrictions” in the Google Cloud Platform API Credentials console.
- According [this] run
expo prebuild
. create android native folders - Add [Demo] code in the App.js
import Constants from 'expo-constants';
import * as Notifications from 'expo-notifications';
import React, {useState, useEffect, useRef} from 'react';
import {Text, View, Button, Platform} from 'react-native';
Notifications.setNotificationHandler({
handleNotification: async () => ({
shouldShowAlert: true,
shouldPlaySound: true, // change false to true
shouldSetBadge: false,
}),
});
export default function App() {
const [expoPushToken, setExpoPushToken] = useState('');
const [notification, setNotification] = useState(false);
const notificationListener = useRef();
const responseListener = useRef();
useEffect(() => {
registerForPushNotificationsAsync().then(token => setExpoPushToken(token));
// This listener is fired whenever a notification is received while the app is foregrounded
notificationListener.current = Notifications.addNotificationReceivedListener(notification => {
setNotification(notification);
});
// This listener is fired whenever a user taps on or interacts with a notification (works when app is foregrounded, backgrounded, or killed)
responseListener.current = Notifications.addNotificationResponseReceivedListener(response => {
console.log(response);
});
return () => {
Notifications.removeNotificationSubscription(notificationListener.current);
Notifications.removeNotificationSubscription(responseListener.current);
};
}, []);

Updated:
Refer to this Custom notification sounds doesn’t work on EAS built app.:
and Updated the Channel code, then try to run expo run:android
, but return BUILD FAILED
