How to play custom notification sounds on EAS built Android app?

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": [
          "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';

    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 => {

        // 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 => {

        return () => {
    }, []);

                onPress={async () => {
                    await sendPushNotification(expoPushToken);

// Can use this function below, OR use Expo's Push Notification Tool->
async function sendPushNotification(expoPushToken) {
// Instead of using expo push notification server, using FCM Server here:
     const message = {
       to: expoPushToken,
       sound: 'default',

            finalStatus = status;
        if (finalStatus !== 'granted') {
            alert('Failed to get push token for push notification!');
        // token = (await Notifications.getExpoPushTokenAsync()).data;
        // Since only FCM support custom sound, we have to change this to get device token here.
        token = (await Notifications.getDevicePushTokenAsync()).data;
    } else {
        alert('Must use physical device for Push Notifications');

    if (Platform.OS === 'android') {
        Notifications.setNotificationChannelAsync('default', {
            name: 'default',
            importance: Notifications.AndroidImportance.MAX,
            vibrationPattern: [0, 250, 250, 250],
            lightColor: '#FF231F7C',

    return token;


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
