【问题描述】：

我正在使用自定义声音在本地安排通知，但未播放自定义声音。事实上，没有显示通知警报。即使在 setNotificationsHandler 中将 show alert 和 shouldPlaySound 设置为 true。还应该提到的是，即使我在 app.json 的 expo-notifications 插件以及通知通道和通知内容输入中添加了自定义颜色，颜色也保持不变。

我检查了安装 apk 的设备的通知设置。存在通知频道，并且该频道的默认铃声也设置为自定义声音。但是它只是在通知到来时不播放。

相关代码：

import { StatusBar } from "expo-status-bar";
import React from "react";
import { Text, View, Platform, Button } from "react-native";
import * as Notifications from "expo-notifications";

Notifications.setNotificationHandler({
  handleNotification: async () => ({
    shouldShowAlert: true,
    shouldPlaySound: true,
    shouldSetBadge: false,
  }),
});

export default function App() {
  React.useEffect(() => {
    setNotificationChannelAsync();
  }, []);

  return (
    <View
      style={{
        flex: 1,
        alignItems: "center",
        justifyContent: "space-around",
      }}
    >
      <Text>This App is for Testing Notifications</Text>
      <Button
        title="Press to schedule a notification"
        onPress={async () => {
          await scheduleNotification();
        }}
      />
      <StatusBar style="auto" />
    </View>
  );
}

const setNotificationChannelAsync = () => {
  if (Platform.OS === "android") {
    Notifications.setNotificationChannelAsync("sound", {
      name: "sound notification",
      importance: Notifications.AndroidImportance.HIGH,
      vibrationPattern: [0, 250, 250, 250],
      lightColor: "#FF231F7C",
      sound: "adhan.wav",
    });
  }
};

async function scheduleNotification() {
  await Notifications.scheduleNotificationAsync({
    content: {
      title: "You've got mail! ????",
      body: "Here is the notification body",
      data: { data: "goes here" },
      sound: "adhan.wav",
      color: "#FF231F7C",
    },
    trigger: { seconds: 5, channelId: "sound" },
  });
}

【解决方案1】：

我认为这是因为默认通知渠道。我删除了所有频道。使用新的频道标识符设置新的新频道并开始工作。
