背景提取在独立应用程序中不起作用

如何解决背景提取在独立应用程序中不起作用

我已经解决了在 Expo-GO 中完美运行的后台功能，但是在传输 apk 时，它在独立应用程序中根本不工作

该功能正在执行，假设按照之前的预定时间在特定时间向用户发送本地通知

如果有人可以的话，需要一些帮助

import React,{ useEffect,useState } from 'react';
import {
    View,Text,StyleSheet
} from 'react-native';
import * as BackgroundFetch from 'expo-background-fetch';
import * as TaskManager from 'expo-task-manager';
import * as Notifications from 'expo-notifications';
import { data } from '../helpers/timeData';




const ALARM_TASK_FETCH = 'alarm_task_fetch';

TaskManager.defineTask(ALARM_TASK_FETCH,() => {
    Notifications.cancelAllSchedulednotificationsAsync()
    Notifications.scheduleNotificationAsync({
        content: {
          title: data.timeTitle
        },trigger: {
          seconds: data.seconds,repeats: false,},});

      console.log('Done')
    return BackgroundFetch.Result.NewData;
})


const HomeScreen = props => {


    console.log(data.nextSlot)
    async function registerBackgroundFetchAsync() {
        return BackgroundFetch.registerTaskAsync(ALARM_TASK_FETCH,{
          minimumInterval: 1,// 15 minutes
          stopOnTerminate: false,// android only,startOnBoot: true,// android only
        });
      }

    useEffect(() => {
       registerBackgroundFetchAsync()
    },[])

    const [isRegistered,setIsRegistered] = useState(false);
    const [status,setStatus] = useState(null);
  
    useEffect(() => {
      checkStatusAsync();
    },[]);
  
    const checkStatusAsync = async () => {
      const status = await BackgroundFetch.getStatusAsync();
      const isRegistered = await TaskManager.isTaskRegisteredAsync(ALARM_TASK_FETCH);
      setStatus(status);
      setIsRegistered(isRegistered);
      console.log(status,isRegistered)
    };

    return <View style = {styles.container}>
        <Text style = {styles.text}>
            Welcome to Home Screen
        </Text>
        <Text style = {styles.data}>
            Next alarm in <Text style = {{color : 'red',fontStyle : 'italic'}}>
            {data.nextSlot}
            </Text>
        </Text>
        <Text style = {styles.data}>
        with title of <Text style = {{color : 'red',fontStyle : 'italic'}}>
        {data.timeTitle}
            </Text> 
        </Text>
    </View>
}


const styles = StyleSheet.create({
    container : {
        flex : 1,backgroundColor : '#e8e8e8'
    },text : {
        textAlign : 'center',color : 'navy',fontSize : 22,fontStyle : 'italic'
    },data : {
        color : 'navy',textAlign : 'center',marginTop : 15
    }
});


export default HomeScreen;

这是我的 app.json 文件
