我试图在android studio中构建我的ionic应用程序，但收到了此错误

似乎前台服务出了问题，我该如何解决
这是我在应用程序中使用前台服务的方式

import { ForegroundService } from '@ionic-native/foreground-service';
ForegroundService.start('GPS Running', 'Background Service', 'drawable/fsicon');

androidmanifest.xml

<application  >
<service android:name="de.appplant.cordova.plugin.background.ForegroundService"/>
<service android:name="com.davidbriglio.foreground.ForegroundService" android:stopWithTask="true"/>
</application>

下面是我使用foregroundservices的main.js文件 main.js ```
import { BackgroundMode } from '@ionic-native/background-mode';
import { ForegroundService } from '@ionic-native/foreground-service';
import { defineCustomElements } from '@ionic/pwa-elements/loader';

import { Plugins } from '@capacitor/core';
import Pusher from "pusher-js";
import StoragePlugin from 'vue-web-storage';

const { App, PushNotifications } = Plugins;

const routerEl = document.querySelector('ion-router');
console.log('Ro', routerEl)
document.addEventListener('ionBackButton', (ev) => {
ev.detail.register(-1, () => {
const path = window.location.pathname;
if (path === routerEl.root) {
App.exitApp();
}
});
});
BackgroundMode.enable();
BackgroundMode.on('activate', () => {
BackgroundMode.disableBatteryOptimizations();
BackgroundMode.disableWebViewOptimizations();

})

ForegroundService.start('GPS Running', 'Background Service', 'drawable/fsicon');

const app = createApp(AppMain)
.use(IonicVue)
.use(router)
.use(RouterPrefetch)
.use(StoragePlugin)

.use(store);
defineCustomElements(window);
router.isReady().then(() => {
app.mount('#app');
});

下面是我使用foregroundservices的main.js文件
