嘿，我正在尝试对Ionic应用程序进行远程调试，它最近正在运行，但是现在该设备在Chrome Remote设备上显示，但是当我单击该设备时，该应用程序进程将不会显示。它将显示其他移动chrome选项卡上的进程，而不显示Ionic应用程序。
有什么线索吗？
我需要使用离子框架（v4）从 android 应用程序打印 html 内容。我在官方文档中找到了cordova-plugin-printer，但我无法让它工作。根据docs，您只需稍后安装插件和包装器。
ionic cordova plugin add cordova-plugin-printer
npm install @ionic-native/printer
然后当注入打印机对象时，我收到 NullInjector 错误

我正在尝试将我的应用程序从 Cordova 迁移到 Capacitor，但我仍然需要使用诸如后台地理定位之类的功能。为此，我正在使用这个插件：https : //ionicframework.com/docs/native/background-geolocation
所以，为了测试这个，我创建了一个新的应用程序，添加了 Capacitor 并安装了这个插件。如此处所述（https://github.com/ionic-team/capacitor/issues/2529#issuecomment-603205348），我将此行添加到我的字符串文件中：
<string name="mauron85_bgloc_account_name">@string/app_name</string>
<string name="mauron85_bgloc_account_type">$PACKAGE_NAME.account</string>
<string name="mauron85_bgloc_content_authority">$PACKAGE_NAME</string>
在那之后，我跑了 npx cap sync
现在，每当我尝试构建应用程序时，都会收到以下错误：
Execution failed for task ':capacitor-cordova-android-plugins:compileDebugJavaWithJavac'.
在我的控制台中，上面有很多缺失的导入错误，如下所示：
C:\Users\zxy\Desktop\mobile_apps\testApp\android\capacitor-cordova-android-plugins\src\main\java\com\evgenii\jsevaluator\JsEvaluator.java:4: error: package android.support.annotation does not exist

知道如何让这个插件与 Capacitor 一起工作吗？

我正在尝试在 ionic 中构建构建时执行此操作，但该位置在 IOS 上并且不适用于 ionic 2 应用程序中的地理定位。
我已经安装了 ionic cordova plugin add cordova-plugin-geolocation 和
在 android 设备中，当位置服务打开时它正在工作。当定位服务关闭时，它不起作用。在 iOS 设备中，这两种情况都不起作用。需要一些帮助！！
import { Geolocation } from '@ionic-native/geolocation';
在提供者中，我提到了地理定位；在 home.ts 中，我导入了 Geolocation。
要获取当前位置，我编写了以下代码
getCurrentLocation(){
this.geolocation.getCurrentPosition().then((position) => {
let loc = {
placeId: null,
name:null,
lat:null,
long:null,
}
var lat = position.coords.latitude;
var lng = position.coords.longitude;
var latlng = new google.maps.LatLng(lat, lng);
var geocoder = geocoder = new google.maps.Geocoder();
}
我正在尝试在底部工作表中添加列表，但是 ionic 给了我们一个数组，因此我们可以在那里添加类并为其设置样式。我想问的是我们如何制作一个列表或完全我们自己的 html 代码并将其传递给将显示的底部工作表函数？
async presentActionSheet() {
const actionSheet = await this.actionSheetController.create({
header: 'Albums',

text: 'Delete',
