谷歌地图不适用于离子科尔多瓦运行安卓

Question

我正在使用离子框架构建一个应用程序。该应用程序的主要功能基于谷歌地图。我使用了本教程，它使用java脚本谷歌地图API。当我运行离子实验室或离子服务时，一切都很完美，但是当通过运行使用安卓模拟器时：离子科尔多瓦运行安卓谷歌地图应该在的地方是完全空白的。我也没有收到任何错误消息。此外，我正在使用科尔多瓦版本7.0.1和离子版本3.5.0。我已经尝试了此问题中列出的两种解决方案，但问题仍然存在。

这是配置的希望相关部分.xml正如另一篇文章所建议的那样

<content src="index.html" />
<access origin="*" />
<access origin="http://maps.google.com" />
<access launch-external="yes" origin="geo:*" />
<allow-navigation href="http://ionic.local/*" />
<allow-intent href="http://*/*" />
<allow-intent href="https://*/*" />
<allow-intent href="tel:*" />

<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="3000" />
<platform name="android">
<allow-intent href="market:*" />

此外，这里是索引.html我链接到 api 的地方

<script src="https://maps.google.com/maps/api/js?key=
MY_ACTUAL_API_KEY" type="text/javascript"></script>
<script src="cordova.js"></script>

根据此处的要求，是使用谷歌地图的主页的ts html和css .html

<ion-header>
<ion-navbar>
<ion-title>

</ion-title>
</ion-navbar>
</ion-header>
<ion-content>

<div #map id="map"></div>

任何帮助将不胜感激

Answer 1

事实证明，我实际上是在解决错误的问题。api加载正常，但是设备没有运行内部的任何代码

this.geolocation.getCurrentPosition().then((position) => {
...
});

其中包含我用于生成地图的所有代码。为了解决这个问题，我将本节中与用户位置无关的所有内容都放在initMap()，这是this.geolocation.get...所在的方法
