Question

我正在使用离子框架构建应用程序。该应用程序的主要功能是基于谷歌地图。我使用了this tutorial，它使用了java脚本google maps API。当我运行离子实验室或离子服务时，一切都很完美，但是当使用Android模拟器运行时：离线cordova运行android谷歌地图应该是完全空白的地方。我也没有收到任何错误消息。另外我使用的是cordova版本7.0.1和离子版本3.5.0。我已经尝试了this question中列出的两种解决方案，问题仍然存在。

以下是config.xml的希望相关部分，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:*" />
<allow-intent href="sms:*" />
<allow-intent href="mailto:*" />
<allow-intent href="geo:*" />
<access origin="*" />
<allow-navigation href="*" />
<allow-intent href="*" />
<allow-intent href="http://maps.google.com" />
<preference name="webviewbounce" value="false" />
<preference name="UIWebViewBounce" value="false" />
<preference name="DisallowOverscroll" value="true" />
<preference name="android-minSdkVersion" value="16" />
<preference name="BackupWebStorage" value="none" />
<preference name="SplashMaintainAspectRatio" value="true" />
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="SplashShowOnlyFirstTime" value="false" />
<preference name="SplashScreen" value="screen" />
<preference name="SplashScreenDelay" value="3000" />
<platform name="android">
    <allow-intent href="market:*" />

另外这里是index.html，我链接到api

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

这里要求的是使用谷歌地图的主页的ts html和css HTML

<ion-header>
<ion-navbar>
<ion-title>
  Smell Louisville
</ion-title>
</ion-navbar>
</ion-header>

<ion-content>

<ion-fab top right><button ion-fab round [color]="refr"id="Refr"     
(click)="refMap();setStuff();pickColor();getLatLng();markerOnLocal()"><ion-
icon name="refresh-circle"></ion-icon></button></ion-fab>

<div #map id="map"></div>
<div id="pad"></div>
<button (click)="openFormPage()" id="hundPer" ion-button outline     
[color]="button1"><div #LeavRev id="LeaVRev"><p id="CenterP">Report how your     
air smells</p></div></button>
<div id="pad"></div>
<button (click)="openPastPage();"id="hundPer" ion-button outline 
[color]="button2"> <div #Prev id="PreV"><p id="CenterP">View maps from 
previous days</p></div></button>
<div id="hundPer">
<button id="hundPer">
<button (click)="openSettingsPage()"><ion-icon id="right"name="settings">    
</ion-icon></button>
<button (click)="openAboutPage()"><ion-icon id="right"name="people"></ion-

<button (click)="openPMPage()" id="pad"><ion-icon id="right">PM2.5</ion-

</button>
<button (click)="openCitationPage()" id="pad"><ion-icon id="right" 
name="clipboard"></ion-icon></button>
<button (click)="openHelpPage()" id="pad"><ion-icon id="right" name="help">
</ion-icon></button>
<button (click)="openKeySendPage()" id="pad"><ion-icon id="right" 
name="key"></ion-icon></button>
</button>
</div>

CSS

page-home {
#map{height:75%}


#LeavRev{border:solid
;border-color: green}
#Prev{border:solid
;border-color: royalblue}
#pad{height:1%}
#padL{height:1%; width:10%; float:left}
#padR{height:1%; width:100%; float: right; background-color:#E5E5E5}
#refr{background-color: #6dc066;border:solid;align-content:right;border-                
color: green;color:whitesmoke}

#CenterP{text-align: center}
#hundPer{width:100%}

#right{float:right}
#left{float:left}

}

非常感谢任何帮助

Answer 1

事实证明我实际上解决了错误的问题。 api正在加载正常但是设备没有运行

中的任何代码

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

其中包含我生成地图的所有代码。为了解决这个问题，我在本节内部进行了一些与用户位置无关的问题，并将其放在initMap() this.geolocation.get...所在的方法中

谷歌地图不使用离子cordova运行android
