c# - 找不到 Android 支持库和媒体路由器 .jar 文件

Question

我对 Xamarin 完全陌生。我想将 map 添加到 Xamarin.Android 中的默认 hello world。我已经按照指南一步步准备了我的 list 。还通过 sdk 管理器下载了支持库，但出现错误，要求我安装 SL 和 SL 媒体路由器。

这里是 list :

<?xml version="1.0" encoding="utf-8"?>

<!-- We need to be able to download map tiles and access Google Play Services-->
<uses-permission android:name="android.permission.INTERNET" />

<!-- Allow the application to access Google web-based services. -->
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />

<!-- Google Maps for Android v2 will cache map tiles on external storage -->
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<!-- Google Maps for Android v2 needs this permission so that it may check the connection state as it must download data -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

<!-- Permission to receive remote notifications from Google Play Services -->
<!-- Notice here that we have the package name of our application as a prefix on the permissions. -->
<uses-permission android:name="com.MyAppName.MyAppName.permission.MAPS_RECEIVE" />
<permission android:name="com.MyAppName.permission.MAPS_RECEIVE" android:protectionLevel="signature" />

<!-- These are optional, but recommended. They will allow Maps to use the My Location provider. -->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />


<application android:label="@string/app_name">

    <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyCV3Xs4ah1VkL8dI2JWmP2UiTlH4HZuQfQ" />
    <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" />
</application>

我得到的一些错误:

  /Users/apple/Projects/MyAppNameAndroid/MyAppNameAndroid: Error XA5207: Please install package: 'Android Support Library' available in SDK installer. Java library file /Users/apple/.local/share/Xamarin/Android.Support.v7.AppCompat/21.0.3/embedded/classes.jar doesn't exist. (XA5207) (MyAppNameAndroid)

(XA5209) (MyAppNameAndroid)

我还在 url 中下载了提到的 .zip 文件，但是没有像 /users/apple/.local 这样的文件夹……可以将其复制进去。

向应用程序添加 map 权限真的这么棘手还是我做错了什么？

我建议你阅读 this . Xamarin 提供了有关如何添加和设置 map fragment 的指南。

您还需要从 Xamarin 组件商店而不是 Android SDK 管理器安装 google play 服务组件。
