在Android Studio Emulator上运行Google地图活动时出错

更新2:

我将build.gradle（模块：app）的行从

编译'com.google.android.gms:play services:8.1.0'

致：

编译'com.google.android.gms:play services地图：8.3.0'

现在我得到一个错误：

'W/GooglePlayServicesUtil: Google Play services out of date.  Requires 8298000 but found 8185470'

模拟器还有一个按钮，屏幕上现在显示“更新”，并显示“除非您更新Google Play服务，否则XXX不会运行。”

更新：

我在错误行中注意到：

Android Application (<cert_fingerprint>;<package_name>): 63:99:6C:AC:5A:45:3C:8B:26:D1:7F:45:52:E5:FB:01:A3:00:8E:E2;com.lightningboltstudios.audubontrailmap

致：

然后我开始出现这个新错误：

E/b: Authentication failed on the server.
E/Google Maps Android API: Authorization failure.  Please see https://developers.google.com/maps/documentation/android/start for how to correctly set up the map.
E/Google Maps Android API: In the Google Developer Console (https://console.developers.google.com)
Ensure that the "Google Maps Android API v2" is enabled.
Ensure that the following Android Key exists:
API Key: (redacted)
Android Application (<cert_fingerprint>;<package_name>): 63:99:6C:AC:5A:45:3C:8B:26:D1:7F:45:52:E5:FB:01:A3:00:8E:E2;com.lightningboltstudios.audubontrailmap

我的google_maps_api.xml值文件是：

<resources>
<string name="google_maps_key" templateMergeStrategy="preserve" translatable="false">(redacted)</string>

（修订）

这是目前Android Studio模拟器和Genymotion作为插件的限制。您只需使用一台实际的设备，即可在此时（2015年12月14日）处理任何使用google play服务的设备。

模拟器没有提供play服务，因此您需要以某种方式安装它。我从来没有让它工作过。当我一周前第一次去他们的网站试用时，它工作得很好。他们有一个循序渐进的过程。但这次它不起作用了。
