无法加载地图使用谷歌地图的Android API V2

Question

加载谷歌地图的Android API V2，当我得到这个下面的错误

1. Authorization failure. 
2. Ensure that the following correspond to what is in the API Console: Package Name: com.example, API Key: AIzaSyDjm0K-ucpO5mDCPPnQ4CzVpdguqM714uo, Certificate Fingerprint: D9595FF0F329A6BBAC466C63284F83D17859894B 
3. Failed to contact Google servers. Another attempt will be made when connectivity is established. 
4. Failed to load map. Error contacting Google servers. This is probably an authentication issue (but could be due to network errors). 
5. Failed to find provider info for com.google.android.gsf.gservices 

这里是我的源代码：

我AndroidManifest源代码

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?> 
<manifest xmlns:android="http://schemas.android.com/apk/res/android" android:installLocation="auto" package="com.example">

我Main.axml源代码

Main.axml

<?xml version="1.0" encoding="utf-8"?> 
    <fragment xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/map" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    class="com.google.android.gms.maps.MapFragment" /> 

我的活性1源代码

Activity1.cs

using System; 

using Android.App; 
using Android.Content; 
using Android.Runtime; 
using Android.Views; 
using Android.Widget; 
using Android.OS; 

namespace map 
{ 
    [Activity(Label = "map", MainLauncher = true, Icon = "@drawable/icon")] 
    public class Activity1 : Activity 
    { 
     protected override void OnCreate(Bundle bundle) 
     { 
      base.OnCreate(bundle); 

      SetContentView(Resource.Layout.Main); 
     } 
    } 
} 

顺便说一句，我使用API​​ Level 15模拟器。

这是我的API密钥

Answer 1

我找到了答案，我的问题。我的SHA1指纹不符合我使用的证书指纹（在我的错误消息中）。现在我的应用程序正确加载Android谷歌地图。

Answer 2

编写以下功能将menifest

<uses-feature 
     android:glEsVersion="0x00020000" 
     android:required="true" /> 

Answer 3

提高XML

<fragment 
      android:id="@+id/map" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      class="com.google.android.gms.maps.**SupportMapFragment**" /> 

Answer 4

虽然不推荐，它是p可以设置模拟器来支持Android Maps API v2。仿真器必须配置为定位Google API API 17（Android 4.2.2）或更高版本的。
你的是设置为API等级15 ...

另外你需要将项目的目标API和API最小级别设置为17（目前14）如果你想加载模拟器谷歌地图。
