無法加載地圖使用谷歌地圖的Android API V2

Question

加載谷歌地圖的Android API V2，當我得到這個下面的錯誤

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 

這裏是我的源代碼：

我AndroidManifest源代碼

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"> 
    <uses-sdk android:minSdkVersion="14" android:targetSdkVersion="14" /> 

    <application android:label="map" android:icon="@drawable/Icon"> 
     <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version" /> 
     <meta-data android:name="com.google.android.maps.v2.API_KEY" android:value="AIzaSyDjm0K-ucpO5mDCPPnQ4CzVpdguqM714uo" /> 
    </application> 

    <permission android:name="com.example.permission.MAPS_RECEIVE" android:protectionLevel="signature" /> 

    <uses-permission android:name="com.example.permission.MAPS_RECEIVE" /> 
    <uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /> 

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

    <uses-permission android:name="android.permission.INTERNET" /> 
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /> 
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /> 
    <uses-permission android:name="android.permission.READ_GSERVICES" /> 
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
</manifest> 

我Main.axml源代碼

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源代碼

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); 
     } 
    } 
} 

順便說一句，我使用API​​ Level 15模擬器。

這是我的API密鑰

Answer 1

我找到了答案，我的問題。我的SHA1指紋不符合我使用的證書指紋（在我的錯誤消息中）。現在我的應用程序正確加載Android谷歌地圖。

Answer 2

編寫以下功能將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

雖然不推薦，它是p可以設置模擬器來支持Android Maps API v2。仿真器必須配置爲定位Google API API 17（Android 4.2.2）或更高版本的。
你的是設置爲API等級15 ...

另外你需要將項目的目標API和API最小級別設置爲17（目前14）如果你想加載模擬器谷歌地圖。
