Java Android地图：无法加载地图。无法联系谷歌服务器

这个错误一直存在。（我确保“谷歌地图Android API v2”是打开的。）

请帮忙！我不确定出了什么问题……尽管我最终还是遵循了/合并了各种教程，因为它们都不是独立工作的。

1。我看到的第一个问题是：

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="17" />

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


    <uses-permission android:name="com.example.maptest.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <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-feature
        android:name="android.hardware.location"
        android:required="true" />
    <uses-feature
        android:name="android.hardware.location.network"
        android:required="true" />
    <uses-feature android:name="android.hardware.location.gps" />
    <uses-feature
        android:name="android.hardware.wifi"
        android:required="true" />

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <uses-library android:name="com.google.android.maps" />

        <activity
            android:name="com.example.maptest.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyAoDwhSzOopQ3g8NBe7d0WblR72TkmnVPU" />


    </application>

</manifest>

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

2.从清单文件中删除此行：

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="17" />

     <permission

    <uses-permission android:name="com.example.maptest.permission.MAPS_RECEIVE" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
    <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-feature
        android:name="android.hardware.location"

        android:required="true" />
    <uses-feature android:name="android.hardware.location.gps" />
    <uses-feature
        android:name="android.hardware.wifi"
        android:required="true" />

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

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >

        <uses-library android:name="com.google.android.maps" />

        <activity
            android:name="com.example.maptest.MainActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <meta-data

    </application>

</manifest>

<uses-library android:name="com.google.android.maps" />

这是Google Maps

API V1

权限，不应在

API V2

中使用

3.您描述的问题通常源于使用API控制台生成或注册API密钥时出现的问题，如果您确信所有步骤都正确，那么我建议您删除debug.keystore文件夹，在Eclipse中编译某个项目（这将产生一个新的SHA1密钥）并使用控制台再次注册密钥。看看我写的这篇博文，确保我做的所有步骤都是正确的：

    <uses-sdk
        android:minSdkVersion="17"
        android:targetSdkVersion="17" />

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


    <uses-permission android:name="com.example.maptest.permission.MAPS_RECEIVE" />

1。您的签名密钥和包名是否为该API密钥正确注册？2.你花了多长时间？API密钥并不总是立即生效。嗨，Emil Adz，我已经按照这些步骤成功创建了一个地图示例应用程序。它在大多数设备上都能工作（我在Galaxy Ace plus、Galaxy 7英寸标签和sony xperia Z上进行了测试）。但当我尝试在HTC Desire上测试时，它会显示错误，如“找不到从方法maps.z.ag.a引用的类‘maps.i.k’。加载map失败。无法联系Google服务器”。我已经在设备中交叉验证是否安装了Google play服务。所以你能帮我解决这个问题吗？@Raj，请提出一个新问题，我会尽力帮助你。永远不要对你的问题发表评论。谢谢Emil Adz，在设备中更新地图应用程序后，它现在对我有效。不管怎样，谢谢你的支持。我很高兴你能解决这个问题。考虑到您的应用程序在除此设备之外的所有设备上都工作，实际上会显示一个标志，表明设备配置中存在某些内容，而不是您的应用程序。如果有人仍在寻找答案，请检查此处-相同的问题：
