Android Studio集成了Google Maps API v2

Question

我正在尝试使用Android Studio在Android应用上创建一个显示Google地图的示例。我的目的是支持API级别14及以上。当我使用Google Map Activity创建一个新项目时，它可以正常工作，但使用 SupportMapFragment 而不是 MapFragment ，建议使用API​​级别12及更高版本。
我已经关注了Google开发者的Getting Started指南。

我无法看到地图。当我想要显示包含地图的活动时，应用程序会关闭。错误在设置内容视图的行上。

setContentView(R.layout.activity_map);

我的activity_map.xml是：

<?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"
      android:name="com.google.android.gms.maps.MapFragment"/>

在buld.gradle（Module：app）中，我在依赖项中有以下行

compile 'com.google.android.gms:play-services:6.5.87'

在AndroidManifest.xml中

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.albanianwonders.googlemapapiv2" >


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

    <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="com.google.android.providers.gsf.permission.READ_GSERVICES" />
    <!--
         The following two permissions are not required to use
         Google Maps Android API v2, but are recommended.
    -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />


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

    <activity android:name=".MapActivity"
        android:label="@string/title_activity_map">
        <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.geo.API_KEY"
        android:value="MY_API_KEY_IS_HERE" />
    <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

</application>

我得到的错误是

我在配置中遗漏了什么？
如何验证我是否已在Android Studio中正确导入Google Play服务？

Answer 1

我已阅读您的代码，代码正确。您使用此库

  

编译'com.google.android.gms：play-services：4.2 +'

Answer 2

谢谢大家花时间帮助我 我自己找到了答案。我的错误是我已将uses-permission和uses-features放在<application> ... </application>标记内。

必须放在<manifest> ... </manifest>标记内。

正确的AndroidManifest.xml是：

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

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

<!--

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
