Question

我在使用与其他应用程序中使用的代码相同的代码尝试使用GoogleMapApi V2时遇到了问题。 我想要的只是做StartActivity（MapActivityFragment）;没有错误

我有这些权限

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

<permission
    android:name="com.egdigital.appetablissement.permission.MAPS_RECEIVE"
    android:protectionLevel="signature" />
<uses-permission android:name="com.egdigital.appetablissemen" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.VIBRATE" />
<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" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

<application
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="theApiKey" />

<activity
    android:name="com.egdigital.appetablissement.ActivityGoogleMap"
    android:configChanges="orientation"
    android:label="@string/app_name" >
</activity>

包含地图支持片段的XML：activity_maps

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

此类用于管理地图

public class ActivityGoogleMap extends SherlockFragmentActivity {
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_maps);
    }
}

我已将ActionBarSherlock和googlePlayServices-lib 列为库

还包括android-support-v4.jar 作为外部jar并将其添加到依赖项中

当我执行StartActivity（MapActivityFragment）时，我遇到了一个很大的错误：

FATAL EXCEPTION: main
java.lang.RuntimeException: Unable to start activity     ComponentInfo{com.egdigital.appetablissement/com.egdigital.appetablissement.ActivityGoogleMap}: android.view.InflateException: Binary XML file line #2: Error inflating class fragment

看起来<application>中的<meta-data>和AndroidManifest.xml元素存在一些错误的格式。

所以，以下内容：

<application
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="theApiKey" />

<activity
    android:name="com.egdigital.appetablissement.ActivityGoogleMap"
    android:configChanges="orientation"
    android:label="@string/app_name" >
</activity>

......应改为：

<application>        
    <activity
        android:name="com.egdigital.appetablissement.ActivityGoogleMap"
        android:configChanges="orientation"
        android:label="@string/app_name" >
    </activity>
    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="theApiKey">
</application>

Android Maps API v2文档： https://developers.google.com/maps/documentation/android/start#adding_the_api_key_to_your_application

...说：

在AndroidManifest.xml中，将[meta-data]元素添加为元素的子元素，方法是在结束标记</application>之前插入。
