膨胀类片段谷歌 API 时出错

Question

我在网上搜索了很多，但我不知道我的错误在哪里。我第一次尝试使用 Android APIs for Maps。 这是我的代码：

public class MapClass extends FragmentActivity
{

    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.info_restaurant_layout);
    }
}

这是我的清单：

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="it.android.test"
android:versionCode="1"
android:versionName="1.0" >

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

<uses-sdk
    android:minSdkVersion="14"
    android:targetSdkVersion="19" />

<uses-permission android:name="it.android.pizzapp.ui.activity.permission.MAP_RECEIVE" />
<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" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

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

    <meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="AIzaSyAXB5clxSzUdT8..." />

    <activity
        android:name="it.android.test.activity.MainActivity"
        android:label="@string/app_name" >
        android:theme="@style/CustomActivityTheme"
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="it.android.test.activity.MapClass"
        android:label="@string/app_name" >
        android:theme="@style/CustomActivityTheme"
    </activity>
</application>

这是我的 MapClass 的 XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

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

</LinearLayout>

这是我的堆栈跟踪：

AndroidManifest.xml does not have the right value.  Expected 4242000 but found 0.
You must have the following declaration within the <application> element:
<meta-data android:name="com.google.android.gms.version"android:value="@integer/google_play_services_version" />

我尝试按照日志猫所说的那样更改元数据，但错误并没有消失。 有人可以帮我吗？

Answer 1

改变这个

public class MapClass extends FragmentActivity

到

public class MapClass extends Activity

还有这个

android:name="com.google.android.gms.maps.SupportMapFragment"

到

android:name="com.google.android.gms.maps.MapFragment"

删除

class="com.google.android.gms.maps.SupportMapFragment" 

添加这个

<meta-data 
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
