在android中映射活动

Question

我已经创建了地图actvity.But它没有在mapview.just上显示地图显示空白块.有什么办法吗？

activity_main.xml-

 <?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"/>

活动代码 -

package com.example.googlemap;


import android.app.Activity;
import android.os.Bundle;
public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}
}

清单文件 -

  <uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="16" />

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

<meta-data
    android:name="com.google.android.maps.v2.AIzaSyDRv4Ul_9iPW-roHIsc8EuxKwkRN8jWivs"
    android:value="AIzaSyDRv4Ul_9iPW-roHIsc8EuxKwkRN8jWivs" />

<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" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="com.example.googlemap.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>

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

使用这个之后 我得到以下例外 -

  08-22 23:19:52.204: E/AndroidRuntime(584): FATAL EXCEPTION: main
  08-22 23:19:52.204: E/AndroidRuntime(584): java.lang.RuntimeException: Unable to       start activity ComponentInfo{com.example.googlemap/com.example.googlemap.MainActivity}: android.view.InflateException: Binary XML file line #7: Error inflating class fragment

旧的MapView已被折旧.您无法为发布应用创建新的地图密钥.您必须使用新的Google Maps for Android v2 API.这是文档和示例的链接. https://developers.google.com/maps/documentation/android/start
