android - 如何实现谷歌地图新版API v2

Question

大家好，我了解到谷歌地图已弃用其先前版本的 API v1，并引入了新版本的谷歌地图 API v2。我通过跟踪 google 中的一些链接尝试了一个示例，我非常确定我通过提供准确的散列 key 代码并设法获得正确的 api key 而正确地获得了 api key 。现在我也设法编写了一些代码，但是当我尝试执行代码时出现错误，请帮助我解决这个问题这是我的代码

我什至尝试了 google play 服务提供的示例代码，但我遇到了同样的问题

这是我通过引用google中的一些链接完成的示例

主要 Activity 类

package com.example.apv;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;
import android.os.Bundle;
import android.app.Activity;
import android.app.FragmentManager;

public class MainActivity extends Activity 
{
     @Override  
     protected void onCreate(Bundle savedInstanceState) {  
         super.onCreate(savedInstanceState);  
         setContentView(R.layout.main);  

     FragmentManager fragmentManager = getFragmentManager();  
     MapFragment mapFragment = (MapFragment)fragmentManager.findFragmentById(R.id.map);  
     GoogleMap googleMap = mapFragment.getMap();  
     LatLng sfLatLng = new LatLng(37.7750, -122.4183);  
     googleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);  
     googleMap.addMarker(new MarkerOptions().position(sfLatLng).title("San Francisco")
                .snippet("Population: 776733")
            .icon(BitmapDescriptorFactory.defaultMarker(
     BitmapDescriptorFactory.HUE_AZURE)));
     googleMap.getUiSettings().setCompassEnabled(true);  
     googleMap.getUiSettings().setZoomControlsEnabled(true);  
     googleMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sfLatLng, 10))

        }  
}  

主.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"  
                               class="com.google.android.gms.maps.MapFragment"/>  

最后是我的 list 文件

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

     application android:label="@string/app_name" android:icon="@drawable/ic_launcher">

                 <activity android:name=".MyMapActivity"  
                         android:label="@string/app_name"   
                             >   
                          <intent-filter>

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

                           <meta-data  
                             android:name="com.google.android.maps.v2.API_KEY"

                            </application>  


                          </manifest>  

我在版本 4.2 和 api 级别 17 的模拟器中运行我的应用程序我得到以下错误

12-17 10:06:52.590: E/Trace(826): error opening trace file: No such file or directory (2)

后来我知道这些版本不能在模拟器中执行，所以我尝试用两个设备执行它，一个是 android 版本 2.3.7 的 Sony xperia u 和 android 版本 4.1.1 的 Samsung galaxy tab，这些是我的输出

任何人都可以建议我如何完成这项工作并给我一些谷歌地图新版本 API v2 教程的链接和一些示例链接请帮助我

按照在类似帖子中找到的指南进行操作可能会有所帮助，您需要安装 2 个 .apk 文件。来源:http://nemanjakovacevic.net/blog/2012/12/how-to-make-android-google-maps-v2-work-in-android-emulator/
