我的地图布局         

<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.SupportMapFragment"/>

我的地图java 

package com.example.tracker;
import com.google.android.gms.maps.*;
import com.google.android.gms.maps.model.*;
import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;

public class Tracking extends FragmentActivity  {

    private GoogleMap map;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_tracking);
 }
}

2 个答案:

答案 0 :(得分：0)

好像你没有正确添加google-play-service库。 您必须从sdk路径导入google-play-service库项目。 并在项目中使用此库。

有关分步指南，请参阅此帖Google Map v2

答案 1 :(得分：0)

您需要从Android SDK管理器下载Google Play服务，如果您使用的是eclipse，则需要导入项目并添加为项目的依赖项是[sdk_folder] / extras / google / google_play_services / libproject / google-play-services_lib，你就完成了。

这是官方文档 请访问：http://developer.android.com/google/play-services/setup.html
