标签： android google-maps google-maps-api-2

我想使用Google Map v2在地图中显示当前位置。我创建sha密钥并生成API密钥，并与androidmanifest.xml集成。我下载以下链接的示例：

我也提供互联网权限，但在我的log-cat中显示以下错误。

地图活动 

public class MainActivity extends FragmentActivity {


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



}

<强> activity_main 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <fragment xmlns:android="http://schemas.android.com/apk/res/android"
          android:id="@+id/map"
          android:layout_width="match_parent"

</manifest>

打开sdk管理器并在额外内容下载google play服务，您将获得两个库google-play-services_lib.jar和google-play-services.jar。您可以在Google Play服务中找到这些库。您必须复制这两个库并粘贴到应用程序中的 lib 文件夹下，并在java Build path下添加这些库。

请确保通过google api console转到服务下去，你会发现google map v2 eanble it ... enter image description here 要添加对库项目的引用，请按照下列步骤操作：

    1. Make sure that both the project library and the application project that depends on it are in your workspace. If one of the projects is missing, import it into your workspace.
    2. In the Package Explorer, right-click the dependent project and select Properties.
    3.In the Properties window, select the "Android" properties group at left and locate the Library properties at right.
    4.Click Add to open the Project Selection dialog.
    5.From the list of available library projects, select a project and click OK.
    6.When the dialog closes, click Apply in the Properties window.
    7.Click OK to close the Properties window.
