if you are trying to build on emulator than.. point 3 in above link might be usefull to you 如果您要在仿真器上构建比..以上链接中的第3点可能对您有用

3.Install a compatible version of the Google APIs platform.If you want to test your app on the emulator, expand the directory for Android 4.2.2 (API 17) or a higher version, select Google APIs, and install it. 3.安装兼容版本的Google API。如果要在模拟器上测试应用，请展开适用于Android 4.2.2（API 17）或更高版本的目录，然后选择Google API并进行安装。 Then create a new AVD with Google APIs as the platform target.Note: Only Android 4.2.2 and higher versions of the Google APIs platform include Google Play services. 然后，以Google API为平台目标创建新的AVD。注意：只有Android 4.2.2和更高版本的Google API平台才包含Google Play服务。

Its better to look all the points and setup a working new project. 最好查看所有要点并设置一个可以正常工作的新项目。

You obviously don't have the fragment support library in you compile path. 显然，您的编译路径中没有片段支持库。 The map fragments needs the v4 compatibility library in the compile path. 映射片段在编译路径中需要v4兼容性库。 The map samples are a bear to get straight I followed these directions. 地图样本是我按照这些指示直行的熊。 http://developer.android.com/tools/support-library/setup.html http://developer.android.com/tools/support-library/setup.html
