Android GooglePlayServicesUtil.isGooglePlayServicesAvailable（）崩溃

我在2.1版手机上运行它。当我调试它时，发现函数GooglePlayServicesUtil.isGooglePlayServicesAvailable（）崩溃

据说“找不到android.util.Base64.decode方法”。 版本2.1太低了？ 或者手机需要安装google play服务

代码如下：

int status=GooglePlayServicesUtil.isGooglePlayServicesAvailable(getBaseContext());
if (status!=ConnectionResult.SUCCESS)
{
   ...
}

以下是日志：
