我正在使用googlemaps v2，首先我收到错误“无法获取连接工厂客户端”Android MapActivity googlemaps : Couldn't get connection factory client。我尝试从一些教程中修复它，现在得到错误“FATAL EXCEPTION：main java.lang.NoClassDefFoundError”。

试试这个：
转到项目/属性/ Java构建路径/订单和导出 - 如果您使用它，请确保在Android Dependencies和支持库前面进行检查。标记所有复选框并单击“应用”并清除项目。
希望这有帮助。
答案 1 :(得分：0)
首先你应该安装Extras-＆gt; Android SDK管理器中的Google Play服务。然后，如果您使用的是Eclipse，请将库项目导入工作区。点击文件＆gt;导入，选择Android＆gt;将现有的Android代码导入Workspace，并浏览到库项目的副本以导入它。我可以解决这个问题。
