1、An exception occurred: org.ksoap2.SoapFault
SoapFault - faultcode: ‘soap:Server‘ faultstring: ‘服务器无法处理请求。 ---> 未能加载文件或程序集“MySql.Data, Version=6.3.9.0, Culture=neutral, PublicKeyToken=c5687fc88969c44d”或它的某一个依赖项。系统找不到指定的文件。‘ faultactor: ‘null‘ detail: [email protected]
原因：webservice 中采用了强类型数据集（DataSet）连接MySql数据库,简化数据库底层开发
解决：装一下mysql-connector-net-6.3.9.msi就可以了，文章下面有地址
2、Android访问webservice 帮助类，源码如下：

3、invalid project description
a、此错误简单翻译为：无效的项目描述。点击错误对话框中的detail按钮，提示为：overlaps the location of another project的描述，翻译成中文也就是说导入的项目位置与另外一个项目重叠。
b、导致此错误的很有可能的原因之一为：此项目在eclipse的工作目录之下。所以，将项目拷贝到另一个目录下，然后再尝试导入，大部分情况下是可以解决此问题的。
