Android模拟器运用KSOAP2调用WebService

Android模拟器使用KSOAP2调用WebService

?

??? 项目需要Android去访问webservice，网上找了很多例子、中英文网站，每次运行都是出现错误“The application ***(process? 包名) has stopped unexpectedly.Please try again “ ，困扰了好几天，是因为Eclipse导入ksoap2-android-assembly-2.4-jar-with-dependencies.jar包的时候的方式的问题。

???? 之前导入jar包的时候，右键工程 Build path, java build path,选择libraries，在右边的按钮中点击“Add Library”，选择“User library”,点击“下一步”，点击“User librarys”按钮， 在出现的界面中点击“New..”按钮，在弹出的界面中随便起一个名字，点击“确定”， 点击“Add jars”按钮选择第三方jar包，点击“确定”完成操作。

??? 后来右键工程，Build path,java build path,选择libraries,在右边的按钮中点击“Add External JARs”,然后选择合适的jar包。

??? 还有一个问题就是Android模拟器访问Tomcat上部署的webservice程序时，不能用localhost 或者本级IP，Android默认访问本机地址为10.0.2.2。
