作为一个新手，我正在尝试开发一个基本的应用程序。总是，我导出它，并将其导入其他PC，我到处都会遇到错误。我和其他人一起尝试过，我遇到了同样的问题。 这个错误出现了：
"Description Resource Path Location Type
Archive for required library: 'C:/Documents and Settings/Administrador/workspace/Share it Fast/libs/android-support-v4.jar' in project 'Share it Fast' cannot be read or is not a valid ZIP file Share it Fast Build path Build Path Problem
The project cannot be built until build path errors are resolved Share it Fast Unknown Java Problem
Project has no target set. Edit the project properties to set one. Share it Fast Unknown Android Target Problem
Project has no target set. Edit the project properties to set one. Share it Fast Unknown Android Target Problem "
我认为它们是因为我没有放入库文件而生成的。但是，还有其他错误。 问题是：如何正确导入和导出？我不想得到更多错误或重新开始。 感谢。
