将Android应用程序项目从Windows导入Mac / Eclipse

标签： android eclipse macos

我在Windows上开发了一个Android应用程序，它工作得很好！也在我的设备（三星年轻）上工作，但当我将它导入Mac时，我遇到了在Galaxy S3上启动它的问题。我可以提到代码是正确的，并且在设备中安装它时没有错误，问题是当它在设备上运行时它会突然停止并显示一条消息“不幸的是MySupermarket已经停止了”。

我需要你的帮助，因为我不是高级开发人员。

这是LogCat：

执行以下步骤后问题仍然存在，这是以下步骤后的LogCat：

要修复此异常，请转到Eclipse，右键单击Project properties。您将从左侧菜单中单击Java Build Path并在右侧单击Order and Export选项卡中弹出属性。在该选项卡内取消选中Android Dependencies，之后只需清理您的构建并再次运行。
