Question

我的手机APP工作得很好。我有一台新计算机，已下载Eclipse + Android SDK，并收到以下错误消息：

[2013-12-11 13:31:45 - MyPulse] ERROR: Unable to open class file C:\Users\dridley\Dropbox\MyPulse\Martin Brown\ideaProjects\MyPulse\gen\com\palczewski\mypulse\Manifest.java: Permission denied

消息重复多次。

Answer 1

您的项目有多个org.json.simple.ItemList的jar。删除额外的罐子并重建。

此外，将工作区放在Dropbox文件夹中可能不是一个好主意。如果您需要备份或共享代码，请使用真实的版本控制系统。

移动APP停止工作
