但是应用程序没有崩溃，一切都运转良好。我的LogCat向我投掷的东西是什么意思？

1 个答案:

答案 0 :(得分：3)

查看ICS源代码 - 似乎无论出于何种原因，程序包管理器无法获取您的程序包信息 - 它可能只是一个eclipse / ADT错误，其中eclipse对文件持有某种锁定，但无论如何是的，它似乎不是你的代码可能导致的东西。我建议运行一个干净的，从模拟器/设备卸载应用程序，或者如果这些不起作用，你可以尝试一个新的eclipse工作区。

另一个可能是问题的问题是，如果你正在使用一个图书馆项目 - 尝试取消链接这两个项目，清理，然后再将它们重新连接起来 - 但这就是我的行李诀窍：）
