我遇到了一个问题，它真的很烦人。几天前，我也遇到了这个问题，当时只是将"最低"one_answers"目标"android版本更改为"21"，就解决了这个问题。然而，这一次不起作用。
错误：

同时附加生成输出文件。
请尽快通知。另外，请注意，这个错误是在我添加了一个xml文件（Menu.xml）后开始发生的。我现在已经删除了该文件，但错误仍然存在。
这些文件中存在非标准信息。这只是一个警告，不应该影响应用程序。如果你和我一样，想摆脱所有警告，有一种方法可以绕过它。
看看这个堆栈溢出的答案。
对我来说，这是由资产Resource名称上的"-"引起的。
代替account-icon.png，我将其更改为account_icon.png
希望这能有所帮助。
