Remove unwanted resources under Android with one click

The project needs to change again, the UI a tune again, the result is a bunch of items in the project has not been used but not clean up the garbage resources, not to mention the project size problem, for the new entry of the person or look at the code of other modules, these clean resources may also be troubled, so it is best to clean up the rubbish, For a slightly larger project, manual cleanup is obviously unrealistic, which requires a way to do these things.

I fear the code word, the above content introduced http://www.cnblogs.com/angeldevil/p/3725358.html

About the use of Android lint, if you do not know, please go to understand.

Here is my clear code, mainly using DOM node parsing to remove useless resources, need to introduce Dom.jar, recommend to this warehouse to download http://search.maven.org/, speed can also. The code is not optimized for temporary writing.
