Error parsing XML - not well formed (invalid token)

Question

I have already checked the other XML files for errors, however this is the file that the error message is saying the error is in. There is also a message that pops up whenever I try to run the app that says, "Files under the build folder are generated and should not be edited".

There is also a message that pops up whenever I try to run the app that says, "Files under the build folder are generated and should not be edited".

I think you are changing the .class file in debug/DDMS mode or something like that. Please check and make sure to edit your .java file instead.

Posting your relevant logcat messages and also the XML file in question might help understand the problem.
