In any activity of my project, if i do some changes and then save that activity i got the message “Running android lint has encountered a problem.”
This is the my error log :
java.lang.NullPointerException

I don’t to know how to solve this.
However, the root cause here is some sort of invalid project definition — one or more of the class path entries are pointing to a resource which can’t be opened; for example, you might have a classpath reference which is relative to a class path variable, and the class path variable is no longer pointing to an absolute location.
The above CL will simply make sure that lint doesn’t throw an exception in this scenario, but it won’t be able to do actually include the given reference.
You’ll want to look at the project properties dialog and make sure all the build paths and resources are correct — and that’s the workaround until this issue is integrated
