I just added Google Play Service Library to my project and when I am making a modification in one of my project files I am keep getting an error dialog from eclipse:
This is a workaround (not exactly the solution). In Window > Preferences > Android > Lint Error Checking, uncheck "When saving files check for errors".
EDIT:
Please use the above steps only if you don't care about linting your code. These steps are for turning off Lint checking, not correcting the reported lint errors.
I would suggest for you to check on the warnings on your project. Resolving them one by one may get rid of the startup error.
