title: Google app engine endpoints for android suddenly not working when trying to launch in eclipse
body: <p>I have an android project where I am using the generated client libraries for google app engine.  IT was working great until suddenly I am getting an error marker on the endpoint-libs folder.  inside the folder there is no specific file with an error market on it, but It wont let me launch the application.  I get no error in the console, and I did absolutely nothing to the code.  It simply just stopped working.  Does anyone know what might have caused this?  I appreciate any responses because i'm clueless.  </p>
