问题
I configured the AndEngine example on my eclipse a day ago by following a video tutorial. It was running fine. But the very next day, when I tried to run the example, it says your project contains errors. I check the properties of project and other things but found nothing like error. I am unable to figure out what is causing the project to build. Can anyone help me in this regard?
I can't see any error. I just show a cross on Examples project. I deleted all the extensions and examples and redownloaded but error stayed there. Here is the screenshot of eclipse.
Sometimes, when I delete some other project, it gives the following error message:
An internal error occurred during Re-indexing repository AndEngine Empty path not permitted.

Ah, I got rid of problem. Actually my debug certificate was expired. That's why it was not building the project. I deleted the Debug.keystore file from .android folder to regenerate the keystore.
