Errors in Eclipse for no reason

I'm building an Android app.

I worked today on my app, and suddenly I saw that all the projects in the workspace are marked with an error. I don't know what caused it, and I can't find explanation of the error anywhere.

I'm using Helios with Windows 7. I even tried downloading Eclipse again but it didn't help.

Today I tried to integrate Facebook with my app. Their tutorial required me to try to get a hesh key from a keystore. In the process I added an Environment Variable named JAVA_HOME, and pointed it to the JDK.

I don't know if it's the cause of my problem, but I think it might be related.

I really don't know what to do.

Thanks!

Typically, the problem is with a resource you've recently added to your project (drawable, assets, raw, etc.)

Some things to check are:

Invalid XML files
Invalid 9-patch images (outer 1-pixel border must be full black or transparent)

Typically, just start by removing a resource, then cleaning your project (Project > Clean). If the errors go away, that resource is your problem. If not, continue this process until the error DOES go away. Start with the most recent resources you've added, naturally.
