To fix this problem, simply delete the `debug.keystore file.`

The default storage location for AVDs is

• In `~/.android/` on OS X and Linux.
• In `C:\Documents and Settings\<user>\.android\` on Windows XP
• In `C:\Users\<user>\.android\` on Windows Vista and Windows 7.

For Windows XP go to `C:\Documents and Settings\%userprofile%\.android` and delete `debug.keystore`, restart Eclipse and now your project will build without the error.

Example path: `C:\Documents and Settings\raja.ap\.android\` For other Windows versions, find your user folder and then delete the file.

Use the keytool utility to create a new debug keystore. The keystore that you are using has expired and that is the reason why you see the project shows up in eclipse with errors.

check this out http://www.androiddevelopment.org/tag/keytool/

Also before doing that delete the existing debug keystore from the location in Windows or Linux based on the OS you are using.
