Make sure you declared your activity com.example.gridviewexample.MainActivity in your AndroidManifest.xml.

Also, make sure that your MainActivity has the correct package name set in the top of the file (e.g package com.example.gridviewexample).

The system cannot find the MainActivity.class in your com.example.gridviewexample package.

Take a look to see if you have such a class in there.

A Project -> Clean could also help(provided you're using Eclipse).
