If you are new to Java programming, I recommend watching those videos first. Android programming requires that you have a solid Java background.

Random randomGenerator;
Random randomGenerator = new Random();
// The problem with these two line of code is that you declared the exact 
// same variable name (randomGenerator) twice.
