@Jerrod1225: Most of the errors people are having with this app have to do with Key Listeners that are introduced in a later chapter. Page 38 explains why.
If you are having issues with this line
Code:
myEditText.setOnKeyListener(new OnKeyListener()
and you are using eclipse, put your mouse pointer over the term OnKeyListener.
When the tooltip pops up choose the "import onKeyListener (android.view.View)" class.
