96 errors when compiling app

Hi I saw some source code on this website "java2s.com/Code/Android/Database/SearchableDictionary.htm", all the code is displayed in one block so I copy pasted into separate files using the file names in the comments and then put them in a new project. After opening the ide there was 96 errors most of them say unknown entity and I am unsure whats wrong

I have managed to get it to 0 errors but the app crashes on start up, here is the code drive.google.com/folderview?id=0B0wvwIy3_WGhdl9ZbkF2dE1WeWs&usp=sharing
