Let me start off by saying I'm brand new to Android programming. I'm using a Pragmatic's Hello Android book (3rd edition). I'm working on the popular sudoku game example, and after copying the code from the book that is to be placed in the main.xml file, I get the following errors:
error: Error: No resource found that matches the given name (at 'background' with value '@color/background')
.
error: Error: No resource found that matches the given name (at 'text' with value '@string/main_title').
error: Error: No resource found that matches the given name (at 'text' with value '@string/continue_label').
error: Error: No resource found that matches the given name (at 'text' with value '@string/new_game_label').
error: Error: No resource found that matches the given name (at 'text' with value '@string/about_label').
error: Error: No resource found that matches the given name (at 'text' with value '@string/exit_label').
They're probably all related, but after doing some searching, I don't know what the problem is. Any suggestions?
