Java – no resource matching the given name can be found (in ‘text’, the value is’ @ string / continue_label ‘)

Let me start by saying I'm a brand new Android programmer I'm using pragmatic's Hello Android book (3rd Edition) I'm studying a popular Sudoku game example that will be placed in main After copying the code from the XML file, I received the following error:

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 may all be relevant, but after some search, I don't know what the problem is Any suggestions?

Solution

Everything you say wrong You have a res folder where your resources like strings / images / layouts can reside You are referring to resources, but they do not exist You are quoting about_ Label string, but there is no label string about in your string XML_ Label and its value See res - > strings Check all your XML files and put the resources you try to use into the program
