Grouping Resource Types

You should place each type of resource in a specific subdirectory of your project's res/ directory. For example, here's the file hierarchy for a simple project:

MyProject/
    src/  
        MyActivity.java  
    res/
        drawable/  
            icon.png  
        layout/  
            main.xml
            info.xml
        values/  
            strings.xml  

As you can see in this example, the res/ directory contains all the resources (in subdirectories): an image resource, two layout resources, and a string resource file. The resource directory names are important and are described in table 1.
