Directory structure for flavor-specific resources

Different flavors of application builds can contain different resources. To create a flavor-specific resource make a directory with the lower-case name of your flavor in the src directory and add your resources in the same way you would normally.

For example, if you had a flavour Development and wanted to provide a distinct launcher icon for it you would create a directory src/development/res/drawable-mdpi and inside that directory create an ic_launcher.png file with your development-specific icon.

The directory structure will look like this:

src/
  main/
    res/
      drawable-mdpi/
        ic_launcher.png  <-- the default launcher icon
  development/
    res/
      drawable-mdpi/
        ic_launcher.png  <-- the launcher icon used when the product flavor is 'Development'

(Of course, in this case you would also create icons for drawable-hdpi, drawable-xhdpi etc).
