Drawable resources include bitmaps and NinePatch (stretchable PNG) images. They also include complex composite Drawables, such as LevelListDrawables and StateListDrawables that can be defined in XML.

Both NinePatch Drawables and complex composite resources are covered in more detail in the next chapter.

All Drawables are stored as individual files in the res/drawable folder. The resource identifier for a Drawable resource is the lowercase file name without an extension.

The preferred format for a bitmap resource is PNG, although JPG and GIF files are also supported.
