本文详细解释了不同屏幕密度(ldpi、mdpi、hdpi)的概念及其对应的像素密度，并介绍了nodpi资源类型，帮助开发者更好地理解如何为不同设备适配图片资源。

ldpi : Low-density screens; approximately 120dpi.
mdpi : Medium-density (on traditional HVGA) screens; approximately 160dpi.
hdpi : High-density screens; approximately 240dpi.
nodpi : This can be used for bitmap resources that you do not want to be scaled to match the device density.

There is thus a 4:3 scaling factor between each density, so a 9x9 bitmap in ldpi is 12x12 in mdpi and 16x16 in hdpi.
