I was working on Android 1.5, but I have now moved to the latest version. So there is only one "drawable" folder in Android 1.5, but now there are three different folders for storing images in the Android project.
And I have found some articles for these three folders that says
- hdpi means High-dpi
- mdpi means medium-dpi
- ldpi means low-dpi
But what is the exact purpose of these three folders and when should I use a particular folder to store images in?

To declare different layouts and bitmaps you'd like to use for the different screens, you must place these alternative resources in separate directories/folders.
This means that if you generate a
200x200
image forxhdpi
devices, you should generate the same resource in150x150
forhdpi
,100x100
formdpi
, and75x75
forldpi
devices.Then, place the files in the appropriate drawable resource directory:
Any time you reference
@drawable/awesomeimage
, the system selects the appropriate bitmap based on the screen's density.
