title: Android: Recommendations for background image sizes for different screen densities?
body: <p>Which is the correct sizes of background images for the different densities ldpi, mdpi, hdpi, xhdpi, xxhdpi?</p>
  
  <p>I have transparent background images (.png) and want to reduce image size as much as possible. (not concerning the .apk size, but concerning memory issues on lesser powerful devices)</p>
  
  <p>I assume, the first thing is to make sure the images are in the correct sizes, so that they do not need to be scaled. However, I don't know how the densities relate to certain screen resolutions (if any).</p>
  
  <p>What other options are available to reduce image size . I am using GIMP to create the background images. Which settings should I use in GIMP?</p>
  
  <p>Any recommendations?</p>
  
  <p>EDIT: 
  Should a device with a 800 x 480 pixel screen use a background image of 800 x 480 pixel? 
  Android would not have to scale it, but on the other hand, the image would require a significant amount of memory?</p>
  
  <p>What would be the best resolution?</p>
  
  <p>And how do I know which devices have which screen size? </p>
  
  <p>I.e. the SGS GT-I9000 has 800 x 480, but is a ldpi device (only 233 dpi). </p>
