Android: Multiple Image Density support - scale height width and dpi?
<p>I have an android app that I'm trying to add support for different densities, screen sizes, etc.  I've developed the app on the simulator with the HVGA support and used all icons from our iphone app which turns out nice since the resolution was at 320x480.  Everything looks good now but I'm a bit confused after reading the official android documentation.  For layouts I'm going through and ensuring everything is in dp units but when it comes to the images I'm lost.  I know that mdpi is 160 but what do I tell my designer for what the hdpi image needs to be?  Do we need to increase the height and width and the dpi?  Or is it simply enough to leave the dpi as is and increase the height width?  For example, if I have an image that's 100 x 100 with 160 dpi, in order to render it identical on an hdpi screen it should now be 150 x 150 with 240 dpi?  Assuming if I leave the dpi at 160 it will just be a little blurred?  Sorry about silly question but I just want to make sure I'm doing everything right and I'm really a C developer with no graphics experience at all.... No excuse at all but could use some help.  I saw some examples where the splash screen for mdpi was 320x480 at 160 dpi but then the hdpi splash screen was at 480 x 800 at 240.  Obviously 480 x 1.5 does not equal 800.  Furthermore, after looking at the icons in the android sdk, they only scale up the width and height, not the dpi.  Probably because they're icons and don't need to be?  Lost in photoshop land....</p>
