title: Questions regarding drawable folders for Android
body: <p>Dear StackOverflow users,</p>
  
  <p>I found a of information about what Drawables to use (HDPI, MDPI, LDPI) on StackOverflow. Currently I am using only the HDPI folder. My ImageButtons are 72x72. According to Eclipse, looking at the Graphical Layout of the .XML file, the smallest screen (2.7 IN QVGA) can show all buttons.</p>
  
  <p>If I am correct, Android will scale down the images if someone with MDPI or LDPI screen uses the APP, right? Is there also a setting wherein all different DPI sizes use the 72x72 image? And should I specifically define in the Android Manifest what DPI's are supported? Or when I leave this empty, will it support all possible devices?</p>
  
  <p>Thanks in advance for any answers!
  (Maybe (parts) of these questions are already answered, but there is so much stuff found by google regarding this)</p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I found this for my android manifest file. Would this make it work on all devices? And scale down the HDPI images?:</p>
