title: Android screen size HDPI, LDPI, MDPI
body: <p>I have a background that I need fit in all screen sizes. I have three folders, <code>hdpi</code>, <code>ldpi</code> and <code>mdpi</code> for drawables, but in the emulator there isn't any referense to what resolution  <code>hdpi</code> is and what <code>mdpi</code> and <code>ldpi</code> are.</p>
