title: Android graphics for XXHDPI
body: <p>I'm about to adjust all drawables for an Android app for XXHDPI devices (like sony xperia Z and samsung s4). After thorough reading on Google's documentation, blogs, and SO, I'm confused as to the graphics I'm about to produce.</p>
  
  <p>My concerns are the following:</p>
  
  <ol>
  <li><p>Google <a href="http://developer.android.com/reference/android/util/DisplayMetrics.html#DENSITY_XXHIGH" rel="nofollow noreferrer"><strong>states</strong></a> that I shouldn't worry about this density as it scales up XHDPI  graphics - In the same manner, (before XXHDPI devices) why the production of XHDPI graphics was a necessity and it didn't scale up HDPI graphics?</p></li>
  <li><p>Sony <a href="http://developer.sonymobile.com/2013/03/07/make-sure-your-app-does-not-exclude-xxhdpi-screens/" rel="nofollow noreferrer"><strong>reminds developers</strong></a> not to exclude XXHDPI screens without clarifying if this concerns making adjustments to graphics - Do I have to redesign all graphic elements for XXHDPI?</p></li>
  <li><p>Based on (2), Sony Xperia Z Ultra has 342dpi density but it is categorized as an XXHDPI device. - If I produce the graphics for an XXHDPI, which is twice the size of an HDPI density, the graphics will scale down by almost 1/3 to match Sony's density and this is undesirable. Why doesn't Xperia Z use the XHDPI drawables? What if I have a pattern and I can't afford any scaling since I'll lose the detail of the pixel-perfect pattern?</p></li>
  <li><p>Are XXHDPI resources REALLY necessary?</p></li>
  </ol>
  
  <p>I hope somebody can answer all the questions above.</p>

  <p><strong>EDIT</strong></p>
  
  <p>Below are the results of slightly scaling a graphic to adjust to various densities</p>

  <p>The detail loss is obvious at 2nd and 3rd image.</p>
