title: Working of android drawable folders categories
body: <p>I am testing on Samsung galaxy tab 3 with dimensions are 1024 by 600. size is 7 inches.</p>
  
  <p>i created following folders.</p>
  
  <pre><code>drawable-ldpi
  drawable-mdpi
  drawable-hdpi
  drawable-xhdpi
  drawable-xxhdpi
  </code></pre>
  
  <p>i checked dpi of my device using this link <a href="http://dpi.lv/#1024" rel="nofollow noreferrer">http://dpi.lv/#1024</a>×600</p>
  
  <p>My device have 170 dpi(dots per inch).</p>
  
  <p>when i run my project. Image in drawable-mdpi folder is triggered by my device. </p>
  
  <p>I took following image from tutorial i am following.</p>
  
  <p><a href="https://i.stack.imgur.com/wGloF.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/wGloF.png" alt="enter image description here"></a></p>
  
  <p>According to tutorial image is fetched from correct folder i.e drawable-mdpi (2. Medium Density)</p>
  
  <p>Now my question is:</p>
  
  <p>With regards to size Android have four categories of devices.
  small, normal, large, xlarge </p>
  
  <p>Lets take large size category. (my 7 inches device comes under large size)
  Large size category can be of any from following types.</p>
  
  <p>1) large size with 100 to 130 dpi(dots per inch)</p>
  
  <p>2) large size with 120 to 180 dpi(dots per inch)</p>
  
  <p>3) large size with 180 to 280 dpi(dots per inch)</p>
  
  <p>4) large size with 280 to 360 dpi(dots per inch)</p>
  
  <p>It is ok. android will trigger images from corresponding drawable-&lt;--dpi> folders.
  But we have kept different size images in all drawable-&lt;--dpi> folders.</p>
  
  <p>As in my case i kept small size image in drawable-mdpi.But my tablet screen size is 7 inches. </p>
  
  <p>so it is triggering image from drawable-mdpi. which is very small for a 7 inches screen.</p>
  
  <p>what is correct way to use it.
  do i have to create folder like :</p>
  
  <pre><code>drawable-large-mdpi
  drawable-large-ldpi
  drawable-large-hdpi
  drawable-large-xhdpi 
  </code></pre>
  
  <p>and so on.</p>
  
  <p>Please explain this.</p>
