Android. ldpi, mdpi, hdpi clarification
<p>So, in regards to this stackoverflow accepted answer: <a href="http://stackoverflow.com/questions/6930031/how-do-i-convert-ppi-into-dpi-for-android-images">How do I convert ppi into dpi for Android images?</a></p>

<p>So, ok, i make each background image the dimensions that that guy specifies in the answer. 
BUT, if i define the other ImageViews (smaller ones), that are placed on the screen, in relation to the sizes defined above (e.g. let's say an ImageView has dimensions 20x20 for the hdpi devices, if i calculate this dimensions for the ldpi devices, the image would have to be 7x7 pixels, which is terribly small) then the ldpi devices won't be able to see anything on the screen :) Or will they? Am i doing it right, or not?</p>

<p>I'm terribly confused. Can someone clarify this for me please? :)</p>
