title: making fonts get larger on larger screens
body: <p>I have searched Stackoverflow and google and what I find is answers for people who want fonts to remain the same size but I want them to get bigger when the screen gets bigger.</p>
  
  <p>Specifically, I want very large fonts in my application.  On my phone, they are 1/2 inch high - perfect.  My problem is that on my 7 inch tablet they are also 1/2 inch high and I want them to scale up and be about 1 inch high.  I have tried sp and dp modes and both just keep the fonts the same physical height, which is not what I want. I see there is something new for tablets with 3.2 and higher but I want to support devices from 2.3 and higher.  I have seen complex code that says it auto scales fonts to fit the text in a width but that is not what I need.  I want the fonts to be the equivalent of say 100sp on a phone and 200sp on the tablet.  I have no graphics and simple relative layouts with very few elements on the screen.  I just need to make a couple of the textsizes larger for large screens.  I would think it would be simple but I can't find it.</p>
  
  <p>Here is a typical text view entry</p>
  
  <pre><code>    &lt;TextView
      android:id="@+id/textDistance"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_below="@+id/labelDistance"
      android:layout_centerHorizontal="true"
      android:text=""
      android:textAppearance="?android:attr/textAppearanceLarge"
      android:textColor="#ffffff"
      android:textSize="100sp" /&gt;
  </code></pre>
  
  <p>Is there a relatively simple straight forward way to do this?</p>
