docs: <p>This method will allow you to pass in literal strings. You must wrap the string in single quotes in order to ensure it is not modified
  by Android. Android will try to coerce the string to a float, Integer, etc., if it looks like one.</p>
  <p>Example: <code>&lt;meta-data android:name="sdk_distribution" android:value="'1.00'"/></code></p>
  <p>This will evaluate to a String "1.00". If you leave off the single quotes, this method will just cast to a String, so the result would be a String "1.0".</p>
