title: Android minSdkVersion
body: <p>I've programmed my app with Eclipse and android 2.2. However I think that my app would work for previous version and so it would allow more users to use my app. The problem is that I'm not sure... for instance I'm using Gestures which I think is a more recent feature... but otherwise I'm just using some Button, ListView, and WebView.</p>
  
  <p>So is there a way to detect automatically the Minimum Sdk Version needed ( by checking which function my app is using) ?</p>
  
  <p>I can't download the SDK of each previous version of android and test it until it doesn't work ...</p>
  
  <p>Thanks</p>
