title: How to open an app from web on Android
body: <p>I create 'iframe' element, use the http scheme to open an app on Android Device, it works fine if the app is installed.</p>
  
  <p>When the app is not installed, I use <code>setTimeout</code> function setting <code>window.location = marketurl</code>,
  it will open market, and it works fine on <em>Android Browser</em>, but it doesn't work on <em>chrome 25+</em>.</p>
  
  <p>I only see an error message in my browser.
  What should I do?</p>
