Android equivalent of the iPhone's "Add to Home Screen"?

Question

I am developing a mobile web app. Currently I have this snippet of jQuery code which checks if the app is running full screen:

if ( !window.navigator.standalone )
{
    $('#content').before( '<div class="notice">To enjoy the mobile experience to its fullest, tap the arrow button on the toolbar below, choose <b>Add to Home Screen</b>, then launch it from there.</div>' );
}

I have a few questions:

1. Does window.navigator.standalone work on Android phones?
2. What is the process for a user to add a mobile web app to their home screen? I tried looking for browser screenshots but didn't find any reliable sources.
3. Is there an equivalent to iPhone's "apple-touch-icon" link element? Found the answer to this here.

Answer 1

A web application can't run directly on android home screen. for that it need some other customized home screen. right now there are two companies who are working to provide a platform from android to run web application standalone.

• Obigo WRT
• Opera

where you can make your web application as a widget and then it will run in that runtime. currently obigo have provided the customized home screen. where opera will run web widget within an application.
