unable to get the changes made in index of phonegap android

I'm unable to get the changes made in the index of PhoneGap Android. Actually I have added everything into my eclipse 开发者_如何学编程android project with phonegap. When i change that index.html page, I'm not getting the changes in emulator. Those changes are not reflecting in the emulator. It is remaining with same page like Helloworld.

After making the changes to index.html, you need to select its enclosing project and choose Run As -> Android Application from the right click menu.
