I had already executed Hello World apk on Android wear emulator, now I want to use HTML inside asset folder to execute it in wear emulator but I am not getting any success
Android wear supports only Java application not to render HTML document. Please refer to https://developer.android.com/training/building-wearables.html for Android were app in details.
It does not work like you are used to from normal Phonegap/Cordova yet. But as you can use a full Chrome Browser on the watch (like com.appfour.wearbrowser) I think it can be done! So what you need to do is fork Chrome on Android Wear and let it launch your website...
For simple HTML, our Android HTML software renderer should work, see https://github.com/kobjects/htmlview
