Android App demo in Website?

I'm creating a app landing page for my friend.. I want to show the app demo with user interactions, just like they are using it in mobile.. I'm planning to show only few interactions.. For this i can recreate the app in HTML using material framework..
So my question is how can I show that app demo with user interactions??.. It's not going to be complex demo.. Just want to show front page of app and when user clicks on the button then user will go to next screen of the app.. that's all..
How can I do that? Is there any library to do that? Or any other ideas how can I achieve this?
You can use Android Studio to record the screen of any connected device or emulator.

Android CardBoard VR -navigate from one image to another

I am developing a cardboard app which shows all rooms of a house, user is allowed to navigate from one room to another by clicking on a button placed in door of next room.
How to place a button on door of next room and how to change to new-room-image while that button is clicked.
It will be helpful if there is any tutorial or code is shared.
Thanks.
Have you tried implementing the above problem,if so how you are navigation in the VR View as google does not provide any specific implementation for the Google VR SDK for android, the options are only available for Unity and Unreal engine. If you have implemented then it would be helpful if you can share the sample codes.

Using Goggles or Zxing Barcode scanner with a PhoneGap application

I am trying to set up my current app (it's a HTML5 application compiled with phonegap build) where when I press a button, it pops up an option to select which bar code scanner to use(Or prompt to download the bar code scanner). When I select and scan it, I want to retrieve the information.
For example:
Retrieving via Zxing scanner would give me a set of numbers.
Retrieving via Goggles will give me more information like the number and product details.
I have seen some guides which are for native Android where they use Zxing but not Goggles. Seen no guides for using Goggles in an application. Closest I saw is a reverse engineered attempt dated few years back and not for HTML5 plat.
All I need to do is press a button from my app, go out into one of the scanner apps and retrieve the information back to my app to display.
Is there anyway I can do this? Is there a set of APIs available to access Zxing and Goggles via a HTML5/PhoneGap application?
It is definitely possible. Seen it on few applications.
This one for example: An app on Google Play
Please assist.

Voice recordering in Android web view app using Cordova

I am trying to open my web page as Android app. I want to add voice recording functionality using phone microphone in my web app. When a link on web app page is clicked it should start recording and save the recorded file.
After searching its possibility, i came up with "Cordova". But still not able to make it.
Thanks in advance.
I've got a solution for this issue. Web page can be opened in an iFrame and then it can communicate with the app.
Refer example below for using Camera of the device.

It works...:)

How to call android application from web browser

I want to call android application on clicking of button on some website from mobile.
Suppose I am opening one url on android browser and I want to call my application on clicking on button provided by that site. How to do that??
Suppose we are using browser other than Chrome then is it allowing??
If you link to your application as "myapp://foo/bar", can't you use some sort of intent filter to start your application.
I mean, if you press a youtube link in the browser it asks if you want to complete the action with the YouTube app or the browser.
I have seen similar examples regarding Google Maps links (which would open in either browser, google maps(?) or GeoBeagle).
Please take a look at the WebViewDemo. Javascript code in the web page can call into your Activity. As well as the other way around.
You cannot... if the site is being browsed in the default browser (Chrome).
If you already have an application that embeds the WebView, then you can do some bit of handling of - mouse clicks, window alerts, navigation etc. Otherwise, not!
