Issues while creating App cards for my android app


I am new to creating app cards.I have following doubts:-

I have an android app.I want my app to be launched when the user clicks an app card for it if it is not installed on phone or else direct it to googleplay.

The point is that my app doesn’t have any html/web pages in it.My app queries some data from our server and then my app displays that data using basic android components like activity.

If an app doesn’t have html pages is it not possible to create an app card for it?
If yes then how.I have added scheme in the android manifest.xml.

Please help me its kind of bit urgent.


Sorry, cards must be attached to URLs.

You could create a blogger account or somesuch and include the meta tags there. Then tweet using that URL.

I know that’s not ideal, but it’s an option.
