All visitors from Android to joomla3.2 site should be shown a message to download Android App

[Ramji Goyal]

I have a joomla 3.2 site and also have a android app for my site. Now, i want a suggestion system such that when anyone browse any page of my site from android device, it should display a popup, suggesting that please download our android app.

There should have two options 'download' and 'cancel'. If user clicks on cancel then it should not display this popup message on any page. And if user clicks on 'download' then he should be redirected to Play-store

Please suggest me some ideas for this and which plugins or libraries i have to use for this How i can do this?
