在联系人列表中显示我的应用程序的图标

Question

I just finished the development of my app in android. It has integration with contact list. Now i want to add my app icon in contact list of phone like Facebook, Google and Whatsapp icons. For the contacts that are registered to my app i wish to display my app icon on the contact list next to that particular contact name. Clicking on the app will redirect me to my app.

I have a faint idea that it maybe done by contact provider. I also know this maybe achieved by being able to add my application to the settings->accounts. But i do not know how to do it.

I have already gone through these similar questions but none of them provide adequate answers. How to add custom app tag in native android contact app?
