I want an mobile application in android studio to be able to sell products advertised in instagram.
the users (sellers) must be able to login via instagram id to my [login to view URL] app should display the advertisements posted by the seller in instagram.
basically my app should enable instagram sellers to have safe transactions via my app.
they have to register to my app and then they can sell/buy.
i need the source code,and the resources that will be used.
