Hi im a mobile/web developer, have been doing this since 4-5 years now, i have massive experience in Android, i build apps with great UI/UX and best practices in mind, for your project i think it can easily be done by scraping the dom to get the data u want, it wont take me a day if u want the user to open his facebook account in your application, leme know how u want it, this can be easily done, looking forward to working on this. if u have any questions we can have a discussion in chat, thanx
