Write android App with location and Social media services

Dear developer, I would like to have an android app made that, with the press of a button, gets the users location and posts that to his or her social media account (Facebook, twitter) with a pre-set message. What's important is that the user has to log in via social media and that the app only has to request permission for the users location just once, when it is opened for the first time. This location should be converted to a readable address and posted to their social media instantly. If the user has multiple social media accounts, the address and message should be posted to all of them. In addition, the user should be able to send SMS (text) messages to some chosen contacts automatically when the same button is pressed. The whole program should be made with Android Studios and the project file sent to me upon completion for testing and publishing. More detailed information will be provided if you are chosen for the project. A non-disclosure agreement will have to be signed by the chosen developer. The fee can be discussed but all everything will have to be done through freelancer. If you're interested in the job, please send me a motivational e-mail and 1 - 3 examples in your portfolio, preferably android apps that use geolocation services and social media implementation.
