Build me an android app with sentiment analysis

Hello, I need a simple android application (much similar as OLX) with Firebase as Database and at the end The Profiles which have High rating should be on HomePage (High rating profiles are on top and Low rating Profiles are in the end of HomePage) with Help of Sentiment Analysis. The application is very simple, you should make clones of other similar applications i've no problem with that. All you have to do is making the application in same sense as High Rated profiles are on top, this functionality should only done with Sentiment Analysis. You have to make application with Java and XML but sentiment Analysis would be in any other language as you love to do. Other Details should be provided in chat, Thanks
