Android Mobility Tracker application

Hello world. I have an android project needed to be done. This is not a Commercial project, it's a educational project which be used in educational research. This is a Mobility Tracker application detailed below: 1- Application let users create new account or login by previous account. 2- Application is tracking user movements all the time, walking, running, ... . 3- Application counts steps and record it, if is bigger than 50 (movements fewer than 50 steps should not be recorded on database) 4- For each mobility event application also records Mobility Type (walking or running), the GPS coordinates of where mobility event started, the GPS coordinates of where mobility event finished, average speed of movement during event, start time, start date. 5- Application shows Mobility Events on Google Maps (internal inside application itselfs) I have attached a sample Exel file of sample database. Something to show you what I have in my mind. Just notice that user_id also must be added to this sample database, I forgot that :) It's your decision to use what kind of database, as long as you are able to host that on my Ubuntu server with nginx and VestaCP.
