I developed and designed Android app in TBM. I developed a complete Login, Registration system in Java, XML, and JSON. Once you login app, It will send you to welcome username activity. I designed the logo of the company on photoshop. I used MySql database to save user profile. I made editable IP address so that I can connect with a different network. I write the code for Wifi connection. I wrote code for the different label, text box, button, image, background. I applied timer, progress bar. I connected all the activities. After completing Android app, I connected with hardware for that I wrote client-side code to detect the IP address of hardware. I used hardware Arduino with an embedded system. I wrote server side code on Android app to communicate with hardware. I uploaded client side code on hardware. I developed Android app to control and work with Robot machine. Robot produces UV light on the floor to kill bacteria. My application is used in many hospitals, transit systems like TTC and libraries.
