Write an Android application

I need an android application that basically connects to a specific IP (In this case it's the IP of an ESP8266) on the wifi network and does the following things: (ESP8266 is a server) 1. Connects to the IP after connect button is pressed and stays connected until disconnect button is pressed. After connecting to the server it should go to the 2nd screen. 2. After disconnect button is pressed come back to the first screen after disconnecting from the server. 3. I have attached the app design so please refer to that. 4. When the app is connected to server the server sends current time to the app in a JSON like this: {"function":"read","HH":"12","MM":"48"} This value is displayed on the bottom of the screen. 5. The drop down menu will have these options: a. Set clock b. Set Start Time 1 c. Set Stop Time 1 d. Set Start Time 2 e. Set Stop Time 2 6. The user can choose the time for the above-selected option from android's stock time picker (24-hour format) 7. When send button is pressed the app sends a JSON to the server which is like this: {"function":"Set clock","HH":"22","MM":"45"} or {"function":"Set Start Time 1","HH":"22","MM":"45"} or {"function":"Set Stop Time 1","HH":"22","MM":"45"} or {"function":"Set Start Time 2","HH":"22","MM":"45"} or {"function":"Set Stop Time 2","HH":"22","MM":"45"} Here, function is the option selected from the drop-down list. The value of HH and MM is the hours and minutes respectively chosen from the time picker. If set clock function JSON is sent then a reply like {"function":"read","HH":"12","MM":"48"} will come from the device that needs to be displayed at the bottom as current time as shown in the design. For reducing your effort I have attached an Android studio project of an earlier app that I built. You should use that exact same flow for making and maintaining a connection. I would prefer someone from Delhi-NCR region.
