Send/Receive data on Arduino Mega2560 through ESP8266 to Android App

Using Arduino Project Guidance

Hi,

I’m trying to find out how I can send/receive data to and from a Arduino through ESP8266 to Android app and vice versa. Android app will be use to read real time sensor input data and also be used to toggle accessories on/off

Surely an interesting project.
