what i need to design an android App to control outputs & display Values ?

any idea to start with

You can design from scratch but there are much easier solutions. For control applications I suggest using MQTT because it is a standard and available on most platforms, including Android.

Add an MQTTT (pubsub) library to your ESP program and an MQTT client on your Android device, they will talk to each other over WiFi. I use "EspMQTTClient" on ESP8266 and ESP32 devices and on my Android phone and tablet I use "IoT MQTT Panel Pro". With those I can control many devices across several WiFi links and have graphical switches, sliders, meters and other widgets to make it look nice. I also use a Raspberry Pi as the MQTT broker and it also runs "Node Red", giving me mobile access though a cheap 4G dongle and runs a webcam at the same time.

Getting started

Useful resources to get you started with MQTT, the standard messaging and data exchange protocol for the Internet of Things (IoT).

mqtt.org

The connection name is anything you want, it is just so you know which you are using if there are several connections available.
Client ID is used if there are several clients on one broker. Most systems invent an ID for you if you leave it blank.
The broker IP is the IP address of the android device (or any other host) on the network. The client devices need this so they know where to connect to find the broker.
There is usually a port number needed as well, the default is 1883 but you can change it to any available port number. The port number on the broker and all connected devices must match.
