问题
I am connecting different devices with wifi hotspot AP programatically in my android app, How can i detect the clients being connected and disconnected and to the wifi hotspot AP i turned on programmatically ? Is there any callback event in Android API to give information regarding the connection or disconnection events of individual devices ? Thanks in advance.

I think you need to use WifiP2pDevice
There you can check for available devices, and also if they are connected or not.
Try looking here at the available methods here
EDIT:
This Android Wifi Hotspot Manager Class have sample code to scan /proc/net/arp and ping each known client to detect livelihood.
You can implement that logic in a loop to emulate a Wifi Client disconnect event from driver.
