If i turn my android device to a portable hotspot and connect some devices to it, Is it possible for me to Broadcast/Multicast data to devices connected from my Device (i.e. from Hotspot)? If Yes, How?
A snippet in Android would be great!
Thanks in Advance
Yes,you can multicast or broadcast udp packet in hotspot

I need some clues how to approach my app. I have android device which provides HotSpot/AccessPoint for other devices. And this device which provides hotspot for others wants to get some data from internet and broadcast this data to devices which are connected to this hotspot. Ofcourse all smartphones must have installed same app.
Is there way to achieve that?
Thanks You!
I want to create an android application.
Is it possible to send a notification from my phone to other phone which has enabled its WiFi hotspot.
I mean, one phone has enabled its WiFi hotspot and I scanned available WiFi devices and I saw its WiFi hotspot ssid at my available wifi list and I want to send a notification or a message without connect its wifi hotspot point, or using bluetooth or using internet.
Is it possible?
There is also NFC - Near Field Communication. It has nothing to do with Wifi though.
So in theory, yes, I believe you can do what you asked. I think you can react to the presence of the other phones Wifi hotspot, but communicate on NFC instead.
As for sample code, I can't help you. I haven't written anything using NFC.
There is also sms or a phone call
Android Wear devices use bluetooth to connect to the internet, via your smartphone.
Does this mean the Smartwatch has its own IP on the local network?
Probably too late to reply but yes android wear devices do indeed have their own IP.
One way to find out is to debug over wifi under dev options. Once connected correctly, it should display its IP on the network with port 5555.
Alternatively, disable Bluetooth on the device, enable wifi and scan the network. Android wear favours Bluetooth connectivity so its important to disable it.
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.
I am developing one Android application which communicate with Wifi network. I want to know the name of the wifi socket in Android Device. i searched in google but nothing help me. I heard android device used RFCOMM socket for Bluetooth communication. Is RFCOMM socket used for Wifi communication?
