Is it possible to transfer data directly between two android devices to other users in the same network?
<p>Let's say I have two android mobile devices, connected to the same wireless network, and that network hasnt external/internet access.</p>

<p>Without third party software, is it possible to transfer data through wifi without knowing the ip from each other and without creating an hotspot? Something like we do on Windows (if 2 pcs are on same network, they can share information directly without internet access)</p>

<p>Starting with the basics, I would like to develop an application, where android phones on same network appears on a list , and then a user choose on of them and writes something - and if the other user have the same app running, appears that on his phone (and then he can reply of course - basically, a chat.</p>

<p>I know this make no practical sense, but believe makes all the sense for what I need to do (it's not a chat of course). If anyone knows anything, please help me - i found nothing.</p>

<p>Thanks in advance.</p>
