Anybody knows how to use audio functions/library to communicate with other android device using streaming and a server? I know that there is a "walkie talkie" (this tutorial by Erel -> https://www.b4x.com/android/forum/t...reaming-over-wifi-or-bluetooth.30648/#content) - but it's very difficult or even impossible in some networks to create a direct socket with other peer thru internet. A server solution using, for example, php streaming between two android devices could be the ideal solution always, with the bonus of gaining control and visibility over the peers - the basis of a professional communications service... does anybody knows how to do this ? (streaming client/library + php streaming server ?). Thanks!
