I want to stream video from android device to some computer is that possible?
We recommend using the WebRTC for video streaming as PubNubs message limit is 32kb. See more here: http://www.pubnub.com/developers/demos/webrtc/
Ok, thanks! Another question is: Can I order which camera shall my android device use if I have back and front camera? (by default front is in use)
That wouldn't be something PubNub would do, but this stackoverflow question may help.
