Cross-platform text, image, video Chat for Android, iOS and Web using Firebase/Parse/PubNub -

-

i want develop cross platform chat application can use send text,url,image,location,video friends can on android/ios/web.

i want chat realtime, , want make sure if user not using application, 'notification' new incoming chat message.

how using firebase or parse or pubnub? if not possible, can explore possibility of using them in combination.

notes / problems: 1. firebase: has 'firechat' web, 'firechat/swiftchat' ios , 'chat' android. how synchronize them each other?

  1. pubnub has limitation of sending 32kb in 1 message.

  2. i read few places parse not support realtime chat?

i tried searching different questions here already, did not find solution satisfy requirements (in bold). also, not asking opinion better here, hope question fits stackoverflow.

thanks

use pubnub realtime chat. there sdks platforms listed. images, send/receive data image url, while storing images using parse.

as long use same credentials (your pub/sub keys) publish messages same channel, messages synced no matter platform users on.

for push notifications, should able use either pubnub or parse.

if need map user locations in realtime, try eon pubnub too. http://www.pubnub.com/developers/eon/
