Project Description:
i need you to modify the opensource mobile app based on jabber, it is for both android and iOs and its full open source.
backend server already installed(openfire server XMPP). basically i need you to:
1. modify the layout to make looks like usual IM(whatsapp,line,wechat)
2. make the apps running in the background. (now the apps only running in background for 10 minutes because of this
3.Ability to register for everyone
4. push notification is also already in source code.. so i need my app have this too.
