I need a Android Developer who can code a chat app for android.
You are free to use any SDK available on internet.
I have looked around and found that quickblox.com provide a decent SDK with cool feature for the chat app.
Before sending me PM, please check quickblox or any other SDK provider with whom you are comfortable. And if you want to go with other SDK provider, please mention its name and functionality that SDK is providing. In case you want to go for development of the app from scratches then please mention this in the PM.
Let me know if you have done chat app previously.
