Hello;

I want to write a messenger app (similar to WhatApps) for Android.

1. The entire message is made of:
- 50 words user data up to a maximum of 10 x 50 words, and
- 100 lines from a file of control data (xml file)
, all of this sent in the same network message from one Android device to the other.

2. The sender is periodically (every second) sending a very small message of 100 characters from sender - receiver for handshaking,....

What are the best protocol and APIs to use to do that in Qt mobile?

Thanks;

Mut.
