Wrtting a messenger app for Android;

[mut]

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.

Hi!

You can also have a look at V-Play Engine for mobile apps and games. It includes a chat service which allows to create your own cross-platform messenger with a few lines of code:

import VPlay 2.0
import VPlayApps 1.0
 
App {
 
 // app navigation
 Navigation {
   NavigationItem {
     title: "User Profile"
     icon: IconType.user
     NavigationStack {
       initialPage: socialView.profilePage
     }
   }
 
   NavigationItem {
     title: "Chat"
     icon: IconType.comment
     NavigationStack {
       initialPage: socialView.inboxPage
     }
   }
 }
 
 // service configuration
 VPlayGameNetwork {
   id: gameNetwork
   gameId: 285
   secret: "AmazinglySecureGameSecret"
   multiplayerItem: multiplayer
 }
 
 VPlayMultiplayer {
   id: multiplayer
   appKey: "dd7f1761-038c-4722-9f94-812d798cecfb"
   pushKey: "a4780578-5aad-4590-acbe-057c232913b5"
   gameNetworkItem: gameNetwork
 }
 
 // social view setup
 SocialView {
   id: socialView
   gameNetworkItem: gameNetwork
   multiplayerItem: multiplayer
   visible: false // we show the view pages on our custom app navigation
 }

import VPlay 2.0
import VPlayApps 1.0

App {

 // app navigation
 Navigation {
   NavigationItem {
     title: "User Profile"
     icon: IconType.user
     NavigationStack {
       initialPage: socialView.profilePage
     }
   }

   NavigationItem {
     title: "Chat"
     icon: IconType.comment
     NavigationStack {
       initialPage: socialView.inboxPage
     }
   }
 }

 // service configuration
 VPlayGameNetwork {
   id: gameNetwork
   gameId: 285
   secret: "AmazinglySecureGameSecret"
   multiplayerItem: multiplayer

 VPlayMultiplayer {
