kdeconnect-kde  1.3.4
About: KDE Connect adds communication between KDE and your smartphone.
  Fossies Dox: kdeconnect-kde-1.3.4.tar.gz  ("inofficial" and yet experimental doxygen-generated source code documentation)  

Some Fossies usage hints in advance:

  1. To see the Doxygen generated documentation please click on one of the items in the "quick index" bar above or use the side panel at the left which displays a hierarchical tree-like index structure and is adjustable in width.
  2. If you want to search for something by keyword rather than browse for it you can use the client side search facility (using Javascript and DHTML) that provides live searching, i.e. the search results are presented and adapted as you type in the Search input field at the top right.
  3. Doxygen doesn't incorporate all member files but just a definable subset (basically the main project source code files that are written in a supported language). So to search and browse all member files you may visit the Fossies kdeconnect-kde-1.3.4.tar.gz contents page and use the Fossies standard member browsing features (also with source code highlighting and additionally with optional code folding).
KDE Connect - desktop app

KDE Connect is a multi-platform app that allows your devices to communicate (eg: your phone and your computer).

(Some) Features

  • Shared clipboard: copy and paste between your phone and your computer (or any other device).
  • Notification sync: Read and reply to your Android notifications from the desktop.
  • Share files and URLs instantly from one device to another.
  • Multimedia remote control: Use your phone as a remote for Linux media players.
  • Virtual touchpad: Use your phone screen as your computer's touchpad and keyboard.

All this without wires, over the already existing WiFi network, and using TLS encryption.

Supported platforms

How to install

This explains how to install KDE Connect on your computer. You will also need to install it in your phone and pair both devices in the app if you want it to be any useful.

On Linux

Look in your distribution repo for a package called kdeconnect-kde, kdeconnect-plasma, or just kdeconnect. If it's not there and you know how to build software from sources, you just found the repo :)

If you are not using Plasma 5, you might want to install a user interface for your platform. The indicator-kdeconnect project provides an appindicator icon plus integration with Nautilus.

On Mac or Windows

Platforms other than Linux are not officially supported, but it should be possible to run KDE Connect there. You can compile KDE Connect for Windows using Craft and it works except for some plugins. I haven't tried on Mac. Contributions welcome!

On BSD

It should work, but no promises :)

How does it work?

KDE Connect consists of an UI-agnostic "core" library which exposes a series of DBus interfaces, and several UI components that consume these DBus interfaces. This way, new UI components can be added to integrate better with specific platforms or desktops, without having to reimplement the protocol or any of the internals. The core KDE Connect library is also divided in 4 big blocks:

  • LinkProviders: Are in charge of discovering other KDE Connect-enabled devices in the network and establishing a Link to them.
  • Devices: Represent a remote device, abstracting the specific Link that is being used to reach it.
  • NetworkPackets: JSON-serializable and self-contained pieces of information to be sent by the plugins between devices.
  • Plugins: Independent pieces of code which implement a specific feature. Plugins will use NetworkPackets to exchange information through the network with other Plugins on a remote Device.

The basic structure of a NetworkPacket is the following:

{
"id": 123456789,
"type": "com.example.myplugin",
"body": { },
"version": 5
}

The content of the "body" section is defined by each Plugin. Hence, only the emisor and receiver plugins of a given packet type need agree on the contents of the body.

NetworkPackets can also have binary data attached that can't be serialized to JSON. In this case, two new fields will be added:

"payloadSize": The size of the file, or -1 if it is a stream without known size.
"payloadTransferInfo": Another JSON object where the specific Link can add information so the Link in the remote end can establish a connection and receive the payload (eg: IP and port in a local network). It's up to the Link implementation to decide how to use this field.

To contribute patches, use KDE Connect's Phabricator. There you can also find a task list with stuff to do, and links to other relevant resources. It is a good idea to also subscribe to the KDE Connect mailing list.
