AndroidMultiVNC

This README mostly contains technical information about MultiVNC for Android.

Building the Android Version

To prepare the source tree, do the following in the root of the repository:

  • git submodule update --init
  • ./prepareLibreSSL.sh

After that setup step, simply fire up Android Studio and build the app from the android directory.

Technical Notes

Supported URL Schemes

  • vnc://host:port

I/O Architecture

  • MainMenuActivity

    • launches VncCanvasActivity

  • VncCanvasActivity

    • contains VncCanvas, which is a GLSurfaceView
    • contains UI buttons, ZoomControls
    • contains PointerInputHandler
    • creates a new VNCConn, connects it with the VncCanvas and sets it up from a ConnectionBean

  • VNCConn

    • encapsulates the native rfbClient, allows querying info from it as well as triggering actions
    • facilitates threaded input/output

  • InputHandler

    • gets scaling from VncCanvas
    • sends pointer events (from touch, gestures, mouse, stylus) to VncCanvas

  • VncCanvas

    • receives touch/motion events from system, pipes them to InputHandler
    • receives pointer events from InputHandler, pipes them to VNCConn
    • receives key events from VncCanvasActivity, pipes them to VNCConn
    • draws a VNCConn's rfbClients's framebuffer
      • OpenGL setup and drawing is done in managed code
      • framebuffer data is bound to texture by native code
    • contains some UI as well (Toast and Dialog)

  • Framebuffer Abstractions

    • none, framebuffer completely resides in native part
