This project implements an X11 server for use with Android devices, written in Java. The X11 server runs within an Android View subclass, allowing it to be embedded in other applications. This implementation has proven to be very useful for porting C++ FLTK applications to Android.

This project also includes a simple demo application.

Quick Start

To display programs within the X-Server demo app you need to set the DISPLAY environment variable on your host device. Its also highly recommended to use a window manager (i.e. lwm). A simple window manager (FLWM) is already embedded into the application. For an extended softkeyboard Hacker's Keyboard can be used.

Build

Gradle

This project uses gradle build system, so if you don't want to mess with Android Studio you can just open console at project's root folder and type ./gradlew build. Generated APK can be found under app/build/outputs/.

Manual (Makefile based)

If, for whatever reason, you do not want to use gardle, there is also a Makefile that performs all the necessary build steps.

Example

Starts xfe file browser, 192.178.1.2 should be replaced with te IP of your device:

$ export DISPLAY=192.178.1.2:0
$ lwm &
$ xfe

In addition to the touch screen, the volume rocker acts as mouse buttons.
