An Android/Linux ground controller in Scala

This project began with the goal of having an Arduplane follow a hang-glider and take pictures. That work still continues (see the posixpilot subproject). However, it quickly became apparant that much of this software could be used to make an Android based Ground Controller.

A prebuilt version of the Android application is on the Play store. If you are not interested in coding, you probably want to go there.

Credits

  • Mavlink compiler and library kindly created and donated by Guillaume Helle (antispamprefixremovemeghelle31@gmail.com). If you would like to use this code in your own project, the source is located in the mavjava directory.
  • Copter-gcs provided the nice HUD display code
  • Wiki documentation mainly by Peter Meister
  • Most icons by Scott Berfield
  • Danpe made maps more reliable
  • Mission Motors Inc. kindly open source the tiny HTTP server we now embed into the application
  • Pieter@Diydrones bought me a bluetooth serial adapter to test with
  • Thanks to Robert W, Earl C, Jack O, Linux P, Anthony G, Robert L, Jeremy Z and Rana for donating so I could buy a gaming tablet. Not yet purchased, but without their prodding I wouldn't have gotten around to adding gamepad support for a while...

How to build

Stuff you need to install

To build this project you need the following preinstalled:

Step by step build instructions

These instructions are slightly involved because the android-sbt plugin I use has some local improvements I've made that haven't yet been integrated into the standard release binary. Please bear with me (and fix this README/send pull-requests when you find errors)

Basic setup

First make sure we have the android tools and libraries.

~$ mkdir development
~$ cd development/
~$ export ANDROID_SDK_HOME=/home/kevinh/Packages/android-sdk-linux/ ( or wherever you installed it)
~$ export PATH=$PATH:$ANDROID_SDK_HOME/tools (to make the next line work,tools has to be on the path)
~$ android ( should launch the android manager application, make sure that you have the android and google version 17 libraries installed )

SBT will end up asking you to fetch the version of software we use, might as well just fetch it now instead...

~/development$ wget http://typesafe.artifactoryonline.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.12.1/sbt-launch.jar
Resolving typesafe.artifactoryonline.com (typesafe.artifactoryonline.com)... 23.20.223.55

Saving to: `sbt-launch.jar'
...
~/development$ mkdir -p ~/.sbt/.lib/0.12.1
~/development$ mv sbt-launch.jar ~/.sbt/.lib/0.12.1

Now we need to build and install a slightly tweaked version of the sbt android plugin.

Get it...

~/development$ git clone git://github.com/geeksville/android-plugin.git
Cloning into 'android-plugin'...
remote: Counting objects: 2510, done.
...
~/development$ cd android-plugin/

Build it...

~/development/android-plugin$ sbt

> (ctrl-d)
~/development/android-plugin$ cd ..

Building Andropilot

The following should 'just work' if you've done the previous steps.

First we get the repo.

~/development$ git clone git://github.com/geeksville/arduleader.git
Cloning into 'arduleader'...
remote: Counting objects: 1957, done.
...
~/development$ cd arduleader/

Then we pull in a library of android utilties.

~/development/arduleader$ git submodule init
Submodule 'scandroid' (git://github.com/geeksville/scandroid.git) registered for path 'scandroid'
~/development/arduleader$ git submodule update
Cloning into 'scandroid'...
remote: Counting objects: 104...

Now we start the sbt build tool and have it build a test desktop app (uses most of the andropilot code, but runs as a desktop ground controller). This is useful to test our build before trying to do the android stuff.

~/development/arduleader$ sbt
Detected sbt version 0.12.1

If the previous step says success your basic build environment is okay. Now lets try android. First we need to install some google stuff (I haven't figured out how to reference it any other way - this is a 'one time' step).

> project google-play-services
> publish-local

Now you can try building our app (this is what you'll rebuild as you make changes)

> project andropilot
> android:start-device or android:start-emulator
...
Dexing /oldroot/home/testuser/development/arduleader/andropilot/target/classes.dex
Packaging /oldroot/home/testuser/development/arduleader/andropilot/target/andropilot-0.1.2.apk

Done! You should now have the app running on your USB debugging connected tablet. For debugging with the 3dr module attached, I recommend installing one of the ADB over Wifi applications (search for "adb wifi" on the play store).

Working with eclipse

If you would like to use eclipse, then type "eclipse" at the sbt prompt to autogenerate the project files. Then go into eclipse and import all of the project directories in this tree.

Making Google Maps work

To enable Google Maps after compiling you'll need to generate a new key and replace that key in the manifest. Please follow Installing The Google Maps Android V2 API The default location of the auto generated debug.keystore is at SDK_LOCATION/.android/debug.keystore

You can’t perform that action at this time.
