  1. Download the Android SDK command line tools from here 1. For linux variant, download the following file: tools_r25.2.3-linux.zip
  2. Unzip the file to a folder.
  3. Run the "android" application from the unzipped folder. 1. NOTE: Running the "android" application needs GUI. Running natively on the linux host is recommended or have X11 forwarding. 1. NOTE: When running the "android" app keep note of the SDK path. This will be needed later.

    1. SDK Platform

Install Java

Install the latest version of java, if not already installed.

Install Gstreamer SDK

Install Gstreamer SDK from http://gstreamer.freedesktop.org/download/

Download URL: https://gstreamer.freedesktop.org/data/pkg/android/1.6.0/gstreamer-1.0-android-armv7-1.6.0.tar.bz2

gstreamer-1.0-android-armv7-1.6.0.tar.bz2
  1. Once downloaded unzip the file to a folder.
%>tar xvfj gstreamer-1.0-android-armv7-1.6.0.tar.bz2

Command line build instructions

  1. Clone repository
%>git clone https://github.com/ATLFlight/drone-controller.git
  1. Set up the environment, and install gradle if necessary:
$ source env-setup.sh

  1. Create the local.properties file at the top-level of the dronecontroller git root. This allows gradle to know where the Android NDK, Android SDK and Gstreamer SDK are located. Example:

     gst.dir=<path_to_gstreamer_1.6.0_unpacked_path>
 ndk.dir=<path_to_ndk_r10e_unpacked_path>
 sdk.dir=<path_to_installed_android_sdk_path>

```
**NOTE**: For the "sdk.dir" use the "SDK path" as displayed when running the "android" app as part of the "Install Android SDK" section.
  1. Tell gradle to build the app
$ gradle assemble
  1. The generated apk file will be located at:
<drone_controller_git_root>/app/build/outputs/apk/app-debug.apk

Installation

Use the adb install command to install the apk on the Android Tablet

%>adb install <path_to_dronecontroller_apk>/app-debug.apk

Usage

Refer to UserGuide for DroneController usage information
