MAGE Android


This is the MAGE client for Android devices.


Depends on the MAGE Android SDK.


The Mobile Awareness GEOINT Environment, or MAGE, provides mobile situational awareness capabilities. The MAGE app on your mobile device allows you to create geotagged field reports that contain media such as photos, videos, and voice recordings and share them instantly with who you want. Using the GPS in your mobile device, MAGE can also track users locations in real time. Your locations can be automatically shared with the other members of your team.

The app remains functional if your mobile device loses its network connection, and will upload its local content when a connection is re-established. When disconnected from the network, MAGE will use local data layers to continue to provide relevant GEOINT. Data layers, including map tiles and vector data, can be stored on your mobile device and are available at all times.

MAGE is very customizable and can be tailored for you situation.

MAGE Android was developed at the National Geospatial-Intelligence Agency (NGA) in collaboration with BIT Systems. The government has "unlimited rights" and is releasing this software to increase the impact of government investments by providing developers with the opportunity to take things in new directions. The software use, modification, and distribution rights are stipulated within the Apache license.

How to Build

These instructions are for *nix operating systems. Do not use Windows systems to build MAGE. The following example commands are for debian based linux systems like Ubuntu.

You will need to install the Java and Android sdks to build MAGE Android.

Java SDK

Check to see if you have Java installed:

javac -version

If you already have Java 1.8.* installed you can skip to the next section, Android.

Install a version of java:

sudo apt-add-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer

If you prefer openJDK:

sudo apt-get install openjdk-8-jre


javac -version

Android SDK

Download the Stand-alone SDK Tools, or Android Studio:

Unpack and install the contents:

tar zxvf android-sdk-linux.tgz
mv android-sdk-linux ~
echo "export ANDROID_HOME=`echo $HOME`/android-sdk-linux" >> ~/.bashrc && source ~/.bashrc

Use the Android SDK Manager GUI to install the correct version of the android sdk to your system:


Check the build configuration for the version of android you will need. You will also need to install Android Support Repository, Android Support Library, Google Play services, and Google Repository using the Android SDK Manager.


Android requires that you sign your applications. You will need to create an identity to sign your MAGE Android build. If you don't plan on releasing your build of MAGE, use Debug Build instructions, otherwise use the Release Build instructions. If you aren't sure, follow the Debug Build instructions.

Debug Build

First, check to see if you have a ~/.android/debug.keystore. If the file does not exist, generate one using keytool:

keytool -genkey -v -keystore ~/.android/debug.keystore -storepass android -alias androiddebugkey -keypass android -dname "CN=Android Debug,O=Android,C=US" -validity 14000

When finished, ~/.android/debug.keystore should now exist on your system. Verify the information you entered looks correct:

keytool -list -keystore  ~/.android/debug.keystore

If prompted for a password, enter android.

Release Build

Only follow these instructions if you would like to release or distribute your build of MAGE. If you already have a ~/.android/release.keystore skip to the next section, Google Maps Android API. If you don't have a ~/.android/release.keystore (or production keystore you use to sign other Android applications), create a new keystore file using the keytool utility:

keytool -genkey -v -keystore ~/.android/release.keystore -alias androidreleasekey -validity 14000

When finished, ~/.android/release.keystore should now exist on your system. Verify the information you entered looks correct:

keytool -list -keystore  ~/.android/release.keystore

Google Maps Android API

MAGE Android uses Google Maps. Whether you build a debug or release version of the application, you will need to obtain a Google Maps API key to use Android Google's Maps.

First, go to Google's API Library with a valid Google account, and enable the Google Maps Android API in the API Manager -> APIs section. Next, in the Credentials section, Create Credentials -> API key -> Android key. Enter a key name, or accept the default. Add package name and fingerprint, enter mil.nga.giat.mage for the package name, and the SHA-1 certificate fingerprint from the keystore you made. You can get the SHA-1 hash from the debug.keystore (if this is a release build, use your release keystore instead) you made using the command line:

keytool -list -keystore ~/.android/debug.keystore

If prompted for a password, enter android. Finally, click Create in Google's developer console. Once created, you should be prompted with a hash that represents the Android Google Maps API key.

To link the MAGE application with this api key you have just made, you must edit the DEBUG_MAPS_API_KEY value in file and enter your Android Google Maps API key hash. Congratulations! You are all done configuring your very own debug build of MAGE Android.


The MAGE Android application (apk) is built using gradle. These instructions build a debug version of the application that is not for release.

Before you build the MAGE Android application, make sure to download, build and deploy the MAGE SDK dependency to your local maven repository first.

This command will create the Android package that you will install on the phone:

./gradlew clean
./gradlew assembleDebug
file ./mage/build/outputs/apk/mage-android-defaults-debug.apk


With a device connected to your machine, you can install the MAGE app with the following command:

./gradlew installDefaultsDebug


Run the tests on your device:

./gradlew connectedDefaultsDebugAndroidTest
