💣📡📱 ExitGame Bomb - Android Client App

This app is part of an ExitGame where payers have to deactivate a bomb by coding challenges. The client app can configure the bomb remotely.

The Bomb runs on an android device. It starts with a countdown before it explodes. It's not accessible for the players. Players have to deactivate the bomb with coding challenges. The deactivation commands are sent to an REST interface of the bomb app.

🚀 Start

The App runs on Android and Desktop. So you can run, test and develop it without an Android device or emulator. To start the app run the Gradle task:

Run Desktop: desktop > Tasks > other > run
Run Android: android > Tasks > other > run
Build Android: android > Tasks > build > build

You can also run the DesktopLauncher class direct and skip the gradle build - which can be faster. Then you have to set the Working directory of the Run Configuration to ${your-path}\bomb-app\android\assets.

After an android build, the apps apks are present in bomb-app\android\build\outputs\apk\debug and ...\release. You can install them with:
adb install -r "${full-path}\bomb-app\android\build\outputs\apk\debug\android-debug.apk"

Run Gradle tasks with at least Gradle 5.5 and ensure it runs with a Java 1.8 JDK. You can check this here:
IntelliJ > Settings > Build, Execution, Deployment > Build Tools > Gradle > Gradle JVM

💡 External Hardware

💡 The comb can be paired with external Hardware. It connects to a Phillips Hue bridge and controls lights. So lights switch to if the bomb gets activated and to if it gets disarmed. See HueService or yetanotherhueapi for details.

🔊 To bomb also plays audio files, so it may be a good idea to connect it with an external Bluetooth speaker.

⏰ The bomb can connect to an external Arduino hardware based 7-segment countdown timer.
This optional project is available here: Arduino-Countdown-Timer. See TimerService for interface details.

The settings screen allows you to change the bombs configuration.

🐞 Troubleshooting

Exception in thread "LWJGL Application" com.badlogic.gdx.utils.GdxRuntimeException: 
Couldn't load file: icons/icon_16.png

You forgot to to set the Working directory of the Run Configuration to ${your-path}\bomb-app\android\assets.

Could not resolve all files for configuration ':core:compileClasspath'.
   > Could not find io.github.tobsef:yetanotherhueapi:1.3.0.

You need the yetanotherhueapi maven dependency. For now it may be not present int the maven central. So check it out and manual install it with:
git clone https://github.com/TobseF/yetanotherhueapi.git
mvn install -DskipTests
