Building CellGuard

Toolchain

Component	Version
Gradle (wrapper)	8.9
Android Gradle Plugin	8.5.2
Kotlin	1.9.23
Compose compiler	1.5.11
JDK	21
compileSdk / targetSdk	35
minSdk	33
Build tools	35.0.0

These versions are mutually compatible: AGP 8.5.2 requires Gradle 8.7+ and JDK 17+ (JDK 21 is fine), and Kotlin 1.9.23 pins the Compose compiler extension to 1.5.11.

Prerequisites

JDK 21 installed at /usr/lib/jvm/java-21-openjdk-arm64
Android SDK at /home/snake/Android/Sdk with:
- platforms/android-35
- build-tools/35.0.0
Network access for the first build (downloads AndroidX, Compose BOM 2024.06.00, and libsu 5.2.2 from Google, Maven Central, and JitPack).

Build command (debug APK)

export JAVA_HOME=/usr/lib/jvm/java-21-openjdk-arm64
export ANDROID_HOME=/home/snake/Android/Sdk
cd /home/snake/CellGuard-app && ./gradlew :app:assembleDebug

Output

The debug APK is written to:

/home/snake/CellGuard-app/app/build/outputs/apk/debug/app-debug.apk

For a release (unsigned) build, run ./gradlew :app:assembleRelease; the artifact lands in app/build/outputs/apk/release/.
