#Android Runtime Binding
MoonBit bindings for selected Android runtime capabilities, built on AJNI. Version 0.1.1 provides Android system logging through android.util.Log with MoonBit 0.10.19.
#Requirements
- Android host initialized with AJNI before calling this package.
- MoonBit native target and Android NDK configured by the host application.
- MoonBit 0.10.19+97801ee1b (moon CLI 0.1.20261029).
#Use from this checkout
Resolve the published AJNI dependency from the repository root:
moon update
moon check --target nativeAdd the package import in the consuming moon.pkg:
import {
"Nanaloveyuki/android_runtimebinding/log",
}Call it after the AJNI host initializes, on its owner thread, from an error-raising function:
let logger = @log.Logger::new("Index")
logger.log(@log.Level::Info, "Index built")Logger::new binds a tag and the current AJNI session; reuse the logger for subsequent writes. Logger::log raises AJNI's RuntimeError if the JNI session is unavailable, belongs to another thread, or the Java call fails. Use Android logcat to view the message. Supported priorities are Verbose, Debug, Info, Warn, and Error.
#Run the Android example
Install Android SDK Platform 36, Build Tools 36.0.0, NDK 29.0.14206865, and CMake 3.22.1. Set ANDROID_HOME to the SDK and MOON_HOME to your MoonBit installation. Java 17 or newer is required.
From the repository root:
examples/android/gradlew -p examples/android :app:assembleDebug
python3 scripts/run-android-smoke.py --serial emulator-5554The example defaults to x86_64. For an ARM64 device, build with -PandroidAbi=arm64-v8a and pass its ADB serial to the smoke command. Use --adb /path/to/adb if ADB is not on PATH; WSL can use Windows adb.exe with the same option.
The smoke command installs the APK and launches it twice, checking five priorities, a Unicode message, and rejection before host initialization in logcat. The example requires no runtime permissions.
#Implementation
The Android adapter calls the public android.util.Log.println API through AJNI's checked JNI runtime. It requires a live AJNI session on its owner thread. This package does not initialize the Android host or manage UI, permissions, or application resources.
#Suitability
Use this package from MoonBit native code embedded in an Android application that integrates AJNI. The included application demonstrates host setup and logging; application UI, permissions, and other system capabilities remain the application's responsibility.
