English | 简体中文

Android port of MNGA, an NGA (bbs.nga.cn) client. Built with Jetpack Compose, on top of the same Rust logic backend MNGA uses, linked in as liblogic.so over JNI.

Usage

• Download the latest APK from the Releases page:
  • app-release.apk — signed release build (recommended)
  • app-debug.apk — debug build (built by CI on every push)
• Install and sign in with your NGA account on first launch.
• mnga:// deep links are supported, e.g. mnga://forum/f/722 opens a forum directly; links copied to the clipboard are also detected and opened automatically when the app comes to the foreground.

Layout

• app/ — Compose UI, ported from the MNGA SwiftUI app.
• logic/ — Android library module wrapping liblogic.so plus the generated protobuf Java/Kotlin sources.
• rust/ — the Rust workspace liblogic.so is built from, vendored from MNGA. See rust/README.md.

Build

./gradlew assembleDebug

Output: app/build/outputs/apk/debug/app-debug.apk. JDK 17 required.

Gradle does not build the Rust side. liblogic.so is committed under logic/src/main/jniLibs/, so a plain Gradle build needs no NDK or Rust toolchain. After changing anything under rust/, rebuild and commit the libraries:

rust/build-jni-libs.sh      # liblogic.so for arm64-v8a, x86_64, x86
rust/gen-kotlin-protos.sh   # only when rust/protos/ changed

Both need protoc; the first also needs cargo-ndk and an Android NDK.

CI

• ci.yml builds the debug APK on every push/PR to main and uploads it as an artifact.
• rust.yml rebuilds liblogic.so for all three ABIs and runs the Rust unit tests, on changes under rust/ or on demand.

Attribution

MNGA ships without a LICENSE file and its README reserves all rights, so this port — including the Rust sources vendored under rust/ — is not redistributable without permission from its author. Vendored sled keeps its own MIT/Apache-2.0 license files in rust/logic/sled/.
