Add native Android app scaffold (M0): whisper.cpp engine via JNI
- android/: Gradle/Kotlin project (AGP 9.4, Compose, NDK 27.1), monorepo subdir as planned; whisper.cpp v1.9.3 vendored via pinned fetch script - core/whisper: JNI wrapper (beam size, threads, language) + WhisperEngine Kotlin API mirroring the desktop engine contract - app (M0 scope): in-app GGML model download from Hugging Face, engine load, WAV picker with resampling, on-device transcription, share sheet - build validated: assembleDebug OK, libwhisper_jni.so + ggml packaged

# MeetRec for Android
|
||||||
|
|
||||||
|
Native Android app with the same functionality as the desktop meetrec:
|
||||||
|
record meetings and transcribe them on-device with Whisper. Nothing leaves
|
||||||
|
the phone — no cloud, no telemetry.
|
||||||
|
|
||||||
|
Status: **M0 (engine proof)** — the app can download a GGML model, load it
|
||||||
|
via JNI (whisper.cpp, CPU/NEON) and transcribe a picked WAV file. Recording,
|
||||||
|
live transcript, and output files arrive in later milestones (see the
|
||||||
|
milestone plan in the project docs).
|
||||||
|
|
||||||
|
## Requirements
|
||||||
|
|
||||||
|
- Android Studio (or: SDK Platform 36, Build Tools 36, NDK 27.1, CMake 3.22.1)
|
||||||
|
- JDK 17+
|
||||||
|
- Device running Android 10+ (developed against a Fairphone 6 / Snapdragon
|
||||||
|
7s Gen 3, Android 15+)
|
||||||
|
|
||||||
|
## Build
|
||||||
|
|
||||||
|
```sh
|
||||||
|
cd android
|
||||||
|
./tools/fetch-whisper.sh # vendors whisper.cpp v1.9.3 into third_party/
|
||||||
|
./gradlew :app:assembleDebug # or open the android/ folder in Android Studio
|
||||||
|
adb install -r app/build/outputs/apk/debug/app-debug.apk
|
||||||
|
```
|
||||||
|
|
||||||
|
`third_party/whisper.cpp` is gitignored — the fetch script pins the exact
|
||||||
|
release tag so the JNI layer never breaks on upstream churn.
|
||||||
|
|
||||||
|
## Test on device (M0)
|
||||||
|
|
||||||
|
1. Launch **MeetRec**, pick a model (`tiny` is fine for a first test) and tap
|
||||||
|
**Download** (model comes from Hugging Face; tiny is ~75 MB).
|
||||||
|
2. Tap **Load engine**.
|
||||||
|
3. Tap **Pick WAV file** and choose a 16 kHz mono WAV for best results
|
||||||
|
(other PCM WAVs are resampled automatically).
|
||||||
|
4. Tap **Transcribe** — segments with timestamps appear; share via the
|
||||||
|
share sheet.
|
||||||
|
|
||||||
|
Expect roughly realtime transcription with `tiny`/`base` on the
|
||||||
|
Fairphone 6's CPU; `small` is noticeably slower — use it for final passes
|
||||||
|
only (the live/final split comes with the recorder milestones).
|
||||||
|
|
||||||
|
## Performance notes
|
||||||
|
|
||||||
|
- The engine runs on CPU via NEON, using up to 4 threads.
|
||||||
|
- GPU/NPU acceleration (e.g. Snapdragon NPU via the QNN backend) is a
|
||||||
|
stretch goal, not wired up yet.
|
||||||
|
|
||||||
|
## Module layout
|
||||||
|
|
||||||
|
```
|
||||||
|
app/ Compose UI (model download, WAV picker, transcript view)
|
||||||
|
core/whisper/ whisper.cpp JNI wrapper: CMake build + LibWhisper.kt +
|
||||||
|
WhisperEngine.kt (the on-device transcription API)
|
||||||
|
tools/ fetch-whisper.sh — vendor the pinned whisper.cpp release
|
||||||
|
```
|
||||||
|
|
||||||
|
Models live in the app's private storage (`filesDir/models`), shared files
|
||||||
|
with the desktop app's `~/.cache/meetrec/whisper-cpp` naming
|
||||||
|
(ggml-tiny.bin … ggml-large-v3.bin).

# gradlew start up script for POSIX generated by Gradle.
|
||||||
|
#
|
||||||
|
# Important for running:
|
||||||
|
#
|
||||||
|
# (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
|
||||||
|
# noncompliant, but you have some other compliant shell such as ksh or
|
||||||
|
# bash, then to run this script, type that shell name before the whole
|
||||||
|
# command line, like:
|
||||||
|
#
|
||||||
|
# ksh gradlew
|
||||||
|
#
|
||||||
|
# Busybox and similar reduced shells will NOT work, because this script
|
||||||
|
# requires all of these POSIX shell features:
|
||||||
|
# * functions;
|
||||||
|
# * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
|
||||||
|
# «${var#prefix}», «${var%suffix}», and «$( cmd )»;
|
||||||
|
# * compound commands having a testable exit status, especially «case»;
|
||||||
|
# * various built-in commands including «command», «set», and «ulimit».
|
||||||
|
#
|
||||||
|
# Important for patching:
|
||||||
|
#
|
||||||
|
# (2) This script targets any POSIX shell, so it avoids extensions provided
|
||||||
|
# by Bash, Ksh, etc; in particular arrays are avoided.
|
||||||
|
#
|
||||||
|
# The "traditional" practice of packing multiple parameters into a
|
||||||
|
# space-separated string is a well documented source of bugs and security
|
||||||
|
# problems, so this is (mostly) avoided, by progressively accumulating
|
||||||
|
# options in "$@", and eventually passing that to Java.
|
||||||
|
#
|
||||||
|
# Where the inherited environment variables (DEFAULT_JVM_OPTS, JAVA_OPTS,
|
||||||
|
# and GRADLE_OPTS) rely on word-splitting, this is performed explicitly;
|
||||||
|
# see the in-line comments for details.
|
||||||
|
#
|
||||||
|
# There are tweaks for specific operating systems such as AIX, CygWin,
|
||||||
|
# Darwin, MinGW, and NonStop.
|
||||||
|
#
|
||||||
|
# (3) This script is generated from the Groovy template
