I built an Android miner that cares more about your phone than your hashrate

I built AndroMiner, an open-source Android app that runs XMRig on your phone's CPU.

GitHub: https://github.com/Stawa/AndroMiner

What it does

Set up a coin, wallet, worker and pool (plain TCP or TLS)
Pick a CPU profile, or set threads, priority and core affinity yourself
Shows live hashrate, accepted/rejected shares and raw miner output
Stops mining when battery temperature hits your limit, Android reports severe thermal throttling, or required sensor readings go missing
Session timer that Android enforces even when the app is in the background
Local session history with JSON export
Pool connection test that checks DNS/TCP/TLS without sending your wallet

Stack

Vue 3 + TypeScript + Vite + Tailwind for the UI
Capacitor 8 to bridge into native Android code
XMRig compiled from source for arm64-v8a with the Android NDK

The UI is a web app, but mining and device monitoring run natively. That's why the timer and the protection checks keep working when the UI is closed.

Three APKs

tls: bundled miner with TLS support (most people want this one)
notls: bundled miner, plain TCP pools only
download: no bundled miner. It asks before downloading one and verifies the SHA-256 hash against the value built into the APK

Every release ships with a SHA256SUMS file.

Requirements

Android 7.0+
ARM64 device
Notifications enabled (each run shows an ongoing notification with a Stop button)

Being honest

Phone mining won't make you money. It heats up your phone and wears down the battery. Use a spare device and watch it while it runs. The app doesn't estimate earnings, on purpose.

I built this to see how far a Capacitor app can go with a native process underneath. It turned out to be a good test case.
