AI2TH/Android Infrastructure

Linux on Android,
no root required.

Three apps that embed QEMU + Alpine Linux directly in the APK. Run Docker, Asterisk PBX, or a bare shell on any arm64 Android device.

alpine@android:~ 
$ uname -a
Linux alpine 6.1.0 #1 SMP PREEMPT arm64 GNU/Linux

$ docker run hello-world

Projects

Three apps. Same architecture. Different superpowers.

Linxr

Linxr

Alpine Linux Shell

A full Alpine Linux environment running inside QEMU on Android. Get a real bash shell, SSH access, persistent storage — on any arm64 phone with zero root.

  • OpenSSH server — connect from any SSH client
  • Built-in terminal with auto-reconnect
  • Persistent QCOW2 overlay across reboots
  • Full outbound internet via SLIRP networking
View details → GitHub APK
Pockr

Pockr

Merged into Linxr

Standalone Pockr app is deprecated. All Docker container management capabilities, container dashboards, and log streaming have been natively merged into Linxr under the Containers tab.

  • Pull & run any Docker image
  • Real-time container logs
  • Terminal into the Alpine VM host
  • Configurable vCPU + RAM (1–4 cores, 512 MB–4 GB)
View details → GitHub APK
Zyvr

Zyvr

Asterisk PBX on Android

Zero-carrier Your Voice Router. A full Asterisk 20 PBX running on your phone. Manage SIP extensions, monitor live calls, and route calls — carrier-independent.

  • Asterisk 20 with PJSIP driver
  • SIP extension management (create, delete, list)
  • Live call monitor + hangup
  • WebRTC/SIP.js support via WSS on 8089

How it works

Every app uses the same layered stack — QEMU gives the Linux VM, Alpine gives the environment, the app gives the UI.

Flutter UI (Dart)
Native Android UI — tabs, logs, terminal, settings
↓
Kotlin VmManager
Launches libqemu.so via JNI, manages ForegroundService lifecycle
↓
QEMU (libqemu.so)
Compiled as .so shipped inside the APK. Runs as a normal app process — no root.
↓
Alpine Linux VM
Boots from a bundled QCOW2 asset. SLIRP networking, persistent overlay, OpenRC init.
↓
Your workload
Docker daemon · Asterisk PBX · bash shell — whatever runs on Linux
