DSH Mobile — Run the DeepSeek Harness agent natively on Android (no root, no Termux)

[Soodok]

Hi all! Sharing a community port I have been working on:

DSH Mobile — https://github.com/Soodok/Deepseek-Harness-Local-Android

It packages the full DeepSeek Harness agent stack into a 70MB APK:

• Self-built bionic runtime: node/bash/rg/pnpm/curl collected from the Termux package ecosystem with ELF closure verification — runs fully offline, no Termux app, no root
• Blazing fast first launch: cold start to engine-ready in under 10 seconds on a mid-range phone (~15s on tablets) — most Termux-based alternatives take minutes
• Extension Center: 19 on-device toolchains (Python, Go, Rust, Clang, OpenJDK, Git, Ruby, ...) installed directly from China-mirror Termux repos, with dependency-closure resolution and SHA-256 verification. The agent can also self-install tools through a local bridge
• System capability bridge: task-completion notifications, accessibility-based screen reading and tapping (scr dump / scr tap-text), name-based process management (psx/killx)
• Three-tier permissions: sandboxed (default) / Shizuku (adb-level via shz) / Root (with double confirmation, automatic dsh-home backup, and a su gate so the agent can not escalate outside Root mode)
• Self-healing: crash-signature based rollback and safe-mode pipeline, config surface only

A few hard-won notes from porting (full write-up coming soon):

1. TUNA mirror WAF silently 403s non-standard user agents — identify as APT/... instead
2. GNU tar longname bodies are NUL-padded; if your hand-rolled tar parser keeps the NUL, file creation explodes with "Invalid file path"
3. Android PathParser rejects SVG arc commands with compact flags ("0 01.292") — normalize flags before feeding Simple Icons paths to VectorDrawable
4. "su -c exec node" spawns su as the tracked child; killing the shell leaves the root node orphaned and still bound to your port — kill the process group

v1.2.23 is live under Releases (signed APK, arm64-v8a). Issues and ROM-compatibility reports are very welcome!
