What's new

CodeC IDE v1.3.18 — write and run C, Python, JavaScript and HTML on
your phone; C works offline with no setup.

The AI assistant — the whole line (Phases 84–96 / AI Levels 7–12). CodeC
now carries an optional, read-first AI assistant: open it from the ✨ rail
slot or the floating ✨ button. It runs on your own provider key (Google
Gemini by default; NVIDIA Build is a manual, internal-testing selection) —
there is no CodeC server and no shared key.

• Your key, your bill, your provider. The key is stored encrypted
  (Android Keystore AES-256-GCM) under no_backup/ai/ and never rides a
  backup; nothing leaves the phone until you tap Send on a preview that
  shows exactly what will be sent.

• Agent tools, and what they may see. list_files, search_project,
  read_file, read_files (up to 8 files per batch), plus the
  readable-structure results find_files, outline_file and
  read_run_output. search_project takes list_files' own scoping keys
  (max, path, ext) and can only narrow the walk's admitted list.
  Secret-like paths (.env, .npmrc, private keys), symlink escapes and
  build output are refused before they can reach a request.

• No write tool and no exec tool, by design. Edits arrive as a
  <<<CODEC_EDIT>>> proposal rendered as a diff you review; only your
  Apply writes (through AiEditApplier). A run request reaches CodeC's
  normal RUN ▶ pipeline only after you tap Run on the approval card —
  Skip runs nothing.

• Markdown answers. Headings, lists, tables and fenced code blocks, with
  a copy-only Copy per block; https links open only behind a confirm
  dialog that shows the full URL.

• The nine agent controls (AI panel): read window, working-set depth,
  task memory, answer detail, activity display, backup-provider offer, budget
  offer, reviewer — and request inspection, which is always on. Each control
  tunes inside a cap; none can grant a permission.

• Caps that no control can raise: 12 model turns, 24 tool calls, 2 runs,
  24 000-char reads, 8 000-char results, 8 batched reads, 3 identical
  repeats before the loop stops.

• History drawer and first-run agreement. Pinned/Recents rows, pin/unpin,
  a New-chat pill with one confirm, and a one-card welcome whose four bullets
  end in a pinned I understand — start.

• Six bug fixes and three first-run shape fixes from the device rounds —
  a settled conversation can no longer be filed under the wrong project or
  the wrong chat row, the drawer's New-chat pill keeps its confirm, ☰ can
  never go dead, the current row is marked, the Explain last error route
  redacts exactly like the read_run_output tool, and the agreement button,
  the first-run sheet height and the instant history row all behave on a
  small phone.

CodeC IDE v1.3.17

CodeC IDE v1.3.17

versionCode: 21
tag: app-v1.3.17
published: 2026-09-11

What's new

CodeC IDE v1.3.17 — write and run C, Python, JavaScript and HTML on
your phone; C works offline with no setup.

• First app release on the app-v* channel (see docs/JOURNEY.md for the full story).

Which APK should I install?

• Almost everyone: CodeC-IDE-1.3.17-universal.apk. It runs on
  every device CodeC supports (64-bit ARM phones, x86_64 emulators, and
  32-bit ARM phones).
• The per-ABI files (-arm64-v8a, -armeabi-v7a, -x86_64) are the same
  app minus the parts your device cannot use. Pick them when you know your
  device's ABI (Settings → About in the app shows it); when in doubt,
  take universal.
• 32-bit ARM (armeabi-v7a / older x86) devices: the built-in C compiler
  is not bundled for your ABI — C works through the downloadable Clang
  module (Packages tab) or the Termux fallback. Everything else in the app
  is the same.

Upgrading / downgrading

• Install the APK over the existing app — Android updates it in place and
  keeps your projects as long as the signing key is the same.
• The first release-signed build does not share a key with the old
  debug-signed CI builds: switching from a debug build to this release is a
  fresh install. Export your projects first (Files → project → Export
  ZIP, or Files → ⋮ → Export all projects) and import them back afterwards.
• The app's own Check for updates (Settings → About) never installs an
  older release over a newer one and says why.

Checksums

Verify before sideloading (sha256sum <file>), or let the in-app updater
check for you — it refuses to install anything whose checksum does not
match these lines, and refuses to install at all when none are published:

sha256: 7a2a204c901a8d9d240a08fdb4f0c19fd22ef952b494ab4fda3b72406144d0ce CodeC-IDE-1.3.17-universal.apk

What still bites (known issues)

• Opening a huge folder from the file picker can be slow on low-RAM phones;
  if it hangs, back out and open a smaller subfolder.
• Device-to-device restore and cloud backup carry your projects only —
  the toolchain, packages, and your GitHub sign-in do not travel; a fresh
  install downloads the userland again and asks you to sign in again (that
  is deliberate: the backup never carries your token).
• Everything user-visible that has bitten someone and what to do about it:
  TROUBLESHOOTING.md; beta notes: BETA.md.

Feedback

In the app: Settings → Feedback & Support (WhatsApp chat with the
developer, email, or a GitHub issue — nothing is sent unless you send it).
Rating and exit-survey answers ride the same report.

Privacy

CodeC runs entirely on your device. No analytics, no ads, no account, no
crash upload. The only network requests it makes are the ones you start:
the bootstrap/package downloads you approve, git against the repository you
configured, and this update check when you tap it. Details:
DATA_AND_PRIVACY.md.

CodeC userland bootstrap — Phase 3 development channel

CodeC userland bootstrap — Phase 3 (development channel)

Development release for CodeC IDE Phase 3 (package management).
The CodeC repository publishes signed InRelease and Release.gpg
metadata. The client pins the CodeC-only public keyring with
signed-by=, verifies with gpgv before apt, and apt verifies
the same Release/index/package hash chain independently.

Built from the pinned official termux-packages revision through
the CodeC overlay (com.codeci.ide, prefix
/data/data/com.codeci.ide/files/usr). No official com.termux
packages or repositories are used or referenced.

Contents

Bootstrap roots: busybox, bash, apt, dpkg, termux-exec
plus the full source-built dependency closure (never
build-package.sh -I).

Each archive contains the contents of the CodeC prefix
(root-level bin/, lib/, etc/, var/) and is extracted
into /data/data/com.codeci.ide/files/usr by the CodeC app
automatically. Do not extract by hand.

• Real CodeC-built apt, apt-get, dpkg + seeded dpkg status database
• libtermux-exec-ld-preload.so (shebang script execution via LD_PRELOAD)
• libandroid-support.so and all runtime shared libraries
• etc/apt/sources.list pointing at the CodeC development channel only
• CodeC v3 public keyring at etc/apt/keyrings/codec-archive-keyring-v1.gpg
  (byte-matched to the committed public key; no private material)

Source build: run 33598824226 of "CodeC package repository".

Rollback

• App side: userland-v1 remains published and is used automatically
  when this release is removed or unreachable
  (see docs/PHASE3_STATUS.md).
• Repository side: re-publish the previous Pages manifest by
  dispatching "CodeC package repository" with publish=true and the
  previous successful run ID.
