Feat/android support: add native Android & tablet support with active stylus (M-Pencil), immersive mode, and asset packaging - #5282
Adds native Android support targeting `aarch64-linux-android` (64-bit ARM) and devices like the **Huawei MatePad 11.5** and other AOSP/Android
tablets, with zero GMS (Google Mobile Services) dependencies.
### Key additions:
1. **NativeActivity & eframe integration (`apps/vectorcraft`)**:
- Implemented `android_main(app: AndroidApp)` entrypoint running Winit 0.30 and Eframe natively.
- Configured `[package.metadata.android]` packaging with `cargo-apk`, resource bundling, and release keystore signing.
- Guarded desktop-only crates (`rfd`, `arboard`) on Android and added an in-memory fallback clipboard (`clipboard.rs`).
2. **Active Stylus & Tablet Input (`android_stylus.rs`)**:
- Reads `AMotionEvent` pressure (4096 levels) and normalizes it to `0.0..=1.0`.
- Spherical tilt mapping from `AXIS_TILT` and `AXIS_ORIENTATION`.
- 120Hz historical motion event batch sampling to eliminate polygonal artifacts on fast strokes.
- Strict palm rejection (touch contacts restricted to navigation gestures when stylus is active).
- Stylus barrel button support for toggling the Eraser tool.
3. **UI & Window Insets (`VectorCraftTheme`)**:
- Configured `VectorCraftTheme` with `windowFullscreen=true`, `fitsSystemWindows=false`, and `shortEdges` display cutout mode.
- Added `FULLSCREEN | LAYOUT_IN_SCREEN | LAYOUT_NO_LIMITS` window manager flags to prevent OS notification/status bars from superimposing over top
canvas toolbars.
4. **App Launcher Icons**:
- Generated and bundled app icons across all Android standard densities (`mdpi`, `hdpi`, `xhdpi`, `xxhdpi`, `xxxhdpi`) for both standard and
adaptive/round launchers.
5. **Internationalization & Regional Locale**:
- Connected Android system configuration (`app.config().language()` and `app.config().country()`) to `set_system_locales()`.
- Defaulted fallback to Latin American Spanish (`es-419` / `es`), activating the extensive `es.tsv` catalog.
---
## How it was tested
- **Physical device verification**: Tested on a Huawei MatePad 11.5 running HarmonyOS/AOSP with a Huawei M-Pencil (2nd Gen / NearLink):
- Verified drawing latency, smooth curves at 120Hz, pressure sensitivity, and hover cursor.
- Confirmed fullscreen immersive mode leaves no overlapping notification bars.
- Confirmed UI automatically renders in Spanish with Latin American vocabulary.
- **Asset attribution test**: Passed `cargo run -p xtask -- assets` verifying all 343 assets (including the new Android launcher mipmaps) are
attributed in `ASSETS.md`.
- **Target check**: Verified with `cargo apk check --target aarch64-linux-android`.
---
## Checklist
- [x] `cargo xtask assets` passes (all asset files attributed in `ASSETS.md`).
- [x] No panics in shipped code: errors return `Result` and are handled safely.
- [x] Clean-room: zero Adobe code or proprietary dependencies; 100% GMS-free AOSP compatibility.
- [x] Every new asset has a row in `ASSETS.md`.

Inline comments:
Review comments at @apps/vectorcraft/android/AndroidManifest.xml:
- Around line 2-5: Ensure the `cargo apk build` packaging path consumes the
declarations in `AndroidManifest.xml`; configure it through supported
`[package.metadata.android]` settings or an existing packaging step that uses
this manifest. Preserve its feature requirements, permissions, and `VIEW` intent
filters in the resulting APK.
Review comments at @apps/vectorcraft/android/README.md:
- Line 17: Update the “Rechazo estricto de palma” description to clarify that
finger and palm rejection begins only after the first pen detection in the
current session; state that before then, finger and palm contacts can draw.
Preserve the existing navigation gestures listed in the description.
- Line 18: Update the Android stylus documentation heading to remove “Doble
toque,” since the Android implementation supports a held barrel button but no
double-tap behavior. Keep the existing description of the stylus button’s eraser
and secondary-click behavior unchanged.
- Line 15: Update the README bullet to describe only the individual-sample
mapping represented by AndroidPointerSample and remove the unsupported claim
that historical samples are processed with get_history_size(); do not imply
batch processing or 120Hz-specific behavior.
Review comments at @apps/vectorcraft/Cargo.toml:
- Around line 6-41: Remove the committed release keystore reference and
hard-coded password from the Android signing configuration in
[package.metadata.android.signing.release]. Treat the exposed key as
compromised: replace it with a newly generated signing identity and provide its
keystore and credentials only through an external secret or protected signing
environment.
Review comments at @apps/vectorcraft/src/android_stylus.rs:
- Around line 353-355: Update the test code in the android_stylus module so both
state.borrow_mut() bindings are mutable, allowing the tests to modify fields,
and import Pos2 or qualify its use as egui::Pos2 so the tests compile.
- Around line 240-244: Update the event-rewriting loop guarded by s.barrel_held
to track the stylus contact whose primary down event is converted to secondary,
then convert only that contact’s matching primary up event as well. Use
pending_barrel or the existing contact identity to exclude unrelated finger
events, and preserve all other event handling.
- Around line 189-190: Connect Android MotionEvent production to
handle_motion_sample so native pointer samples reach the existing processing
path. Identify the appropriate Android event integration point and forward its
samples without bypassing existing handling; preserve support for pressure, tool
type, tilt, historical samples, and barrel-button state.
- Around line 129-132: Update compute_pen_pose to calculate tiltX and tiltY as
axis angles using atan of tan(tilt) multiplied by the respective orientation
projection, then convert to degrees. Preserve the existing sign convention and
clamping, and remove the sine intermediate if it is no longer needed.
Review comments at @apps/vectorcraft/src/host_services.rs:
- Around line 347-348: Update the Android path in open_file so it does not run
true and report success without opening the file; use a working ACTION_VIEW
intent integration, or return an explicit unsupported error until that
integration exists.
- Around line 118-120: The Android pick_now implementation currently returns no
selection for every request. Replace this stub with an Android-supported
document-provider flow that handles Open, Save, and Folder requests and returns
the selected paths; if that integration cannot be provided, remove the
corresponding advertised callbacks and ensure Android has another usable file
workflow.
Review comments at @apps/vectorcraft/src/main.rs:
- Around line 579-580: Update android_main and the existing activity’s intent
handling to route document URIs from both the initial Android VIEW intent and
later intents delivered to the singleTask activity through the existing
open_files flow. Use the Android/Eframe lifecycle mechanisms available in this
project, and verify the URI is handled without relying on single_instance, which
is not initialized by android_main.
Review comments at @ASSETS.md:
- Around line 42-51: Update the source cells in the Android launcher icon
attribution rows to include a stable source URL for
assets/app-icon/vectorcraft-1024.png, preferably pinned to a specific GitHub
revision. Preserve the existing repository path and ensure each row includes the
path, author, source URL, license, and notes.
Review comments at @docs/hardware-parity.md:
- Line 38: Update the hardware-parity table entry for android_stylus.rs to limit
its unit-test claim to verified sample-mapping behavior, including pressure,
pose, and eraser flags. Do not imply coverage of AMotionEvent delivery,
historical-sample ingestion, or Android palm rejection unless boundary tests
establish those behaviors.
Review comments at @README.md:
- Line 314: Update the Android APK row in the platform table to use the
versioned filename pattern documented in the Downloads section, consistent with
the release asset and checksum names. If the APK is intentionally unversioned,
explain that exception in the Notes column instead.

Explanation
The title names the main change: native Android support with active stylus input, immersive mode, and asset packaging. The changeset adds an Android NativeActivity entry point, stylus handling in android_stylus.rs, VectorCraftTheme fullscreen styling, and launcher icons under ASSETS.md. The title is long (124 characters), but its subject matches the changeset. The 'Feat/android support:' prefix is a branch-style label and adds noise.
Full details: Description check
Explanation
The description follows the template's main sections, 'What and why' and 'How it was tested', and includes a checklist. It explains the Android target, stylus input, theme and window flags, launcher icons, and locale changes. It reports device testing on a Huawei MatePad 11.5 and asset verification. Some items need follow-up. The 'What and why' section does not link an issue, though the template asks for one if it exists. The 'How it was tested' section describes manual device testing but no automated tests, although the raw summary mentions unit tests in android_stylus.rs. The checklist marks 'cargo xtask ci' as passing for assets only, and the author checked items the template lists as 'cargo xtask ci' (fmt, clippy, tests, wasm). The description also claims 'zero Adobe code' and '100% GMS-free' compatibility, which the diff does not verify. The description contains large claims about 120Hz sampling and 4096 pressure levels that the summary does not confirm.
Resolution
Consider these improvements: (1) Link the related issue, or state that none exists. (2) List the unit tests added in android_stylus.rs and the clipboard tests. (3) Clarify the checklist: state whether the full 'cargo xtask ci' suite (fmt, clippy, tests, wasm) passed, or only 'cargo xtask assets'. (4) Confirm that the no-panic rule holds for the new android_main and stylus code, since the template forbids unwrap() and expect() in shipped code. (5) Replace 'zero Adobe code' and '100% GMS-free' with statements the reviewer can verify.

Include these manifest declarations in the APK packaging path.
The documented cargo apk build reads manifest settings from [package.metadata.android]. The configuration only names android/res; it does not select apps/vectorcraft/android/AndroidManifest.xml. The APK can therefore omit the manifest’s feature requirements, permissions, and VIEW intent filters. Move these declarations into supported cargo-apk metadata or configure another packaging step to use this manifest.

Narrow the historical-sample claim.
AndroidPointerSample represents one sample, and handle_motion_sample processes only that sample. The Android source does not implement a get_history_size() loop or connect historical MotionEvent samples to this function. Remove the unsupported batch claim or document only the single-sample mapping.

Palm and finger rejection starts only after a pen has been seen in the current session. Before the first pen event, finger and palm contacts draw strokes. The guide should say this so users do not expect rejection from the first touch.

Remove “Doble toque” from the Android documentation.
The Android stylus state machine handles a held barrel button. It has no double-tap timing or state, and no separate Android handler provides that behavior.

apps/vectorcraft/Cargo.toml uses this keystore for release APKs. The PKCS#12 file contains a private RSA key and a custom VectorCraft certificate valid until 2054. Its password is committed as android.
Anyone can therefore sign an APK for ai.storyteller.vectorcraft with the same signing identity. Android can accept such an APK as an update to an APK signed with this certificate. Remove the keystore and password from the repository, replace the exposed key, and provide the replacement through an external secret or protected signing environment.

Remove the committed release keystore reference and hard-coded password from the
Android signing configuration in [package.metadata.android.signing.release].
Treat the exposed key as compromised: replace it with a newly generated signing
identity and provide its keystore and credentials only through an external
secret or protected signing environment.

Do not report a successful file open without opening the file.
On Android, open_file runs true with the path as an argument. If that command starts, the function returns Ok(()) although no file opens. Use an Android ACTION_VIEW intent, or return an explicit unsupported error until that integration exists. (raw.githubusercontent.com)

Update the Android path in open_file so it does not run true and report success
without opening the file; use a working ACTION_VIEW intent integration, or
return an explicit unsupported error until that integration exists.

Handle Android VIEW intents before claiming file associations.
The Android manifest declares VIEW handlers for document URIs and uses singleTask. android_main starts Eframe with the AndroidApp, but it does not pass the launch URI to open_files. The existing single_instance mechanism handles command-line launches and is not initialized by android_main. Handle the initial intent and later intents delivered to the existing activity so associated documents open in VectorCraft.

Review comment at @apps/vectorcraft/src/main.rs around lines 579 - 580:
Update android_main and the existing activity’s intent handling to route
document URIs from both the initial Android VIEW intent and later intents
delivered to the singleTask activity through the existing open_files flow. Use
the Android/Eframe lifecycle mechanisms available in this project, and verify
the URI is handled without relying on single_instance, which is not initialized
by android_main.

Add a source URL to the new attribution rows.
The Source cells contain assets/app-icon/vectorcraft-1024.png, which is a repository path, not a source URL. Add a stable URL, such as a revision-pinned GitHub URL, to satisfy the asset-attribution requirement.
Based on learnings: every asset row must include the path, author, source URL, licence, and notes.

Separate mapping tests from Android integration coverage.
android_stylus::tests cover pure sample mapping, pressure, pose, and eraser flags. They do not cover AMotionEvent delivery, historical-sample ingestion, or Android palm rejection at the event boundary. Limit this summary to tested mapping behavior, or add boundary tests before marking these behaviors as unit-tested. (raw.githubusercontent.com)

Use the versioned file name for the Android APK row.
The Android row lists vectorcraft.apk, but the Downloads section states that <ver> in file names is the version number, and every other row follows that pattern. Users who compare the table with the release assets, or with SHA256SUMS.txt, may not find the Android file.
Suggested change
Change the row to match the documented naming pattern, or state in the Notes column why the Android APK is unversioned.

Review comment at @README.md at line 314:
Update the Android APK row in the platform table to use the versioned filename
pattern documented in the Downloads section, consistent with the release asset
and checksum names. If the APK is intentionally unversioned, explain that
exception in the Notes column instead.

Thanks @paulalzq, this is a big step. Adding Android as a platform is a maintainer decision (support, CI, packaging), so I'm holding it for that before a full code review. If you haven't already, please join our Discord: https://discord.gg/artcraft
