# WebToApp
### Build Android APKs from web projects, directly on your phone.
**An on-device APK workshop that goes far beyond URL wrapping — it can fork and exec full server runtimes, ship a hardened anti-censorship network stack, sign bundles for Google Play, and run MV3 browser extensions, all without a PC or a remote build server.**

## What makes WebToApp different
Most "website to app" tools stop at wrapping a URL in a WebView. WebToApp is closer to a pocket-sized APK workshop, and the hard parts are exactly where it diverges:
- **It runs real server runtimes on-device.** Node.js, PHP, Python, Go, and WordPress are fork+exec'd as native binaries straight from app storage — like Termux, packaged into an installable APK. URL-wrapper tools cannot do this at all.
- **It ships a hardened, anti-censorship network stack.** DNS-over-HTTPS, TLS fingerprint spoofing (Chrome / Firefox / Safari JA3 templates) with a local MITM bridge, Encrypted Client Hello (ECH) on the GeckoView engine to encrypt the SNI, per-app proxies, and CORS bypass for locked-down SPAs.
- **The whole build is self-contained.** Binary AXML/ARSC patching, permission pruning, V1/V2/V3 signing, and Google Play-ready AAB export all happen inside the app via `apksig` — no remote build queue, no PC.
- **It stays extensible after shipping.** Add JS/CSS modules, Tampermonkey-style userscripts, or MV3 Chrome extensions (live-searched and installed from the Chrome Web Store) without rebuilding the host.
- **The host UI speaks 10 languages out of the box.** Chinese, English, Arabic (RTL), Portuguese, Spanish, French, German, Russian, Japanese, and Korean — switch anytime in Settings; new in-app copy is maintained for all ten.

## Full feature map
WebToApp has a large number of switches. The sections below group them by use case, kept collapsible so the top of the page stays scannable.
🌐 Browser engine & networking
- **Dual engine** — System WebView by default, or an optional GeckoView (Firefox) runtime downloaded on first use.
- **Kernel flavor disguise** — present as Chrome, Edge, Samsung Internet, Firefox, or Safari-style while keeping the real engine.
- **Desktop mode**, custom User-Agent, and JS/CSS injection at document-start / end / idle.
- **Popup handling** — same window, external browser, popup window, or block.
- **Proxies** — static HTTP/HTTPS/SOCKS5, PAC, authentication, bypass rules, and a local HTTP-to-SOCKS bridge.
- **DNS-over-HTTPS** — Cloudflare, Google, AdGuard, NextDNS, CleanBrowsing, Quad9, Mullvad, plus custom endpoints; strict or automatic modes.
- **Encrypted Client Hello (ECH)** — encrypt the SNI in the TLS handshake (GeckoView only; auto-wires DoH + GeckoView when toggled).
- **TLS fingerprint spoofing** — impersonate Chrome 131 / Firefox 133 / Safari 18 JA3 profiles (or custom ciphers), served through a local TLS-MITM bridge so the outgoing ClientHello matches a real browser.
- **CORS bypass** — on by default for static SPAs that call external APIs blocked by CORS; same-origin traffic is left alone, and CORS-only apps can use a lightweight `PrivateNetworkNativeBridgeAdapter` without the full Native Bridge surface.
- **Failover** — automatic fallback to mirror URLs when the primary target is unreachable.
- **PWA** offline cache strategies, custom error pages, per-app host overrides, and payment-scheme handlers.
- **Compatibility toggles** — blob download interception, scroll memory, image repair, clipboard / orientation / notification polyfills, private-network bridging, and Native Bridge capability gates.
- **Download location** — system Downloads, app-private storage, or a user-picked SAF folder, wired through the full packaging passthrough chain.
🛡️ Privacy, fingerprint defense & hardening
- **Browser fingerprint disguise across 50+ vectors** — User-Agent, WebGL, Canvas, AudioContext, ClientRects, timezone, language, memory, media devices, WebRTC, fonts, battery, permissions, performance, storage, notifications, CSS media, iframe propagation, and error-stack cleanup.
- **Hosts-rule ad blocker** with cosmetic MutationObserver filtering, **20 built-in community filter lists** (EasyList, uBlock Origin, AdGuard, AdAway, plus 8 language-specific lists), per-source enable/disable/delete, and custom subscription rules bundled into the APK.
- **Resource encryption** (PBKDF2 + AES-256-GCM) for packaged config, HTML, media, and BGM; optional custom encryption password stronger than package/certificate-derived keys.
- **Runtime hardening** when encryption is on — anti-debug, anti-Frida, DEX-tamper checks; threat response of log-only, silent exit, or randomized crash.
- **WebView/content isolation** for storage, WebRTC, Canvas, Audio, WebGL, fonts, headers, and IP surfaces.
- **Activation-code gating** — local verification, or your own HTTPS endpoint signed with EC P-256. See the [remote activation docs](.github/docs/remote-activation.md).
📦 Local server runtimes (fork + exec on-device)
- **Node.js** (18.20.x) runs in a dedicated `:nodejs` OS process via a native `node_launcher` wrapper loading `libnode.so`; supports custom native `.node` extensions.
- **PHP 8.4** from `pmmp/PHP-Binaries`, downloaded once on first use, with Composer 2.10.x and custom native extensions (`zend_extension`, `.so`).
- **Python 3.14** — Flask, Django, FastAPI via uvicorn, Tornado, the built-in HTTP server; pip dependencies resolved into `.pypackages`, custom native extensions supported; binary names are versioned so future bumps do not hard-code paths.
- **Go 1.26** — official Linux arm64 toolchain (`.tar.gz` from `dl.google.com`, USTC mirror for CN), on-device `go build` / `go mod` / `go run`, `vendor/` offline builds, static serving, and the native `go_exec_loader` wrapper; DNS and CA trust go through the same local JVM bridge used by PHP.
- **WordPress 7.x** over local PHP + SQLite (`sqlite-database-integration`), with theme and plugin import.
- **Linux Environment** screen manages toolchains and dependencies for Node, PHP, and Python.
- **Port Manager** coordinates runtime ports across generated apps via broadcast receivers.
- A **local DNS bridge proxy** (HTTP CONNECT in the Android JVM) gives runtimes working DNS resolution and outbound HTTP where the musl/packed binary can't reach the system resolver.
🧩 Extensions & automation
- **Built-in modules** — video download (YouTube / Bilibili / Douyin / Xiaohongshu extractors), video enhancer with YouTube cleanup (ad skip, max quality, background play, SponsorBlock), web analyzer, find-in-page, dark mode, privacy tools, content enhancer, element blocker, and YouTube launcher.
- **Userscripts** — Greasemonkey/Tampermonkey-style `.user.js` with a `GM_*` bridge (storage, requests, styles, menu commands) and promise-based `GM.*` APIs gated by script grants.
- **MV3 Chrome extension runtime** for manifest content scripts in isolated or main worlds, with `chrome.*` polyfills for runtime, storage, tabs, scripting, and declarative network-request parsing.
- **In-app Chrome Web Store search** — browse and install browser extensions by keyword (or paste a store URL / extension ID), with offline fallback to manual import.
- **Export codes** (`WTA1:` gzip + Base64) and QR sharing via ZXing.
- **AI Coding** skills to generate modules, userscripts, MV3 extensions, front-end apps, and local runtime projects, with automatic retry/backoff on 429/5xx and plan-mode exit that waits for user approval.
📱 App experience
- **Splash screens** — image or video, with skip behavior, trim ranges, and fixed orientation.
- **Background music** — playlists with synced LRC lyrics, lyric animations, custom font/color/stroke/shadow, and online music search.
- **Toolbar, status bar (light & dark), navigation, floating-window mode, and long-press menu styles.** Status bar color can follow theme, a custom color, full transparency, or **PAGE_TOP** (sample the page’s top pixels so the chrome matches the content).
- **Download location mode** — system Downloads, app-private directory, or a custom SAF folder picked by the user.
- **Announcement templates** for launch, interval, and no-network moments.
- **Host app language** — switch the entire builder UI among 10 languages (中文 / English / العربية / Português / Español / Français / Deutsch / Русский / 日本語 / 한국어); Arabic is full RTL.
- **Translation overlay** — 20 target languages via Google, MyMemory, LibreTranslate, Lingva, or Auto engines (in-page translate for the *content* of generated apps, separate from host UI language).
- **Print bridge** — intercept `window.print()` and blob/data-URL PDFs to the Android print framework / PDF export (with an onPageStarted re-inject fallback so late navigations stay hooked).
- **Notifications** — Web Notification polyfill, scheduled and persistent notifications with progress, URL-polling foreground service, deep links, boot auto-start, scheduled launch, and background-run service.
- **Per-app usage stats** with Vico charts and URL health monitoring.
🔧 APK / AAB export & signing
- **Custom package name**, `versionName`, `versionCode`, icon, label, architecture target, and export format.
- **Build-time permission injection** with unused permissions pruned from the template manifest.
- **One-tap AAB export** — auto-builds the APK on demand, converts it to a Play-ready signed AAB with `targetSdk` rewritten to the Play-required level (currently 35) and protobuf metadata generated locally; cancellable mid-build.
- **Keystore management** — create, import, export, delete, and certificate-fingerprint viewing; PKCS12/PFX/JKS/BKS import including Android Studio upload-key cases where store and key passwords differ.
- **Signature schemes** — V1, V2, V3 independently controlled, with auto-fallback for legacy certificates; custom V1 signer filename for `META-INF/.SF` / `.RSA`.
- **Performance options** — image compression, WebP conversion, code minification, lazy loading, DNS prefetch, and preload hints.
- **Full project and app-data backup/restore.**
🗂 File manager & project tooling
- **File manager** — a single screen to view, share, install, open, and clear build outputs (APK builds, AAB exports, app clones, build logs) and a user-files directory, with a read-only build-log viewer.
- **Website scraper** for offline packs — HTML, CSS, JS, images, fonts, `url()`, `srcset`, `@import`, path rewriting, same-domain limits, depth limits, and size limits; parallel streaming worker pool with main-thread progress callbacks.
- **Multi-Web layouts** — tabs, cards, feeds, drawers, per-site icons/theme colors/extraction selectors/refresh intervals, and shared JS/CSS.
- **Gallery apps** — categorized media, grid/list/timeline views, shuffle/single-loop, sorting, thumbnail bar, overlays, auto-next, and playback memory.
- **App Modifier** — shortcut disguise or real binary clone with manifest/resource patching and re-signing.
🔬 Specialized tools & research features
- **Forced-run**, **BlackTech**, **device disguise**, and **Icon Storm** are included for technical demonstration and must only be used with informed user consent.

## Module market
WebToApp has a GitHub-backed module market for community JS/CSS extension modules. The catalog is just files in this repository, so contributions use a normal pull-request flow.
```
modules/
├── registry.json # app-facing catalog
├── submissions.json # CI-generated PR / contributor metadata
├── README.md # contributor guide
└── / # each module
```
The app fetches both `registry.json` and `submissions.json` and only shows modules present in both, keeping the in-app catalog aligned with actually-merged PRs. The submissions file also records every contributor per module, so the catalog shows stacked avatars and a contributors leaderboard. Catalog files and module icons route through a global mirror first, with `raw.githubusercontent.com` and jsDelivr as automatic fallbacks, so the store loads fast everywhere (including mainland China).
- Users open **Extension Modules** and tap the storefront icon.
- Contributors add a folder under `modules/`, update `registry.json`, and open a PR.
- The default client cache is one hour, so merged modules propagate without an app update.
The high-level architecture lives here; the canonical submission rules, field schemas, reviewer checklist, and CI validation details live in [`modules/README.md`](modules/README.md).
The community market carries only JS/CSS extension modules. **Browser extensions (MV3)** are no longer a community catalog — instead the **Browser Extensions** tab searches the Chrome Web Store live: type a keyword, browse results, and install on demand through the existing CRX pipeline. Live search requires a network that can reach Google.
## Architecture
- The repository has **three Gradle modules**: `app` (the full builder and host), `shell` (the runtime host embedded into generated APKs), and `clone-host` (host code for app cloning — compiled to a `classes.jar`, converted to DEX via d8, and bundled as an asset for `AppCloner`).
- Runtime code is authored in `app` and synchronized into `shell`, so shared WebView/runtime behavior has one source of truth (`core/shell`, `core/webview`, `core/engine`, `core/extension`, `ui/shell`, etc.).
- The APK builder patches template APKs at the binary AXML/ARSC level, injects config/resources, prunes permissions, and signs with `apksig`. A separate encrypted build path (`EncryptedApkBuilder`) offers resource encryption, shelling, and integrity checks.
- The host pins `targetSdk = 28` deliberately — it is what lets generated apps fork+exec native runtimes (Node.js, PHP, Python, Go, WordPress) from app storage, a capability URL-wrapper tools lack. The AAB exporter separately rewrites `targetSdk` for Play Store distribution.
- Server runtimes and the optional GeckoView native runtime are downloaded on first use rather than bundled into the base APK.
- The configuration center is `WebApp` (`data/model/WebApp.kt`) and its `*Config` classes — the single source of truth for all feature settings, carried through a full packaging passthrough chain into the generated APK.
