# # SamFonts <p align="center"> <b style="font-size: 3.5em;">SamFonts</b> <br><br> <img src="samfonts.png" alt="SamFonts App Screenshot" width="350"> </p> [](https://opensource.org/licenses/Apache-2.0) []() []() SamFonts is a powerful, ground-up rebuild utility designed for Samsung One UI devices. It allows users to dynamically generate, sign, and install custom `.ttf` and `.otf` font packages directly on-device without root, leveraging Shizuku. Featuring a beautiful, native-feeling OneUI 8.5 design language written entirely in Jetpack Compose, SamFonts handles the heavy lifting of Android's modern font management seamlessly. [📦 Download the Latest Release]([#](https://github.com/fahadalijaved/SamFonts/releases)) *<!-- Replace '#' with your actual GitHub release link -->* --- ## ✨ Features ### 🎨 Native OneUI 8.5 Visuals * **Fluid UI:** Built entirely in Jetpack Compose featuring a collapsing hero header that shrinks smoothly on scroll, matching native Samsung Settings. * **Seamless Navigation:** Animated pill-style segmented tab rows with spring physics, supporting horizontal swipe paging between *Installed*, *Available*, and *About* tabs. * **Modern Components:** Uses the signature OneUI card system (`20dp` rounded surfaces, hairline `0.5dp` dividers, and smart top/bottom corner rounding for grouped lists). * **True Previews:** Font preview rows render text using their **actual typefaces** via lifecycle-aware `AndroidView` caching, eliminating system font placeholders. * **Adaptive Theming:** Full, native light and dark mode support using dynamic token swapping. ### ✒️ Advanced Font Customization * **Any Custom Font:** Pick any `.ttf` or `.otf` file from your system storage, or drop them into `/sdcard/SamFonts/` for automatic scanning on app launch. * **Bold Variant Support:** Attach a separate bold typeface file to any regular font. SamFonts pairs them perfectly within the generated APK. * **Pre-Install Renaming:** A OneUI-style bottom sheet lets you sanitize and customize the exact font name that will display in your system settings. * **Smart Source Tagging:** Automatically tracks and tags fonts as `System` (ROM-baked), `Built-in` (Monotype/Samsung packages), or `SamFonts` (installed via this app). * **Applied Tracking:** The currently active font is pinned cleanly to an "Applied" section at the top of your list and persists across reboots. --- ## 🔧 Technical Architecture & Under-the-Hood ### Dynamic APK Generation Pipeline SamFonts completely bypasses the need for pre-built asset packages by compiling a real, compliant Android font package on-device at runtime: * **Binary Manifest Patching:** Implements an in-memory UTF-16 string pool patcher for `AndroidManifest.xml` to dynamically swap package names, display names, and increment version codes via AXML chunk walking. * **Resource Alteration:** Executes byte-level UTF-8 replacement within `resources.arsc` to re-bind the `@@app_name` string asset. * **4-Byte Alignment Optimization:** Features a custom manual ZIP builder. Because standard `ZipOutputStream` cannot guarantee exact byte alignment, our pipeline writes the archive byte-by-byte to ensure `resources.arsc` lands on a 4-byte-aligned file offset—strictly satisfying constraints required by Android 11+ (`targetSdk >= 30`). * **On-the-Fly V2 Signing:** Integrates `apksig` alongside BouncyCastle to generate a unique RSA-2048 keypair and self-signed certificate entirely in memory per install instance. * **Samsung Font XML Engine:** Emits a properly formatted `<font>/<sans>/<file>/<droidname>` configuration architecture parsed natively by Samsung's `FontManagerService`. ### Hardened Session-Based Installation * Bypasses standard `pm install` blocks by implementing the modern three-step Package Installer Session API (`install-create` → `install-write` → `install-commit`) via Shizuku. * Streams raw APK bytes directly over an IPC pipe into the installer session, guaranteeing no temporary files are exposed on public storage. --- ## ⚙️ Requirements & Compatibility * **Device:** Samsung Galaxy Device running **One UI 8.0 or higher** * **Android OS:** Android 14.0+ (API 34) * **Prerequisite:** [Shizuku](https://shizuku.rikka.app/) must be running and authorized with **UID 1000 (system_server/systemshell)** privileges. * **Permissions:** `READ_EXTERNAL_STORAGE` / `READ_MEDIA_*` (Required only for drop-folder local scanning). --- ## 🛠️ Built With * **UI Framework:** Jetpack Compose (Material 3 tailored to OneUI 8.5 tokens) * **Security & Cryptography:** BouncyCastle + `apksig` * **Inter-process Communication:** Shizuku API * **Asynchronous Execution:** Kotlin Coroutines & Flow --- ## 👥 Credits & Acknowledgments SamFonts wouldn't be possible without the foundational work, research, and contributions of: * **Gabriel2392** * **VikramAditya** * **Wr3ckless1** --- ## 📄 License ```text Copyright 2026 SamFonts Developers Licensed under the Apache License, Version 2.0 (the "License"); you may not use this file except in compliance with the License.
