Updated for compatibility with modern Android versions (API 34+) and enhanced with security hardening.

---

These updates ensure the launcher remains functional, secure, and performant on modern Android devices (Android 11 through Android 14+).

Pro Tip: On the very first install, if background transparency does not take effect immediately, simply type `restart` in the terminal and press enter.

• username [user] [device]: Instantly customize your terminal prompt. Changes both the username and device name and reloads the UI to apply.
• theme -preset [name]: Rapidly switch between high-quality pre-configured themes.
  • Available Presets: blue, red, green, pink, bw, cyberpunk.
  • Smart Suggestions: Applying a preset automatically colors the suggestion bar and shortcut buttons to match the aesthetic.
• bbman: The new BusyBox manager for installing and verifying Linux binaries.

• Built-in BusyBox Manager: Gain access to 300+ Linux commands (ls, grep, awk, top, etc.) via the new bbman -install command.
• Theme Preset Shortcut Buttons: Enhanced the theme -preset command to show interactive shortcut buttons for presets.
• Synchronized Theme UI: Applying a preset now automatically colors the shortcut buttons (suggestions) to match the overall theme.
• One-Tap Application: Shortcut buttons for theme presets execute immediately upon clicking.

To enable a full Linux environment, you can install BusyBox directly from the launcher:

1. Type bbman -install in the terminal.
2. The launcher will automatically detect your architecture, download the verified binary, and check its integrity.
3. Once finished, you can run any Linux command directly (e.g., ls, ping, vi).
4. To remove it at any time, use bbman -remove.

Security Note: Binaries are sourced from the trusted EXALAB repository and are verified against hardcoded SHA-256 hashes to ensure they have not been tampered with.

• Target SDK: Updated to API 34 (Android 14).
• Min SDK: API 21 (Android 5.0).
• AndroidX Migration: Fully migrated from legacy Support Libraries to AndroidX.
• Gradle & AGP: Updated to Gradle 8.2 and Android Gradle Plugin 8.2.0.
• Java Compatibility: Built with Java 17 support.

This project has been audited and hardened following the OWASP Mobile Application Security Verification Standard (MASVS).

• Scoped Storage Implementation: All application data has been moved from public external storage (/sdcard/t-ui/) to secure, app-private Scoped Storage (Context.getExternalFilesDir()). This prevents other applications from accessing your T-UI configuration and logs.
• Backup Protection: android:allowBackup is set to false to prevent sensitive data extraction via ADB backups (MASVS-STORAGE-1).
• Secure File Sharing: Uses FileProvider for secure, permission-based file sharing instead of vulnerable file:// URIs.

• Enforced TLS: android:usesCleartextTraffic is disabled globally. All network communications are forced over HTTPS (TLS 1.2+).
• Hardened Service Endpoints: Internal services (Weather API, Connectivity checks) have been upgraded to secure HTTPS endpoints (MASVS-NETWORK-1).

• Signature-Level Protection: Implemented a custom permission ohi.andre.consolelauncher.permission.RECEIVE_CMD with protectionLevel="signature". This ensures only apps signed with the same developer key can programmatically send commands to the launcher.
• Intent Security: All system-bound PendingIntents use the FLAG_IMMUTABLE flag to prevent intent redirection attacks (Android 12+ requirement).
• Receiver Security: All Broadcast Receivers are registered with appropriate export flags (RECEIVER_EXPORTED or RECEIVER_NOT_EXPORTED) to prevent unauthorized external triggers.

• Minification & Obfuscation: Release builds have R8/Proguard enabled (minifyEnabled true) to shrink resources and obfuscate code, making reverse engineering more difficult (MASVS-RESILIENCE-1).
• Foreground Service Security: Updated to comply with Android 14's strict foreground service types (specialUse, mediaPlayback).
