This pull request introduces several improvements and refactors across the codebase, with a focus on enhancing compatibility, improving language support, and making service management more robust. The most significant changes include switching all activities to inherit from AppCompatActivity for better compatibility, adding a language picker to the settings, and making notification lighting and automation services more reliable across different Android versions.

Activity Refactoring and Language Support

• All activities (MainActivity, SettingsActivity, FeatureSettingsActivity, AppUpdatesActivity, AppLockActivity, LinkPickerActivity) now extend AppCompatActivity instead of FragmentActivity or ComponentActivity, improving compatibility and support for modern Android features. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11]
• Added a language picker (LanguagePicker) to the settings screen, allowing users to select their preferred app language. Also, registered the AppLocalesMetadataHolderService in the manifest to support locale changes. [1] [2] [3]

Bluetooth Permissions and Manifest Updates

• Updated AndroidManifest.xml to include additional Bluetooth permissions with proper maxSdkVersion for compatibility with Android 12+, ensuring the app can interact with Bluetooth devices across a wider range of devices.

Notification Lighting and Automation Service Robustness

• Refactored NotificationLightingService to handle foreground service starts more reliably, using an intent extra (is_foreground_start) to control foreground state and fallback logic for different Android versions and OEM quirks. [1] [2] [3]
• Updated AutomationManager to use the same intent extra and added fallback logic for starting services on Android 14+ where background service restrictions are stricter.

Notification Listener Improvements

• Improved media session handling in NotificationListener by introducing a getMediaSessions helper that gracefully falls back when getActiveSessions is restricted, improving reliability for media controls and playback detection. [1] [2] [3]
• Enhanced notification lighting trigger logic to check for accessibility service status before starting the overlay service, ensuring proper behavior depending on user permissions. [1] [2]

These changes collectively enhance the app's stability, compatibility, and user experience, especially on newer Android versions and in multi-lingual environments.
