Summary of Changes

Hello @simona-anomis, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on improving the overall accessibility of the application by adding and refining content descriptions for key UI elements. The changes primarily target the camera capture functionality and various components within the home screen, ensuring a more informative experience for users relying on accessibility services.

Highlights

• Camera Capture Button Accessibility: I've enhanced the accessibility of the camera capture button by implementing dynamic content descriptions. The description now changes based on whether the button is enabled ('Capture image') or disabled ('Image capture disabled. Make sure your face is clearly visible in the frame.'), providing clearer context for users with accessibility needs.
• Home Screen Content Descriptions: I've improved the accessibility of elements on the home screen. Specifically, the 'VideoPlayerRotatedCard' now has a more descriptive content description ('A video showcasing the creation of an Android bot.'), and the 'DancingBot' image, which previously lacked a description, now clearly states 'A dancing Android bot.'.
• New String Resources: To support the accessibility improvements, I've added several new string resources. These include specific content descriptions for the enabled and disabled states of the camera capture button, as well as descriptions for the video card and dancing bot on the home screen.
