Android App Feature Enhancement

I need to modify my existing Android app by adding a new feature: a floating window to control the dice number. Ideal skills and experience: - Experience in Android app development - Proficiency in creating and integrating floating window features - Strong understanding of app modification and feature addition - UI/UX design skills would be a plus, to ensure the new feature is user-friendly Please ensure the new feature is seamlessly integrated and does not disrupt the current functionality of the app. Looking forward to your bids!
