I need an experienced Android developer to build a utility app that allows users to connect a Bluetooth headset to another Bluetooth speaker seamlessly. The primary functionality should ensure smooth and reliable connectivity between these devices. Please focus on creating a user-friendly interface and robust backend to manage Bluetooth connections effectively. While I do not have a specific design or wireframe yet, I am open to your suggestions and expertise in UI/UX development to make the app intuitive and visually appealing. Deliverables should include the complete Android app with source code, thorough testing for compatibility, and setup instructions. If you have experience with Bluetooth APIs and Android development, I would love to hear from you!
