B4A (Basic4Android) IDE: Android App Development with BASIC

B4A (Basic4Android) is an integrated development environment (IDE) for creating Android apps using the BASIC programming language. It allows developers to create native Android apps using a simplified syntax and provides a range of tools and libraries to help streamline the development process. TTY (Teletypewriter) is a device used for text communication over long distances, primarily used by individuals with hearing or speech impairments. It allows users to type messages that are converted into electrical signals and transmitted to a receiving device. It is commonly used for telephone communication and can also be used with computers for text-based communication. However, it is not directly related to B4A or Android app development.
