A Mobile Application Framework is a software platform that provides developers with tools and libraries to create mobile applications. It simplifies the development process by offering pre-built components, which can save time and effort. Frameworks can support various operating systems, such as iOS and Android, allowing developers to write code that works across multiple devices. These frameworks often include features like user interface design, data management, and access to device hardware, such as cameras and GPS. Popular examples of mobile application frameworks include React Native, Flutter, and Xamarin, each offering unique advantages for building high-quality mobile apps efficiently.
