Android app development refers to the process of creating applications for devices running on the Android operating system. With the widespread usage of smartphones and tablets, Android app development has become a lucrative field for developers and businesses alike. Developing an Android app involves several key steps. It starts with conceptualizing the app idea and defining its purpose and functionality. Then, the app's design and user interface are created, considering the principles of usability and visual appeal. The next step is coding, where developers use programming languages such as Java or Kotlin to build the app's logic and functionality.
