At the same time, people's needs are growing, which requires more and more developers to participate in application development and provide users with more diversified and convenient applications.App development is a comprehensive and technically demanding job, which requires developers to have a solid programming foundation and good design capabilities. Based on different operating systems, app development needs to master the corresponding programming language and development tools, such as the Android system, the use of Java or Kotlin programming language and Android Studio integrated development environment.The process of app development mainly includes: requirements analysis, interface design, function implementation, testing and release.
