Android App Development: Developing mobile apps for Android devices using Java, Kotlin, or other programming languages. Android Studio is the preferred IDE for Android app development

Cross-Platform App Development: Using frameworks and tools like React Native and Flutter to create apps that can run on both iOS and Android platforms with a single codebase. This approach can save time and development costs.
