2. Subscription services.
3. Advertising and rewarded ads.
4. Enterprise apps and custom development.
5. Integration with Google Play’s new features and payment options keeps monetization flexible.

4. Strong Developer Support & Tools

1. Google continuously improves Android Studio, Jetpack libraries, and Kotlin, making development faster and more efficient.
2. New tools and APIs lower entry barriers and enhance app quality, which translates to better user retention and profitability.

5. Growing Demand for Mobile Apps

1. Businesses are increasingly shifting to mobile-first strategies.
2. Demand for apps in sectors like e-commerce, finance, health, education, entertainment, and productivity continues to rise.
