As you grow as an Android developer, small habits make a huge difference in code quality, scalability, and maintainability. 1️⃣ Don’t Repeat Yourself (DRY) Always look for duplication. Extract reusable logic into utility classes or helper functions to keep your code clean and maintainable. 2️⃣ Prefer Built-in Extension Functions Before writing custom logic, check what Kotlin already offers. Extension functions often already solve your problem in a clean and idiomatic way. 3️⃣ Always Watch for Memory Leaks Be careful with Context, listeners, and long-living references. A single leak can silently destroy app performance over time. 4️⃣ Invest Time in Good Architecture Whether it’s MVVM, Clean Architecture, or MVI, structure matters. A good architecture saves you from technical debt later. 5️⃣ Use Structured Concurrency Leverage Kotlin Coroutines properly. Keep lifecycle-aware scopes and avoid leaking jobs or unmanaged background work. You build a great app by writing a great code.
