Core Mindsets for Android Developers

1. Be User-Centric

Always think about the end-user experience. Design for multiple screen sizes, performance on low-end devices, and battery life.

2. Adapt to the Ecosystem

The Android ecosystem is fragmented (devices, OS versions). Write robust, backward-compatible code and test thoroughly.

3. Prioritize Performance

Mobile users are impatient. Focus on app startup time, smooth UI, efficient background processing, and memory management.

4. Be a Lifelong Learner

Google constantly releases new APIs, libraries (Jetpack), and best practices. Always stay updated to avoid falling behind.
