Häufig Gestellte Fragen
Should I mention specific Android apps I've published?
Yes, absolutely. Published apps on Google Play provide tangible proof of your abilities. Include download counts, ratings, and any notable metrics — "Published 3 apps with 500K+ combined downloads and 4.5+ star ratings." If you've worked on well-known apps at previous companies, mention them by name if allowed by your NDA.
How important is Jetpack Compose experience for Android roles in 2026?
Very important. Jetpack Compose has become the standard for modern Android UI development. If you have Compose experience, highlight it prominently. If you're still learning, mention your progress and show awareness of the transition from XML layouts. Companies are actively migrating to Compose, so migration experience is also valuable.
Should I discuss my understanding of Android architecture patterns?
Briefly, yes. Mention your experience with MVVM, Clean Architecture, or MVI if relevant to the role. However, don't turn your cover letter into a technical lecture. A phrase like "implemented Clean Architecture to improve testability and reduce coupling" shows competence without excessive detail.
How do I address performance optimization experience?
Performance is critical for mobile apps. Mention specific optimizations: "Reduced app startup time by 40% through lazy initialization," "Decreased memory usage by 25% using image caching," or "Achieved 60fps scrolling through RecyclerView optimizations." Concrete metrics demonstrate you understand what matters for user experience.
