What great Android Developers look like
Great Android developers understand the realities of a fragmented ecosystem: thousands of devices, varying OS versions, battery optimisations and background limits. They write apps that start quickly, handle configuration changes and process death gracefully, and work smoothly on mid-range hardware. They keep up with Jetpack libraries and Google Play policy changes, and they test on real devices rather than only emulators.
Questions we ask in technical interviews
- How do you handle process death and state restoration?
- When would you use WorkManager versus a foreground service?
- How do you diagnose an ANR reported in Android vitals?
- How would you migrate a screen from XML views to Compose?
Typical projects for Android Developers
- New native Android apps
- Migrating legacy Java code to Kotlin and Compose
- Enterprise apps for managed devices and scanners
- Fixing crash rates and performance issues
- Bluetooth, NFC and hardware integrations
The first 30 days with a new Android developer
Every engagement starts with a short, structured onboarding so you see useful output early and can judge fit quickly. A typical first month looks like this:
-
Week 1 — Setup
Builds the app locally, runs it on emulators and real devices, reviews the architecture and ships a small fix through your review process.
-
Week 2 — First feature
Delivers a contained feature end to end, including Compose UI, view model, tests and a Play internal-testing build.
-
Week 3 — Quality pass
Reviews crash and ANR reports in Play Console or Crashlytics and proposes fixes for the most frequent issues.
-
Week 4 — Ownership
Takes a roadmap item from estimate to release and documents anything that slowed them down.
What to look for beyond the CV
Years of experience and a list of technologies say little about how someone works. In our screening and in your interviews, these are the signals that matter most:
- Tests on low-end devices and older Android versions, not only flagship phones
- Understands process death and restores state correctly
- Treats battery, background limits and permissions as product concerns
- Can read and modernise legacy Java and XML views without breaking them
- Explains trade-offs clearly in pull requests
Native Android or cross-platform?
If your app depends on deep Android integration — background services, Bluetooth, custom camera work, wearables or Android Auto — a native Kotlin developer is the right hire. If you need iOS and Android with a shared feature set and a small team, Flutter or React Native developers may deliver more for the same budget. We are happy to advise before you commit.
The Android-specific work to plan for
Android development has challenges iOS teams rarely face. Apps run on thousands of device models with different screen sizes, chipsets, manufacturer customisations and battery-saving rules. Background work, notifications and permissions behave differently between manufacturers, and each yearly Android release tightens rules around privacy and background execution. Google Play also sets a minimum target API level that apps must meet to keep publishing updates.
A strong Android developer plans for this: testing on a representative range of real devices, using WorkManager and modern APIs for background tasks, keeping the target SDK current and watching Android vitals in the Play Console for crashes and “app not responding” errors.
Typical Android tooling
Red flags when hiring Android developers
- Still writing new screens in Java and XML with no Compose experience, for a new project
- Unaware of Play Store target API requirements
- Tests only on one personal phone and the emulator
- Puts long-running work on the main thread or ignores lifecycle events
- Has not handled runtime permissions or notification changes in recent Android versions
Moving a legacy Android app forward
Many Android apps still contain Java code, XML layouts and older libraries. Rewriting everything at once is rarely necessary. A sensible developer converts new and frequently changed code to Kotlin first, introduces Jetpack Compose screen by screen alongside existing views, and upgrades libraries in small, tested steps. This keeps releases flowing while the codebase improves.

Questions to ask in an Android interview
- How would you test an app across devices from several manufacturers with limited time?
- How do you schedule a task that must run even if the user closes the app?
- What changes when the app targets the latest Android API level?
- How do you keep a Compose screen fast with a long, frequently updating list?
Good answers mention specific tools and trade-offs rather than general statements.
Play Store accounts and ownership
Always keep the Google Play developer account, signing keys and app listing under your company’s ownership, and give developers access through Play Console user permissions rather than shared logins. This keeps releases under your control if team members change.
Ways to engage
