What Makes Android Different
iOS is a narrow, predictable hardware range. Android is the opposite: screen sizes from compact phones to foldables and tablets, chipsets that vary enormously in performance, manufacturer layers that change how background work and notifications behave, and a user base spread across several OS versions at once.
That fragmentation is why Android apps that were only tested on a recent flagship fail in the field. Battery optimisation on one manufacturer silently kills your background sync; a mid-range device from three years ago drops frames in a list your team never scrolled far enough to see.
We build with that reality in mind and test on a matrix of real devices rather than an emulator alone, because that is where these problems appear.
How We Build
- Kotlin as the language, with coroutines and flows for asynchronous work
- Jetpack Compose for modern, maintainable interfaces
- Clean architecture with clear separation between UI, domain and data
- Room or a suitable local store for offline capability
- Retrofit and a well-defined API contract
- Dependency injection with Hilt
- Unit and instrumentation tests on the logic that matters
- Firebase Crashlytics, analytics and remote configuration
- CI pipelines producing signed builds automatically
- Play Console release management with staged rollouts
Google Play, Policy and Release
Publishing is not a formality. Google Play requires a privacy policy, a completed data-safety declaration, correct target API levels, and increasingly strict handling of permissions, background location and foreground services. Applications get rejected for declaration mismatches far more often than for code problems.
We handle store setup, listing assets, the data-safety form, review responses and staged rollouts, so a bad release reaches one per cent of users rather than all of them. You keep ownership of the developer account and the listing throughout.
Performance, Battery and Size
Users uninstall apps for three reasons more than any other: it is slow, it drains the battery, or it is too large to download on mobile data. All three are engineering decisions rather than accidents.
We profile startup time and frame rendering, move work off the main thread, batch and schedule background jobs through WorkManager so the system can be efficient with them, compress and lazily load images, and ship App Bundles so each device downloads only what it needs.
After Launch
Android ships a major version every year and Play enforces target API level deadlines, which means an unmaintained app eventually stops being installable by new users. Libraries deprecate, permissions tighten, and payment SDKs change their rules.
Our maintenance covers OS and API level updates, crash monitoring and fixes, performance work, Play policy compliance and small feature changes, with response times written into the agreement.
