Amazon Fire TV アプリ開発サービス

• What Fire TV app development covers

  Fire TV work runs from a first build to keeping a published app healthy. I take the full scope: the interface, video playback, catalog browsing, sign-in, and Amazon in-app purchasing when the app charges. You can hand over a defined Fire TV project or bring me in to ship one that has stalled. Everything is billed at a flat remote day rate, with no agency markup.

• Fire TV is not an Android app any more

  This is the most expensive misunderstanding on the platform, so it is worth being blunt. The old Fire OS was built on Android, and most guides still tell you a Fire TV app is a Kotlin app with the Android TV libraries. On Amazon’s recent Vega devices that is no longer true: Vega is Amazon’s own operating system, and React is the stack it supports. The practical consequence is commercial, not academic. An existing Android TV app is not a cheap port to a Vega device, it is a rebuild, and a team that plans around the old assumption finds out late.

• Video playback on Fire TV

  Playback is the heart of most Fire TV apps. I cover HLS and DASH, live streams and catch-up, subtitle and audio tracks, and DRM when the content is protected and has to talk to your license server. The hardware matters here: a cheap Fire TV stick has real decoder and memory limits, so this gets tested on the device rather than on an emulator that flatters it.

• Remote-first interfaces and the D-pad

  Fire TV is a ten-foot interface driven entirely by a D-pad. There is no touch, people sit far from the screen, and every element has to be reachable in a sensible focus order. I build the focus behavior so that nothing traps the viewer or strands them on a dead element, which is the difference between an app that feels native on a TV and one that feels ported.

• Amazon Appstore submission and certification

  Amazon reviews Fire TV apps against its own checklist: remote and D-pad handling, playback controls that behave, correct metadata and artwork. I build against that checklist from the start and handle the submission, so certification is a formality rather than a surprise at the end.
