Android TV and Fire TV app engineering for streaming teams

Senior engineers who build and fix the hard parts of a streaming app on Android TV, Google TV and Fire TV: playback, DRM, live channels, performance on small devices and getting through store review.

What we work on

Playback with Media3 and ExoPlayer
HLS and DASH, live and on demand: adaptive bitrate, startup time, rebuffering, subtitles and audio tracks, and recovery from network errors.
DRM with Widevine and PlayReady
License requests, secure playback paths and the device differences between Android TV models and Fire OS versions.
FAST and live channel apps
Linear channels with a program guide, live streams with server-side ads, and channel changes that feel quick on a remote.
Store review and certification
Preparing Android TV apps for Google Play review and Fire TV apps for the Amazon Appstore: TV quality guidelines, launcher and banner requirements, remote navigation.
Performance on streaming devices
Memory, startup and dropped frames on streaming sticks and older TVs, where a phone-sized app runs out of room.
Interfaces built for the remote
Compose for TV and Leanback, focus that never gets lost, text readable from across the room.

Start with a playback audit

A fixed-scope review of your Android TV or Fire TV app, delivered in one to two weeks for a fixed price agreed before we start.

  • Playback: startup, bitrate switching, rebuffering and error handling on real devices
  • DRM: license flow and secure playback on the devices you support
  • Performance: memory, frame drops and cold start on low-end hardware
  • Store readiness: what Google Play and the Amazon Appstore review will check

You get a written report with the problems ranked by impact and the fixes for each. If you want, our engineers then make the fixes with your team.

How we work with you

On your team, in your hours

Engineers across South America work between UTC-5 and UTC-3, so their day overlaps yours.

A project or a seat

Take a scoped project such as the audit, or add a senior engineer to your team by the month.

Direct, no subcontracting chain

You talk to the engineer who does the work.

Video only

We focus on streaming apps, so playback and DRM problems are the everyday work, not an edge case.
