Download infusion-tv-0.1.3-103.apk Release notes on GitHub

That link goes straight to the release asset in the canonical repository. The installer is not hosted on this website and there is no mirror of it.

Verify your download

Two independent things identify an official fission installer: its SHA-256 checksum and its signing certificate. Check both before you install. Neither depends on trusting this page.

The checksum

Download SHA256SUMS from the same release, then, in the folder that holds both files:

sha256sum infusion-tv-0.1.3-103.apk
cat SHA256SUMS

The digest printed for the installer must be exactly:

0552b6ad6f07f19ef491ca0343504d5109aeb6a6fae7b1c936841d8905d8de9a  infusion-tv-0.1.3-103.apk

The signing certificate

With the Android SDK build tools on your PATH:

apksigner verify --print-certs infusion-tv-0.1.3-103.apk

The certificate SHA-256 digest that command prints must be the one stated in that release's notes. A build with a different signer is not a fission build, whatever it claims.

Where an installer comes from

A fission installer is published only as a release asset of the canonical repository, https://github.com/Addonniss/infusion-releases. It is never hosted on this website, never mirrored, and never served from a third-party download host. A build obtained anywhere else is not official, and the signing certificate is what actually proves an installer is ours — not the address you got it from.

Requirements

An Android TV device running Android 8.0 (API 26) or newer. The primary qualification target is the NVIDIA Shield.
No account. There is no fission sign-in.
Optional, and entirely up to you: a Jellyfin server (yours) and/or the add-ons you choose to install. You can install and run fission without either, but there will be nothing to play until at least one source is connected.

There is a mobile build in the same codebase, but no mobile installer is published for the first release. Do not install the TV build on a phone.
