Developer KonstaT has recently compiled a build of Android TV 13 for the Raspberry Pi. This ported version of Android TV is based on the third-party ROM Lineage OS and Android TV 13 Beta (not yet released), with a security patch for November 2022.
While the port lacks key features like video hardware acceleration and Cast, it is compatible with the Gapps package, which means you can get the Play Store, YouTube, and other key Google services up and running.
Interested users can download this compiled version and install it on Raspberry Pi 4 or Raspberry Pi 400, the new cost-effective personal portable Linux computer “in a keyboard”. However, to install this version, you need to set aside at least 2GB of space.
