I don't think it's Android TV. It's probably just Android.
Correct: Operating System Android 10.0 Pie
AU$20 with free shipping!
Oh wait, I hadn't select an item from the drop down list. AU$73.89 for the 4/64GB version. The keyboard is AU$20.
May as well buy a nVidia Shield. Wait. No. Those things are AU$300 to AU$400 in Australia. Good buy Maid!
The specs write-up is pretty dodgy though. Who knows what they would actually deliver. If it is actually:
Rockchip RK3318 Quad Core 64Bit Cortex-A53 CPU, Penta-Core Mali-450 up to 750Mhz+ GPU, 4GB RAM and 64GB ROM, 4K H.265 Hardware Video Decode and 4K Output, 2.4G / 5G WiFi with expanded Storage via a Supports TF Card, up to 128GB and Android 10.0 Pie, it could be okay.
JRiver for Android should still run on it, just using the Mobile version. If it can connect to the Play Store to install it.
