IIRC, Pioneer and Kenwood are pretty much like DeWalt and Black & Decker. Same guts, different skin. Either way, both are good at the consumer level. Of the two items referenced, the Pioneer states that it runs on Android, but the ad does not give the OS version number which makes this claim a little suspect. Best bets are do dig into the actual vendor's information instead of the Jungle's listing.
Crutchfield carries Boss products, so implicitly they are at least worthwhile.
Joying had a good reputation a few years ago for Chineseum carputers running Android. Do not know about current reputation as things change quickly in that world.
One thing to recognize is that the Android carputer might take a long time for it to boot-up and start working. As opposed to a more simplistic radio which comes alive almost as quickly as when it gets voltage. Some carputer manufacturers have a "cheat" for booting up fairly quick, but it means that the unit goes into a sleep mode rather than actually going completely offline. Unless I am missing something, sleep mode will continuously draw some power and might need mitigation if the vehicle sits for a week or so without use. If it is necessary to defeat the quick-start "cheat" by outright turning the carputer Off to keep it from draining the vehicle's battery, then the carputer will need to go through the lengthy startup process.
I also wanted an Android based carputer and got something from Eincar about 4 years ago. Goal was to add vehicle monitoring, offline navigation, and anything else that Android offers. Tried out a hybrid approach of a flip-out monitor which can give the landscape of a Double DIN unit but only needs a Single DIN housing. While the concept is exactly what I want, Eincar's product is meh, and so was the after sales support. Installation manual was a Chenglish mess where I was supposed to hook one of the harness's wires to the vehicle's "ACC - Adaptive Cruise Control" wire. (Ummmmm.... No! That is not what ACC means in this application.) While Eincar stated that navigation data was free for life, I have yet to figure out how to get the data from them and gave-up after a couple E-mail support attempts. Only thing I like about the end result is that I can watch OTA TV via a USB adapter / antenna when waiting to give somebody a ride.
I looked into going the Bluetooth dongle and tablet approach, but backed away as it means that every time I start the truck, I have to separately reach-out and start / initiate the tablet. Same for when stopping the truck. No thanks, I'm lazy. Although, if I did more long distance driving, the dongle and tablet approach might have more appeal.
