Right now there is no tablet support. But Google has partnered with all major manufacturers and so most of them that come out this year will have full ARCore support and I'm sure tablets will be included. This is from Google's
blog:
Quote: "ARCore, Google’s augmented reality SDK for Android, is out of preview and launching as version 1.0. Developers can now publish AR apps to the Play Store, and it’s a great time to start building. ARCore works on 100 million Android smartphones, and advanced AR capabilities are available on all of these devices. It works on 13 different models right now (Google’s Pixel, Pixel XL, Pixel 2 and Pixel 2 XL; Samsung’s Galaxy S8, S8+, Note8, S7 and S7 edge; LGE’s V30 and V30+ (Android O only); ASUS’s Zenfone AR; and OnePlus’s OnePlus 5). And beyond those available today, we’re partnering with many manufacturers to enable their upcoming devices this year, including Samsung, Huawei, LGE, Motorola, ASUS, Xiaomi, HMD/Nokia, ZTE, Sony Mobile, and Vivo."
