I have a pixel 2 xl so your mileage may vary, but it took me 3 times to get Waydroid to install. I used Waydroid helper, but the installation is extremely touchy. You have to keep your screen unlocked and you cannot touch anything or even have the screen rotate during the install or it will stall. I don't recall the snippet I read that gave me the clue to do that, but once I was able to get that down and not touch the phone at all, I was able to successfully install waydroid. I just did it yesterday. 🙂
