Do I need a touchscreen to run Android?

[chrbar]

Ok thanks Paradis and Luke, it's worked correctly with keyboard and mouse.

I meet a problem with the Play Store App: when I run it I obtain the message "this version of the app isn't compatible with your device. to fix this problem, go settings and uninstall updates for the Google Play Store app".
Does this message is common about Google Play Store app, with Android on Rock64?

I've checked settings but there is no installed update to delete!
I've cleaned cache and others things found, but the message still appears!

Install and run Android 8.1 was my first experience with the Rock64!
I've installed Android 7.1.2 to see if I meet the same problem.
I'm able to start Play Store app without error message, but I'm not able to sign in: nothing when I clik on "Sign in" button!

Do you have some advice to help me to run Play Store app on my Rock64, and be able to install new Apps on it?

Thanks
Chris
