Failed to sign APK, but gradle builds work?

I have gradle builds working but do not know how to run them on my Android device, but I would really like to be able to just use an APK file. I just made a new keystore in unity and I know the password is correct, its giving me this error:

CommandInvokationFailure: Failed to sign APK package.

I had to install an sdk and jdk from past versions for my game to run.
