I am getting a few errors when I try to sync gradle. I am extremely new to android coding.

Gradle Console

first bit of values.xml (limited on characters, but don't worry it hasn't been touched)

Also, I am getting 2 error on values.xml:

and

Resource registered by this URI is not recognized

Resource registered by this URI is not recognized

Any help will be greatly appreciated!

From Your Error Log seems Like you are getting this error because of

error: style attribute 'attr/roundSelector (aka
com.example.adend.timetable:attr/roundSelector)' not found.

So Please check this

@drawable/round_selector_dark

you have this round_selector_dark in your drawable or not .

there are multiple errors and all are regarding your style.xml

So double check your style.xml elements.

I have been struggling with this following error: AGPBI: "kind":"error","text":"error: style attribute u0027attr/preferenceTheme (aka com.example.android.project:attr/preferenceTheme)u0027 not found.", ...

Then I figured, since I was not using the PreferenceFragmentCompat, I had removed a seemingly unnecessary dependency from by build.gradle: 'com.android.support:preference-v4:27.1.1' I have put that dependency back and am feeling lonely as ever again.
