Android Question Error generating R file after "cleaning" Android folder

[Didier9]

I had to do some cleanup on my machine (running out of disk space) so I deleted the Android TV and Intel Atom System Images and Google APIs since I do not intend to use these.

Either that was misguided, or I also deleted something else I should not have...
I am now getting this error when compiling my project:

B4A Version: 8.00
Parsing code.    (0.08s)
Compiling code.    (0.44s)
Compiling layouts code.    (0.05s)
Organizing libraries.    (2.50s)
Generating R file.    Error
ERROR: In <declare-styleable> FontFamilyFont, unable to find attribute android:font
ERROR: In <declare-styleable> FontFamilyFont, unable to find attribute android:fontStyle
ERROR: In <declare-styleable> FontFamilyFont, unable to find attribute android:fontWeight

I have re-run the SDK manager and it seems I have everything I should need. I have not tried to restore the Atom and Android TV stuff and I am not planning to unless someone is positive I need them even if I do not plan to develop for these targets.

Any help appreciated.

Try to delete the complete SDK folder and install it again.

Try to delete the complete SDK folder and install it again.

Trying to keep disk space at a minimum, I am developing around Android 5.1 and 6.0. No Android Wear or Android TV or Atom. What SDK's should I install?
Is it safe to simply leave those items unchecked?

Install all the recommended items and nothing more.

Thank you everybody, I am reinstalling the SDK. I must have deleted something I was not supposed to.
