Answer 1

I guess you implemented an attr.xml file with a line <attr name="font">. Since Android 8.0 comes with a new feature called 'Fonts in XML' this might be the reason for your Error. You could change the name of the attribute to e.g. <attr name="font_name"> and probably in all your custom views and layout xmls, too. Or just use the new feature ;)

Answer 2

Try adding in your gradle.properties

android.enableAapt2=false
