Hi Charles! Sorry you're having trouble here. Check out the last line from the error you posted, as it contains a clue to the problem:

C:\Users<user>\AndroidStudioProjects\FunFacts\app\build\intermediates\res\debug\layout\activity_fun_facts.xml:1: error: Error: Resource id cannot be an empty string (at 'id' with value '@+id/').

This has happened to a few students...it looks like you somehow created a blank ID for one of the views in your layout. If you check out the XML view for activity_fun_facts.xml, you'll see exactly the part at the end of this error: @+id/. We don't talk about this in detail in the course, but that's the prefix to declare an ID for a View. After the slash is where we add the ID. You'll need to add an ID wherever this line is occurring. You might need to use a specific ID if you are trying to reference it in your Activity file, otherwise you can name the ID whatever you want.
