Android Studio Bug

So I made a new project, didn't change anything in the .java file and its giving me an error message. This is my code (unchanged)

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fun_facts);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });
    }

It is this line that supposedly has the problem:

       FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {

It's looking for something in the XML which isn't there. I'm going to guess you removed some stuff. Just delete that section of code and the error will go away.

I did not change or delete anything in the XML file, I literally just created the project. If I delete that line of code, 31 other errors are present in the rest of the .java file after that line that was deleted.
