import java.util.Random;

public class FunFactsActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts);

    // Declare our View variables and assign them the views from the layout file
    final TextView factLabel = (TextView) findViewById(R.id.factTextView);
    Button showFactButton = (Button) findViewById(R.id.showFactButton);
    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {

            }
            // Update the label with our dynamic fact
            factLabel.setText("");

It looks like you've got an extra '}' in the onClick method. Also, the FactBook class should be in the same folder as FunFactsActivity.

public class FunFactsActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_fun_facts);

        // Declare our View variables and assign them the views from the layout file
        final TextView factLabel = (TextView) findViewById(R.id.factTextView);
        Button showFactButton = (Button) findViewById(R.id.showFactButton);
        View.OnClickListener listener = new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                }  // <-- Try deleting this <-----------------------------
                // Update the label with our dynamic fact
                factLabel.setText("");
            }
        };
        showFactButton.setOnClickListener(listener);
    }
}

Dude you are a life saver. I comb that code constantly and I don't believe I missed that. What can I say about fresh eyes and experience? I don't think I got to the part about moving the fun fact.

Thank you soooooo very much Ben

I've tried cleaning cache, rebuilding etc. nothing worked. I'm almost at the point of deleting android studio.

Can anyone please help!! I've been trying solutions on my own. Searching the web constantly. I cannot move on from this point.
