Error:(15, 5) error: method does not override or implement a method from a supertype

It appears my code is matching up with the vid, but I have red squiggles under @Override I have searched for solutions to resolve this, but have not found an answer yet. Tried clean and rebuild, restarted studio.Thanks for your help in advance! 

@Override
protected void onCreate(Bundle savedInstanceState, final ActionBar.Tab factLabel) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts99);


    // Declare our view variables and assign them the Views from the layout file
    final TextView factLable = (TextView) findViewById(R.id.factTextView);
    Button showFactButton = (Button) findViewById(R.id.showFactButton);
    View.OnClickListener listener = new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            // The button was clicked, so update the fact label with a new fact
            String fact = "Ostriches can run faster than horses";
            factLabel.setText(fact);
        }

    };
    showFactButton.setOnClickListener(listener);

Corrected misspelling, but now get

@Override
protected void onCreate(Bundle savedInstanceState, final ActionBar.Tab factLabel) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts99);


    // 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) {
            // The button was clicked, so update the fact label with a new fact
            String fact = "Ostriches can run faster than horses";
            factLabel.setText(fact);
        }

    };
    showFactButton.setOnClickListener(listener);

squiggle on factLabel right under the //declare our view.... and error Error:(22, 24) error: variable factLabel is already defined in method onCreate(Bundle,Tab)

Hi Darin

@Override
protected void onCreate(Bundle savedInstanceState) { //You added a factlabel declaration in here by mistake
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_fun_facts99);


    // 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) {
            // The button was clicked, so update the fact label with a new fact
            String fact = "Ostriches can run faster than horses";
            factLabel.setText(fact);
        }

    };
    showFactButton.setOnClickListener(listener);

I think you added the factlabel declaration as a paramater for the method call by mistake. The code above has removed this.

Hope this helps

Daniel
