Having trouble with Android Studio, please help!

I have just created a new project in which I am using ActivityA and ActivityB for my activity names. In addition I also named activity_layout for my layout name. When the project is created and loads up in android studio, I am receiving a error message after clicking on the first activity which is activityA. The error message states this "<identifier> expected" and will not run app. Please take a look at the code on line 27 where there is a wiggle line under a common which is causing the error. Thanks!

package Hour2App.hour2app;

import android.app.Activity; import android.os.Bundle; import android.view.Menu; import android.view.MenuItem; import android.view.View; import android.view.View.OnClickListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView;

public class ActivityB extends Activity {

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


@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu., menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}

This line of code in the code above I receive a wiggle line under the comma after the first menu.(R.menu.,)

getMenuInflater().inflate(R.menu., menu);

Hi Michael,

In your onCreateOptionsMenu() method you have the following line:

getMenuInflater().inflate(R.menu., menu);

You should have a reference to a menu like R.menu.menu_main.

If you don't want to have a menu for your application for now, you can safely delete the entire onCreateOptionsMenu() method, or alternatively add an appropriate menu.

I hope this helps.

Thanks! I have been trying to fix this issue for the last 12hours and every time I try to reference something it just turns the color red and the wiggle line is gone. I will have to do without the menu options for now I guess but i really do appreciate your feed back. Thanks again Jon, great job with such a quick response!
