This activity crashes on startup

```
package rian.derous;

import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.widget.Toast;

public class TargetOverviewActivity extends Activity {

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

@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.options_menu, menu);
        return true;
    }

    public void createTarget() {
        Toast toast = Toast.makeText(this, "create Target", Toast.LENGTH_SHORT);
        toast.show();
    }

    public void refreshTarget() {
        Toast toast = Toast.makeText(this, "refresh Target", Toast.LENGTH_SHORT);
        toast.show();
    }

    public void deleteAllTargets(){
        Toast toast = Toast.makeText(this, "delete Target", Toast.LENGTH_SHORT);
        toast.show();
    }

```

}

I think there's something wrong with the onCreateOptionsMenu, when i put that piece of code in comment it does not crash on startup. 

Followed all the steps in our Android Course handbook... Anyone that can help me please? Thanks a lot!

menu file in the menu folder

```
   <?xml version="1.0" encoding="utf-8"?>
        <menu xmlns:android="http://schemas.android.com/apk/res/android" >
        <item android:id="@+id/createTarget" android:title="Create" android:onClick="createTarget"></item>
        <item android:id="@+id/refreshTarget" android:title="refresh" android:onClick="refreshTarget"></item>
        <item android:id="@+id/deleteAllTargets" android:title="Delete All" android:onClick="deleteAllTargets"></item>

    </menu>

```
