Adding a new Menu Option

First of all, confirm that the current Menu looks like this:

but we want something like this:

The first thing to do is add in a new resource in strings.xml (or use Android Studio (Alt + Return) to fix the string resource error if you paste in the menu item directly)

     <string name="menuReset">Reset</string>

and then the corresponding menu item in donate.xml

     <item
        android:id="@+id/menuReset"
        android:orderInCategory="100"
        android:showAsAction="never"
        android:title="@string/menuReset"
        android:onClick="reset"/>

It's probably worth removing the 'Settings' menu item at this stage too, and its related method in the Base class. Next, edit Base.java and add in the following method stub

public void reset(MenuItem item) {}

to ensure our app won't crash when the menu loads (and looks for a method 'reset')

Run the app again and confirm you get the following Menu :

We can't implement this menu option fully yet, so for the moment, we'll just 'reset' the target amount back to zero (0) - Step 03.
