Android: Lets use android.R.string

I was writing a confirm dialog on android, and there was it:

    android.R.string.yes

So lets use it, why not. However my extreme imagination, for some reason, had the actual value of it being 'Yes'.
Build, run, test, boom! There was it, on the screen, a 'OK' laughing at my face.

So turns out there is a comment:

    <!-- Preference framework strings. -->
    <string name="yes">OK</string>

And they say comments are overrated...

PS: Just look at this, look deep:

    <string name="yes">OK</string>
