I'm having trouble understanding how to implement a "Result Callback". Can someone point me in the right direction?

I am following this guide on google for setting up Google Play Game Services for Android.

At the section for implementing a ResultCallback it says:

In the snippet, MatchInitiatedCallback is a class that implements the ResultCallback interface. You can attach this object to the GoogleApiClient so that your game is notified whenever a match is initiated. To see how the MatchInitiatedCallback is implemented, see Taking the first turn.

public class MatchInitiatedCallback implements
    ResultCallback<TurnBasedMultiplayer.InitiateMatchResult> {

@Override
public void onResult(TurnBasedMultiplayer.InitiateMatchResult result) {
    // Check if the status code is not success.
    Status status = result.getStatus();
    if (status.isSuccess()) {
        showError(status.getStatusCode());
        return;
    }

    TurnBasedMatch match = result.getMatch();

    // If this player is not the first player in this match, continue.
    if (match.getData() != null) {
        showTurnUI(match);
        return;
    }

    // Otherwise, this is the first player. Initialize the game state.
    initGame(match);

    // Let the player take the first turn
    showTurnUI(match);
 }
}

I created a class called "MatchInitiatedCallback" but i don't know what to do with it. I would like to just start a new intent.

    // Let the player take the first turn
    showTurnUI(match);

I tried starting a new intent at the showTurnUI(), but this MatchInitiatedCallback won't let me start a new intent i guess because it doesn't inherit from Activity...(?)

I don't understand these callback things well enough to know where to begin, could anyone point me in the right direction?
