At Following line :-

private GoogleAccountCredential credential;
 credential = GoogleAccountCredential.usingOAuth2(MainActivity.this,
                DriveScopes.DRIVE);

You need to add the Google Play Services jars to your project, as explained in Step 3 of the quickstart guide you are following.
