Android YouTube API with ActionBarSherlock (via SherlockFragmentActivity). Because the existence of youTubeBaseActivity would have you think the API is missing a YouTubeBaseFragmentActivity and youTubeBaseSupportFragmentActivity.

gistfile1.java

public class YouTubeExampleFragmentActivity extends SherlockFragmentActivity implements YouTubePlayer.OnInitializedListener {
	
	private static final String mDeveloperKey = null;	//make sure to change this to your project's API key
	
	@Override
    protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.screen_console);
		
		YouTubePlayerSupportFragment youTubePlayerSupportFragment = (YouTubePlayerSupportFragment) getSupportFragmentManager().findFragmentById(R.id.fragment);
		youTubePlayerSupportFragment.initialize(mDeveloperKey, this);
	}
	
	/*
	 * YouTubeFailureRecoveryActivity.java example stuff
	 *
	 */
	
	private static final int RECOVERY_DIALOG_REQUEST = 1;

	  @Override
	  public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
	    if (errorReason.isUserRecoverableError()) {
	      errorReason.getErrorDialog(this, RECOVERY_DIALOG_REQUEST).show();
	    } else {
	      String errorMessage = String.format(getString(R.string.error_player), errorReason.toString());
	      Toast.makeText(this, errorMessage, Toast.LENGTH_LONG).show();
	    }
	  }

	  @Override
	  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
	    if (requestCode == RECOVERY_DIALOG_REQUEST) {
	      // Retry initialization if user performed a recovery action
	      getYouTubePlayerProvider().initialize(mDeveloperKey, this);
	    }
	  }

	  public YouTubePlayer.Provider getYouTubePlayerProvider() {
		  return (YouTubePlayerSupportFragment) getSupportFragmentManager().findFragmentById(R.id.fragment_youtube);
	  }

	@Override
	public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
		if (!wasRestored) {
	      player.loadVideo("nCgQDjiotG0");
	    }
	}

I've no idea why gist is messing with the formatting like it is...
