problem with the api of youtube android

I have a dialogue that I want to show a YouTube video, I charge it in the following way

public void video(final String video) {
        final Dialog dialog = new Dialog(Leyes.this);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(R.layout.youtube_video);
        dialog.setCancelable(true);

        WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
        lp.copyFrom(dialog.getWindow().getAttributes());
        lp.width = WindowManager.LayoutParams.WRAP_CONTENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;

        youTubePlayerView = (YouTubePlayerView) dialog.findViewById(R.id.youtube_player_view);
        youTubePlayerView.initialize(getResources().getString(R.string.youtube_key), new YouTubePlayer.OnInitializedListener() {
            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
                ytp=youTubePlayer;
                ytp.loadVideo(video);
                ytp.setPlayerStateChangeListener(new YouTubePlayer.PlayerStateChangeListener() {
                    @Override
                    public void onLoading() {

                    }

                    @Override
                    public void onLoaded(String s) {

                    }

                    @Override
                    public void onAdStarted() {

                    }

                    @Override
                    public void onVideoStarted() {

                    }

                    @Override
                    public void onVideoEnded() {
                        dialog.dismiss();
                    }

                    @Override
                    public void onError(YouTubePlayer.ErrorReason errorReason) {
                        TastyToast.makeText(getApplicationContext(),"Error al cargar el video",TastyToast.LENGTH_LONG,TastyToast.ERROR).show();
                        dialog.dismiss();
                    }
                });
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
                TastyToast.makeText(getApplicationContext(),"Error al cargar el video",TastyToast.LENGTH_LONG,TastyToast.ERROR).show();
                dialog.dismiss();
            }
        });


            dialog.show();
            dialog.getWindow().setAttributes(lp);


    }

gives me the following error:

  

Caused by: java.lang.IllegalStateException: To YouTubePlayerView can   only be created with an Activity which extends YouTubeBaseActivity as   its context.

being that the class of my activity is defined as follows:

  

public class Laws extends YouTubeBaseActivity implements   AppCompatCallback {

I hope you can help me
