Android Vitamio 4.2 update 5.0 crash

Question

I updated Vitamio 4.2.2 to 5.0.0 as Google requested because of security issues in developer console. But with the same codes. Only changed Vitamio.isInitialized(getApplicationContext()); There is not error. Application was installed. But video not playing. How can i do for this?

public class MainActivity extends Activity implements MediaPlayer.OnBufferingUpdateListener, MediaPlayer.OnCompletionListener, MediaPlayer.OnPreparedListener, MediaPlayer.OnVideoSizeChangedListener, SurfaceHolder.Callback {

private static String TAG = MainActivity.class.getSimpleName();
private static String ShowTV = "http://mn-i.mncdn.com/showtv_ios/smil:showtv.smil/playlist.m3u8";";
private TextView tvLoader;
private int mVideoWidth;
private int mVideoHeight;
public MediaPlayer mMediaPlayer;
private SurfaceView mPreview;
private SurfaceHolder holder;
private boolean mIsVideoSizeKnown = false;
private boolean mIsVideoReadyToBePlayed = false;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Vitamio.isInitialized(getApplicationContext());

    if (Build.VERSION.SDK_INT < 16)
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
    else
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_FULLSCREEN);

    tvLoader = (TextView) findViewById(R.id.tvLoader);
    mPreview = (SurfaceView) findViewById(R.id.surface);
    holder = mPreview.getHolder();
    holder.addCallback(this);
    holder.setFormat(PixelFormat.RGBA_8888);
}
