    <p>I am making a custom video player for which i am using surfaceview along with video player, but when I run the application, it just displays black screen and plays audio. </p> <p>My Code: </p> <pre><code>public class MainActivity extends Activity implements SurfaceHolder.Callback { private SeekBar seekbar; private ImageView ivPlay; private SurfaceView surfaceView; private SurfaceHolder surfaceHolder; private MediaPlayer mediaPlayer; private Handler mHandler; private Utilities utils; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initObjects(); playVideo(); } private void initObjects() { seekbar = (SeekBar) findViewById(R.id.sbVideo); seekbar.setOnSeekBarChangeListener(seekbarChangeListener); mHandler = new Handler(); utils = new Utilities(); ivPlay = (ImageView) findViewById(R.id.ivPlay); ivPlay.setOnClickListener(new OnClickListener() { @Override public void onClick(View view) { if (mediaPlayer.isPlaying()) { if (mediaPlayer != null) { mediaPlayer.pause(); // Changing button image to play button ivPlay.setImageResource(R.drawable.ic_media_play); } } else { // Resume song if (mediaPlayer != null) { mediaPlayer.start(); // Changing button image to pause button ivPlay.setImageResource(R.drawable.ic_media_pause); } } } }); surfaceView = (SurfaceView) findViewById(R.id.svVideoSurface); surfaceHolder = surfaceView.getHolder(); surfaceHolder.addCallback(this); surfaceHolder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS); mediaPlayer = new MediaPlayer(); mediaPlayer.setDisplay(surfaceHolder); } public void playVideo() { // Play song Uri uri = Uri .parse("android.resource://com.videoplayer.demo/raw/title_video1"); try { mediaPlayer.reset(); mediaPlayer.setDataSource(MainActivity.this, uri); mediaPlayer.prepare(); mediaPlayer.start(); // Changing Button Image to pause image ivPlay.setImageResource(R.drawable.ic_media_pause); // set Progress bar values seekbar.setProgress(0); seekbar.setMax(100); // Updating progress bar updateProgressBar(); } catch (IllegalArgumentException e) { e.printStackTrace(); } catch (IllegalStateException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } private OnSeekBarChangeListener seekbarChangeListener = new OnSeekBarChangeListener() { @Override public void onStopTrackingTouch(SeekBar seekbar) { mHandler.removeCallbacks(mUpdateTimeTask); int totalDuration = mediaPlayer.getDuration(); int currentPosition = utils.progressToTimer(seekbar.getProgress(), totalDuration); // forward or backward to certain seconds mediaPlayer.seekTo(currentPosition); // update timer progress again updateProgressBar(); } @Override public void onStartTrackingTouch(SeekBar seekbar) { // TODO Auto-generated method stub mHandler.removeCallbacks(mUpdateTimeTask); } @Override public void onProgressChanged(SeekBar seekbar, int progress, boolean fromUser) { // TODO Auto-generated method stub } }; @Override public void surfaceChanged(SurfaceHolder holder, int arg1, int arg2, int arg3) { mediaPlayer.setDisplay(holder); } @Override public void surfaceCreated(SurfaceHolder holder) { } @Override public void surfaceDestroyed(SurfaceHolder arg0) { // TODO Auto-generated method stub } public void updateProgressBar() { mHandler.postDelayed(mUpdateTimeTask, 100); } private Runnable mUpdateTimeTask = new Runnable() { public void run() { long totalDuration = mediaPlayer.getDuration(); long currentDuration = mediaPlayer.getCurrentPosition(); // Updating progress bar int progress = (int) (utils.getProgressPercentage(currentDuration, totalDuration)); // Log.d("Progress", ""+progress); seekbar.setProgress(progress); // Running this thread after 100 milliseconds mHandler.postDelayed(this, 100); } }; @Override protected void onDestroy() { super.onDestroy(); mediaPlayer.release(); }; } </code></pre> <p>I don't know what I am doing wrong, any help would be great.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
