Android MediaPlayer with SurfaceView Fails on Prepare() Method

I am trying to build a video player using surface view and media player. My data source is an online video and I have enabled internet permission in manifest.
However, the video does not pay but throws a warning about prepare method without any hint at what the problem is like below:
W/System.err: at android.media.MediaPlayer._prepare(Native Method)
at android.media.MediaPlayer.prepare(MediaPlayer.java:1188)
at in.sashi.androidvideoplayer.MainActivity.surfaceCreated(MainActivity.java:64)
here's my code for this purpose:
public class MainActivity extends AppCompatActivity implements SurfaceHolder.Callback, MediaPlayer.OnPreparedListener, View.OnClickListener {
private static final String TAG = MainActivity.class.getSimpleName();
private SurfaceView surfaceView;
private ImageView playIV, backIV;
private TextView videoNameTV;
private MediaPlayer mediaPlayer;
private SurfaceHolder holder;
// private static final String VIDEO_URL = "https://www.youtube.com/watch?v=vEVd0QMjCc8";
private static final String VIDEO_URL = "http://mic.duytan.edu.vn:83/FINAL.mp4";
private static final String VIDEO_NAME = "FALL HARDER | BASKETBALL MOTIVATION";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
surfaceView = findViewById(R.id.surfsceView);
playIV = findViewById(R.id.playIV);
backIV = findViewById(R.id.backIV);
videoNameTV = findViewById(R.id.videoNameTV);
videoNameTV.setText(VIDEO_NAME);
backIV.setOnClickListener(this);
playIV.setOnClickListener(this);
holder = surfaceView.getHolder();
holder.addCallback(this);
surfaceView.setKeepScreenOn(true);
mediaPlayer = new MediaPlayer();
}
#Override
public void surfaceCreated(SurfaceHolder holder) {
mediaPlayer.setDisplay(holder);
try {
mediaPlayer.setDataSource(VIDEO_URL);
mediaPlayer.prepare();
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
} catch (IOException e) {
e.printStackTrace();
}
}
#Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
}
#Override
public void surfaceDestroyed(SurfaceHolder holder) {
}
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
#Override
public void onClick(View v) {
switch (v.getId()){
case R.id.backIV:
onBackPressed();
break;
case R.id.playIV:
if (mediaPlayer.isPlaying()){
Log.d(TAG, "Pause Clicked");
mediaPlayer.pause();
playIV.setImageResource(R.drawable.play);
} else {
Log.d(TAG, "Play Clicked");
mediaPlayer.start();
playIV.setImageResource(R.drawable.pause);
}
break;
}
}
#Override
protected void onPause() {
super.onPause();
collect();
}
private void collect() {
if (mediaPlayer != null){
mediaPlayer.release();
mediaPlayer = null;
}
}
}
Can anyone help me to figure this out? Thanks.

Use mediaplayer object which is being defined globally.
#Override
public void onPrepared(MediaPlayer mp) {
mediaPlayer.start();
}

How about this?
#Override
public void surfaceCreated(SurfaceHolder holder) {
mediaPlayer.setDisplay(holder);
try {
mediaPlayer.setDataSource(VIDEO_URL);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.prepareAsync();
} catch (IOException e) {
e.printStackTrace();
}
}

Android video playback issues

I have bit of trouble playing back video in my app. I have the very similar code as below playing back my audio files, however, when I try to play video I'm not seeing a picture, I can still hear the narration but no video. Just to exclude encoding, I dropped in my assets a file from my cell that was created on my cell and I was trying to play it back using the above method without luck. Any thoughts would be appreciated, Thank you.

Audio Streaming Seekbar Hides while song is playing

I can't find a way to stop hiding the seekbar. As soon as the song plays the seekbar hides after 2-3 sec. I am really new into this so not really sure how I can approach to this issue. I tried putting mediaController.show() into my methods when the song is playing but no luck. I found this code from a Youtube Channel below is the code:

adapter = new MainArrayAdapter(MainActivity.this, array_list_music);
setListAdapter(adapter);

setLooping don't work in my videoplayer

I am a Android newbie. I want to design my personal videoplayer to play streaming music, so I use MediaPlayer and SurfaceView. The project plays streaming video successfully, but it can't be setloop. I have google many articles and read Android Developer. I can't figure out why mediaPlayer.setLooping(true) don't work here. Thanks^^
mediaPlayer.reset();
mediaPlayer.setDataSource(videoUrl);
mediaPlayer.setLooping(true);
mediaPlayer.prepare();

I had this problem and solved it by setting the type using this depreciated method.
holder.setType(SurfaceHolder.SURFACE_TYPE_PUSH_BUFFERS);
Worth a try, and if it works you could investigate why the type isn't automatically set as it is supposed to be.

I had the same problem and it was due to the surface not being ready to play back video.
You should try and call playVideo() from the surfaceCreated() handler.
public void surfaceCreated(SurfaceHolder holder) {
runOnUiThread(new Runnable(){
public void run(){
playVideo();
}
});
}

I had this problem and solved it by adding in my release function visible=gone to surfaceview:
public void release() {
if (mMediaPlayer != null) {
setVisibility(View.GONE);
mMediaPlayer.reset();
mMediaPlayer.release();
mMediaPlayer = null;
mCurrentState = STATE_IDLE;}
}
and set visible=visible in onprepared function:
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
audio=false; video=false; int ty=mp.getTrackInfo().length;
for (int i=0; i<ty;i++)
{
if (mp.getAudioTrack()>-1) {audio=true;}
if (mp.getVideoTrack()>-1) {video=true;}
}
if (((audio==false)&&(skip==true))||((video==false)&&(skip2==true))||((video==true)&&(skip4==true)))
{ notifybar("...");
nexttr();} else {
if (vis==true) {
if (video==false) {
if (mVisualizerView.getVisibility()!=View.VISIBLE) {mVisualizerView.setVisibility(View.VISIBLE);}
mVisualizerView.link(videoView.getAudioSessionId());
vis2=true;
} else if (vis2==true){
mVisualizerView.release();
mVisualizerView.setVisibility(View.GONE);
vis2=false;
}}
//this
if (video==true) {
if (videoView.getVisibility()!=View.VISIBLE) {videoView.setVisibility(View.VISIBLE);}
} else {if (videoView.getVisibility()!=View.INVISIBLE) {videoView.setVisibility(View.INVISIBLE);}
}
