VideoView Playing a file while it is received via socket

I have an App that is receiving a video file from another App that is working as a Server. While the App is saving the file received on the socket, the video stream starts playing the file (which is under construction). In the code sample, after I press the btnStream, I press the btnPlay and App runs successfully. However, if the playing rate is greater than the download rate, an error will occur. I want to avoid this case. So I need to have a listener on the Video Playing that will pause the videoview when it predicts that this error will occur. I know a solution where if I know the video size, I can counter the bytes received and monitor how many seconds have been buffered and see if the videoview should pause or not. However, is it possible to do it without knowing the video file size? Or having two threads that depends on each other? Thanks.
Note: the VideoView used is a custom one where it can play FileDescriptor.
btnStream.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String s = etURL.getText().toString();
String ip = "10.0.0.24";
int port = 7878;
mct= new VideoDownloadTask(ip,port);
mct.execute();
}});

} catch (FileNotFoundException e) {

I applied a simple solution that resolved the problem. I am sharing it if anyone is having the same problem. The solution was simply to add an error listener to the videoView that will block the error popups and pauses the video.
mVideoView.setOnErrorListener(new OnErrorListener(){
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// TODO Auto-generated method stub
statusText.setText("ERROR PLAYING VIDEO");
mVideoView.pause();
return true;
}
});

pDialog = new ProgressDialog(PlayVideoActivity.this);
pDialog.setTitle("Gajacharitra");
pDialog.setMessage("Buffering video...");
pDialog.setIndeterminate(false);
pDialog.setCancelable(false);
pDialog.show();
try {
// Start the MediaController
mediacontroller.setAnchorView(mVideoView);
// Get the URL from String VideoURL
Uri video = Uri.parse(mVideoURL);
mVideoView.setMediaController(mediacontroller);
mVideoView.setVideoURI(video);
mVideoView.requestFocus();
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
// Close the progress bar and play the video
public void onPrepared(MediaPlayer mp) {
pDialog.dismiss();
mVideoView.start();
}
});
mVideoView.setOnErrorListener(new MediaPlayer.OnErrorListener() {
#Override
public boolean onError(MediaPlayer mediaPlayer, int i, int i1) {
mVideoView.pause();
pDialog.dismiss();
Toast.makeText(PlayVideoActivity.this, "Can't play this video.", Toast.LENGTH_LONG).show();
finish();
return true;
}
});
} catch (Exception e) {
/*Log.e("Error", e.getMessage());
e.printStackTrace();*/
pDialog.dismiss();
Toast.makeText(PlayVideoActivity.this, "Can't play this video.", Toast.LENGTH_LONG).show();
finish();
}

Android: cant play the mp3 file from the given url

I want to know about the android media player. I have designed a media player such that it will take the url and play the song when i select the play button when i tested in my tablet it is not working if i select the button it will not play or give the error neither crashing is happening.
i have a question in mind that whether the authentication is needed like example while researching i saw the android.drm etc because i am linking the url to the server
can anyone help me in this
i have posted the code which i have used even the logcat details as well. logcat will tell about GPU so i tested in my tablet as well still i cant listen to the mp3 file
public class MainActivity extends Activity
{
static final String AUDIO_PATH = "url";
private MediaPlayer mediaPlayer;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
public void doClick(View view) {
switch(view.getId()) {
case R.id.play:
try {
playAudio(AUDIO_PATH);
} catch (Exception e) {
e.printStackTrace();
}
break;
case R.id.stop:
if(mediaPlayer != null) {
mediaPlayer.stop();
}
break;
}
}
private void playAudio(String url) throws Exception
{
killMediaPlayer();
mediaPlayer = new MediaPlayer();
mediaPlayer.setDataSource(url);
mediaPlayer.prepare();
mediaPlayer.start();
}
#Override
protected void onDestroy() {
super.onDestroy();
killMediaPlayer();
}
private void killMediaPlayer() {
if(mediaPlayer!=null) {
try {
mediaPlayer.release();
}
catch(Exception e) {
e.printStackTrace();
}
}
}}
main.xml file is as shown below
<EditText

in logcat there are no errors as such excluding Gpu

MediaPlayer mediaPlayer = new MediaPlayer();
mp.setDataSource(context, Uri.parse("http://www.domian.com/ola.mp3"));
mp.setAudioStreamType(AudioManager.STREAM_MUSIC);
mp.prepare();
mp.setOnPreparedListener(new OnPreparedListener() {
#Override

mp.start();
}
});
mediaPlayer.setOnErrorListener(new OnErrorListener() {
#Override
public boolean onError(MediaPlayer mp, int what, int extra) {
// Display error
return false;
}
});

Try this:
MediaPlayer mp=new MediaPlayer();
try {
mp.setDataSource(url);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block

}
try {

} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
mp.setLooping(true);
}

Unable to set string to object

got my code working. Just having a little trouble with one part.
public void picksound(){
Intent mIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(mIntent, 1);
}
public void onActivityResult(int requestCode, int resultCode, Intent mIntent) {
if (resultCode == RESULT_OK && null != mIntent) {
if (requestCode == 1) {
Uri selectedRing = mIntent.getData();
}
}}
private void playSong(String selectedRing){
MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource(selectedRing);
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
mp.prepare();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
}
public void alarmmsg(){
//ringtone player
playSong(selectedRing);
//
So that's the code I am working with. When I try to call the playSong function, I am asked for a string, and the only string it seems to accept is "null". Can someone help to see what I've done wrong?

Try changing this line :
MediaPlayer mp = new MediaPlayer();
To this:
MediaPlayer player = MediaPlayer.create(this, Uri.parse("http://www.urltofile.com/file.mp3"));

Mediaplayer and finish() method

I was just testing mediaplayer in android, i started a stream in the onCreate method and I have a button that calls the finish() method. After clicking the button I can still hear the stream playing even though the activity is close, I am wondering if this is a leak of sorts and i will have to stop the player first before calling the finish() method, or if finish() method actually does not full kill the app to free up resources. Thank you for reading
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button add_function,exit_btn;
add_function = (Button) findViewById(R.id.view_chat);
exit_btn = (Button) findViewById(R.id.exit_btn);
MediaPlayer mp = new MediaPlayer();
String URL_OF_FILE = "http://stream.radiosai.net:8002/";
try {
mp.setDataSource(URL_OF_FILE);
mp.prepare();
} catch (IllegalArgumentException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IllegalStateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
mp.start();
exit_btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
finish();
}
});
}// EOF ONCREATE

Calling finish() does not kill the application, it just destroys the current Activity that you're finishing. Although I would think finishing the Activity would stop the MediaPlayer, what you should probably do in this case is override onDestroy(), and release your MediaPlayer object there. For instance:
#Override
public void onDestroy() {
if(mediaPlayer != null) mediaPlayer.release();
super.onDestroy();
}

Android MediaPlayer Service

I am looking to start a Service to keep music playing from my app when the user closes it. I have done a lot of searching around and all I am really looking for is a simple example that will allow me to start the service and music when the user presses a button. And when the user comes back to the app at some other point and presses another button then I want to bind to the service and stop the music playback. I have done a lot of searching around and I was hoping that someone could give me a clear explanation of how this all works and maybe even a code example.

to play song in Sd card using this snippet code:
public void playSong(int songIndex) {
// Play song
try {
mp.reset();
mp.setDataSource(songsListingSD.get(songIndex).get("songPath"));
mp.prepare();
mp.start();
// Displaying Song title
String songTitle = songsListingSD.get(songIndex).get("songTitle");
songTitleLabel.get().setText(songTitle);
// Changing Button Image to pause image
btnPlay.get().setImageResource(R.drawable.ic_media_pause);
// set Progress bar values
songProgressBar.get().setProgress(0);
songProgressBar.get().setMax(100);
// Updating progress bar
updateProgressBar();
} catch (IllegalArgumentException e) {
e.printStackTrace();
} catch (IllegalStateException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
}
more example code for android mediaplayer run in service,you can make reference to this tutorial.
