I have an android app that streams audio by URL (its an infinite stream) and it works. But I need to allow users to rewind X seconds and forward X seconds ( you can only forward if you rewind before )
here's the code

audioManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);
volumeSeekbar.setMax(audioManager
.getStreamMaxVolume(AudioManager.STREAM_MUSIC));
volumeSeekbar.setProgress(audioManager
.getStreamVolume(AudioManager.STREAM_MUSIC));
volumeSeekbar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener()

#Override

i am designing a mediaplayer from scratch so what i am getting stuck in is that when the song finish to play i want to set seekbar to initial value
i know this can be done with
seekBar.setProgress(0)
but this don't work with me and i want the play button to switch back to pause button and if the user play song again than the song will be played normally
here is my code of media player and hope you tell me what is the logic and how to place it
public class MusicPlayerActivity extends AppCompatActivity implements Runnable,
SeekBar.OnSeekBarChangeListener {

seekBar.setEnabled(false);
}else{
playpause.setImageResource(R.drawable.play);
mp.seekTo(len);
mp.start();
seekBar.setEnabled(true);
}
isPlaying = !isPlaying;
}
});

try {
mp.setDataSource(url);
} catch (IOException e) {
e.printStackTrace();
}
try {

} catch (IOException e) {

//if(mp.isPlaying()) mp.stop(); mp.release();

#Override
public void onBackPressed() {
Intent mainActivity = new Intent(Intent.ACTION_MAIN);
mainActivity.addCategory(Intent.CATEGORY_HOME);
mainActivity.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(mainActivity);
}
}
You are not setting the listener : seekbar.setOnSeekBarChangeListener(this)
Add seekbar.setOnSeekBarChangeListener(this); in your onCreate otherwise the onProgressChanged() does not get called.
To reset progress bar look into the following approach:
Set OnCompletionListener on your media player instance. When the media file completes playing, your can carry out the required actions in OnCompletion(MediaPlayer mp) callback function.
Adding following code snippet before mp.start() should work for you.
mp.setOnCompletionListener(new OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
seekBar.setProgress(0); // sets seekbar to initial position.
toggleViews();//implement this function to toggle your play/pause button
}
});
I am in the process of building an android app for a local community radio station and I am getting this error in the LogCat:

Any help would be appreciated, this is my first time doing this type of development.
I had the same problem... It has to be just the IP address with port number.
For this:
private final String URL = "http://37.187.193.36:8002/listen.pls";
Replace with:
private final String URL = "http://37.187.193.36:8002/";
So I got it to work finally in the end....First of all, thanks to #TennyTech.com for the little hint.
So to help ye people out, I will have an ans up on my github repo by tonight hopefully :) But do keep an eye out.
Hope this helps,

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:
public class MainActivity extends ListActivity implements OnPreparedListener,
MediaController.MediaPlayerControl {
private static final String TAG = "AudioPlayer";
private ListView list;
private MainArrayAdapter adapter;
private MediaPlayer mediaPlayer;
private MediaController mediaController;

private Handler handler = new Handler();
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
list = getListView();
mediaPlayer = new MediaPlayer();
mediaPlayer.setOnPreparedListener(this);
mediaController = new MediaController(this);
ArrayList<String> array_list_music = new ArrayList<String>();
array_list_music.add("Sammy Kaye And His Orchestra" + " ### "
+ "Minka (1941)" + " ### "
+ "http://incoming.jazz-on-line.com/a/mp3w/1941_149.mp3");
adapter = new MainArrayAdapter(MainActivity.this, array_list_music);
setListAdapter(adapter);
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Object item = getListView().getItemAtPosition(arg2);
String the_list_item = item.toString();
Toast.makeText(MainActivity.this,
"You clicked " + the_list_item, Toast.LENGTH_LONG)
.show();
String[] aux = the_list_item.split(" ### ");
String url_to_play = aux[2];
playAudio(url_to_play);
}
});
}
private void playAudio(String url_to_play) {
//----- stop & reset
try {
mediaPlayer.stop();
mediaPlayer.reset();
} catch (Exception e) {

}
try {

mediaPlayer.prepare();
mediaPlayer.start();

I got stuck with one requirement i need to play a media file in android.I will post the screen shot of the page
Actual requirement is the user wants to play the audio file in his recordings list.The recordings list are shown through list adapter.I want to display the play progress of the audio file on the same page(as like shown in the screen shot).
Iam pasting the code which i have tried.
public class RecordingActivity extends ListActivity implements MediaPlayerControl {

super.onCreate(savedInstanceState);
setListAdapter(new FirstAdapter(this, recordings));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
showPopup(RecordingActivity.this, p);
// get selected items
mMediaPlayer = new MediaPlayer();
mMediaController = new MediaController(this);
mHandler = new Handler();
mMediaController.setMediaPlayer(RecordingActivity.this);
OUTPUT_FILE = Environment.getExternalStorageDirectory()+"/recorder.mp3";
try{
mMediaPlayer.setDataSource(OUTPUT_FILE);
mMediaPlayer.prepare();
}
catch(Exception e){
}
mMediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mHandler.post(new Runnable() {
public void run() {
mMediaController.show(10000);

}
});
}
});
}
private void showPopup(final Activity context, Point p) {
int popupWidth = 200;
int popupHeight = 150;
// Inflate the popup_layout.xml
RelativeLayout viewGroup = (RelativeLayout) context.findViewById(R.id.reviewlist);

// Creating the PopupWindow
final PopupWindow popup = new PopupWindow(context);
popup.setContentView(layout);
popup.setWidth(popupWidth);
popup.setHeight(popupHeight);
popup.setFocusable(true);
// Some offset to align the popup a bit to the right, and a bit down, relative to button's position.

// Clear the default translucent background
popup.setBackgroundDrawable(new BitmapDrawable());
// Displaying the popup at the specified location, + offsets.
popup.showAtLocation(layout, Gravity.NO_GRAVITY,p.x+OFFSET_X,p.y+OFFSET_Y);
// Getting a reference to Close button, and close the popup when clicked.

}
#Override

}
}
The problem am facing is i am able to play the audio file ,but it is not showing any popup layout.
Media player
MediaPlayer mp = new MediaPlayer();
// Set data source -
setDataSource("/sdcard/path_to_song");
// Play audio
mp.start();
// Pause audio
mp.pause();
// Reset mediaplayer
mp.reset();
// Get song length duration - in milliseconds
mp.getDuration();
// Get current duration - in milliseconds
mp.getCurrentDuration();
// Move song to particular second - used for Forward or Backward
mp.seekTo(positon); // position in milliseconds
// Check if song is playing or not
mp.isPlaying(); // returns true or false
Hope this will give you some solution. Refer this link. It will solve your problem

public void onCreate(Bundle savedInstanceState) {

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();
The code includes two parts: 1.Test_Videoplayer.java 2.Player.java
