Hi we have an app in the playstore that has a module that play a stream from an url, the app works fine and we make a yearly release, but now that we are making changes, the part of the radio does not work, in any device.
Basically my code is
mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setDataSource("http://radio.promosat.com:8104/");
mediaPlayer.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mediaPlayer.prepareAsync();
}catch (Exception ex){
ex.printStackTrace();
}
I keep getting this error
E/MediaPlayer: Error (1,-2147483648)
This worked perfectly, the url that we use it's in the example code, it uses a pls file, that's where we obtained the stream url.
The error was the encoding of the stream...aacp is not supported in Android.

Currently I'm trying to simply stream a Video from some link this way:
try {
videoView = (VideoView) findViewById(R.id.videoView);
MediaController vidControl = new MediaController(this);
vidControl.setAnchorView(videoView);
videoView.setMediaController(vidControl);
videoView.setVideoPath("http://some.link/some_video.mp4");
loadingProgress.show();
videoView.requestFocus();
videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
#Override
public void onPrepared(MediaPlayer mp) {
loadingProgress.dismiss();
videoView.start();
}
});
} catch (Exception e) {
e.printStackTrace();
}
Everything is going OK, but I want to make that URL (i.e. http://some.link/some_video.mp4) secure. I mean user won't be able to download this video.
The problem is: before loading this video, the logcat is
displaying log like this:
my.app.package.name W/MediaPlayer: Couldn't open http://some.link/some_video.mp4: java.io.FileNotFoundException: No content provider: http://some.link/some_video.mp4
I have noticed:
Even the code is not going into CATCH block.
Made SIGNED App, but that LOG is still appearing.
Those logs are built into the framework MediaPlayer class. The only way I know of to remove it is to take the MediaPlayer code from AOSP, copy it to a class in your app, remove all the log statements, and use that instead of the Android MediaPlayer class.
so this is my first question here on stackoverflow, so take it easy on me ^^
Since some days I got into android developing. As a first little project I want to develop a soundboard app. Sadly I can't get the damn MediaPlayer to work. Either it gives no error and I can't hear a thing (volume maxed) or I get an error when I want to prepare the MediaPlayer.
I call the playSound(View) event, when clicking on a button. Inside the function, I'd like to play a mp3 file from the apps resources. Here is my current code following that you'll find a link where you can see, how I added the mp3 file to the apps resources. I googled a lot and tried as much as I understand right now but I can't get it to work.. Do you have any ideas what might be wrong with the code?
public void playSound(View v)
{
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setCancelable(true);
MediaPlayer mediaPlayer = new MediaPlayer();
try {
mediaPlayer.setDataSource(MainActivity.this, Uri.parse("android.resource://mypackagename/res/raw/einemetallischebitterkeit"));
mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
mediaPlayer.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
#Override
public void onCompletion(MediaPlayer mp) {
mp.stop();
mp.release();
}
});
mediaPlayer.prepare();
mediaPlayer.start();
} catch (IOException e) {
builder.setMessage(e.toString());
AlertDialog dialog = builder.create();
dialog.show();
}
}
mp3 file in app resources
You should use like this
InputStream mymp3 = getResources().openRawResource(R.raw.einemetallischebitterkeit);
Having small game to play short sound after onclick ImageButton. But after touching 10times MediaPlayer stop playing sounds on short time. After sometime it play sound again. When I look to LogCat console it show error: E/MediaPlayer(19584): error (1, -2147483648).
Please can you show me the way to find sollution to solve this problem ? Why MediaPlayer gives me error ?
I use this part of code to play Sound:
public void playAudio () {
try {
mediaPlayer = MediaPlayer.create(getBaseContext(), R.raw.trefa);
mediaPlayer.setLooping(false);
mediaPlayer.start();
mediaPlayer.setOnCompletionListener(new OnCompletionListener() {
public void onCompletion(MediaPlayer arg0) {
}
});
} catch (Exception e) {
Log.e("beep", "error: " + e.getMessage(), e);
}
}
The sollution for me is really to use SoundPool (not MediaPlayer). I have replaced my MediaPlayer with SoundPool from this tutorial: http://www.edumobile.org/android/android-programming-tutorials/sound-pool-example-in-android-development and everything is ok.
I need to play sound from sd card. I have method that must do this but it's doesn't work.
When I use this method:
public class AudioPlayService extends Service
{
MediaPlayer mMediaPlayer;
..............
public void soundplay(String adr)
{
mMediaPlayer = new MediaPlayer();
try
{
if (mMediaPlayer.isPlaying())
{
mMediaPlayer.reset();
}
mMediaPlayer.setDataSource(adr);
mMediaPlayer.prepare();
} catch (IOException e)
{
}
mMediaPlayer.start();
mMediaPlayer.setOnCompletionListener(new OnCompletionListener()
{
#Override
public void onCompletion(MediaPlayer mp)
{
mp.release();
mp = null;
}
});
}
Where String adr - it's absolute path to file on sd.
Then I call it:
AudioPlayService s = new AudioPlayService();
s.soundplay(iA.getSdDir() + "Files/Numbers/0.mp3");
and I get an err's:
12-09 13:04:13.829: E/MediaPlayer(16997): error (1, -2147483648)
12-09 13:04:13.829: E/MediaPlayer(16997): start called in state 0
12-09 13:04:13.829: E/MediaPlayer(16997): error (-38, 0)
12-09 13:04:13.839: E/MediaPlayer(16997): Error (-38,0)
I myself tried your code:
Mine worked fine when i put just "sdcard/1.mp3"
You ensure that the path is right or not
s.soundplay(iA.getSdDir() + "Files/Numbers/0.mp3");
Note:
If you are trying to make your method soundplay so as to stop previous audio and play the new audio file, then better would be not to perfom this inside that method
mMediaPlayer = new MediaPlayer();
Place this in constructor.
Otherwise each time you invoke s.soundplay(path) you will hear previous audio plus the new audio. ie,Previous one will not be stopped
player.start() put within try,catch block. Because if player not prepare your song ,still you are calling start method.start method is only called after playback is ready,
means prepare is success.Another thing is that you have to release the media player when your player is no longer.Otherwise there is so many player objects are running in back ground.
For some reason, your setDataSource() or Prepare() is failing. So after the exception, start()is giving the error, since the player is not in Prepared state. Add print statements in the catch block to know what is the exception. And move start() into the try catch block.
mMediaPlayer = new MediaPlayer();
try
{
if (mMediaPlayer.isPlaying())
{
mMediaPlayer.reset();
}
mMediaPlayer.setDataSource(adr);
mMediaPlayer.prepare();
mMediaPlayer.start();
} catch (IOException e)
{
e.printStackTrace();
}
I have mp4 and wmv movie files and need to play only sound not video screen. How to do it?? Could I get sound track from movie file??
I know if I hide the SurfaceView from screen, I can only hear sound.. but I have tried a lot but.. it is impossible.
If you have any solution to extract sound track from movie file, please let me know..
Thanks in advance.
If you are using the mediaplayer API in your app then don't call the API public void setDisplay (SurfaceHolder sh). This will ensure that only the audio is played out even if the video content is present..

Use following code, Optimize following code as per your requirement. It play video from youtube.
try {
final MediaPlayer m = new MediaPlayer();
Thread t = new Thread(new Runnable() {
public void run() {
try {
m.setDataSource("rtsp://v8.cache3.c.youtube.com/CjgLENy73wIaLwlQP1m32SiSYxMYJCAkFEIJbXYtZ29vZ2xlSARSB3JlbGF0ZWRggqG7w9aS2-1MDA==/0/0/0/video.3gp");
m.prepare();
m.start();
} catch (Exception e) {
e.printStackTrace();
}
}
});
t.start();
} catch (Exception e) {
e.printStackTrace();
}
