 |
|
hello, plusminus:
thanks for your help, i can play the mp3 file. Now I want to play from the http URL
below is my code 1:
| Java: | MediaPlayer mp = new MediaPlayer();
try {
mp.setDataSource( "http://127.0.0.1/em_ringtone1.mp3" );
if(mp!=null){
mp.prepareAsync();
mp.start();
}
} catch ( IOException e ) {
Log.e( "ioexception", "", e);
} |
code 2
| Java: | MediaPlayer mp;
Uri myUrl = Uri.parse("http://127.0.0.1/02.mp3");
mp = MediaPlayer.create(mplayer.this,myUrl);
if(mp!=null){
mp.start();
} |
====================
but i still can not play mp3 from the http URL.
could you please give me some suggestion ?
by the way, did anyone try the code from http://code.google.com/android/toolbox/apis/media.html ?
====================
| Java: | Playing Media via URL
Uri myUrl = Uri.parse("http://myserver.com/link/to/my.mp3");
Intent intent = new Intent(Intent.VIEW_ACTION, myUrl);
intent.setType("audio/*");
startActivity(intent); |
====================
i try it, but it failed in startActivity(intent); ?
thank you very much !

Hello fisherman,
your secodn approch did not work, because 127.0.0.1 is the internal IP of the emulator. (Remember its a seperate linux-machine within your desktop pc).

I'm actually having the same problem when I'm using an external URI..
When I use the R.raw.<id> it works fine, but when I use the URI it says it starts playing when I use setDataSource but it actually does not...
My external URI is (works when I open it in a browser):
http://192.168.1.127:8080/androidService-1.0/cnet_podcast110607.mp3
I do have a SDCard emulated, since it asked for it while accessing the browser.
I think none of this is the problem tough, because I get an error with a view if I use the .create(Context, URI) method, it is attached.
Anyone knows this error or how to handle this?
CODE:
| Java: | public void onClick(View arg0) {
Log.d("MP", "ONCLICK");
myPD = ProgressDialog.show(Mediaplayback.this,
"Please wait...", "Loading the media file...", true);
new Thread() {
public void run() {
try {
Log.d("MP", "STARTING");
mp = MediaPlayer.create(Mediaplayback.this, myURL);
mp.start();
Log.d("MP", "STARTED");
} catch (Exception e) {
}
myPD.dismiss();
}
}.start();

Fixed View error!
Still not hearing sound.. I think the file needs to be downloaded to a local file first?
Needed to run myPD.dismiss() on the ui thread...
new code
| Java: | public void onClick(View arg0) {
Log.d("MP", "ONCLICK");
myPD = ProgressDialog.show(Mediaplayback.this,
"Please wait...", "Loading the media file...", true);
new Thread() {
public void run() {
try {
Log.d("MP", "STARTING");
mp = MediaPlayer.create(Mediaplayback.this, myURL);
mp.start();
Log.d("MP", "STARTED");
} catch (Exception e) {
}
runOnUIThread(new Runnable() {
public void run() {
try {
myPD.dismiss();
} catch (Exception e) {
}
}
});
}
}.start();

Hello Jesmiatka,
yes, downloading to local storage is what I normally done.
I have also seen that with some web-video-viewers.

|

hi, plusminus
thanks for your reply. i have another question about MediaPlayer, in
http://code.google.com/android/reference/android/media/MediaPlayer.html, it mention that
The MediaPlayer class is used for playing audio and video files and streams. but play mp3 file or 3gp file from url
seems to download the file and then play file, and it doest not play through streaming ?
can i play streaming audio, like "mms://streaming.books.com.tw/audio/6/0020095626_01_01.mp3".
Could you please give me some information about the media streaming that android support ?
Or whether the android m5 sdk currently only support playing from the local file , not streaming ?
thank you very much!

Hi everyone,
The original tutorial does not work for me either - (using the m5 release). It either WILL play an mp3 but only for a fraction of a second, or it won't play the mp3 at all (they are all less than 1mb in size).
The second solution does work, I pushed the mp3s manually into the emulator using DDMS and at least I can reliably play something now with:
MediaPlayer mp = new MediaPlayer();
mp.setDataSource("tmp/test.mp3");
mp.prepareAsync();
mp.start();
My question is, shouldn't I put the mp3 files in my application's own data folder? I cannot find it through DDMS. Also, how will others need to load these mp3 files? Do I need to tell friends to take all these external mp3s and do the same push command?
I wish the original method would work with the mp3 just in your eclipse resource folder, then it would be much easier. Anyone know why it doesn't work? Yet another android bug?
Thanks,
Mark

// i.e. react on the end of the music-file:

Hi,
Thanks for your post. For whatever reason, my onBuffering() handler never reaches 100%. This is the code I'm using now:
| Java: |
public class SoundPlayer
{
protected static boolean m_bSoundOn = true;
/** Turn sound on/off. */
public void setSoundOn(boolean bOn) {
m_bSoundOn = bOn;
}
protected static ArrayList<String> m_PlayQueue = new ArrayList<String>();
protected static boolean m_bPlayingSound = false;
/** Play an mp3 file. */
public static void playSoundBlocking(Context context,
String strFileName)
{
if (!m_bSoundOn) {
return;
}
if (m_bPlayingSound) {
return;
}
m_bPlayingSound = true;
try {
MediaPlayer mp = new MediaPlayer();
mp.setDataSource("data/data/files/" + strFileName);
if (mp != null){
mp.setOnPreparedListener(new
MediaPlayer.OnPreparedListener(){
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
mp.setOnCompletionListener(new
MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
m_bPlayingSound = false;
}
});
mp.setOnErrorListener(new
MediaPlayer.OnErrorListener() {
public void onError(MediaPlayer mp, int what, int extra) {
m_bPlayingSound = false;
}
});
mp.prepareAsync();
}
}
catch (IOException e ) {
context.showAlert("Error", 0, "Error playing mp3: [" + e.getMessage() + "].", "OK", true);
}
}
}
|
My OnCompletionListener() never seems to get called either. I'm not quite sure what's going on here. At least with the above code, the mp3s are played - its just that the app will randomly crash after playing a few mp3 clips.
Thanks for any pointers,
Mark

setOnBufferingUpdateListener will be called when playing online music(http://...........XXXX.mp3), if playing local music, setOnBuffering UpdateListener will not be called and I've only listened 500K online music and it stoped.

combine OnCompletionListener() with OnBufferingUpdateListener() when playing online music

Ok, I understand now that buffering is only for online media.
I'm trying to just play a local file. This is what my class to play mp3s looks like:
| Java: |
public class SoundPlayer
{
protected static boolean m_bSoundOn = true;
/** Turn sound on/off. */
public void setSoundOn(boolean bOn) {
m_bSoundOn = bOn;
}
protected static boolean m_bPlayingSound = false;
/** Play an mp3 file. */
public static void playSoundBlocking(Context context,
String strFileName)
{
if (!m_bSoundOn) {
return;
}
if (m_bPlayingSound) {
return;
}
m_bPlayingSound = true;
try {
MediaPlayer media = new MediaPlayer();
media.setDataSource("data/data/myapp/files/" + strFileName);
if (media != null){
media.setOnPreparedListener(new
MediaPlayer.OnPreparedListener(){
public void onPrepared(MediaPlayer mp) {
mp.start();
}
});
media.setOnCompletionListener(new
MediaPlayer.OnCompletionListener() {
public void onCompletion(MediaPlayer mp) {
//mp.release();
m_bPlayingSound = false;
}
});
media.setOnErrorListener(new
MediaPlayer.OnErrorListener() {
public void onError(MediaPlayer mp, int what, int extra) {
//mp.release();
m_bPlayingSound = false;
}
});
media.prepareAsync();
}
}
catch (IOException e ) {
context.showAlert("Error", 0, "Error playing mp3: [" + e.getMessage() + "].", "OK", true);
}
}
}
|
Again, it will play the files, but randomly the app will just crash after a few files are played (not consistent).
Is anyone actually playing mp3s consistently without error?
Thanks,
Mark

I've been reading through the thread that MediaPlayer.create(context, id) doesn't seem to work and that using MediaPlayer.setDataSource(string) works. My question is, can the setDataSource() read data from the .apx? If it does work what would the String to get to the /res/raw/my.mp3?
I have tried both methods and have been unable to succeed in playing a small .wav file.
