MediaPlayer : I'm getting mad !

Hello !

I'm getting mad trying to make my application play a sound !...

I'm developping under Eclipse, with SDK 1.5. I put my mp3 file into the raw folder.

And put this function in my main activity:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

        public void playMusic() {
 
                try {
 
                        MediaPlayer mp = new MediaPlayer();
 
                        mp.create(this, R.raw.mynotif);
 
                        mp.start();
 
                        Toast.makeText(this, "Launched ?",Toast.LENGTH_SHORT).show();
 
                        mp.release();
 
                } catch (Exception e) {
 
                        Toast.makeText(this, "Exception: " + e.getMessage(),Toast.LENGTH_SHORT).show();
 
                }
 
        }
 
Parsed in 0.032 seconds,  using GeSHi 1.0.8.4

The activity only display a view, and launch the playMusic function.

The result is only a TOAST saying "Launched ?" : taht means there is no exception but ... I CANNOT HEAR ANYTHING !

I thought it was an emulator setting issue, but the application "Music" can play music and I can hear it...

Any idea ??

Tahnk you very much for your precious help !!!

Nek.

Additional info

If I add the method

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

mp.prepare();
Parsed in 0.030 seconds,  using GeSHi 1.0.8.4

it raises a exception, saying the mp is NULL...

If it helps...

...
MediaPlayer mp= MediaPlayer.create(this,R.raw.mynotif)
mp.start();
....

and you should call the release method, when you are done with the sound.

Thanks for the answer, but I found...

I changed three things: the declaration of the MediaPlayer, the context, and the RELEASE...

I think the release is launched too "early", and stop the sound...

Here is the working code :

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

 
        MediaPlayer mp; 
 
        public void playMusic(Context theContext) {
 
                try {
 
                mp = new MediaPlayer(); 
 
                mp = MediaPlayer.create(theContext, R.raw.mynotif); 
 
                mp.start();                     
 
                        Toast.makeText(this, "Launched ?",Toast.LENGTH_SHORT).show();
 
                        mp.release();
 
                } catch (Exception e) {
 
                        Toast.makeText(this, "Exception: " + e.getMessage(),Toast.LENGTH_SHORT).show();
 
                }
 
        }

you can set a listener to release the resources when you are done,

something like that:

Syntax: [ Download ] [ Hide ]

Using java Syntax Highlighting

mp.setOnCompletionListener(new OnCompletionListener(){
 
mp.release();
 
});
