Question

i’m trying to use this code which i called from a button but it doesn’t work and when i see the LogCat window i found Media Player called in state 0, error (-38,0)

public void audioPlayer(String path, String fileName){

//set up MediaPlayer    
        MediaPlayer mp = new MediaPlayer();

        try {
            mp.setDataSource(HeyActivity.this, Uri.parse(path+"/"+fileName));
        } catch (IllegalArgumentException 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
            System.out.print("hey");
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

        mp.start();

    }

Try setting OnPreparedListener and call the start method within it. Like this:

MediaPlayer mp = new MediaPlayer();
mp.setOnPreparedListener( new OnPreparedListener() {

    public void onPrepared(MediaPlayer mp) {
        mp.start();
    }
}; 
);
