Webview using multiple MediaPlayer objects via @javascript interface in parallel?

Question

JavaScript

Hello :)
There is a small interface between Webview and AndroidSDK

public class AudioInterface {
        Context mContext;

        AudioInterface(Context c) {
            mContext = c;
        }

        //Play an audio file from the webpage
        @JavascriptInterface
        public void playAudio(String name, String src) { //String aud - file name passed
            //from the JavaScript function
            final MediaPlayer mp;
            try {
                AssetFileDescriptor fileDescriptor = mContext.getAssets().openFd(src);
                mp = new MediaPlayer();
                mp.setDataSource(fileDescriptor.getFileDescriptor(),fileDescriptor.getStartOffset(),fileDescriptor.getLength());
                fileDescriptor.close();
                mp.prepare();
                mp.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
                    @Override
                    public void onPrepared(MediaPlayer mp) {
                        mp.start();
                    }
                });
                mp.setOnCompletionListener(new MediaPlayer.OnCompletionListener() {
                    @Override
                    public void onCompletion(MediaPlayer mp) {
                        mp.release();
                    }
                });
            } 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();
            }
        }
    }

And its call via Javascript
playSound("play_1","blabla.mp3");
It is necessary not only to lose, but also to be able to lose several, and even in parallel, besides being able to control (start, stop, delete).
That is, it is probably necessary to create an object with a name from String name
playAudio(String name, String src)
here
final MediaPlayer mp;
and further.
Or maybe MediaPlayer has some built-in methods for this.
Help super-programmers, a.
Thanks in advance!
