MediaPlayer isPlaying: called in state MEDIA_PLAYER_STATE_ERROR

Question

I am working on an app using Cordova. In this app I have 30 pages and it should play the sound on every swipe. It works fine until about 20 pages and then I start getting this error

MEDIA_PLAYER_STATE_ERROR

Based on my search on this forum I believe it's coz of the media not being released but the examples I have seen are java based. I am having hard time figuring out where to call release Media.

Would appreciate any help.Thank you.

Below is my current code

function playAudio(src) {
        // Create Media object from src
    try{
      my_media = new Media(src,onSuccess,onError,status_change);

                // Play audio
                my_media.play();

                // Update my_media position every second
                if (mediaTimer == null) {
                    mediaTimer = setInterval(function() {
                        // get my_media position
                        my_media.getCurrentPosition(
                            // success callback
                            function(position) {
                                if (position > -1) {
                                    setAudioPosition((position) + " sec");
                                }
                            },
                            // error callback
                            function(e) {
                                console.log("Error getting pos=" + e);
                                setAudioPosition("Error: " + e);
                            }
                        );
                    }, 1000);
                }

    } catch (e){
    console.log("In catch");
         releaseMedia();
    }
   }


    function pauseAudio() {
        if (my_media) {
            my_media.pause();
        }
    }

    // Stop audio
    //
    function stopAudio() {
        if (my_media) {
            my_media.stop();
        }
        clearInterval(mediaTimer);
        mediaTimer = null;
    }
    // onSuccess Callback
    //
    function onSuccess() {
        console.log("playAudio():Audio Success");
    }

    // onError Callback
    //
    function onError(error) {
        console.log('code: '    + error.code    + '\n' +
              'message: ' + error.message + '\n');
              releaseMedia();
    }
    function releaseMedia(){
         if (my_media) {
                    my_media.release();
         }
         clearInterval(mediaTimer);
         mediaTimer = null;
    }

function status_change(code) {
    switch (code) {
    case Media.MEDIA_STOPPED :  console.log("stopped"); break;
    case Media.MEDIA_STARTING : console.log("starting"); break;
    case Media.MEDIA_RUNNING : console.log("running"); break;
    case Media.MEDIA_ERROR: console.log("error");break;
    }

}

Adding below code before creating Media in playAudio(src) fixed the issue.

if(my_media != null){
         releaseMedia();
 }
