how to retrieve the data from the onMetadataUpdated() while casting?

Question

i need to retrieve the some data(Custom Data) from the receiver app then only i can update my sender App UI in Mobile, I just passed the CustomData to receiver app while connecting to the Chromecast device which is working fine. i found the mRemoteMediaPlayer.setOnMetadataUpdatedListener but where how can i get the custom data from the receiver?.

Thanks in Advance

my Code part is

if (mRemoteMediaPlayer == null || !mApiClient.isConnected()) {
            Toast.makeText(this.ctx, "No Connection", Toast.LENGTH_LONG)
                    .show();
            return;
        }
        MediaMetadata mediaMetadata = new MediaMetadata(
                MediaMetadata.MEDIA_TYPE_MUSIC_TRACK);
        mediaMetadata.putString(MediaMetadata.KEY_ALBUM_ARTIST, ""
                + singers.getText().toString());
        mediaMetadata.putString(mediaMetadata.KEY_ALBUM_TITLE, ""
                + songTitle.getText().toString());
        mediaMetadata
                .addImage(new WebImage(Uri.parse(cdImgurlList.get(0))));

MediaInfo mediaInfo = new MediaInfo.Builder(songUrl)
                .setContentType("audio/mp3")
                .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
                .setCustomData(customjsonArrayWrapper)    //here pass the customData to the receiver.
                .setMetadata(mediaMetadata).build();
        mRemoteMediaPlayer
                .load(mApiClient, mediaInfo, true)
                .setResultCallback(
                        new ResultCallback<RemoteMediaPlayer.MediaChannelResult>() {

                            @Override
                            public void onResult(MediaChannelResult result) {
                                if (result.getStatus().isSuccess()) {
                                    Log.d(TAG, "Media loaded Successfully"
                                            + result.getStatus());
                                    Toast.makeText(
                                            RaagaActivity.this,
                                            "Media Channel loaded Successfully"
                                                    + result.getStatus(),
                                            Toast.LENGTH_SHORT).show();
                                    // Update the UI While chrome casting
                                    UpdateUIControlsinCasting();

                                } else {
                                    Log.d(TAG,
                                            "Media loaded Not Successfully"
                                                    + result.getStatus());
                                    Toast.makeText(
                                            RaagaActivity.this,
                                            "Media Channel not loaded Successfully"
                                                    + result.getStatus(),
                                            Toast.LENGTH_SHORT).show();
                                }
                            }
                        });

    } catch (IllegalStateException e) {
        String err = (e.getMessage()==null)?"IllegalStateException":e.getMessage();
        Log.e(TAG, err);
    } catch (Exception e) {
        // TODO: handle exception
        String err = (e.getMessage()==null)?"Exception":e.getMessage();
        Log.e(TAG, err);

If you want to retrieve the custom data when metadata updates, try the following: when onMetadataUpdated() of OnMetadataUpdateListener is called, get the MediaInfo by calling mediaInfo = mRemoteMediaPlayer.getMediaInfo() and then get the custom data via mediaIfo.getCustomData().
