String duration = 
mmr.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
mmr.release();

method to get internal storage audio file duration in seconds

public String gettotaltimestorage(String filePath) {
    // load data file
    Log.d("time=================>","time=================>");
    MediaMetadataRetriever metaRetriever = new MediaMetadataRetriever();
    metaRetriever.setDataSource(YourACTIVITY.this, Uri.parse(filePath));
    Log.d("time=================>","time=================>");
    String out = "";
    // get mp3 info

    // convert duration to minute:seconds
    String duration =
            metaRetriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_DURATION);
    Log.d("time=================>", duration);
    long dur = Long.parseLong(duration);
    String seconds = String.valueOf((dur % 60000) / 1000);
    Log.d("seconds===========>", seconds);
    // close object
    metaRetriever.release();
    return  seconds;
