Answer 1

This works well!

TrackGroupArray trackGroups = mappedTrackInfo.getTrackGroups(rendererIndex);   

TrackSelectionArray currentTrackGroups = player.getCurrentTrackSelections();
TrackSelection currentTrackSelection = currentTrackGroups.get(rendererIndex);


    for (int groupIndex = 0; groupIndex < trackGroups.length; groupIndex++) {

        TrackGroup group = trackGroups.get(groupIndex);

        for (int trackIndex = 0; trackIndex < group.length; trackIndex++) {
            Format trackFormat = group.getFormat(trackIndex);


            if(currentTrackSelection!=null && currentTrackSelection.getSelectedFormat()==trackFormat){
                //THIS ONE IS SELECTED
            }




        }
    }

rendererIndex is 0 for Video, 1 for Audio and 2 for Subtitles/Text
