I had a wee go at this a couple of days ago (no charge P38). When you load a gpx into google earth desktop it converts it to a kmz and you can save it to My Places. For some crazy reason Google remove the ability to access My Places from Google Earth on Android and iOS so the only way to do it is to share it via google drive or one drive as the posts above say. Also google earth Android won't convert gpx to kmz so they have to be in the right format. img is a unique Garman format so that doesn't work either.
