map fragment shows blank when app resumes from background to front. GL thread crash

问题

I compiled a HERE tutorial app, "basic map solution", and installed it on Motorola XT1565(android 6.0.1). When I launch it, the map view can be shown, but if I move it to background and later bring it back to front, sometimes I see the map view is blank: no map content. I caught the following GL thread crash error in the log.

I am using HERE Android SDK 3.1.1, and I can not find same issue on Here official app from Google Playstore. So I wonder if this issue is related to EGL lib compatible issue or there are some bugs in Here SDK native lib?
