In microg self-check page, all checks is passed. How can I solve this problem?

Start with the Logcat failure and the call at BasicMapDemoActivity.java:36, then inspect how SupportMapFragment is initialized in the reported app. Reproduce the blank map with the stated microG self-check results and determine whether the issue is in microG's maps-module loading or the app's setup; done requires a confirmed cause and reproducible resolution.
