cgeo: (all) Authorization does not work anymore

Describe the bug: Authorization does not work anymore

To Reproduce: try to login/connect to one of the platforms or services

Actual behavior/state after performing these steps: The login breaks or hangs or c:geo craches (e.g. geocaching.com, oc.de -> appcrash, geokrety.org -> hang - see screenshot)

Expected behavior/state after performing these steps: login success

Version of c:geo used: current master

Is the problem reproducible: Yes

Screenshots:

System information: Samsung S6

Additional information Maybe a problem with the lambda code form in the *AuthorizationActivity classes?

Stack trace when reattaching to the hanging app:
