Way to go, Google. Yes, Android Lollipop is no longer officially supported, but it would be nice if updating certain Google libraries would not lead to Lollipop devices crashing at app launch. First the crash was caused by one 3rd-party library missing from the APK, but we got rid off that by updating the library as well as the other 3rd-party libraries that depended on it. Now the app crashes when it tries to load an Android architecture library (lifecycle).
Some days I just want to go home and weep. Today seems to be one such a day.
