App crash on first launch without internet

#1


source: https://github.com/riwu/synergy-lab-time-estimation/tree/master/client/android

If I install the app from Google Play and turn off internet connection before opening for the first time, the app crashes when opened.
The app is able to run normally with internet connection.

Debugged it adb logcat, crash log as follow:

There were no build warnings but Android Studio gave a warning about https://stackoverflow.com/questions/42374151/all-com-android-support-libraries-must-use-the-exact-same-version-specification though i doubt that’s the cause of crash since it works with internet connection.
