crash with java.lang.NullPointerException at ReverseGeocodeObservable.java:40

[Redbu11dev]

Hello, I am using this library (implementation 'pl.charmas.android:android-reactive-location2:2.1@aar') and it keeps crashing on some devices :(

Can anyone help me to prevent this from crashing?

From the source code I can see, that it's happening when creating an instance of Geocoder in observables/geocode/ReverseGeocodeObservable.java:

"Geocoder geocoder = new Geocoder(ctx, locale);"

Google play crash report:
