The method in question is:

    private static Locale getSimBasedLocale(@NonNull Context context) {
        final TelephonyManager tm =
                (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);
        final String countryIso = tm != null ? tm.getSimCountryIso() : null;
        return TextUtils.isEmpty(countryIso) ? null : new Locale("", countryIso);
    }

Line 1342 is context.getSystemService(....) so maybe we are passing a null Context into this method from somewhere?

The fix for this issue has been released in v2.1.0.
