new version of our app has launched yesterday using your library and a lot of crashes happened really fast here is the crash 

Fatal Exception: kotlin.KotlinNullPointerException
       at com.opensooq.pluto.PlutoIndicator.getShouldDrawCount + 91(PlutoIndicator.kt:91)
       at com.opensooq.pluto.PlutoIndicator.redraw + 403(PlutoIndicator.kt:403)

       at com.opensooq.pluto.base.PlutoAdapter.clear + 47(PlutoAdapter.kt:47)

we have set app:indicator_visibility="false" //this line didn't make the indicators disappear on its own so also onCreate we have set plutoView.setIndicatorVisibility(false);

any help would be appreciated thanks

@Ramzi-Alqrainy @tamtom turns out that this is happening because of configuration changes and the activity being recreated what do you suggest for handling this ? I thought that recreating the activity would create a new instance but apparently the old instance remains with null recyclerView ? can you help me please ?

@amjadmasri fixed in 1.6
