IllegalArgumentException: Cannot add a null child view to a ViewGroup

[KestasVenslauskas]

There is ongoing crash for the past year that has not been looked at... It's from crashlytics report. And I don't know how to reproduce this. This is comming from various devices.

Fatal Exception: java.lang.IllegalArgumentException: Cannot add a null child view to a ViewGroup

Someone could identify the root cause ?

Hi @KestasVenslauskas

Is this still an issue in the latest versions?
