We have recently updated our Zoom SDK to v5.4.3.613. In this version, we are getting a Crashlytics error on Firebase which says

Fatal Exception: java.lang.NullPointerException
   Attempt to invoke interface method 'boolean android.content.SharedPreferences.getBoolean(java.lang.String, boolean)' on a null object reference
  com.zipow.videobox.util.PreferenceUtil.readBooleanValue (

Hi @pavan.careers5208, thanks for the post.

Sorry to hear you’re seeing a crash on the latest SDK version. Can you please let me know how frequently your users are seeing this crash? Have you been able to reproduce it at all?


@ jon.lieblich
The top two issues on our list are these zoom related crashes. We are not able to reproduce this issue. But there are users who are seeing this crash. These crashes are seen only on latest SDK not before
For frequency and users affected please check the image attached.

Hi @pavan.careers5208,

Thank you for the additional information. We will investigate this and let you know as soon as we have additional information. In the meantime, please let me know if you identify steps to reproduce this crash, as it may significantly improve the amount of time it takes for us to identify a fix.
