Hi @conrad.s.j.gomes, thanks for using the devforum.

The `DeadObjectException` you are seeing is due to the process hosting an object no longer existing by the time the object is referenced. This points towards an issue with the Android implementation being used on the device prematurely killing processes that are still being used by the SDK.

Thanks!

Hi @jon.zoom,

Is the DeadObjectException causing the FATAL EXCEPTION due to  
` java.lang.RuntimeException: Unable to create service com.zipow.videobox.share.ScreenShareServiceForSDK: java.lang.IllegalArgumentException: null notification`

I see some dependency on Android Keystore. Is it required for Zoom native SDK to run properly?

Thanks

Hi @conrad.s.j.gomes,

The Android Keystore is part of the Android implementation already on your device. There should not be any action required on your end for an app to utilize this.

The issue seems to stem from a process being killed unexpectedly on your device.

Thanks!

Like hardware incompatibility, a slow or overloaded system can cause zoom crashing. Because the app requires a significant portion of your device’s memory, opening multiple applications and Windows can affect the way it runs.

Hi @jerir.byrd,

This forum is only meant to discuss the Meeting SDK directly, so please keep the content limited to that topic. If you would like to discuss the Zoom client, you can use the [Zoom Community](https://community.zoom.com/). 🙂

Thanks!
