Hello,

I was using **sample** native Android application from **Zoom Contact Center SDK** , versions **3.8.0.387** and **3.9.0.394**. The app crashes when trying to connect to the Contact Center.

Can you please assist me with solving the issue?

My steps:

1. Launch the app.

2. Invoke the following code:

3. Page appears with a Loading indicator.

4. Popup appears.

5. Enter name.

6. Press “Next”.

7. Popup closes.

8. App crashes within a few seconds.
