deviceId() is null after call initialize()

[viglis]

SDK Version and configuration details

v1.20.7

Expected Behavior

deviceId shouldn't be null or we need to have a callback to know when amplitude is initialized correctly.

Current Behavior

Hi. For integration for other analytics tool(ex. airbridge) I need to know amplitude deviceId. And it is null after Amplitude.initialize(...) call. But If I fetch deviceId after like a second after initialize call then it is non null.

Possible Solution

I don't know how long to take deviceId.

Steps to Reproduce

Amplitude(Configuration)
client.getDeviceId() == null

Environment

• Galaxy S23 FE(OS15)
