Apps Getting different Android IDs for same device. Why?

[Asifkhan1104]

I am getting different Android IDs for same device for 2 apps in spite of they are being signed with same keystore. This problem is occurring only in Android Oreo OS. Can anyone help me why there are 2 different Android IDS generated?

The method i am using for Android Id -

int deviceId = Settings.Secure.getString(pContext.getContentResolver(), Settings.Secure.ANDROID_ID)

Doesn't look like it's too reliable.
I've never used it myself, but there's some more information here
