Getting "UnknownHost Exception: No address associated with hostname" while accessing Splunk REST API in android device

[deepaksplunk201]

Hi,
I am trying to access Splunk REST API in android device. The services/auth/login API gives "UnknownHost Exception: ... No address associated with hostname". The respective host:port of Splunk Enterprise, I am able to access in Android emulator through Android Studio but for android device, it gives exception.

Please let me know the way to access the Splunk enterprise host:port into Android device.

Thanks,
