How to Get the Device's IMEI/ESN Programmatically in Android using Jetpack Compose?

Android applications many times require the unique identity of the user while developing applications. This unique identity is used to identify the user of the application. Many android apps use the IMEI number as the unique identity of each user. In this article, we will take a look at How to get Device IMEI and ESN Programmatically in android using Jetpack Compose. 

Important: From Android 10+, we can no longer access the IMEI number of an android device. This required the permission READ_PRIVILEGED_PHONE_STATE which is only accessible to system apps.
