To fetch the profile details, we need to create a function named getUser() in which we will call getUserById() from the Profile services. In return, it will provide the user details, or if there is an error, it will show the error message. Here is the code of the getUserById() function:

private fun getUser(){
        APIClient.profileAPICall(username,password)
            .getUserById(PrefUtils.getUsernameID(this)!!)
            .subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe({
                    myUser ->

                usernamePro.text = myUser.username
                profileFullNamePro.text = "${myUser.firstName} ${myUser.lastName}"
                emailPro.text = myUser.email
                contactNumberPro.text = myUser.contactNumber
                countryPro.text = myUser.country
            },{
                    error ->
                UtilMethods.hideLoading()
                Log.wtf("******", error.message.toString())
            })
    }
