How to set the visibility GONE after the download was successful, and visibility still VISIBLE if download was unsuccessful?

I am making a studymaterial app, where i want to add a functionality where - when a user download a particular chapter from recyclerview and after the successful download of that item the Download button visivity should make GONE of that item at that time.
I have implemented a method to do thisd but it only works when user finish the activity and come back again on that activity then the download button automatic not showing, but i want to implement at that point of time when user download something.
Here is my DownloadHandler.kt class
package com.tworoot2.class9thhistoryncert.downloadHandler
import android.app.AlertDialog
import android.app.ProgressDialog
import android.content.Context
import android.content.Intent
import android.widget.Toast
import com.downloader.*

import java.io.File
import com.tworoot2.class9thhistoryncert.R
class DownloadHandler {
lateinit var alertDialog: AlertDialog.Builder
lateinit var failed: AlertDialog.Builder
var progressDialog: ProgressDialog? = null
var fileDestination: File? = null
var down: Boolean = false
fun downloadFile(url: String?, fileName: String, context: Context, filePath: File): Boolean {
progressDialog = ProgressDialog(context)
progressDialog!!.setMessage("Downloading....")
progressDialog!!.setCancelable(false)
progressDialog!!.max = 100
progressDialog!!.setProgressStyle(ProgressDialog.STYLE_SPINNER)
progressDialog!!.show()
alertDialog = AlertDialog.Builder(context)
alertDialog.setTitle("Downloaded successfully")
alertDialog.setMessage("$fileName is downloaded successfully")
alertDialog.setIcon(R.drawable.check)
alertDialog.setPositiveButton(
"Open"
) { _, i ->
val intent = Intent(context, DownloadedFiles::class.java)
context.startActivity(intent)
}
failed = AlertDialog.Builder(context)
failed.setTitle("Downloading failed")
failed.setMessage("Your file is not downloaded successfully")
failed.setIcon(R.drawable.failed)
PRDownloader.download(url, filePath.path, fileName)
.build()
.setOnStartOrResumeListener { }
.setOnPauseListener { }
.setOnCancelListener { }
.setOnProgressListener { progress ->
val per = progress.currentBytes * 100 / progress.totalBytes
progressDialog!!.setMessage("Downloading : $per %")
}
.start(object : OnDownloadListener {
override fun onDownloadComplete() {
down = true
Toast.makeText(context, "Download completed ", Toast.LENGTH_SHORT).show()
progressDialog!!.dismiss()

Maybe you want to use LiveData to handle realtime update UI for your case. After download thread run completed, let observer call update item in recyclerview.
Hope it help!

Profile Pic not displaying on Card View in Andorid Studio Kotlin

I am trying to get a users profile pic to be displayed beside their booking on a card in my recyclerview. The profile pic is displaying in my nav drawer, a default one for non-google users, or the profile pic of the Google user. However imageUri appears empty when I call it and the images are not being stored in my firebase storage bucket. I have linked my firebase and implemented the relevant SDK.
Here is my model.
#Parcelize
data class BookModel(
// var id : Long = 0,
var uid: String? = "",
var name: String = "N/A",
var phoneNumber: String = "N/A",

var bike: Int = 0,
var profilepic: String = "",
/*var lat: Double = 0.0,
var longitude: Double = 0.0,

.centerCrop()
.into(binding.imageIcon)
//
// binding.name.text = booking.name
// binding.phoneNumber.text = booking.phoneNumber
// binding.date.text = booking.date
binding.root.setOnClickListener { listener.onBookingClick(booking) }
// binding.buttonDelete.setOnClickListener { listener.onDeleteBooking(booking) }
// binding.buttonUpdate.setOnClickListener { listener.onUpdateBooking(booking) }
binding.executePendingBindings()
/* binding.imageIcon.setImageResource(R.mipmap.ic_launcher_round)*/
}
}
}
I believe the problem stems from the (FirebaseImageManager.imageUri.value.toString()) on my BookAdapter, as if I run a Timber.I statement it doesn't return anything at all. If I run Timber.i(FirebaseImageManager.imageUri.value.toString()+ "test"), it only returns test.

Apologies if I wasn't clear enough, I am a novice.

I figured it out, I had to modify my rules on the firebase storage.

Any clue about how to resolve and debug?
this is my env:
Mesibo AP = 2.7.0
Build tools = 29.0.0
compile SDK versions = 30
appid = com.project.bucynapp
Thanks!

Have you tried the custom scripts or mesibo webhook to debug the issue? Have you referred to the Troubleshooting section in the mesibo push-notification document?
https://mesibo.com/documentation/api/push-notifications/
Unless you post logs and steps you have taken, we have no clue what is happening.

How to save a new user if the entered details are new and load an existing user if the credentials exist using an SQLitedatabase?

I would like to create and store new users also update the existing users in the following code
What code needs to be added to strore new users in a SQLitedatabase
I have a sqllitehelper class
which has adduser,updateuser,and readuser methods
From what i understand ,the signinfragment activity stores the instance of the logged in user and
if the instance exists then its loaded.When we logout we basically have to make a new user and we login
i would like to create,store,update users using an SQLite database.
