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 email: String? = "N/A",
var date: String = "",
var bike: Int = 0,
var profilepic: String = "",
/*var lat: Double = 0.0,
var longitude: Double = 0.0,
var zoom: Float = 0f,*/
var pickup: String = "",
var dropoff: String = "",
var price: Double = 20.0,
/*var amount: Int = 0*/
) : Parcelable
{
#Exclude
fun toMap(): Map<String, Any?> {
return mapOf(
// "id" to id,
"uid" to uid,
"name" to name,
"phoneNumber" to phoneNumber,
"email" to email,
"date" to date,
"bike" to bike,
"profilepic" to profilepic,

}

var lat: Double = 0.0,
var longitude: Double = 0.0,

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.

From Customadpate to adddetails i have to send the bitmap.

In onActivityResult you receive the picked image Uri, this can then be passed from one activity to the next by converting the Uri to a string then attaching it to the intent with .putExtra(), as seen below:
val intent = Intent(this, Activity::class.java)
intent.putExtra("Uri", imageUri)
startActivity(intent)
The information can then be received in the next activity by:
if (intent.getStringExtra("Uri") != null){
val uri = intent.getStringExtra("Uri")
}
The Uri will be in string form so all you have to do is convert it back to Uri form.
To convert bitmap to Uri , use the code below:
public Uri getImageUri(Context inContext, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
return Uri.parse(path);
}

Problem with notifyDatasetChanged in Base Adapter

I have a problem using the method notifyDataSetChanged for a BaseAdapter. I think i don't really understand who it works. I want to add a new Item to the list of view to show a loading screen while an image is uploading. Once the image is uploaded, I remove the item and call the method but im receiving and error and I don't understand why.

Thanks in advance.

Your are getting a null pointer exception.
// You have this class member
var adapter:TweetsAdapter? = null
override fun onCreate(savedInstanceState: Bundle?) {
// During on create, you are creating the adapter
// However, you are holding the adapter in a local variable
var adapter = TweetsAdapter(this, listofTweets)
}
fun uploadImage(bitmap:Bitmap){
// Then, here, when you try to read the adapter, you are reading
// the class member adapter (which is still null)
adapter!!.notifyDataSetChanged()
}
In order to fix the null pointer, update your onCreate method:
From:
var adapter = TweetsAdapter(this, listofTweets)
To:
this.adapter = TweetsAdapter(this, listofTweets)

Please refer this,
kotlin.TypeCastException: null cannot be cast to non-null type com.midsizemango.databasekotlin.Note
In your case try this:
val isArmed = dataSnapshot.value as? Boolean

Try this in onDataChange(..)
if(dataSnapshot.value != null) {
val isArmed = dataSnapshot.value as Boolean
toggleUIState(isArmed)
}
