updating storage with the use of io fotoapparat library | Kotlin

I make a mobile application using the "io fotoapparat" library and I want to create a document with a random id and in the document in the id field, add the document id, the photo we will take was updated in the firebase store and in the previously made about the same id in the receipt collection when taking a photo
link from which I took "io fotoapparat"
EDIT
add to firestore document
binding.button.setOnClickListener {
// Inflate the layout for this fragment
val biedronka = "biedronka"
val price = "20"
val img = " "
val identificator = " "
val from = biedronka
val value = price
val image = img
val idd = identificator
val db = Firebase.firestore
val data = hashMapOf(
"from" to from,
"value" to value,
"image" to image,
"id" to idd
)
db.collection("receipts")
.add(data)
.addOnSuccessListener { documentReference ->
Log.d(SCAN_DEBUG, "DocumentSnapshot written with ID: ${documentReference.id}")
db.collection("receipts")
.document(documentReference.id)
.update("id", documentReference.id)
.addOnSuccessListener {
}
}
.addOnFailureListener { e ->
Log.w(SCAN_DEBUG, "Error adding document", e)
}
}
2 add to storage and to document (doesnt work)

Firebase recyclerview images disappear after reload application

When I just added it, everything is fine, but when I restart the application, only textViews is displayed. There is an empty space instead of an imageView.
My recycler adapter:
class PersonAdapter(options: FirebaseRecyclerOptions<Outfit?>) :
FirebaseRecyclerAdapter<Outfit, personsViewHolder>(options) {
override fun onBindViewHolder(holder: personsViewHolder, position: Int, model: Outfit) {
holder.name.text = model.name
holder.brand.text = model.brand
holder.size.text = model.size
holder.comment.text = model.comment
holder.price.text = model.price
Picasso.get().load(model.imageUrl).into(holder.imageView) //Glide analog
}
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): personsViewHolder {
val view = LayoutInflater.from(parent.context)
.inflate(R.layout.recycler_item, parent, false)
return personsViewHolder(view)
}
class personsViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var name: TextView = itemView.findViewById(R.id.tv_name_value)
var brand: TextView = itemView.findViewById(R.id.tv_brand_value)
var size: TextView = itemView.findViewById(R.id.tv_size_value)
var comment: TextView = itemView.findViewById(R.id.tv_comment_value)
var price: TextView = itemView.findViewById(R.id.tv_price_value)
var imageView: ImageView = itemView.findViewById(R.id.imageView)
}
}

Logic at MainActivity:

// Connecting object of required Adapter class to the Adapter class itself

// Connecting Adapter class with the Recycler view*/
recyclerView.adapter = adapter
swipeRefreshLayout.setOnRefreshListener(this)

If you access the id of the user with the following code val reference = FirebaseDatabase.getInstance().reference.child("Users").child(userIdVisit) and then you try to get the data as a model Chat you can not do that, instead try FirebaseDatabase.getInstance().reference.child("Users").This way you'll be able to get your data as model Chat but it won't be the id you want, also if at the node "Users" you have more users then you'll obtain all the users info using the model Chat
If you need the information for the userIdVisit then you can you do the following
snapshot.child("userInfo1").getValue();
snapshot.child("userInfo2").getValue();
This is the sample for java, you should adapt it for kotlin, I'm sorry for not providing the sample in kotlin but I'm not familiar with it

Kotlin - Firebase - Save Uri to user's folder images keeps saving wrong Uri

I am not sure how to set my private fun share() to upload correct URL to User's "images" folder
and here is my CameraHelper.kt
class CameraHelper(private val activity: Activity){
var imageUri: Uri? = null
val REQUEST_CODE = 1
private val simpleDateFormat = SimpleDateFormat(
"yyyyMMdd_HHmmss",
Locale.US
)
fun takeCameraPicture() {
val intent =
Intent(MediaStore.ACTION_IMAGE_CAPTURE)
if (intent.resolveActivity(activity.packageManager) != null) {
val imageFile = createImageFile()
imageUri = FileProvider.getUriForFile(
activity,
"com.example.homeactivity.fileprovider",
imageFile
)
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri)
activity.startActivityForResult(intent, REQUEST_CODE)
}
}
private fun createImageFile(): File {
val storageDir: File? = activity.getExternalFilesDir(
Environment.DIRECTORY_PICTURES
)
return File.createTempFile(
"JPEG_${simpleDateFormat.format(Date())}_",
".jpg",
storageDir
)
}
}

You're not using the result from putFile(imageUri) correctly. You have:
putFile(imageUri).addOnCompleteListener {
if (it.isSuccessful){
mFirebase.database.child("images").child(uid).push()
.setValue(it.toString())
That it.toString() is not the URL. it is the UploadTask object returned by putFile(). You can't just turn that into a string - it's a Task that you need to observe to get the result.
You seem to be fetching a download URL correctly in uploadUserPhoto using downloadUrl to fetch the URL to write. You're going to have to do it that way instead.
See also the documentation and this question.

I managed to solve it.
In case anyone needs it, here is working function share():
private fun share(){
val imageUri = mCamera.imageUri
if (imageUri != null){
val uid = mFirebase.auth.currentUser!!.uid
val uTask = mFirebase.storage.child("users").child(uid).child("images").child(imageUri.lastPathSegment!!).putFile(imageUri)
mFirebase.storage.child("users").child(uid).child("images").child(imageUri.lastPathSegment!!).putFile(imageUri)
.addOnCompleteListener {
if (it.isSuccessful) {
uTask.continueWithTask { _ ->
mFirebase.storage.child("users").child(uid).child("images")
.child(imageUri.lastPathSegment!!).downloadUrl
}.addOnCompleteListener {
if (it.isSuccessful && it.result != null)
mFirebase.database.child("images").child(uid).push()
.setValue(it.result.toString())
.addOnCompleteListener {
if (it.isSuccessful) {
startActivity(
Intent(
this,
ProfileActivity::class.java
)
)
finish()
} else {
showToast(it.exception!!.message!!)
}
}
}
} else {
showToast(it.exception!!.message!!)

Getting a class not found exception along with cannot decode stream exception while trying to retrieve images

I am getting a class not found exception when trying to click an image from the camera or while fetching it from the directory. The code is in kotlin and has been given below.
This is the class which implements the functionality to capture an image or picks them from the gallery.
The methods _openCamera() and openFileSelector() are implemented.
The main motive was to capture the images and upload them in the server but the implemented methods doesn't give the proper results.

The error shows when I try to click an image or fetch from the library.
The provider path used is given below:
<paths xmlns:android="http://schemas.android.com/apk/res/android">
<external-path
name="external_files"
path="." />
</paths>
I have tried changing the path to "/" but it didn't work. The error wasn't showing earlier but the error exists now.
Here is the snapshot of the logs.
All suggestions are accepted. Thanks in advance.
