After addOnSuccessListener() the app is redirected to other activity

In my app I have implemented image upload to firebase storage, after upload url of the image is stored in realtime database for future use. Everything is working perfectly except whenever the url of the image is stored in realtime database the app move towards the BottomNavigation. below is my code
Adapter Class from which the app is redirected towards the pictureTakingActivity
class PrintAdapter(val data:ArrayList<PrintModel>) : RecyclerView.Adapter<PrintAdapter.MyViewHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): MyViewHolder {
var view = LayoutInflater.from(parent.context).inflate(R.layout.single_row_home, parent, false)
return MyViewHolder(view)
}
override fun onBindViewHolder(holder: MyViewHolder, position: Int) {
holder.name.setText(data.get(position).name)
Picasso.get().load(data[position].image).into(holder.image)
Log.d("TAG", "The image is: " + data[position].catName)
var cat = data.get(position).catName
holder.itemView.setOnClickListener{
if (cat.equals("photo")){
val intent = Intent(it.context, PictureTakingActivity::class.java)
it.context.startActivity(intent)
}
}
}
override fun getItemCount(): Int {
return data.size
}
class MyViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
// Both of these can be used to find id

Adding user profile picture in Kotlin

I've recently started programming in Kotlin and cannot seem to add a profile picture to a user when registering it.
According to the code here, I can access to the gallery and retrieve the image information. The picture will appear on screen, but after registering the user the image url will not appear anywhere.
class RegisterUser : AppCompatActivity() {
private val database = FirebaseDatabase.getInstance()
private val auth: FirebaseAuth = FirebaseAuth.getInstance()
private val UserCreation = database.getReference("Usuarios")
private val pickImage = 100
private var imageUri: Uri? = null
lateinit var imageView: ImageView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_register_user)
Goback.setOnClickListener {
val Gobackou = Intent(this, MainActivity::class.java)
startActivity(Gobackou)
}
RegisterConfirm.setOnClickListener {
val SetUser = SetUser.text.toString()
val SetPass = setPass.text.toString()
val SetEmail = SetEmail.text.toString()
if (SetUser.isEmpty() && SetPass.isEmpty() && SetEmail.isEmpty()) {
Toast.makeText(this, "Faltan Campos", Toast.LENGTH_SHORT).show()
} else {
RegisterUserv2(SetEmail, SetPass, SetUser)
}
}
selectPP.setOnClickListener {
val intent = Intent(Intent.ACTION_PICK)
intent.type = "image/*"
startActivityForResult(intent, pickImage)
}
}
var selectedPhotoUri: Uri? = null
//guardar la foto de perfil
override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
super.onActivityResult(requestCode, resultCode, data)
if (resultCode == RESULT_OK && requestCode == pickImage) {
val selectedPhotoUri = data?.data
val bitmap = MediaStore.Images.Media.getBitmap(contentResolver, selectedPhotoUri)
val bitmapDrawable = BitmapDrawable(bitmap)
userimg.setBackgroundDrawable(bitmapDrawable)
}
}
private fun RegisterUserv2(email: String, password: String, user: String) {
auth.createUserWithEmailAndPassword(email, password).addOnCompleteListener(this) { task ->
if (task.isSuccessful) {
uploadimage()
UltrasaveUsuario(Usuarios(auth.currentUser!!.uid, user, password, email))
val Gobackou = Intent(this, MainActivity::class.java)
startActivity(Gobackou)
} else {
Toast.makeText(this, "Registro ERROR", Toast.LENGTH_LONG).show()
}
}
}
private fun UltrasaveUsuario(usuario: Usuarios) {
val mensajeFirebase = UserCreation.push()
usuario.id = mensajeFirebase.key ?: ""
mensajeFirebase.setValue(usuario)
}
private fun uploadimage(imageurl: String){
if (selectedPhotoUri == null) return
val filename = UUID.randomUUID().toString()
val ref = FirebaseStorage.getInstance().getReference("/images/$filename/")
ref.putFile(selectedPhotoUri!!)
.addOnSuccessListener {
ref.downloadUrl.addOnSuccessListener{
}
}
}
}

Since you are using firebase I will show you how to save firebase storage.
private fun uploadImage() {
if (mSelectedImageFileUri != null) {
val sRef: StorageReference = FirebaseStorage.getInstance().reference.child(
"users/ $uid/profile.jpg"
)
sRef.putFile(mSelectedImageFileUri!!)
.addOnSuccessListener { taskSnapshot ->
taskSnapshot.metadata!!.reference!!.downloadUrl
.addOnSuccessListener { url ->
}
}.addOnFailureListener {
//error
}
} else {
}
}
then you will take this picture using the user id to take .
firebase>storage to view the image
getImage
val sRef: StorageReference = FirebaseStorage.getInstance().reference.child(
"users/ $uid/profile.jpg"
)
sRef.downloadUrl.addOnSuccessListener {
Picasso.get().load(it).into(globalprofileImage)
}

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 {

RecyclerView list item does not show when entries are made to the Room database

I am trying to rewrite an existing app in Kotlin for the purpose of learning and getting used to the language. The app allows the user to enter and modify entries and each entry is hosted in a RecyclerView list with a custom list item. Although entries are successfully added to the database (confirming that with Toast messages), there isn't a list item present for the said entry.
This is my adapter:
class EntryAdapter : androidx.recyclerview.widget.ListAdapter<Entry, EntryAdapter.ViewHolder>(DIFF_CALLBACK){
private var listener: OnItemLongClickListener? = null
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ViewHolder {
val view = LayoutInflater.from(parent.context).inflate(R.layout.recyclerview_item, parent, false)
return ViewHolder(view)
}
override fun onBindViewHolder(holder: ViewHolder, position: Int){
val currentEntry = getItem(position)
holder.hint.text = currentEntry.hint
holder.username.text = currentEntry.username
holder.password.text = currentEntry.password
}
fun getEntryAt(position: Int): Entry{return getItem(position)}
inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView){
val username: TextView = itemView.findViewById(R.id.username_display)
val password: TextView = itemView.findViewById(R.id.password_display)
val hint: TextView = itemView.findViewById(R.id.hint_display)
init {
itemView.setOnLongClickListener{
val position = adapterPosition
if (listener != null && position != RecyclerView.NO_POSITION){listener!!.onItemLongClick(getItem(position))}
true
}
}
}
interface OnItemLongClickListener{fun onItemLongClick(entry: Entry)}
fun setOnItemLongClickListener(listener: OnItemLongClickListener){this.listener = listener}
companion object{
private val DIFF_CALLBACK = object : DiffUtil.ItemCallback<Entry>(){
override fun areItemsTheSame(oldItem: Entry, newItem: Entry): Boolean{return oldItem.id == newItem.id}
override fun areContentsTheSame(oldItem: Entry, newItem: Entry): Boolean{return oldItem.username == newItem.username && oldItem.hint == newItem.hint && oldItem.password == newItem.password}
}
}
}
This is my AddEditEntry.kt activity. The way it works is that when the user wishes to make an entry, he/she clicks on the FAB button which invokes this activity. This activity is where the user enters the entry and adds it to the database (and by extension, the RecyclerView) by clicking the saveEntry button:
class AddEditEntryActivity : AppCompatActivity() {

val intent = intent
if (intent.hasExtra(EXTRA_ID)) {

}
private fun generatedPassword(): String? {
var length = 0
val generatedString = StringBuilder()
val rand = Random()
val capitalLetters = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
val lowercaseLetters = "abcdefghijklmnopqrstuvwxyz"
val numbers = "0123456789"
val characters = "!##$%^&*()"
if (radio4!!.isChecked) {length = 4}
else if (radio8!!.isChecked) {length = 8}
else if (radio12!!.isChecked) {length = 12}
else if (radio16!!.isChecked) {length = 16}
var totalCharacters = ""
if (passwordABCD!!.isChecked) {totalCharacters += capitalLetters}
if (passwordabcd!!.isChecked) {totalCharacters += lowercaseLetters}
if (password0123!!.isChecked) {totalCharacters += numbers}
if (passwordSymbols!!.isChecked) {totalCharacters += characters}
if (!totalCharacters.trim { it <= ' ' }.isEmpty() && length > 0) {
for (i in 0 until length) {generatedString.append(totalCharacters[rand.nextInt(totalCharacters.length)])}
return generatedString.toString()
}
else {Toast.makeText(this, "Not a valid password!", Toast.LENGTH_SHORT).show()}
return null
}
companion object {

}

I can add more code per request. This is the full Github repo.

Here is the problem:
recyclerView = findViewById<RecyclerView>(R.id.userpass_recyclerview).apply{
layoutManager = layoutManager
adapter = adapter
}
Idk what's going on but it seems like you're initializing them to themselves. Don't do that. Its good practice to keep your variable names distinct. Refactor the objects like this:
internal lateinit var entryAdapter: EntryAdapter
private lateinit var linearLayoutManager: RecyclerView.LayoutManager
And make the following changes in your onCreate():
recyclerView = findViewById<RecyclerView>(R.id.userpass_recyclerview).apply{
adapter = entryAdapter
layoutManager = linearLayoutManager
}

How to load Data to imageView, after refresh of recycvlerview

I have two recyclerViews, which represent my grocery list.
When I click on an item it gets "transferred" to the other list.
The problem is that the images are loaded with Glide and Firebase Storage and they don't show the correct images even if the listitem does not have a path.
I have tried every notifyDataSetChanged(), recyclerView.notifyItemChanged() and recyclerView.invalidate() and others. Maybe you could help me.
This is my Adapter:
class RecyclerViewAdapterEinkaufslisteDetail(
val context: Context,
val lebensmittelList: ArrayList<Inventarstueck>
) :
RecyclerView.Adapter<RecyclerViewAdapterEinkaufslisteDetail.ViewHolder>() {
override fun onBindViewHolder(holder: RecyclerViewAdapterEinkaufslisteDetail.ViewHolder, position: Int) {
// TODO("not implemented") //To change body of created functions use File | Settings | File Templates.
//Es wird der Name, die Anzahl, die Einheit (gramm, kg, etc) das Bild und ein Warnzeichen angezeigt, falls ein Produkt abläufty
holder.mName.text = lebensmittelList[position].name_de.toString()
val array = holder.itemView.getContext().getResources().getStringArray(R.array.einheit_kurz)
val placeholder =
lebensmittelList[position].restlichemenge.toString() + " " + array[lebensmittelList[position].einheit!!]
holder.mAnzahl.text = placeholder
// holder.txtTitle.text = userList[position]

When I call the SetItemClickListener on the second recyclerView as well, then the whole process doesn't work.
It is very rare that there are two recyclerViews used so I haven't found anything either.
EDIT
I found the solution for my Problem:
I set the ImageView to a default picture, in case there is no URL.,
if (!(lebensmittelList[position].fotoURL.isNullOrEmpty() || lebensmittelList[position].fotoURL.isNullOrBlank())) {
.
.
. GlideApp.with(this.context).load(fotoRef).into(holder.mProduktfoto)
}else{
holder.mProduktfoto.setImageResource(R.drawable.logo_384_384)
}
