hi i am new in android and kotlin and i have a chat app that will work with sms and want save state of all chat for next run
i did use recyclerView and GroupieViewHolder for show chats , i see some post here but all was with java but i am using kotlin for this app
so if you can please help me and If possible, state the easiest way in the simplest possible way
app screenshot:
my smsActivity.kt:
class smsActivity : AppCompatActivity() {

If you want ensure that Activity re-creation doesn't destroy your content, you can refer to this answer
If you want to connect the data to your local Storage, I suggest you using Room

If you see the read messages function in my activity class below, i wanted to update the isSeen field in firestore, but for some reason it does not work at all. My guess it requires a specific document value but that would not be possible as this a messaging app so there will be a lot of documents created.
Activity Class
class MessageActivity : AppCompatActivity() {
private lateinit var binding: ActivityMessageBinding
private lateinit var chat: ArrayList<Message>
private lateinit var messageAdapter: MessageAdapter
private lateinit var roomID: String
private lateinit var userID: String

private var c: Int = 0
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
binding = ActivityMessageBinding.inflate(layoutInflater)
setContentView(binding.root)
userID = FirebaseAuth.getInstance().uid.toString()
recID = intent.getStringExtra("userID").toString()
val recName:String = intent.getStringExtra("userName").toString()
binding.userName.text = recName
chat = arrayListOf()
messageAdapter = MessageAdapter(chat)
binding.recyclerView.setHasFixedSize(true)
binding.recyclerView.layoutManager = LinearLayoutManager(this)
when {
userID < recID ->
{
roomID = userID + recID
}
userID.compareTo(recID) == 0 ->
{
Toast.makeText(this, "Error you are chatting with yourself!!!", Toast.LENGTH_SHORT).show()
}
else -> {
roomID = recID + userID
}
}
readMessages(userID,recID)
binding.btnSend.setOnClickListener {

Firestore
This won't work:
rootRef.collection("chats").document(roomID).collection("messages").document().update("isSeen",true)
The document() call without any arguments creates a reference to a new non-existing document, which you then try to update. But update() only works when a document already exists, you can't use update() to create a document, so this code ends up doing nothing.
To update a document, you need to specify the complete path to that document. The fact that you need to update a lot of documents makes no difference to that fact, it just means you'll need to paths to a lot of documents.
As far as I can tell, you are trying to update the document that you read in documentSnapshots, which means you already have the DocumentReference handy and can update it with:
queryDocumentSnapshots.reference.update("isSeen",true)
In my app, there is an EditText that shows date picker dialog and also a spinner. The spinner item contains data from database that is filled after date is set.
It was working normal until in some occasion that I couldn't replicate the error, it shows "Job was cancelled" in Logcat. And when it happened, the spinner is empty.

As you can see, here on override fun onDateSet(view: DatePicker?, year: Int, month: Int, dayOfMonth: Int), I'm doing a check whether month now is the same as the month that is selected from date picker dialog. If it's the same, the spinner is filled with a filtered data from database that is matched with the month. And if month now is not the same as the month that is selected, the spinner is filled with all data from database.
Rarely, after I set the date, it shows "Job was cancelled" and the spinner is blank. Most of the time it works, though.
Is there anyway I fix this?
P.S. the same coroutine is also used in other fragments. Even in class AddReportFragment, that coroutine is also used. Everything was fine. No "Job was cancelled". I don't know why sometimes it doesn't work on DatePickerDialog class
this is the chat functionality on my app but the messages aren't appearing on my app although it is getting updated in the firebase. when I hardcoded the values it is working. this is the conversation activity. I've used a chat fragment and adapter as well. But the messages are just not getting posted on the app. any alternative solutions or a solution for this would be nice.

I'm trying to integrate chatkit into my Android app grabbing portions of code from this getting started tutorial and this android-public-demo-app project on github and I am getting this error:

I think I know what happened.
I think what happened was I created a room from the pusher-chat kit dashboard and then tried to sign in as them. and then enter the room as them. I was able to see my chatroomlists that they were affiliated with however I think that since I created the chatroom from the dashboard, it thought I was someone else.
Long story short, it works if I create the room from my android emulator and then go to the room. if I create the room from the dashboard and try to join, it doesn't seem to work.
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() {
private var usernameEditText: EditText? = null
private var passwordEditText: EditText? = null

override fun onCreate(savedInstanceState: Bundle?) {

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
}
