Webview Camera, Audio permission issue

The video calling feature was working perfectly with webview until almost 3 months ago. Recently it's not supporting camera and audio functionality, even browser and application have both of these permissions. I would like to know if it is because of any recent update with webview or Chromium or with anything else, as it was working properly before.
Below is the method used to load the URL:
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
getBindingModel().webView.settings.javaScriptEnabled = true
getBindingModel().webView.settings.mediaPlaybackRequiresUserGesture = false
getBindingModel().webView.webViewClient = object : WebViewClient() {
override fun shouldOverrideUrlLoading(view: WebView, url: String): Boolean {
view.loadUrl(url)
return false
}
}
getBindingModel().webView.webChromeClient = object : WebChromeClient() {
override fun onProgressChanged(view: WebView?, newProgress: Int) {
getBindingModel().loadingText.text = "$newProgress%"
getBindingModel().loadingText.visibility =
if (newProgress > 99) View.GONE else View.VISIBLE
getBindingModel().progress.visibility =
if (newProgress > 99) View.GONE else View.VISIBLE
}
override fun onPermissionRequest(request: PermissionRequest?) {
runOnUiThread { request?.grant(request.resources) }
}
}
}

Implement Geojson points to map and locate me with Mapbox, in Kotlin on Android Studio

My question is about Mapbox. In this period I am working on an ANDROID application based on mapbox, using Kotlin and Fragments and my problem concerns the visualization of points on the map itself. That is my need is to be able to show points on the map through a GEOJSON file, for now I have been able to see the map in full in the application, but I cannot find a way to show the points taken from a GeoJson file and locate myself in the map via a button.
I should implement both functions in the fragment, so my problem is precisely that of not being able to show the points of a geojson file and find a way to locate myself in the map itself. I await help if there is someone able to help me with this problem, I also leave the code of the fragment class in kotlin.
Thanks everyone in advance !!

You'll need to use a GeoJsonSource. https://github.com/mapbox/mapbox-android-demo/search?q=GeoJsonSource shows how the demo app uses the source.
https://github.com/mapbox/mapbox-android-demo/blob/master/MapboxAndroidDemo/src/main/java/com/mapbox/mapboxandroiddemo/examples/basics/KotlinSupportMapFragmentActivity.kt (Its XML layout file)
Putting icons on the map. https://docs.mapbox.com/android/maps/examples/marker-symbol-layer/. Do all of the icon setup inside of the fragment's onStyleLoaded() callback as seen at https://github.com/mapbox/mapbox-android-demo/blob/master/MapboxAndroidDemo/src/main/java/com/mapbox/mapboxandroiddemo/examples/basics/KotlinSupportMapFragmentActivity.kt#L51-L55
https://github.com/mapbox/mapbox-android-demo/search?q=loadGeojson shows how the demo app loads from a GeoJson file. You could use coroutines instead of building out the AsyncTask.
Although it's in Java, https://docs.mapbox.com/android/maps/examples/show-a-users-location-on-a-fragment/ shows how to combine the Maps SDK's LocationComponent with a fragment.
Regarding moving the camera to the device's last known location when a button is clicked, see my answer at https://stackoverflow.com/a/64159178/6358488

How to notify and update list when item has been deleted using Groupie RecyclerView library and Kotlin

I have a RecyclerView implemented with the Groupie library and I can delete an item from the list fine, however need to update the view to see the change. I'd like to have something like notifyDataSetChanged() instead, so the list updates immediately. I'm a bit confused at this stage though, tried a few different ways to get an interface from the class that hosts my view holder to be triggered from the fragment that holds the adapter but I think I'm stuck now if I could get some help please.
class RecyclerProductItem(
private val activity: MainActivity,
private val product: Product, private val adapterListener: AdapterListener
) : Item<GroupieViewHolder>() {
companion object {
var clickListener: AdapterListener? = null
}
override fun bind(viewHolder: GroupieViewHolder, position: Int) {
viewHolder.apply {
with(viewHolder.itemView) {
clickListener = adapterListener
ivTrash.setOnClickListener(object : View.OnClickListener {
override fun onClick(v: View?) {
if (clickListener != null) {
Toast.makeText(context, "delete method to be added here", Toast.LENGTH_SHORT).show()
clickListener?.onClickItem(position)
}
}
})
}
}
}
override fun getLayout() = R.layout.recyclerview_item_row
interface AdapterListener {
fun onClickItem(position: Int)
}
}
Here it's my fragment. I tried to add a section to the adapter to see if it would allow me to retrieve a listener for it, but as my listener should be triggered under a specific item within the layout, this may not be the best solution, although couldn't make this work either.
class ProductsListFragment : Fragment(), RecyclerProductItem.AdapterListener {
private lateinit var adapter: GroupAdapter<GroupieViewHolder>
private val section = Section()
override fun onCreateView(
inflater: LayoutInflater,
container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
return inflater.inflate(R.layout.fragment_products_list, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val linearLayoutManager = LinearLayoutManager(activity)
recyclerView.layoutManager = linearLayoutManager
adapter = GroupAdapter()
adapter.add(section)
recyclerView.adapter = adapter
loadProducts()
}
private fun loadProducts() {
GetProductsAPI.postData(object : GetProductsAPI.ThisCallback {
override fun onSuccess(productList: List<JsonObject>) {
for (jo in productList) {
val gson = GsonBuilder().setPrettyPrinting().create()
val product: Product =
gson.fromJson(jo, Product::class.java)
adapter.add(
RecyclerProductItem(
activity as MainActivity,
Product(
product.id,
product.title,
product.description,
product.price
),adapterListenerToBePassedHere
)
) // This part is where I should be giving the listener, but get a red line since not sure how to get it to include it here.
}
}
})
}
companion object {
fun newInstance(): ProductsListFragment {
return ProductsListFragment()
}
}
override fun onClickItem(position: Int) {
adapter.notifyItemRemoved(position)
}
}
Many thanks.

I think you are missing this concept from the groupie Readme:
Modifying the contents of the GroupAdapter in any way automatically sends change notifications. Adding an item calls notifyItemAdded(); adding a group calls notifyItemRangeAdded(), etc.
So to remove an item, call section.remove(item). However, in your onClickItem function you currently only pass the position. Pass the item like clickListener?.onClickItem(this#RecyclerProductItem) instead.
Even more ideally and safely you should remove by product.id, e.g. clickListener?.onClickItem(this#RecyclerProductItem.product.id) then in onClickItem() you just search for the item with that product id and remove it. Let me know if I'm not clear.

Based on #carson's reply, this is what worked for me. Had to add the items to the section, the section to the adapter and then remove the item from the section based on the adapter position once that listener is clicked, passing the method that implements the listener as one of the arguments to complete the GroupAdapter.
class RecyclerProductItem(
private val activity: MainActivity,
private val product: Product, private val adapterListener: AdapterListener
) : Item<GroupieViewHolder>() {
companion object {
var clickListener: AdapterListener? = null
}
override fun bind(viewHolder: GroupieViewHolder, position: Int) {
viewHolder.apply {
with(viewHolder.itemView) {
tvTitle.text = product.title
clickListener = adapterListener
ivTrash.setOnClickListener(object : View.OnClickListener {
override fun onClick(v: View?) {
if (clickListener != null) {
Toast.makeText(context, "delete method to be added here", Toast.LENGTH_SHORT).show()
clickListener?.onClickItem(this#RecyclerProductItem.product.id, adapterPosition)
}
}
})
}
}
}
override fun getLayout() = R.layout.recyclerview_item_row
interface AdapterListener {
fun onClickItem(id: Int, position: Int)
}
}
And
private fun loadProducts() {
GetProductsAPI.postData(object : GetProductsAPI.ThisCallback,
RecyclerProductItem.AdapterListener {
override fun onSuccess(productList: List<JsonObject>) {
Log.i(LOG_TAG, "onSuccess $LOG_TAG")
for (jo in productList) {
val gson = GsonBuilder().setPrettyPrinting().create()
val product: Product =
gson.fromJson(jo, Product::class.java)
val linearLayoutManager = LinearLayoutManager(activity)
recyclerView.layoutManager = linearLayoutManager
adapter = GroupAdapter()
section.add(
RecyclerProductItem(
activity as MainActivity,
Product(
product.id,
product.title,
product.description,
product.price
), this
)
)
adapter.add(section)
recyclerView.adapter = adapter
}
}
override fun onFailure() {
Log.e(LOG_TAG, "onFailure $LOG_TAG")
}
override fun onError() {
Log.e(LOG_TAG, "onError $LOG_TAG")
}
override fun onClickItem(id: Int, position: Int) {
section.remove(adapter.getItem(position))
}
})
}

Bind custom DialogFragment to service initialized into Application scope

I'm working to an application that makes some webcalls and I want to add a DialogFragment (with a ProgressBar at the center) that shows when I'm waiting for the call to complete.
Webcalls are extended from AsyncTask with a private library that gives an interface (DialogInterface) to set what to do when the dialog it's shown and hidden.
For the DialogFragment I've found some nice code from here:
https://code.luasoftware.com/tutorials/android/android-show-loading-and-prevent-touch/
It works without problems from an Activity class, but the DialogInterface has to be set to the WebService builder which is initialized into the Application class
This is the init sequence in the Application class
WebService.init(
WebServiceBuilder(this)
.setBaseUrlTest("http://google.it/")
.setUrlType(UrlType.TEST)
.setDialogInterface(object : DialogInterface {
override fun showDialog(context: Context?) {
if (context != null)
val busyDialog = BusyDialogFragment.show(supportFragmentManager)
}
override fun hideDialog() {
//code that hide the DialogFragment
}
})
Obviously in the Application class I cannot get the FragmentManager so this code doesn't works.

You can register an ActivityLifecycleCallbacks in the Application class to know which activity is currently running, and get the FragmentManager:
class MyApplication : Application() {
private var currentActivityRef : WeakReference<FragmentActivity?>? = null
private val supportFragmentManager : FragmentManager?
get() = currentActivityRef?.get()?.supportFragmentManager
override fun onCreate() {
super.onCreate()
registerActivityLifecycleCallbacks(object : ActivityLifecycleCallbacks {
override fun onActivityStarted(activity: Activity?) {
currentActivityRef = WeakReference(activity as? FragmentActivity)
}
override fun onActivityStopped(activity: Activity?) {
currentActivityRef = null
}
override fun onActivityPaused(activity: Activity?) {}
override fun onActivityResumed(activity: Activity?) {}
override fun onActivityDestroyed(activity: Activity?) {}
override fun onActivitySaveInstanceState(activity: Activity?,
outState: Bundle?) {
}
override fun onActivityCreated(activity: Activity?,
savedInstanceState: Bundle?) {
}
})
}
}

RecyclerView adapter not working with groupie

I tried to add groupie adapter to my recycler view as shown in the code below. However when i run my application, i get a compiler error saying my reyclerview cannot be null (because of kotlin null safe feature). I cant figure out why this adapter is not working.
I know the problem is in the line :
recyclerview_newmessage.adapter = adapter
Here's the full code
class NewMessageActivity : AppCompatActivity() {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
supportActionBar?.title = "Select User"
fetchUsers()
}
private fun fetchUsers() {
val ref = FirebaseDatabase.getInstance().getReference("/users")
ref.addListenerForSingleValueEvent(object: ValueEventListener {
override fun onCancelled(p0: DatabaseError) {
}
override fun onDataChange(p0: DataSnapshot) {
val adapter = GroupAdapter<ViewHolder>()
p0.children.forEach {
Log.d("NewMessage", it.toString())
val user = it.getValue(User::class.java)
if (user != null) {
adapter.add(UserItem(user))
}
}
recyclerview_newmessage.adapter = adapter
}
})
}
}
class UserItem(val user: User): Item<ViewHolder>() {
override fun bind(viewHolder: ViewHolder, position: Int) {
viewHolder.itemView.username_textview_new_message.text = user.username
}
override fun getLayout(): Int {
return R.layout.user_row_new_message
}
}
The final result show display the rows in the recycler view with the usernames that are in my firebase database.

If you define the recycler view in the xml file then you need to add it.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.ref_xml_file) . // add this line
supportActionBar?.title = "Select User"
fetchUsers()
}
if not define into the xml file.
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
var recyclerview_newmessage = RecyclerView(this)
setContentView(recyclerview_newmessage) . // add this line
supportActionBar?.title = "Select User"
fetchUsers()
}
