Unable To Load ImageView from External Storage RecyclerView - firebase

Question

I am working on an Android app which has to load all QR created image from external storage to the fragment which contains a RecyclerView. All the work goes fine, but as I tried to load the image from the specific path from external storage directory, it fails to load and throws an exception..
I am stuck with this as I have given the path to it like
override fun onBindViewHolder(holder: ItemHolder, position: Int) {
val charItemcreate: CharItemsCreate = arrayList.get(position)
val path: String = Environment.getExternalStorageDirectory().toString() + "Maximus/QRCreated/"
val bitmap = BitmapFactory.decodeFile(path)
//holder.images = charItemcreate.imageload.toIcon()
}
Here is the Layout I Created For RecyclerView..
<androidx.constraintlayout.widget.ConstraintLayout
android:id="#+id/constmain"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
tools:ignore="MissingConstraints">
<ImageView
android:layout_width="#dimen/_62sdp"
android:layout_height="#dimen/_62sdp"
android:id="#+id/imgrecyclerviewcreate"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
/>
<TextView
android:id="#+id/txt_nametext"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toEndOf="#id/imgrecyclerviewcreate"
android:text="#string/email"/>
<TextView
android:id="#+id/txt_detail"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_constraintStart_toEndOf="#id/imgrecyclerviewcreate"
app:layout_constraintTop_toBottomOf="#+id/txt_nametext"
android:text="#string/email"/>
</androidx.constraintlayout.widget.ConstraintLayout>
The Adapter Class I have Created where i have Given the Images Folder path
class AdapterCreateHistory(var context: Context, var arrayList: ArrayList<CharItemsCreate>) :
RecyclerView.Adapter<AdapterCreateHistory.ItemHolder>() {
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): ItemHolder {
val viewHolder = LayoutInflater.from(parent.context)
.inflate(R.layout.createhistoryitem, parent, false)
return ItemHolder(viewHolder)
}
override fun getItemCount(): Int {
return arrayList.size
}
override fun onBindViewHolder(holder: ItemHolder, position: Int) {
val charItemcreate: CharItemsCreate = arrayList.get(position)
val path: String = Environment.getExternalStorageDirectory().toString() + "Maximus/QRCreated/"
val bitmap = BitmapFactory.decodeFile(path)
//holder.images = charItemcreate.imageload.toIcon()
}
class ItemHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {
var images = itemView.findViewById<ImageView>(R.id.imgrecyclerviewcreate)
}
Here is the Kotlin Model Class
class CharItemsCreate {
var imageload: Bitmap? = null
constructor(imageload: Bitmap) {
this.imageload = imageload
}
}
Here is the Main Fragment I am Working on. In Here I have Initialez the RecyclerView and the CharItemClass
class FragmentViewPagerScanHistory : Fragment() {
private var charItemcreate: ArrayList<CharItemsCreate>? = null
private var customAdaptercreate: AdapterCreateHistory? = null
private var gridLayoutManager: GridLayoutManager? = null
//val TYPE_SAVED = 15
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
}
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_view_pager_scan_history, container, false)
}
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
gridLayoutManager = GridLayoutManager(context, 1, LinearLayoutManager.VERTICAL, false)
recyclerviewcreatehistory?.layoutManager = gridLayoutManager
recyclerviewcreatehistory?.setHasFixedSize(true)
charItemcreate = setImages()
customAdaptercreate = AdapterCreateHistory(this.context ?: return, charItemcreate!!)
recyclerViewfragment?.adapter = customAdaptercreate
}
private fun setImages(): ArrayList<CharItemsCreate>? {
return charItemcreate
}
I am Unable to Load Images into RecyclerView as I Am Getting Exception . I have Attached the Debugger With this It Also Give me the Null Values...
I have Also Given the Read Permission in the Manifest
Here is the Logcat After It Crashed

Hello you can use Glide or picasso library, that will handle exception in very appropriate way,
here is the implementation of Glide :-
implementation 'com.github.bumptech.glide:glide:4.11.0'
This is is the code block :-
Glide.with(context).load(yourpath).centerCrop().error(image that place while error occure).into(imageview);
