Drawable doesn't display image that inserted in Callback - android

I'm currently building a application that takes data from database and displays the information.
I looked at those solutions but it didn't work:
android.content.res.Resources$NotFoundException: Resource ID #0x7f07007e
Android ResourcesNotFoundException however image present in all drawable folders
Here is my error message:

This is how I'm trying to populate data:
INSTANCE = Room.databaseBuilder(
context.applicationContext,
PlantDatabase::class.java, DB_NAME
)
.fallbackToDestructiveMigration()
.addCallback(object : Callback() {
override fun onCreate(db: SupportSQLiteDatabase) {
super.onCreate(db)
Executors.newSingleThreadScheduledExecutor()
.execute(Runnable {
INSTANCE?.plantDao()!!
.insertAll(Plant(1,"Aloe", R.drawable.plantlogo,"Aloe","1 per week","Dangerous for pets"))
})
}
})
.build()
Here is how I set my Imagine in adapter:
override fun onBindViewHolder(holder: ViewHolder, position: Int) {
// Get the data model based on position
var data = dataList[position]
holder.title.text = data.name
holder.desc.text = data.type.toString()
holder.image.setImageResource(data.image) // Error message indicates that this line has error
holder.relativeLayout.setOnClickListener { view -> //Toast.makeText(view.getContext(),"click on item: "+model.getTitle(),Toast.LENGTH_LONG).show();
val intent = Intent(view.context, PlantDetails::class.java)
intent.putExtra("plant_name", data.name)
intent.putExtra("plant_image", data.image)
intent.putExtra("plant_type", data.type)
intent.putExtra("plant_water", data.water_time)
intent.putExtra("plant_details", data.details)
view.context.startActivity(intent)
}
}
The data class:
#Entity(tableName = "Plant")
data class Plant(
#PrimaryKey var plant_id:Long,
#ColumnInfo (name="plant_name") var name: String,
//#Embedded var type: Plant_Category,
#ColumnInfo(name= "plant_image") var image: Int,
#ColumnInfo(name="plant_type_name") var type:String ="",
#ColumnInfo(name="plant_type_water")var water_time: String ="",
#ColumnInfo(name="plant_type_details")var details: String = "",
) {
}
Here is the log of data.image:
 data.image log: 1
The error message indidcaes that I didn't set Image properly but before adding the Database I tested with the ArrayList and I didn't have any issues.
I will be thankful for your help.

below my code to gist

You are using a wrong key for members in your Group data class, it is data while in your json it shows the key is members
use the following class and it will work
data class Group(
#SerializedName("group_id")
val group_id: Int,
#SerializedName("group_name")
val group_name: String,
#SerializedName("members")
val members: List<Member>
)

You are not using correct key
data class Group(
#SerializedName("group_id")
val group_id: Int,
#SerializedName("group_name")
val group_name: String,
#SerializedName("data")
val members: List<Member>)
According to your json schema it should be
data class Group(
#SerializedName("group_id")
val group_id: Int,
#SerializedName("group_name")
val group_name: String,
#SerializedName("members")
val members: List<Member>)

RecyclerView Inconsistency on notify adapter

items.clear()
viewAdapter.notifyItemRangeRemoved(0, size)
Also this:
val position = items.indexOf(elem)
items.remove(elem)
viewAdapter.notifyItemRemoved(position)
What I'm missing?

for (child in children)
{
items.add(book)
}
viewAdapter.notifyItemInserted(items.count()-1)
Please keep notifyItemInserted outside the loop and check it.

Issue with base adapter in Kotlin

I am using listview in my android project. For this I have created a child of BaseAdapter. But I am getting error and app is crashing.
override fun onActivityCreated(savedInstanceState: Bundle?) {

val restaurantListView:ListView? = activity?.findViewById(R.id.restaurant)
restaurantListView?.adapter = RestaurantAdapter()
}
}
class RestaurantAdapter:BaseAdapter()
{
override fun getCount(): Int {

}
override fun getItem(position: Int): Any {
return Any()
}
override fun getItemId(position: Int): Long {
return 0
}
override fun getView(position: Int, convertView: View?, parent: ViewGroup?): View? {

Android Spinner Fatal Exception: java.lang.ArrayIndexOutOfBoundsException: length=0; index=-1

We recently went live with an app after months of testing and we are getting an exception related to a Spinner (only Samsung devices so far). Although we have the stacktraces, we can't gather much information from them so I was hoping someone could offer some help.
The issue is related to a HintAdapter. It seems the adapter has zero items when getItem and getView are called. We don't really understand how this is happening, but what is really concerning us is why the index being requested is -1. How can someone select a negative index?
Here is the stacktrace:

Here is the HintArrayAdapter getItem and getView methods:
public T getItem(int position)
{
return optionElements.get(position);
}
public View getView(int position, View convertView, #NonNull ViewGroup parent)
{
ViewHolder viewHolder;
if (convertView == null)
{
viewHolder = new ViewHolder();
LayoutInflater inflater = LayoutInflater.from(this.getContext());
convertView = inflater.inflate(R.layout.search_spinner_item, parent, false);
viewHolder.textView = (TextView) convertView.findViewById(R.id.search_spinner_item_text_view);
convertView.setTag(viewHolder);
}
else
{
viewHolder = (ViewHolder) convertView.getTag();
}
T optionElement = getItem(position);
if (optionElement != null)
{
String textToDisplay = getViewText(optionElement);
viewHolder.textView.setText(textToDisplay);
}
return convertView;
}

It seems you are trying to select an element in your array of data that doesn't exist, the log says that you don't have any element but trying to reach index 1.
