Opening SQLite database in Android Studio Kotlin - sqlite

Question

I'm very new to Kotlin so please bear with me. I want to open a SQLite database or create it if it doesn't exist yet. Afterwards I'd run the appropriate statements to make a table, etc. I'm trying to use SQLiteDatabase. The line of code I'm trying is:
val db = SQLiteDatabase.openOrCreateDatabase("database.db",null, SQLiteDatabase.OPEN_READWRITE)
I get this runtime error when I try the app:
android.database.sqlite.SQLiteCantOpenDatabaseException: unknown error (code 1294 SQLITE_CANTOPEN_ENOENT[1294]): Could not open database
I'm not picky about the database, I just want an easy way to read and write to one from within my function.
This is the surrounding code:
package com.google.firebase.codelab.barcode_scanning
// Date/time formatting functions
import android.database.sqlite.SQLiteDatabase
import android.graphics.Color
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.recyclerview.widget.RecyclerView
import kotlinx.android.synthetic.main.item_row.view.*
import java.time.LocalDateTime
import java.time.format.DateTimeFormatter
class QrCodeAdapter(private val qrList: ArrayList<QrCode>) : RecyclerView.Adapter<QrCodeAdapter.QrHolder>() {
//
override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): QrHolder {
return QrHolder(LayoutInflater.from(parent.context).inflate(R.layout.item_row, parent, false))
}
override fun getItemCount() = qrList.size
override fun onBindViewHolder(holder: QrHolder, position: Int) {
//internal var dbHelper = DatabaseHelper(this)
with(qrList[position]) {
var objname = "Barcode Not Found"
var statustext = ""
// status: 0 = no record, 1 = dirty, 2 = clean, 3 = dwell, 4: dwell done
var status = 0
var lastcleaned = ""
// objcategory: 0 = no record, 1 = contact object, 2 = dwell item
var objcategory = 0
var objcategorytext = ""
// initial setup of current date/time
var unixtime = System.currentTimeMillis()
var currenttime = LocalDateTime.now()
var timeformat = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss.SSS")
var testtime = currenttime.format(timeformat).toString()
//val db = SQLiteDatabase.openDatabase("//app/maindb.db", null, 0);
val db = SQLiteDatabase.openOrCreateDatabase("database.db",null, null)
//val sql = "SELECT COUNT(*) FROM main"
//val statement = db.compileStatement(sql)
//val result = statement.simpleQueryForLong()
//Convert barcode output to string
var barcodevalue = this.value.toString()
// hide settings
holder.itemView.textSettingsTitle.visibility=View.GONE
holder.itemView.textboxName.visibility=View.GONE
