How to load ready sqlite db on android app?

Question

SQLite

A simple application written in Kotlin for Android with a SQLITE database. When running the application on another emulator, a new and empty database is created. How to sew a ready-made database into the application, already with certain data?

class SQLiteHelper(context: Context) :
    SQLiteOpenHelper(context, DATABASE_NAME, null, DATABASE_VERSION){

    companion object{
        private const val DATABASE_VERSION = 1
        private const val DATABASE_NAME = "students.db"
        private const val TBL_STUDENT = "tbl_student"

        private const val ID = "id"
        private const val NAME = "name"
        private const val EMAIL = "email"
    }

    override fun onCreate(db: SQLiteDatabase?) {
        val createTblStudent = ("CREATE TABLE " + TBL_STUDENT + "(" + ID
                + " INTEGER PRIMARY KEY, " + NAME + " TEXT," + EMAIL + " TEXT" + ")")
        db?.execSQL(createTblStudent)
    }

    override fun onUpgrade(db: SQLiteDatabase?, oldVersion: Int, newVersion: Int) {
        db!!.execSQL("DROP TABLE IF EXISTS $TBL_STUDENT")
        onCreate(db)
    }

    fun insertStudent(std: StudentModel): Long{
        val db = this.writableDatabase

        val contextValue = ContentValues()
        contextValue.put(ID, std.id)
        contextValue.put(NAME, std.name)
        contextValue.put(EMAIL, std.email)

        val success = db.insert(TBL_STUDENT, null, contextValue)
        db.close()
        return success
    }

    fun getAllStudent(): ArrayList<StudentModel>{
        val stdList: ArrayList<StudentModel> = ArrayList()
        val selectQuery = "SELECT * FROM $TBL_STUDENT"
        val db = this.readableDatabase

        val cursor: Cursor?

        try{
            cursor = db.rawQuery(selectQuery, null)
        }catch (e: Exception){
            e.printStackTrace()
            db.execSQL(selectQuery)
            return ArrayList()
        }

        var id: Int
        var name:String
        var email: String
        if(cursor.moveToFirst()){
            do{
                id = cursor.getInt(cursor.getColumnIndex("id"))
                name = cursor.getString(cursor.getColumnIndex("name"))
                email = cursor.getString(cursor.getColumnIndex("email"))

                val std = StudentModel(id = id, name = name, email = email)
                stdList.add(std)
            }while (cursor.moveToNext())
        }
        return  stdList
    }

    fun updateStudents(std: StudentModel) : Int{
        val db = this.writableDatabase

        val contentValues = ContentValues()
        contentValues.put(ID, std.id)
        contentValues.put(NAME, std.name)
        contentValues.put(EMAIL, std.email)

        val success = db.update(TBL_STUDENT, contentValues, "id = " + std.id, null)
        db.close()
        return success
    }

    fun deleteStudentById(id: Int): Int{
        val db = this.writableDatabase

        val contentValues = ContentValues()
        contentValues.put(ID,id)
        val success = db.delete(TBL_STUDENT, "id=$id", null)
        db.close()
        return success
    }
}

Along with the application, transfer the students.db.
