Ошибка при работе в android через sqlite3

При вызове кнопки READ выходит ошибка. При удалении и при добавлении строк в таблицу все хорошо , а так же если закоментировать cursor.getInt(idIndex) то ошыбка не выходит.

вот активность MainActivity

класс работы с Базой данных

package com.example.testbasadate;

import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;

import androidx.annotation.Nullable;

public class dBHelper extends SQLiteOpenHelper {

    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "contactDb";
    public static final String TABLE_CONTACTS = "contacts";

    public static final String KEY_ID = "_id";
    public static final String KEY_NAME = "name";
    public static final String KEY_MAIL = "mail";

    public dBHelper(@Nullable Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }


    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL("CREATE TABLE " + TABLE_CONTACTS + " (" + KEY_ID + "INTEGER PRIMARY KEY, " + KEY_NAME + " TEXT," + KEY_MAIL + " TEXT" + " )");

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + TABLE_CONTACTS);

        onCreate(db);
    }
}
