Show sqlite database records using cursor

I am not able to show records of SQLite table

my MySQLiteHelper class

public Cursor showImageRecords()
{
    Cursor cursor=db.query(TABLE_Name, new String[]{COLUMN1, COLUMN2}, null, null, null, null, null, null);
    return cursor;
}

I am calling selection query as

public void showImages()
{
    MySQLiteHelper mySQLiteHelper=new MySQLiteHelper(context, null, null, 1);
    mySQLiteHelper.openDatabase();    
    Cursor cursor=mySQLiteHelper.showImageRecords();

    while(cursor.moveToNext())
    {
        imagePath=cursor.getString(1);
        imageDate=cursor.getString(2);

        txtDetails.setText(imagePath+ "  " + imageDate +"\n");
    }
    cursor.close();
    mySQLiteHelper.closeDatabase();
}

logcat shows
