无法在Android的SqLite数据库中插入数据

Question

这是我保存数据的类

public class Report {

    public String report_title="";
    public String report_descrption="";
    public String report_category="";
    public String report_location_name="";
    public String report_lat;
    public String report_long;
    public String report_media="";
}

这是我在数据库中插入一行的数据库处理程序类。

public class DatabaseHandler extends SQLiteOpenHelper{
    private static final String LOG = DatabaseHandler.class.getName();

    // Database version
    private static final int DATABASE_VERSION = 1;

    // Database Name
    private static final String DATABASE_NAME = "reportsManager";

    // Table names
    private static final String TABLE_REPORT= "report";

    // Helper Table Columns names

    private static final String REPORT_TITLE="title";
    private static final String REPORT_DESCRIPTION="description";
    private static final String REPORT_CATEGORY="category";
    private static final String REPORT_LOCATION_NAME="location";
    private static final String REPORT_LAT="latitude";
    private static final String REPORT_LONG="logitude";
    private static final String REPORT_MEDIA="media";


    // Helper table create statement
    private static final String CREATE_TABLE_REPORT = "CREATE TABLE "
            + TABLE_REPORT + " ( " + REPORT_TITLE + " TEXT, " + 
            REPORT_DESCRIPTION+ " TEXT, " + REPORT_CATEGORY + " TEXT," + REPORT_LOCATION_NAME +
            " TEXT, "+ REPORT_LAT+" TEXT, "+ REPORT_LONG+" TEXT, "+REPORT_MEDIA+" TEXT"+")";

    // Constructor
    public DatabaseHandler(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        //Creating required tables
        db.execSQL(CREATE_TABLE_REPORT);
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL("DROP TABLE IF EXISTS " + CREATE_TABLE_REPORT);    
        // create new tables
        onCreate(db);
    }

    void addReport(Report reports) {

        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues values = new ContentValues();

        values.put(REPORT_TITLE, reports.report_title);
        values.put(REPORT_DESCRIPTION, reports.report_descrption);
        values.put(REPORT_CATEGORY, reports.report_category);
        values.put(REPORT_LOCATION_NAME, reports.report_location_name);
        values.put(REPORT_LAT, reports.report_lat);
        values.put(REPORT_LONG, reports.report_long);
        values.put(REPORT_MEDIA, reports.report_media);
        // Inserting Row
        db.insert(TABLE_REPORT, null, values);
        db.close(); // Closing database connection
    }        
}

现在，如果我插入数据库，LogCat会发生以下错误。有人可以帮帮我吗？

android.database.sqlite.SQLiteException: table report has no column named logitude: , while compiling: INSERT INTO report(category,title,logitude,latitude,media,location,description) VALUES (?,?,?,?,?,?,?)
