Syntax Error while adding data using SqLite in Android

i am newbie in android, trying to add data in SqLite Database. i am adding name and number in database but i am getting syntax error. i checked many sites but i hardly found any syntax error. if anyone can give any kind of help, i will be thankful. here is my code :

@Override
    public void onCreate(SQLiteDatabase db) 
{
        String tablecreate = "create table " + tableName + " ( " + ID
                + " INTEGER PRIMARY KEY AUTOINCREMENT, " + NAME + " TEXT,"
                + NUMBER + " TEXT )";

        db.execSQL(tablecreate);
    }

public void addContact(String name, String num) {
        SQLiteDatabase database = this.getWritableDatabase();
        ContentValues cv = new ContentValues();
        cv.put(NAME, name);
        cv.put(NUMBER, num);
        database.insert(tableName, null, cv);
        database.close();
    }

and here is what log cat says :
