Android : diificulty in getting cursor data and store it in a string

Hey i m learning android, and having some trouble in sqLite database.. I want to get a specific set of rows from a column through cursor and store it in string array to display it in textview. this is the method i m using to get the cursor data

public String[] getDetailedSymps(long sympId) {

    String[] columns2 = new String[] { KEY_SYMP_DETAIL, KEY_SYM_ID };
    String details[]= new String[9];
    int i=0;


    Cursor c3 = ourDatabase.query(DATABASE_TABLE2, columns2, KEY_SYM_ID + "=" + sympId, null, null, null, null);
    int iDetail = c3.getColumnIndex(KEY_SYMP_DETAIL);
    while (c3.isAfterLast() == false) {

    details[i]= c3.getString(iDetail);
    i++;
    c3.moveToNext();
    }

        return details;

But ,when i ran the code , it gave me the error CursorIndexOutOfBoundException,: index -1 requested with a size of 9, here is the logcat
