4. Database Code public class PrideDB { private static final String FEEDS_TABLE = "feeds"; private static final String DATABASE_NAME = "pride"; private static SQLiteDatabase db; public PrideDB(Context ctx) { db = ctx.openOrCreateDatabase(DATABASE_NAME, 0, null); //API change } Purdue Pride

5. Database Code public static booleaninsertItem(String title, String description) { ContentValues values = new ContentValues(); values.put("title", title); values.put("description", description); return(db.insert(FEEDS_TABLE, null, values) > 0); } public booleandeleteItem(Long feedID) { return(db.delete(FEEDS_TABLE, "feed_id=" + feedID.toString(), null) > 0); } public static List<RSSItem> getItems() { ArrayList<RSSItem> feeds = new ArrayList<RSSItem>(); try { Cursor c = db.query(FEEDS_TABLE, new String[] {"feed_id", "title", "description"} , null, null, null, null, null); intnumRows = c.getCount(); //API change for( int i =0; i < numRows; ++i) { RSSItem item = new RSSItem(); item.feedId = c.getLong(0); item.title = c.getString(1); item.description = c.getString(2); feeds.add(item); c.moveToNext(); //API change } } Purdue Pride

6. Database Code catch (SQLException e) { Log.e("PurduePride",e.toString()); } return feeds; } public static RSSItemgetItem() { RSSItem item = new RSSItem(); try { Cursor c = db.query(FEEDS_TABLE, new String[] {"feed_id", "title", "description"} , null, null, null, null, null); item.feedId = c.getLong(0); //item.title = c.getString(1); //item.description = c.getString(2); } catch (SQLException e) { Log.e("PurduePride",e.toString()); } return item; } } Purdue Pride

7. RSS Handler if (item.title != null) {PrideDB.insertItem(item.title, item.description);item.title = null;item.description = null;                 /*itemsAdded++;                 if (itemsAdded >= ARTICLES_LIMIT) {                     throw new SAXException();                 }                 */             } Purdue Pride

8. Pride RSS handler.setContext(this); Purdue Pride
