Obtain browser bookmarks from the database (Android browser Development)

Sometimes the browser's bookmarks may be used. You can use the following code to obtain the information.

Contentresolver = getcontentresolver (); cursor = contentresolver. query (browser. bookmarks_uri, browser. history_projection, whereclause, null, orderby); While string orderby = browser. bookmarkcolumns. visits + "DESC"; string whereclause = browser. bookmarkcolumns. bookmark + "= 1 ";

Orderby refers to the sorting method, and whereclause is the selection condition. In this way, you can obtain the bookmarks of the self-contained browser in Android.

Then, we can define three arraylists to store information obtained from the database.

 listTitle = new ArrayList<String>();        listUrl = new ArrayList<String>();        listBitmap = new ArrayList<Bitmap>();

Traverse cursor and save the information to arraylist:

 while(cursor!=null && cursor.moveToNext()){            listTitle.add(cursor.getString(cursor.getColumnIndex(Browser.BookmarkColumns.TITLE)));            listUrl.add(cursor.getString(cursor.getColumnIndex(Browser.BookmarkColumns.URL)));            byte[] b = cursor.getBlob(cursor.getColumnIndex(Browser.BookmarkColumns.THUMBNAIL));            if(b!=null){                listBitmap.add(BitmapFactory.decodeByteArray(b, 0, b.length));            }else{                listBitmap.add(((BitmapDrawable)(getResources().getDrawable(R.drawable.ic_launcher_browser))).getBitmap());            }        }
