Developing a Web Monitor in Android

I would like to monitor/filter the websites that an user opens in Android.

I know how to retrieve the last visited URL (in Android default browser) using a ContentObserver on the browser history...

private static class BrowserObserver extends ContentObserver { private static String lastVisitedURL = ""; private static String lastVisitedWebsite = ""; //Query values: final String[] projection = new String[] { Browser.BookmarkColumns.URL }; // URLs final String selection = Browser.BookmarkColumns.BOOKMARK + " = 0"; // history item final String sortOrder = Browser.BookmarkColumns.DATE; // the date the item was last visited public BrowserObserver(Handler handler) { super(handler); } @Override public void onChange(boolean selfChange) { onChange(selfChange, null); } @Override public void onChange(boolean selfChange, Uri uri) { super.onChange(selfChange); //Retrieve all the visited URLs: final Cursor cursor = getContentResolver().query(Browser.BOOKMARKS_URI, projection, selection, null, sortOrder); //Retrieve the last URL: cursor.moveToLast(); final String url = cursor.getString(cursor.getColumnIndex(projection[0])); //Close the cursor: cursor.close(); if ( !url.equals(lastVisitedURL) ) { // to avoid information retrieval and/or refreshing... lastVisitedURL = url; //Debug: Log.d(TAG, "URL Visited: " + url + "\n"); } } } 

To register the ContentObserver I use:

browserObserver = new BrowserObserver(new Handler()); getContentResolver().registerContentObserver(Browser.BOOKMARKS_URI, true, browserObserver); 

And to unregister it:

getContentResolver().unregisterContentObserver(browserObserver); 

This works. However, in this way, I can analyze the URLs only after the browser has loaded them.

Now, is there a way to retrieve the URLs before the browser actually loads them in Android?
