When you add widgets to the Home screen, most widgets are already a predetermined size and shape. Either they fit in the space given or they do not. If you long-click a widget, you can move it within a screen, but you cannot make it larger or smaller. If you have a choice of widgets, you ll find that many app developers label the widgets with things like 3 2 or 4 1. What does that mean If you measure your phone s screen not by the physical screen size, but by the number of apps you can store on it, most phones have a Home screen that measures four app icons by four app icons. The widget measurement generally goes horizontally by vertically, so a widget that measures 4 1, such as the Power Control widget (shown at the top of the screen in Figure 17 1), takes up the space of four apps across and one down. This allows you better Home screen space management.

The better approach is to use the HTTP Validation model. This model sends each response with a ticket that references the uniqueness of the data. If the client wants to download the content again, the client sends the server a ticket from the last download. The server compares the sent ticket with the ticket that it has; if the server notices the tickets are identical, it sends an HTTP 304 to indicate no changes have occurred. At that point, the client can retrieve the old content from the cache and present it to the user as the latest and greatest. The HTTP Validation

model still requires an HTTP request, but does not include the cost of generating and sending the content again. In terms of an HTTP conversation, the HTTP Validation model is implemented as follows. This example illustrates a request from a client and the response from the server. Request 1: GET /ajax/chap04/cachedpage.html HTTP/1.1 Accept: */* Accept-Language: en-ca Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 2.0.50215) Host: 127.0.0.1:8081 Connection: Keep-Alive Response 1: HTTP/1.1 200 OK ETag: W/"45-1123668584000" Last-Modified: Wed, 10 Aug 2005 10:09:44 GMT Content-Type: text/html Content-Length: 45 Date: Wed, 10 Aug 2005 10:11:54 GMT E B V N Server: Apache-Coyote/1.1 <html> <body> Cached content </body> </html> The client makes a request for the document /ajax/chap04/cachedpage.html. The server responds with the content, but there is no Cache-Control nor Expires identifier. This seems to indicate that the returned content is not cached, but that is not true. The server has indicated that it is using the HTTP Validation model, and not the HTTP Expiration model. The page that is returned has become part of a cache identified by the unique ETag identifier. The ETag identifier, called an entity tag, could be compared to a unique hash code for an HTML page. The letter W that is prefixed to the entity tag identifier means that the page is a weak reference and the HTTP server may not immediately reflect updates to the page on the server side. The next step is to refresh the browser and ask for the same page again. The HTTP conversation is illustrated as follows. Request 2: GET /ajax/chap04/cachedpage.html HTTP/1.1 Accept: */* Accept-Language: en-ca Accept-Encoding: gzip, deflate If-Modified-Since: Wed, 10 Aug 2005 10:09:44 GMT If-None-Match: W/"45-1123668584000"

If you want to give your phone a complete makeover, you can use one of many Home replacement themes. Most themes at this time are written for Android 1.5 and 1.6, and are designed to run using a specialized app that acts as a theme engine. They replace your standard Home screen and sometimes modify the appearance of the icons used to launch your apps. You could turn all of your icons into spaceships, sports icons, or cartoon figures with a matching background. Popular theme engines include Freshface (shown in Figure 17 2) for G1 and MyTouch phones, aHome, Open Home, and Panda Home. The disadvantage of running a Home replacement theme is that it is essentially running an app all the time. That means it may drain your battery faster or make your phone crash more often. Be sure to check out the comments in the Android Market before downloading a new theme.
