Hello All,
\nHope you’re enjoying the world around you.<\/p>\n
Surprised?? I know; after a long time, I am here writing a tutorial on BlackBerry application development. It is a requested tutorial, asked for by some developers a few days back. So here it is:<\/p>\n
<\/p>\n
Note:<\/strong> This tutorial is a part of a series of my tutorials on BlackBerry application development; so far we have discussed the following.<\/p>\n Introduction:<\/strong> The solution is Web Icon. <\/em>How? \u00a0I’m telling you next. First bring a cup of coffee or tea, whatever you like; I brought a cup of Qehwa (a local drink for winters) with two chocolates. Bryan adams is playing in background. Sit relax.<\/p>\n Here we go. A web icon is an application that launches a BlackBerry smartphone browser to a predefined web address. Web icons displayed in the list of BlackBerry smartphone applications and they can be used as shortcuts to a BlackBerry smartphone user’s favorite websites.<\/p>\n Lets start. The first thing is to create a new class that extends from WebIcon. Here I’m dividing talk in two parts; Frist for the devices earlier to 4.0 and second, the part is for 4.1 and later.<\/p>\n 1. BlackBerry Device Software earlier than 4.0<\/strong><\/p>\n When using BlackBerry Device Software versions earlier than 4.0, the default browser is the only one that can be invoked;<\/p>\n As an example, a new class called\u00a0 2. BlackBerry Device Software 4.0 and later<\/strong><\/p>\n The previous sample can also be used for BlackBerry Device Software up to and including 4.2.1, although the following code samples offer a simpler methodology for allowing the web icon to invoke the default browser or invoke specific browsers on the BlackBerry smartphone.<\/p>\n A web icon may invoke either the default browser on the BlackBerry smartphone or the Internet Browser, the Wireless Application Protocol (WAP) Browser, the BlackBerry\u00ae Browser, the Wi-Fi\u00ae Browser, or the BlackBerry\u00ae Unite!\u2122 Browser.<\/p>\n The following code creates a web icon that launches a browser to a specific web address for the given browser type; \u00a0If the given browser type is not available, the web icon launches the default browser.<\/p>\n Note: <\/strong>The previous code sample makes static calls to a factory class called\u00a0 As an example, a new class called\u00a0\n
\nMy friend has a problem: He visits a site many times a day. Every time he has to open browser, type the site name or chose from favorites to see it. He asked, what if there is an icon on my home screen that directly open a browser and navigate to that particular site?” By doing this, i need just one tap, just one. <\/em><\/p>\n![\"\"](\"https:\/\/AasimNaseem.com\/wp-content\/uploads\/2011\/02\/2.png\")
<\/a><\/p>\nBlackBerryWebIcon<\/code> is created below that extends\u00a0WebIcon<\/code> and points to my blog, AasimNaseem.com;<\/a> only three lines of code need to be added to the main<\/code> method of this new class.<\/p>\n![\"\"](\"https:\/\/AasimNaseem.com\/wp-content\/uploads\/2011\/02\/screen-shot-2011-02-23-at-1-21-32-am.png\")

<\/a><\/p>\nBrowserSessionFactory<\/code> to create these different\u00a0 BrowserSessions; <\/code>One thing more ist that BlackBerry Device Software 4.2 may prevent the previous code sample from opening the default browser. As a workaround, add the following code after the call to the displayPage<\/code> method: This issue was resolved in BlackBerry Device Software 4.2.1;<\/p>\n![\"\"](\"https:\/\/AasimNaseem.com\/wp-content\/uploads\/2011\/02\/screen-shot-2011-02-23-at-1-37-08-am.png\")
<\/a><\/p>\nBlackBerryWebIcon<\/code> is created in the following sample that extendsWebIcon<\/code> and points to my blog, AasimNaseem.com;<\/a>. Again, only three lines of code need to be added to this new class.<\/p>\n
