showBBMAppOptionsAndRegister next which will prompt the user to reconnect the

application to BBM after we finish with the registerApplication function.

 The next step that is required in the registerApplication function is to actually register the

application. We can do this by adding the following lines of code to the end of the

registerApplication function:

//Register the application

try {

blackberry.bbm.platform.register({

// TODO You must define your own UUID

uuid: "uuid"

});

} catch (e) {

alert("You must define your own UUID.");

}

 You’ll notice that we have a UUID field when we register. A UUID is basically a unique

identifier for the application. You’ll need to generate you own UUID to register the

application. An online UUID generator can be found here:

http://www.guidgenerator.com/online-guid-generator.aspx

 Once generated, your UUID string should look something like: uuid: "707968e9-

ae6d-4dbb-b0f5-058a08df8275".

 Finally, add a call to the registerApplication function in the setupApplication function

after the call to the setupMenuItems function. The reason we do not place the call to

we call any BBM API related functions, such as

blackberry.bbm.platform.self.profilebox.clearItems(); which is at the end

of the setupApplication function.

 Now let’s add the function to reconnect to BBM in case the connection fails for any

reason. You may remember we said the function would be called

showBBMAppOptionsAndRegister. Let’s create it now. Add the following function to

your JavaScript code.

function showBBMAppOptionsAndRegister()

{

blackberry.bbm.platform.showBBMAppOptions(function ()

{

registerApplication();

});

}

 This function will show a window allowing the user edit the BBM options for the

application. After the window closes, the registerApplication function will be called.

 Another function we’ll need to add is the getStatusMessage function. If an error occurs,

there is an associated reason. This function will change the error code into a reason the

user can understand.
