    <p>First, you need to decide whether your app <strong>must have</strong> BBM, or if it can still run without BBM, in some <em>degraded</em> mode (fewer features). It sounds like your app <em>can</em> run without BBM, so I'll address that scenario:</p> <p>Take a look <a href="http://supportforums.blackberry.com/t5/Java-Development/Alternative-BBM-Dependency-checker/ta-p/1491425" rel="nofollow">a this documentation and sample code from R. Masroor on BlackBerry.com</a>.</p> <p>From the description (<strong>bold</strong> is mine):</p> <blockquote> <p>The RIM supplied BBM dependency checker samples, provide two approaches to integrating with BBM. </p> <p>a) The <strong>proxy</strong> method which is appropriate when the application will not run without BBM – it directs the user to download BBM. </p> <p>b) By contrast, the <strong>interface</strong> method provides a way for an application to isolate itself from the BBM, so that the application can still run even if BBM is not installed.</p> <p>Why is this isolation needed? Because if a cod (project) references any BBM methods, then BBM must on the device and at a suitable level before that cod can be loaded. So if an application directly references BBM and there is no BBM (or no suitable level of BBM) on the device, the application will not run. </p> <p>Of the two approaches, <strong>the interface approach is probably the most useful</strong>, as most applications have functionality without BBM. But this approach has two disadvantages:</p> <p>• It requires a start up process to register the <code>RuntimeStore</code> Object </p> <p>• The layered approach and the use of call-backs makes this quite complicated for me.</p> <p>The attached project demonstrates a variation on the interface method, that creates the interface object at Application start-up, using <code>class.forName()</code>. Aside from this change, the sample provided is similar to the interface method, and is explained below. After the explanation of the attached project, this document explains how to create a different structure which you may find easier to work with.</p> </blockquote> <p>Also, for reference, you can take a look at the <code>BBMSDKDemoProxy</code> sample project that comes with the <a href="http://developer.blackberry.com/java/documentation/system_requirements_1396916_11.html" rel="nofollow">BBM SDK download</a>.</p>

    1. COHi Nate, thank you for the answers. They are always helpful. The linked examples make sense, but I'm not quite sure how I'd go about packaging applications together. It seems to me both of those approaches require it. I have not been able to find an answer on the web. Any advice?

    2. CO@Turdnugget, packaging multiple **applications** together, or packaging an **application** along with another **library**? This was a month ago, so I'm a little fuzzy now, but I thought this solution involved using a BBM interface *library*. Are you asking how to package this library with your application?

    3. COSorry for the timelapse, the project is nearing an end and I want to make sure I can deploy as intended. I chose to use a proxy method. So a proxy app is launched, detects if bbm is present on the device. If so it launches the intended app. I would like to know how to package the application, and the proxy application together. So that the user doesn't need to download them separately.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
