The achievement of newer BlackBerry versions such as the Pearl, Curve, Daring and Storm have permitted RIM (Analysis in Movement) to penetrate the consumer smartphone promote and go head-to-head with the Apple iPhone being an application platform. If you've got been ignoring the BlackBerry platform simply because it absolutely was far too Enterprise-focused on your apps, it might be time for you to especially goal the BlackBerry. Here's the way you get rolling. It can be Java Time BlackBerry advancement for all recent versions is finished solely in Java. So in case you are not a powerful Java programmer, now's enough time to brush up on your Java programming techniques. (C# programmers will find the changeover to Java relatively uncomplicated, the languages are very close in many respects.) Really don't understand with regards to the latest Java options, nevertheless, since the BlackBerry platform is made on prime of Java Micro Edition (Java ME), which is alone a derivative of Java edition 1.3. So neglect all the fancy (but practical) language options released in Java 1.five -- generics, enumerations, and so forth -- you cannot use these in BlackBerry programming. You cannot also use a lot of the library courses you might be familiar with -- they're just not there. A little subset in the Java Standard Edition (Java SE) courses are supported, as well as a range of BlackBerry-specific courses. Java Micro Edition? As soon as you've got brushed up on your Java, you'll want to spend a little of time realizing the Java ME platform, which was formerly referred to as Java two Micro Edition, or J2ME for brief. You should have an understanding of the concepts of configurations and profiles, and in particular the CLDC and MIDP criteria. You will find heaps of information about these in many publications and on Sun's Java advancement web page. The BlackBerry Platform Immediately after learning about Java ME, it really is time for you to examine the BlackBerry platform. The BlackBerry platform is determined by the CLDC and features aid for MIDP two.0. Nonetheless, a lot of BlackBerry-specific courses may also be supplied. Which brings you towards the 1st concern you may encounter: are you likely to jot down a BlackBerry application or perhaps a MIDP application? In the MIDP application you might be constrained to only make use of the APIs exposed by CLDC and MIDP criteria. Your application will operate over the BlackBerry and on most cellphones, but it would not find a way to implement any in the BlackBerry's exclusive options. You'll be able to use any MIDP-compatible advancement device, like the Sun Java Wireless Toolkit for CLDC (formerly referred to as the J2ME Wireless Toolkit), to produce your apps. Most application builders choose to construct BlackBerry-specific apps. This implies learning the BlackBerry-specific APIs -- such as new person interface courses -- and making use of the BlackBerry Java Growth Environment (JDE) to create your apps. The JDE, which is free of charge to get|acquire, functions with the normal Java Application Growth Kit and delivers you with all the resources necessary to generate, deal, examination and debug BlackBerry apps. You don't even want a BlackBerry handheld, since the JDE includes a full-featured BlackBerry machine simulator. A total list of JavaDocs is supplied that describes all the courses and interfaces accessible to programmers. Immediately after installing and adding the JDE, you may need to read the developer's guides that come with the JDE and examine the sample apps which might be shipped with it. Then begin your advancement by composing some uncomplicated apps to get a come to feel for that BlackBerry APIs as well as the resources. Obtain a BlackBerry Handheld While you can produce and examination your apps at no cost, at some time you'll need to operate the application on an exact BlackBerry handheld. This may run you money, needless to say, and so it really is not some thing you may need to do right up until you might be serious about composing BlackBerry apps. On-device testing is vital to making certain which the application functions properly, since the simulator is just not an excellent emulation process. In case you are truly serious about BlackBerry application advancement, take into account also signing up for on the list of BlackBerry developer applications for added aid and early entry to new devices and APIs. It is best to also examine RIM's other BlackBerry developer assets. In addition there are third-party community forums and publications accessible to help you you understand the BlackBerry platform. Summary BlackBerry programming is just not tricky if you know some Java and you simply have an understanding of the constraints and limits in the underlying Java ME platform. You've to discover a brand new list of APIs and use new advancement resources, but from the close it really is just yet another form of Java programming.
