It is expected to become available in March. Through a partnership announced Tuesday with PayPal, buyers will be able to use the popular online payment service at the store. The company wants to prevent developers from creating applications for the Storefront, only to find out at the last minute that they don't meet RIM's conditions.
Apple has come under fire for allegedly removing applications from the App Store based on policies that weren't clear. The expanded development and delivery options come as RIM focuses on extending its powerful brand from the enterprise world to consumers. Demonstrations at the event on Tuesday leaned heavily toward the consumer side, including the Gameday baseball news application from Major League Baseball's MLB.
Other moves announced Tuesday that should make life easier for developers included a bug-tracking database and new beta-test versions of plug-ins for the Eclipse and Visual Studio development environments. Several developers at the conference welcomed the ability to write BlackBerry applications with Eclipse, the open-source development platform. One attendee, a senior software engineer at a research institution in California, said the ability to write for the BlackBerry using Eclipse, Visual Studio or Java would give him more flexibility in assigning developers on his team to work on BlackBerry applications for internal use.
For more information on the Java Plug-in v1. For more information on the Java SDK v5. To learn more about the range of products and services available to the BlackBerry developer community, please visit www. Any applications that make use of particular features and corresponding APIs will only run on a device that supports the feature. A BlackBerry Java application is tied to the minimum BlackBerry Device Software version for which it was created; it will not run on a device running any previous version of the BlackBerry Device Software.
This update also affects the online help and the code-completion capabilities in an Integrated Development Environment IDE , the device simulators, and more.
Running an application crafted for a particular BlackBerry Device Software version on an earlier version is not supported and should not be attempted. Because each version of the BlackBerry Device Software has its own special version of the development tools, if you are developing applications for multiple BlackBerry Device Software versions, you have to install multiple versions of the tools.
RIM offers different development tools for Java developers, and the good news is that all of them are free. The only exception to this is the cost an organization incurs when purchasing a set of signing keys, as described later in this chapter. The one you select will vary, depending on your preference for IDE. The available options are. The tools are also useful to developers who want to build automated processes for building or manipulating applications outside of an IDE.
When the page opens, look for a section on Java Development Tools. Depending on your selection, a different set of options appears.
Pay special attention to the system requirements for each tool. When downloading the JDE or BlackBerry JDE Component Package, scroll down the page until you locate a section of the page containing the links to download the specific versions of the tools. Select the appropriate downloads for your particular needs. Note - The BlackBerry MDS simulator is required to test BlackBerry applications using the device simulators that make use of network connections to access a remote server.
For some reason, the 4. If working in conjunction with other JDE versions, the 4. In this case, a full installer includes the editor components and associated files plus one of the eJDE Component Packs version 4.
If you need to support building or maintaining applications for additional BlackBerry Device Software versions, you will likely want to download additional eJDE Component Packages one for each version of the BlackBerry Device Software being supported. After the files are extracted, launch the Eclipse IDE and complete the following steps:. If you downloaded additional component packages, repeat the process for each of the additional component packages you want to use with this instance of Eclipse.
North American users can use the BlackBerry Eclipse update site to download and install component packages directly into an existing Eclipse installation.
Eclipse connects to the BlackBerry Eclipse Update site and retrieves a list of the components available for installation, as shown in Figure Select the component that you want to install and click the Install button to download and install the selected component s. Chances are that most developer will find themselves needing to use one of the controlled APIs described in Chapter Subsequent chapters show how to sign an application in the different Java development tools, but now, it seems to be a good time to discuss how to get a copy of the signing keys needed to sign an application.
BlackBerry applications that use controlled APIs do not run on BlackBerry devices until they are signed with the appropriate keys. The applications run in the BlackBerry simulators, so it is possible to build and test applications without the appropriate keys. Depending on the types of controlled APIs your application uses, you might need different sets of keys.
If your applications use any of the Certicom cryptography APIs, there is a separate process to secure a license from them. No, you purchase one set of keys per PC, and you can sign as many applications as you want.
