Application Programming Interface. A set of classes used by programmers to write applications, which provide standard methods and interfaces and eliminate the need for programmers to reinvent commonly used code.
Application Management Service. The system functionality that completes tasks such as installing applications, updating applications, and switching foregrounds.
The screen that lists all of the installed applications. The user gets to this screen by pressing the Apps soft key on the home screen. The application list uses text color to show which applications are running. It also provides a system menu that enables the user to perform application management tasks on the highlighted application.
An application state in which the application does not receive events from its input stream and its displayable is not rendered to the screen.
Connected Device Configuration. A Java ME platform configuration for devices, it requires a minimum of 2 megabytes of memory and a network connection that is always on.
Connected Limited Device Configuration. A Java ME platform configuration for devices with less than 512KB of RAM and an intermittent (limited) network connection, it uses a stripped-down Java virtual machine called the KVM, as well as several minimalist Java platform APIs for application services.
Defines the minimum Java runtime environment (for example, the combination of a Java virtual machine and a core set of Java platform APIs) for a family of Java platform ME devices.
The application state in which the application is rendered to the device display and the input stream is passed to it.
Changing which application is in the foreground by shifting the focus from one application to another.
Generic Connection Framework. A part of CLDC, it improves network connectivity for wireless devices.
The main screen of the application manager. This is the screen the user sees after they exit an application.
HyperText Transfer Protocol. The most commonly used Internet protocol, based on TCP/IP, which is used to fetch documents and other hypertext objects from remote hosts.
Secure HyperText Transfer Protocol. A protocol for transferring encrypted hypertext data using Secure Socket Layer (SSL) technology.
Java Application Descriptor file. A file provided in a MIDlet suite that contains attributes used by application management software (AMS) to manage the MIDlet's life cycle, as well as other application-specific attributes used by the MIDlet suite itself.
Java Archive file. A platform-independent file format that aggregates many files into one. Multiple applications written in the Java programming language and their required components (.class files, images, sounds, and other resource files) can be bundled in a JAR file and provided as part of a MIDlet suite.
Java Community ProcessTM (JCPTM) program
Java Community Process program. An open organization of international developers and licensees who develop and revise Java platform specifications, reference implementations, and technology compatibility kits using a formal submission and approval process.
Java Platform, Micro Edition. A group of specifications and technologies that pertain to running the Java platform on small devices, such as cell phones, pagers, PDAs, and set-top boxes. More specifically, the Java ME platform consists of a configuration (such as CLDC or CDC) and a profile (such as MIDP or Personal Basis Profile) tailored to a specific class of device.
Java Specification Request (JSR)
A proposal for developing new Java platform technology, which is reviewed, developed, and finalized into a formal specification by the JCP program.
A software "execution engine" that safely and compatibly executes the byte codes in Java class files on a microprocessor.
A Java virtual machine designed to run in small devices, such as cell phones and pagers. The CLDC configuration is designed to run in a KVM.
Liquid Crystal Display. A common kind of screen display often used in small devices.
Liquid Crystal Display User Interface. A user interface toolkit for interacting with LCD screens in small devices. More generally, a shorthand way of referring to the MIDP user interface APIs.
An application written for MIDP.
A way of packaging one or more midlets for easy distribution and use. Each MIDlet suite contains an application descriptor file (.jad), which lists the class names and files names for each MIDlet, and a Java archive file (.jar), which contains the class files and resource files for each MIDlet.
Mobile Information Device Profile. A specification for a Java ME technology profile, running on top of a CLDC configuration, which provides APIs for application life cycle, user interface, networking, and persistent storage in small devices.
A technique used to complicate code by making it harder to understand when it is de-compiled. Obfuscation makes it harder to reverse-engineer applications and therefore, steal them.
A set of Java ME technology APIs that provides additional functionality by extending the runtime capabilities of an existing configuration and profile.
Portable Network Graphics. An image format commonly used with MIDP that can be compressed, transmitted, and stored without losing image quality.
Taking a resource, such as the foreground, from another application.
Due to limited memory and processing power on small devices, the process of verifying Java classes is split into two parts. The first part is preverification and done off-device using the preverify tool. The second part, which is verification, is done on the device at runtime.
A set of APIs added to a configuration to support specific uses of a mobile device. Along with its underlying configuration, a profile defines a complete and self-contained application environment.
A mechanism for providing services, data, or both to a mobile device over a network.
The list of inbound connections, across which entities can push data, maintained by the Java Wireless Client for Multitasking software. Each item in the list contains the URL (protocol, host, and port) for the connection, the entity permitted to push data through the connection, and the application that receives the connection.
Remote Method Invocation. A feature of Java SE technology that enables Java platform objects running in one virtual machine to seamlessly invoke objects running in another virtual machine.
Record Management System. A simple record-oriented database that enables a MIDlet to persistently store information and retrieve it later. MIDlets can also use the RMS to share data.
Short Message Service. A protocol allowing transmission of short text-based messages over a wireless network.
Simple Object Access Protocol. An XML-based protocol that allows objects of any type to communicate in a distributed environment, it is most commonly used to develop web services.
Secure Sockets Layer. A protocol for transmitting data over the Internet using encryption and authentication, including the use of digital certificates and both public and private keys.
A set of Java programming language tests developed specifically for the wireless marketplace, providing targeted, standardized testing for CLDC and MIDP on small and handheld devices.
Single Virtual Machine. A mode of the Java Wireless Client for Multitasking software, it can run only one MIDlet at a time.
At the platform level, each separate application that runs within a single Java virtual machine is called a task. The API used to instantiate each task is a stripped-down version of the Isolate API defined in JSR 121. See the CLDC HotSpot Implementation Architecture Guide for more information.
Transmission Control Protocol/Internet Protocol. A fundamental Internet protocol that provides for reliable delivery of streams of data from one host to another.
Wireless Application Environment. It provides an application framework for small devices, by leveraging other technologies such as WAP, WTP, and WSP.
Wireless Application Protocol. A protocol for transmitting data between a server and a client (such as a cell phone) over a wireless network. WAP in the wireless world is analogous to HTTP in the World Wide Web.
Wireless Messaging API. A set of classes for sending and receiving Short Message Service messages.
The button the user presses to end a task. On a real device this is the End key. On Windows it is the End key and sometimes the power key on the phone skin.
