What is new in MIDP3.0? Enhanced LCDUI LIBlets - Shared code between MIDlets Concurrency - Execute more that one MIDlet at same time Application and System Events Inter MIDlet Communication - IMC Application Level Access Control - APLAC Screen Saver MIDlet Auto Start & Controlling User actions on MIDlets Provisioning Record Stores - OTA RMS
MIDP3.0 JSR 271 Expert group formed in March 2005 Expert Group Lead by Mike Milikich from Motorola Over 100 members including: Device Manufacturers Network Operators Application & Content Developers VM Vendors
MIDP3.0 Release date Final Approved Version Expected Q2-2008
MIDP3.0 LCDUI ¨C High Level Custom layout support: Application controls Layout of items in a Form Flow and Table Layout Commands Improved placement control Sub ¨C Commands Icons Tabbed Panes ¨C each pane contains a Screen Idle Item support Image Item to support GIF / animated GIF
MIDP3.0 LCDUI ¨C Low Level Support for multiple Displays and orientations Alpha blending Image enhancements Animated Images Transparent mutable Images Scaling and rotation Application-provided Fonts Splash screens
LIBlets Shareable components that one or many midlets can use Expose a set of API¡¯s and resources that a MIDlet can use Inert code and resource fragments that only execute within a MIDlet context. Save static footprint size by preventing LIBlet code packaged in each MIDlet. Potentially reduce download times for applications
LIBlets LIBlet code does not execute by itself LIBlet is executed in the MIDlet¡¯s execution enviroment A binding: act of loading a MIDlet with all associated LIBlets into a single execution enviroment. Jars are all in the classpath
Concurrency Multiple MIDlets: AMS provides a means to launch multiple applications MIDlets in the background, not visible to the user Auto Start MIDlets Screen Saves MIDlets
Application and System Events MIDlets can generate applicatino events MIDlets can listen to System events Battery power on/off idle event Push registration on events: Application launch on event launch application on flip/close
Inter MIDlet Communication (IMC) Communication between multiple running MIDlets Low-level bi-directional stream connection within the device GCF based ¨C Connector.open(¡°imc://...¡±); An IMC Server is created with a name, and the client tries to connect to this named service. MIDlet A IMCConnection MIDlet B IMCServerConnection
APLAC Application Level Access Control (APLAC) MIDlets interact via Events, IMC, RMS Restrinct interactions based on Domain Signer Vendor E.g. Share a record store only with MIDlets that are developed by a specific Vendor
