11 Task Server Application Design 11

12 Task Server Application Design (Real Life Example) 12 Requirements Allows a mobile worker to review their tasks wirelessly Must keep the user up-to-date and informed as new tasks created Requires functionality when the handheld is out of coverage Connects into existing Task Management Server via HTTP

13 13 Application Design Task Server Application Example: Task Server Application Components HTTP(S) Client Application Client Application BlackBerry Enterprise Server with BlackBerry MDS Task Manager Server Developed in Java using Java ME and Enhanced BlackBerry APIs Able to persistently store data Able to receive PUSH data from the server (using HTTP) Able to parse incoming Data Application reliability mode to accept input Existing Task Management System

14 Application Design Task Server Application 14 Example: Task Server Application Components HTTP(S) Client Application BlackBerry Enterprise Server with BlackBerry MDS Task Manager Server Existing Task Management System MDS Gateway (No Development Required) Acts as an IP Proxy, Allowing the Application to use standard HTTP for communication Allows the Server to send Server Initiated PUSH messages to the application on the handheld

15 Application Design Task Server Application 15 Example: Task Server Application Components HTTP(S) Client Application BlackBerry Enterprise Server with BlackBerry MDS Task Manager Server Existing Task Management System Server Application Connects into Existing Task Management System Manages Users Performs PUSH Based on changes to the Task Data Reliable Delivery posts the ACK to application URL Manages the PUSH acknowledgement

16 Application Design Task Server Application 16 Example: Task Server Application Components HTTP(S) Client Application BlackBerry Enterprise Server with BlackBerry MDS Task Manager Server Existing Task Management System Existing System (No Development Required) Holds the Users Task Information Provides the Existing System

17 Customized Applications - Device Policy 17 Assign Device Policies to users or groups Control users ability to discover install and remove MDS Studio Applications Allow or deny unsigned applications Control whether applications can access device data Configure storage capacity for application messages

18 Customized Applications Control via Software Configuration Tool 18 Used to control applications Deployment Access Prevent unwanted applications Control Application Access to APIs Phone Addressbook Etc

19 Introduction to developing for GPS & Bluetooth 19

20 BlackBerry and Bluetooth Compatibility 20 Bluetooth is key to Research In Motion s (RIM) peripheral strategy.blackberry devices support the following profiles: Handset Profile (Voice) Hands Free Profile (Voice) Serial Port Profile (Data)

21 Bluetooth 3 rd Party Peripheral Overview 21 Bluetooth support vastly increased number of peripherals available for the BlackBerry Driver development required for usage of peripheral through APIs: Connector.open (similar to JSR 82 interface) net.rim.device.api.bluetooth APIs Device Software Profiles Development APIs v3.8 to v4.1 SPP Required net.rim.device.api.bl uetooth Connector.open

22 Bluetooth Barcode Scanners 22 Provide wireless data capture solutions for mobile workers Seamless integration with the BlackBerry device Small, durable handheld units Leverage BlackBerry device for access to UPC database

23 What is GPS? 23 Global Positioning System - a series of 24 geosynchronous satellites that continually transmit position information Enabling technology for a variety of Location Based Services and applications Navigation and Directions Tracking Reporting GPS Satellites

24 GPS Fix Types 24 Three types of GPS fixes Cellsite Uses cellular towers to attempt to provide triangulated GPS information Least Accurate Information with fastest first fix time Assisted Leverages network access to narrow down possible GPS satellite locations Accurate GPS information in a short amount of time (10 sec) Requires carrier network support Autonomous (Stand Alone) Communicates directly with GPS satellites to provide most accurate fixes Longest time to first fix of all types (~ 2 min)

25 GPS APIs: BlackBerry Support 25 BlackBerry supports JSR 179: Location API for Java ME TM Supported on iden (BlackBerry 7100i and BlackBerry 7520 ) Bluetooth GPS Peripheral Support

26 GPS APIs: JSR 179 Overview 26 javax.microedition.location package Criteria: The criteria used for the selection of the location provider is defined by the values in this class. LocationProvider: This is the starting point for applications using this API and represents a source of the location information. Location: The Location class represents the standard set of basic location information. LocationListener The LocationListener represents a listener that receives events associated with a particular LocationProvider. ProximityListener: This interface represents a listener to events associated with detecting proximity to some registered coordinates.

27 GPS APIs: Opportunities & Sample Use-Cases 27 Enterprise: Fleet Tracking (Transportation) Field Service Employee and Job Tracking Navigational Assistance Consumer: Traffic Information Driving Directions Enhanced 411 Directory/Information Personal Location and Directions Location-Based Content Services
