2. Blackberry Tips and Tricks
• *#06# for IMEI

new text – C, N for next day email, P for previous, R for reply to, L reply all

3. What is JAVA?
JAVA is:
• A popular Nairobi coffee house.. But that is
not the Java we want…
• Java is an OO Programming Language. Object
Oriented. Tries to use fewest-implementation
dependencies as possible

4. What JAVA is on the Blackberry
Everything. All BBs have JVM to
run scripts and .. Stuff.
…well most things 
First J2Me App experience w/ OS v. 7. I broke my
Blackberry JVM i.e. nuked it and then
restored. Bottom line: if Java doesn’t work on
it, few others will

5. What Java can achieve
• JAVA is Huge..(Libraries, Language Support)
• JAVA is Good.. (Strict OOP, JVM, Easy User Interface)
• Practice WORA (Write Once, Run Everywhere)
• Java is a middle-ground between the difficult C/C++
code, and the inability of HTML5 to access assets

6. Point to NOTE
• BUILD FOR EVERYONE - An application built in BlackBerry JDE 6.0
runs on a BlackBerry smartphones running BlackBerry Device Software
6.0 and later. It DOES NOT RUN on a BlackBerry smartphones running
BlackBerry Device Software 5.0 and prior. Thus, when building
applications, YOU SHOULD USE A BLACKBERRY JDE VERSION THAT
MATCHES THE LOWEST VERSION OF BLACKBERRY DEVICE SOFTWARE
YOU WANT TO SUPPORT.

7. What do you need to start?
• The Java Blackberry SDK (JDE v7.1) (has the BlackBerry
simulator, a BlackBerry MDS simulator, and profiling tools for building and
testing BlackBerry Java apps. MDS SIM is used to test network, push HTTP,
and browser applications that are designed for use with a BlackBerry
Enterprise Server.) – 296mb
• SDK 7.1 went away on a trip.. She may not be coming
back; Get the Eclipse Plugin – 519mb
• Simulator and Debugger – (BB10 - 400mb, OS v7 –
246mb
• Learning resources in GitHub

8. Publishing your Stuff!

9. Interpreting the DATA
1. Post your App on AppWorld 4free (they don’t charge you like
everyone else does) MS – $49, Apple - $99, Chrome – 25$
2. Ads in your App (little revenue) – you need to install the AS
SDK which is <1mb download and create an account
3. Charge for the App (higher levels) – you need to install the
PS SDK which shouldn’t be too hard
4. No operator billing yet – hard to buy Apps directly from
mobile money

10. You need to visit

more information.
