3. Before Proceeding Any Further
Prerequisite:
Working knowledge in
Java Programming language
* Object Oriented Programming:
* What are the advantages?
* Why Java knowledge is the
prerequisite?

what should I do?
* Why Google chose Java for Android?

4. Before Introduction:
1. Monotonous discussion should be banned

5. Before Introduction: Your Suggestions
2. This could be the first phase and it should be continued.
According to your feedback, we can arrange the sequels of
this workshop:
(Remember: Terminator 2 was more successful)
1. Workshops
2. Training Programs
3. Bootcamps
4. Onsite Contests with help from experienced Developers
5. Idea-based Contests with help from experienced Developers
6. Jamming Events
7. Open source projects
Depends on your feedback

6. Before Introduction: Your Suggestions
3. You can emphasize on learning OOPs before starting
session on Android. Because very large number of Software
Developer have no clear concept on OOP.
OOP concept is indispensable. But we have to learn in parallel.
4. It might get a little more interesting if the attendants are
allowed to have the opportunity to play or use some of the
android apps themselves.
Can you suggest how can we do that? May be next time we’ll try.
We may review some good apps today.

7. Before Introduction: Your Suggestions
5. If you give us some knowledge regarding to developing
android software and how to post them in the android
market it can be helpful to us in the future.
We’ll do that in this session
6. You can give us some video about mobile application
programming which can help us.
We’ll provide you complete course content with video tutorials
we did in BASIS (Bangladesh Association of Software & Information Services)

8. Before Introduction: Your Suggestions
7. Consider all type of audience.
Excellent suggestion. We’ll try that
8. Discuss from technological perspective as well as business
Excellent suggestion. We’ll try that
9. Forecast about near future associated with Android.
Excellent suggestion. We’ll try that

9. So Today…
1. Get Basic Idea on Mobile and Smartphone Applications
2. Get Basic Idea on Mobile, Smartphone & Tablet Platforms
3. Identify the Position of Android Platform
4. Background and History of Android
5. Get the Idea: Why Should We Learn Android Platform
6. Opportunities
7. Some App Demos
8. System Architecture
9. Environment Setup to Kick-start
10. Development Environment
11. Application Structure

10. Mobile and Smartphone Applications
Smart Phones
1. A smartphone is a mobile phone that
offers more advanced computing
ability, Features and connectivity
than a contemporary mobile phones.
2. Smartphones may be thought of as
handheld computers integrated with a
mobile telephone.
3. They also provide their own Operating
System with Application Development
Framework
