Before Getting Started

Workshop

8 weeks 1 day/week 3 hours/day Total= (8*1*3)=24 hours Every Tuesday (2:30 PM)

Time Duration: Place:

So title of this workshop could be:Android in 24 hours!!!

Please read this:http://norvig.com/21-days.html

Before Proceeding Any Further

Prerequisite: Working knowledge inJava Programming language

* Object Oriented Programming:* What are the advantages?

* Why Java knowledge is the prerequisite?

* I hate to program in Java, what should I do?

* Why Google chose Java for Android?

Before Introduction:1. Monotonous discussion should be banned

Before Introduction: Your Suggestions2. 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. Workshops2. Training Programs 3. Bootcamps4. Onsite Contests with help from experienced Developers5. Idea-based Contests with help from experienced Developers6. Jamming Events7. Open source projects

Depends on your feedback

Before Introduction: Your Suggestions3. 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.

Before Introduction: Your Suggestions5. 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)

Before Introduction: Your Suggestions7. 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

So Today…

1. Get Basic Idea on Mobile and Smartphone Applications2. Get Basic Idea on Mobile, Smartphone & Tablet Platforms3. Identify the Position of Android Platform4. Background and History of Android5. Get the Idea: Why Should We Learn Android Platform6. Opportunities7. Some App Demos8. System Architecture9. Environment Setup to Kick-start10. Development Environment11. Application Structure

Mobile and Smartphone ApplicationsSmart 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
