Survey Review

Let’s see what you said…

I am expecting to learn in this course Pervasive and ubiquitous computing principles Capabilities, inner workings and limitations of mobile devices Applications for mobile devices Mobile/wireless network standards Developing mobile applications for latest devices Fundamentals of wireless embedded devices Mobile system design principles Interface design, ergonomics and human factors State of the art in mobile devices and standards Future of this domain What are the challenges hindering evolution of mobile devices Security issues How to improve health (and in general) life with these technologies

My concerns about this course are What’s more than what I already know Not enough collaboration with fellow students (x2) Language limitations Might not count toward my credit hours Too much workload (x2) Too much or too advanced programming required

and too little learning (x2) Not adequate background (x2) Not practical or application-oriented

Therefore…my wishes for this course are Teach me more than what I already know Apply some collaborative learning Be easy to understand Count toward my degree requirements Have reasonable workload Require not too much programming Require little background knowledge Be practical and application-oriented

Android: Background history

In July 2005, Google acquired Android, Inc., a small company that developed software for mobile phones

In the following months, the former “Android, Inc.” team started working on a Linux-based OS for mobile devices

By the end of 2006, media and press was filled with news about Google entering the mobile market.

In November 2007, the Open Handset Alliance was announced.

OHA’s first project: Android.

Open Handset Alliance:Mission statement Building a better phone for consumers

Today, there are 1.5 billion television sets in use around the world. 1 billion people are on the Internet. But nearly 3 billion people have a mobile phone, making it one of the world's most successful consumer products. Building a better mobile phone would enrich the lives of countless people across the globe. The Open Handset Alliance™ is a group of mobile and technology leaders who share this vision for changing the mobile experience for consumers.

Innovating in the openEach member of the Open Handset Alliance is strongly committed to greater openness in the mobile ecosystem. Increased openness will enable everyone in our industry to innovate more rapidly and respond better to consumers' demands. Our first joint project as a new Alliance is Android™. Android was built from the ground up with the explicit goal to be the first open, complete, and free platform created specifically for mobile devices.
