Introduction to the design and implementation of applications for handheld systems, such as smartphones and tablets, running the Android Platform.
Handheld systems, such as smartphones and tablets are now the most common way for people to access and interact with computing services. The demand for application development skills is therefore growing at a breathtaking pace. These skills, however, are multi-‐ faceted, requiring students to master computer science and engineering principles, to learn the details of specific mobile application platforms, and to design artistic and engaging user interfaces that respond to how, where and why handheld applications are used.
This course will cover the fundamental programming principles, software architecture and user experience considerations underlying handheld software applications and their development environments. To bring these concepts alive, the course will involve in-‐depth, hands-‐on examples, implemented in the Android Platform, the fastest growing segment of the handheld system user base. Students will apply these teachings, also using the Android Platform, in laboratory projects and in a large-‐scale semester project.
Note: This course is part of a Coursera Specialization
This course and two others, led respectively by Drs. Douglas Schmidt and Jules White of Vanderbilt University, have been designed to complement each other. Click here to find out more about the Mobile Cloud Computing with Android (MoCCA) Specialization. Therefore, some of the programming assignments and the course project for these courses will be coordinated.
This course focuses on handheld systems and the design of user-facing applications, and will be taught first. The first Vanderbilt University course, Pattern-Oriented Software Architectures: Programming Mobile Services for Android Handheld Systems will focus on systems programming topics, such as middleware services and background processing. The second Vanderbilt University course, Programming Cloud Services for Android Handheld Systems will focus on connecting Android mobile devices to cloud computing and data storage resources, essentially turning a device into an extension of powerful cloud-based services on popular cloud computing platforms, such as Google App Engine and Amazon EC2.
Nevertheless, each of these courses stands alone. Students are not required to take all of them. Those who do, however, will gain a much more detailed, end-to-end understanding of handheld systems and their applications.
Objective: In this lesson, I discuss the Android Platform and the Android Development Environment. By the end of this lesson you should understand the components comprising the Android Platform and be able to use various tools found in the Android Development Environment
• Lecture #1 – The Android Platform
• Lecture #2 – The Android Development Environment
• Lab #1: Setup: Students identify required software & install it on their personal computers. Students perform several tasks to familiarize themselves with the Android Platform and Development Environment.
Objective: In this lesson, I explain the basic components from which all Android applications are created. I also present the Activity class - one of the main class responsible for displaying an application's user interface. By the end of this lesson, you should recognize the four fundamental components of Android applications, be able to create a simple Android application and understand the lifecycle of the Activity class.
• Lecture #3 – Application Fundamentals
• Lecture #4 – The Activity Class
• Lab #2 – The Activity Lifecycle & Reconfiguration: Students build applications that trace the lifecycle callback methods issued by the Android platform and that demonstrate Android's behavior when the device configuration changes (e.g., when the device moves from portrait to landscape mode and back).
Objective: In this lesson, I explain the Intent class and Permissions. I also present the Fragment class - another key class responsible for displaying an application's user interface. By the end of this lesson, you should be able to create applications comprising more than one Activity, understand how to define and enforce permissions and be able to design applications that run on multiple, differently-sized devices.
• Lecture #5 – The Intent Class
• Lecture #6 – Permissions
• Lecture #7 – The Fragment Class
• Lab #3a - Intents & Permissions: Students build applications that require starting multiple Activities via both standard and custom Intents.
• Lab #3b - Permissions: Students build applications that require standard and custom permissions.
• Lab #3c – Multi-pane and single-pane User Interfaces: Students build an application that uses a single code base, but creates different user interfaces depending on a device's screen size.
Objective: In this lesson, I summarize and demonstrate the many class Android provides for creating user interfaces. By the end of this lesson, you should be able to define and deploy applications with sophisticated user interfaces.
• Lectures #8 – User Interface Classes - Part I
• Lectures #9 – User Interface Classes - Part II
• Lab #4 – ToDoManager: Students build a ToDo list manager using the user interface elements discussed in lecture. The application allows users to create new ToDo Items and to display them in a ListView.
• Mini-project - Modern Art User Interfaces: Students will build a complete app from scratch. Collaborators from the Musuem of Modern Art will help student draw some inspiration from the work of several Modern Art masters.
Objective: In this lesson, I dive deeper in Android, focusing on advanced some of the advanced capabilities it provides. I discuss using User Notifications to interact with the user, listening for and responding to events using the BroadcastReceiver class, and handling concurrency with Threads, AsyncTask & Handlers. There are also two optional lectures dealing with using Alarms to run code at pre-scheduled times and with understanding how to access data over the network. By the end of this lesson, you should understand how these key technologies are used to support more advanced Android applications.
• Lecture #10 – User Notifications
• Lecture #11 – The BroadcastReceiver Class
• Lecture #12 – Threads, AsyncTask & Handlers
• Lecture #13 - Alarms
• Lecture #14 - Networking
• Lab #5 – Tweet app: Students build an app that downloads and displays Tweet data. The app uses an AsyncTask for downloading data over the network. The app will also user BroadcastReceivers and User Notifications to apprise the user of the apps behavior and state.
Objective: In this lesson, I present a number of technologies related to presenting and interacting with dynamic content. This includes graphics and animation, handling touch input from the user, and recording and playing multimedia. By the end of this lesson, you should be able to animate your applications, create apps that respond to both standard and custom gestures, and display and use multimedia content.
• Lecture #15 – Graphics & Animation I
• Lecture #16 – Graphics & Animation II
• Lecture #17 – Multi-touch & Gestures
• Lecture #18 – MultiMedia
• Lab #6 - Bubble Popper: Students write an application to display and animate bubbles (graphics that look like bubbles) on the device's screen. When users touch the screen where a bubble is displayed, the bubble pops. The app will also accept gesture input, allowing the user to change the direction and speed of the bubble, using a fling gesture.
Objective: In this lesson, I go over the many sensors that now come standard on most mobile devices. I also provide a focused discussion of using sensors to capture location information and using maps to display that information. By the end of this lesson, you should be able to create context aware applications whose behavior changes based on environmental conditions.
• Lecture #19 – Sensors
• Lecture #20 – Location & Maps
• Lab #7 - Place Badge Collector: Students build an application that uses location information to collect Badges for the places they visit.
Objective: In this lesson, I wrap up with a discussion of some behind the scenes Android capabilities. I discuss how to manage structured data, how to share that data across applications using the ContentProvider class, and how to run operations in the background and across processes using the Service class. By the end of this lesson, you should be able to design complex applications that leverage complex structured data sets and that perform processing in the background.
• Lecture #21 – DataManagement
• Lecture #22 – The ContentProvider Class
• Lecture #23 – The Service Class
• Lab #8 - Place Badge Collector Content Provider: Students build a ContentProvider to store the Place Badges they collect with the app from Weekk 7 application that uses location information to collect Badges for the places they visit.
Mini-project - DailySelfie: Students will build a complete app from scratch. This app will remind users to take a picture of themselves once a day. The app will collect and display the resulting set of photos.
Each lesson will consist of video presentations, logically divided roughly into 5-10 minute sections. Throughout the lecture video there are ungraded "in-video" questions to help ensure that students are understanding the material. Each week there is also a short quiz containing questions/tasks to help ensure that the students have understood that week's lectures.
The in-video questions are related to the current video section, and provide supplementary information, “Food For Thought” discussion, and "FLASHBACK" questions, which challenge the students to think about something we have discussed in a previous lesson.Each week's videos will be accompanied by a lab exercise consisting of an assignment write-up, partially completed source code, and executable test cases. The students will run the test cases on their own computers to determine whether they've successfully completed the lab. For some labs, we will also require students to examine and grade the submissions of other students.
Upon completing this course, students should be able to:
This course assumes that students are comfortable programming in Java and have some experience programming Android apps. If you don't have any significant Java programming background, please look on the Internet for one of the many Java-related
tutorials that are freely-available.
You can preview some of the videos by pressing the "Preview Lectures" Button at the top of the course webpage
For this course, you'll need is an Internet connection, a computer on which to run free Android developer tools, and the time to read, write, and discuss.
How to write the software applications that you and half the world are running on your handheld devices.
Experience with Java should be enough. As mentioned in the Recommended Background Section, those who don't know Java, but have strong familiarity with other languages may want to take a Java tutorial prior to starting this course.
Not really. The main programming language for Android is Java.
There is no course textbook. If you want to get started early, dive into the Android Developer's Website
No. All the graded exercises will be done using the Android Emulator.
This MOOC course and another course tentatively called Pattern-Oriented Software Architectures for Concurrent and Networked Mobile Devices and Clouds, taught by Professors Doug Schmidt and Jules White of Vanderbilt University have been designed to complement each other. In particular, some of the programming assignments and the course project for both courses will be coordinated. The focus of Vanderbilt MOOCs will be systems programming topics, such as server-side Android concurrency, background processing, networking, and computing cloud integration, and will be taught starting in late March 2014. Additional information on our trans-institutional MOOC sequence is available here and here.
No. If you just want to take some of the courses in this sequence--or take them all in different order--you're certainly welcome to do so, and you'll still learn a lot. However, if you take all the courses in this sequence in the order presented you'll gain a deeper, end-to-end understanding of handheld systems, their applications and services, as well as their integration into the cloud.
All the course material (e.g., video lectures, quizzes, short essays, programming assignments, etc.), for each week will be made available at 12:00am eastern time (5am UTC/GMT). each Friday of the course.
I recommend watching the videos multiple times, looking for different levels of meaning in the diagrams and the examples. Likewise, I recommend reading outside sources of information. Naturally, participating in the online discussion forums (and ideally, a meetup group if one is available in your area) will help make the course material more engaging.
All of my videos use Eclipse as Android Studio is still in a pre-release state. If you're using a non-Eclipse development environment, such as AndroidStudio, you may need to enlist the help of other students on the online discussion forum.
Coursera recommends using the Chrome and Firefox browsers. There's also a mobile app for Coursera MOOC, as well.
PDF versions of the slides will be available online as the videos are released.
