Description/Agenda
< This hands-on course conveys the fundamental skills necessary to deploy
Android Apps on mobile devices such as phones and tablets. Attendees will
design and build a variety of Android Apps throughout the course. Previous
Java programming knowledge is not essential, but basic programming
experience is required. Java code used in the exercises is fully explained.
The course emphasizes proper layout of the user interface (UI), including
how to add buttons, labels, textboxes, checkboxes, images and other widgets
to the UI. Students will learn how to utilize Android's XML-based layout
system, which builds the UI with containers and widgets, as well as how to
set wallpapers and add menus to the UI. Students practice with dialog
techniques including the display of popup messages.
Students also learn how to handle screen rotation, and how to define UIs
so they can adjust for different screen sizes. The course teaches students
how to accept user input from keyboards (either externally attached or from
the built-in keyboard), how to use the date/time picker, and how to present
users with choices using Selection Lists. Students will learn how to add
tabs to the UI, as well as how to display HTML content using the built-in
WebKit browser.
Students will learn how to program control of state changes in the
Activity Lifecycle: active, paused, stopped or dead. For instance, since
Apps often run on phones, taking a call may send an App from the active
state to the paused state. Or, if battery life is low the App may be forced
into the dead state. Student will learn how to manage Activities moving
between these states so that Apps can, for example, save inputted data
before transitioning into the dead or paused state. Also related to this is
the ability for an Activity to launch Sub-Activities, which allows Apps to
run processes in the background (such as downloading files).
Coverage of data storage includes best practices for storing images and
files. Student will also learn how to embed SQLite databases in Apps, and
then use these databases to store and retrieve any kind of data.
The course emphasizes Service Oriented Architecture (SOA), and students
learn how to connect Apps to web services such as Google Maps and UPS's
package tracking API. In addition to using outside web services, the course
also demonstrates how to use many of a phone or tablet's built-in features
such as the camera, location service (which determines where the device is
physically located), and the Accelerometer (which determines if the device
is being tilted and how fast it's being tilted). Additional topics include
how to play audio and video, and standard techniques for storage and
retrieval.
Students employ the Eclipse editor and the Android Developer Tools (ADT)
plugin to perform comprehensive hands on exercises throughout the course to
reinforce learning and develop real competency. Various alternative App
development environments are compared to Eclipse, including Flex, Air and
PhoneGap. The course provides students with an introduction to a variety of
Android App development resources.
Course Prerequisites: Prior experience with a scripting or
programming language is required. Java skills are helpful but not required.
