 Can be likened to a web page.

 Each page is a fragment
 We need an adapter to manage the Fragments
Okason.com

37. XML Layout Fundamentals
 Elements on the screen are laid out with XML
 XML defines “how it looks”
 Java code defines “how it works”
 Each screen has a root layout
 Everything in screen derives from the View
object
 Programmatic reference need to use XMLOkason.com

38. Java Basics for Android
 This course is not heavy on “core” Java
Programming
 The course is Android Development Focused
 A lot of the code/concepts are unique to Android
and
 Android provides lots of plumbing code
 When in Doubt Copy and Paste
 Some knowledge of Object Oriented
Programming highly recommended
Okason.com

39. Object Oriented Programming (OOP)
 Objects are key to
understanding OOP.
 They have
state and behavior.
 They stores state
in fields/variables
 They exposes behavior
through methods or functions
 Are created from Classes Okason.com

40. External Libraries
 Are programs that you did not write
 Use other people work often for free
 Why do you want to use other people
Okason.com

41. Programmers Are
Integrators

42. Don’t Repeat Yourself
 Find out the
piece of the
puzzle that
already exist
 Create the parts
that are needed
 Put them
together Okason.com

43. Lesson Learned
Develop
You need just enough Java to get started,
Android programming consists mainly of
responding to lifecycle events. Use
FindViewById to link view objects to Java
variables.
Deploy
Damn it! 84 other developers just
published their app while you are busy
building yours. They should have waited
for you but they did not. So you have to
create amazing graphic assets, compelling
app description to compete.
Design
XML is used to layout out widgets on the
screen. Every widget derives from View.
Composite views can contain other views
such as Linear Layout, Relative Layout,
etc
Debug
Something will always go wrong, someone
planted a bug in your beautiful code – so
go crush that bug. The debugger got you
covered you just have to get used to
reading stack trace!.
Did your light bulb go off?
Did you get an app
mindset? Did this course
scare you off?
