E M
L
T the essential book if you want to learn how to natively target the iOS
TI
D and Android mobile platforms. You’ll wall through the process of building
TE the same application on both platforms, learning the diff erences and rela- u
A
L tive strengths and weaknesses of each. You’ll also get answers to the most
RE l
common questions developers have, and get you a leg up into understanding
t
the platforms so that you can get on and do the clever thing that only you’ve
i
thought of.
m
Each section starts by looking at installing the toolset and building a “Hello, World”
application to get comfortable. Then, you learn to build a proper, end-to-end appli-
o
cation that involves Internet communication over HTTP up to a public cloud-based
service, local storage using SQLite, a custom object-relational mapping layer and a b
device-specific user interface. The sections are preceded with a detailed section of
i
the cloud-based service implementation, as well as the application architecture and
l
functional specification. There’s also a bonus chapter on MonoTouch.
e
You’ll learn:

• D
How to develop, end-to-end, the same application on iPhone and
Android platforms.
e
•
The diff erent service architectures available on each platform,
v
concentrating on services related to storage, communications and
e
security.
• l
Key diff erences in deploying and managing applications on the
o
various platforms.
• How to translate experience at developing on one platform to speed p Multimobile
development when attempting a project on a diff erent platform.
