3. Introduction
What is Android?
• A software platform and operating system for mobile devices
• Android is a software stack for mobile devices that includes an
operating system, middleware and key applications. The Android SDK
provides the tools and APIs necessary to begin developing applications
on the Android platform using the Java programming language.
• Based on the Linux kernel
• Developed by Google and later the Open Handset Alliance (OHA)
• Allows writing managed code in the Java language
• Possibility to write applications in other languages and compiling it to
ARM native code (support of Google? No)
• Unveiling of the Android platform was announced on 5 November 2007
with the founding of OHA

5. Platform
2.1 Hardware
Android is not a single piece of hardware; it's a complete, end-to-end software
platform that can be adapted to work on any number of hardware configurations.
Everything is there, from the bootloader all the way up to the applications.

6. Platform
2.2 Operating System(s)
• Android uses Linux for its device drivers, memory management, process
management, and networking.

7. Platform
2.3 Network Connectivity
It supports wireless communications using:
 GSM mobile-phone technology
 3G
 Edge
 802.11 Wi-Fi networks

2.4 Security
Android is a multi-process system, in which each application (and parts of the
system) runs in its own process. Most security between applications and the
system is enforced at the process level through standard Linux facilities, such as
user and group IDs that are assigned to applications.
Additional finer-grained security features are provided through a "permission"
mechanism that enforces restrictions on the specific operations that a particular
process can perform, and per-URI permissions for granting ad-hoc access to
specific pieces of data.

2.6 Future possibilities
• Google Android Sales to Overtake iPhone in 2012
• The OHA is committed to make their vision a reality: to deploy the Android
platform for every mobile operator, handset manufacturers and developers to
build innovative devices
• Intel doesn’t want to lose ownership of the netbook market, so they need to
prepare for anything, including Android
• Fujitsu launched an initiative to offer consulting and engineering expertise to
help run Android on embedded hardware, which aside from cellphones, mobile
internet devices, and portable media players, could include GPS devices, thin-
client computers and set-top boxes.
• More Android devices are coming and some will push the envelope even
further

11. Overall evaluation
4.1 Advantages
There are a host of advantages that Google’s Android will derive from being an
open source software. Some of the advantages include:
• The ability for anyone to customize the Google Android platform
• The consumer will benefit from having a wide range of mobile applications to
choose from since the monopoly will be broken by Google Android
• Men will be able to customize a mobile phones using Google Android platform
like never before
• Features like weather details, opening screen, live RSS feeds and even the
icons on the opening screen will be able to be customized
• As a result of many mobile phones carrying Google Android, companies will
come up with such innovative products like the location
• In addition the entertainment functionalities will be taken a notch higher by
Google Android being able to offer online real time multiplayer games

12. C and C++
• C++ is a general-purpose programming language with
a bias towards systems programming that
– is a better C
– supports data abstraction
– supports object-oriented programming
– supports generic programming
C:
 Functions and structs
 Machine model (basic types and operations)
 Compilation and linkage model

13. Missing in C (from a C++ perspective)
• Classes and member functions
– Use struct and global functions
• Derived classes and virtual functions
– Use struct , global functions, and pointers to functions
– You can do OOP in C, but not cleanly, and why would you want to?
– You can do GP in C, but why would you want to?
• Templates and inline functions
– Use macros
• Exceptions
– Use error-codes, error-return values, etc.
• Function overloading
– Give each function a separate name
• new/delete
– Use malloc()/free()
• References
– Use pointers
• const in constant expressions
– Use macros

15. Have a C programming reference always
with you. Study or check on the go!.
Complete C language programming
reference from cheat sheets and quick
reference cards, to primer language
programming tutorials, complete
reference, code style industry
recommendations, advanced pointer
tutorials and more.
Use the possibilities the mobile brings
you, allowing to study or check anything
you want on the go. Don't waste time on
transportation, use your mobile and
study and check anything you want

17. Learn C++ Programming right over your Android phone or tablet with this great
app. Popular videos by Programmers Institute help you to learn C++
programming even if you have never programmed before. You get the basics
form the ground level to get you started and on your way in a step by step
fashion.
Set you phone or tablet by your computer and let this app help you through the
beginning steps. More apps like this are on the way!

20. Requirements: Android 2.1+
Overview: C4droid is a C
compiler for Android.
Root is not required, but if
you have rooted your device
or have enough internal
memory, you can get C++
support,

21. Long click save button to "save
as", long click run to run with
arguments.
C4droid already has almost full C
language support, so you don't
need to wait when it will be added.
You can to write your
own applications on the Android
phone, and run them. This app uses
TCC and uClibc, so it has full
support of ANSI C and some
support of ISO C99. C4droid can
be used for educational purposes
or to practice in C language.

22. Result of compilation (binary) is placed
in
"/data/data/com.n0n3m4.droidc/files/te
mp", because sdcard doesn't have
permission for execution by default.

23. Some components of C4droid
are LGPL-licensed. You
can download used source
code of TCC and uClibc on
their websites. C4droid
includes Android Terminal
Emulator so you can to run
your application comfortably.

25. Android Market Description Simple
C/C++ compiler / interpreter for
educational purpose.
some part of C language is implemented,
C++ language support will be done in
some future.
*. No Internet Connection is required to
run the code.
Uses internet connection Once when you
run the app
only for licensing purpose.

26. *. You don't need to root the phone to
run the app.
Works well on non-rooted devices.

28. The Android NDK is a companion tool
to the Android SDK that lets you build
performance-critical portions of your
apps in native code. It provides headers
and libraries that allow you to build
activities, handle user input, use
hardware sensors, access application
resources, and more, when
programming in C or C++. If you write
native code, your applications are still
packaged into an .apk file and they still
run inside of a virtual machine on the
device. The fundamental Android
application model does not change.

29. The NDK provides:
* A set of tools and build files used to
generate native code libraries from C
and C++ sources
* A way to embed the corresponding
native libraries into an application
package file (.apk) that can be deployed
on Android devices
* A set of native system headers and
libraries that will be supported in all
future versions of the Android platform,
starting from Android 1.5
* Documentation, samples, and
tutorials
