INTRODUCTION

The Open Handset Alliance (OHA) is a

consortium/association of 84 firms to develop open

standards for mobile devices.

Member firms include the following:

Android is an operating system

designed primarily for touchscreen

mobile devices such as smartphones and tablet computers,

developed by Google in conjunction with the Open Handset

Alliance.

Founded by open handset alliance (OHA) by a group in 2003 by ANDY ROBIN,RICH MINER (co founder of wildfire communication) NICK SEARS (vpt-moblie) CHRIS WHITE(design and interface developed at web TV).

ANDROID logo designed by California based graphic designer IRINA BLOCK.

Google backed financially and latter brought in android in 2005.

GOOGLE reveled in 2007 with first mobile android powered phone which was HTC DREAM was sold in October 22nd 2008.

ANDROID is a open source and Google releases the code under Apache license.

October 2012 approximately 700000 apps were available for downloads.

HISTORY:

ArchitectureOf

ANDROID

First layer in system architecture These include the applications shipped with

android like the email client, SMS client, maps, browsers and also the applications developed and distributed through the Android market.

Applications

Second layer in system architecture These include the programs that manage

the basic functions of the phone like resource allocation, voice call management, etc

Application Framework

The layer above to the Linux kernel is the Android’s native libraries.

These libraries are written in C/C++ languages.

These libraries also run as processes within the underlying Linux kernel. 

The libraries are nothing but a set of instructions that tell the device how to handle different kinds of data (e.g. The media libraries support playing or recording various audio/video formats)

Libraries

SQLite:This is a lightweight yet powerful relational database engine available for all applications to store data.

Webkit:This is a browser engine providing tools for browsing web pages.

Surface Manager: This is responsible for the graphics on the device screens

OpenGL: Used to render 2D or 3D graphics to the screen

Some of the key libraries are listed below:

This is located on the same layer as the libraries layer.

 It consists of the core JAVA libraries and the Dalvik virtual machine.

The core Java libraries are used for developing Android based applications.

Dalvik VMs help in achieving the following: - better memory management -an application cannot interfere with other applications without permissions - threading support

Android Runtime

The diagram below is a pictorial representation of the Android environment.

It can be observed that each Android application runs under a separate virtual instance and each application has a unique user-id assigned to it.

This is last layer in system architecture Device drivers, power management,

process management and networking services depend on the layer

Android using Linux kernel 2.6 and android developed over time have been harmonized.

Android is not exactly Linux.

Linux Kernel

The applications in Android can be mainly classified into two categories:

-Android browser-based applications

-Android-based applications (Android application package files – .apk extension files)

Penetration testing of Android apps

We want to analyze files within the device,so how do we do this ?

ADB (windows,linux,mac)

Android Filesystem Access

Android Debug Bridge (adb) command -Access a shell -Pull/push files -Many more

wHY ANDROID 4.4 IS BETTER THAN OTHER OPERATING SYSTEMS?With Android operating system (OS) KitKat version 4.4 rolling out to mobile devices across the

globe, Google is on to something—Android is now more popular than iOS or the Windows phone. The OS tends to garner rave reviews for its ease of use and open source, but many iOS or Windows phone users argue that their preferred operating system can do just as much. In some respects that’s true, but here are 10 features unique to Android’s OS.1) Near Field Communication (NFC)Most Android devices support NFC, which allows electronic devices to easily interact across short distances. The main aim here is to create a payment option that is simpler than carrying credit cards or cash, and while the market hasn’t exploded as many experts had predicted, there may be an alternative in the works, in the form of Bluetooth Low Energy (BLE).2) Alternate KeyboardsAndroid supports multiple keyboards and makes them easy to install; the SwiftKey, Skype, and 8pen apps all offer ways to quickly change up your keyboard style. Other mobile operating systems either don’t permit extra keyboards at all, or the process to install and use them are tedious and time-consuming.3) Infrared TransmissionThe Android operating system supports a built-in infrared transmitter, allowing you to use your phone or tablet as a remote control.4) No-Touch ControlUsing Android apps such as Wave Control, users can control their phones touch-free, using only gestures. Have messy hands but need to turn off your screen or change a song? Simple. This could prove especially useful if you’re driving, so you can keep both eyes on the road.

5) AutomationThe Tasker app lets you not only control app permissions but also automate them. Do you only want your location services to be active during the day? Want to create a customized way to start your music—for example, with a voice command and at a certain volume? Tasker can help.6) Wireless App DownloadsAccessing app stores on any mobile device can be frustrating, but iOS makes it a little more difficult—download an app on your computer, and it won’t sync to your mobile device until you plug in and access iTunes. Using the Android Market or third-party options like AppBrain, meanwhile, let you download apps on your PC and then automatically sync them your Droid, no plugging required.7) Storage and Battery SwapAndroid phones also have unique hardware capabilities. Google’s OS makes it possible to remove and upgrade your battery or to replace one that no longer holds a charge. In addition, Android phones come with SD card slots for expandable storage.8) Custom Home ScreensWhile it’s possible to hack certain phones to customize the home screen, Android comes with this capability from the get-go. Download a third-party launcher like Nova, Apex or Slide and you can add gestures, new shortcuts, or even performance enhancements for older-model devices.9) WidgetsApps are versatile, but sometimes you want information at a glance instead of having to open an app and wait for it to load. Android widgets let you display just about any feature you choose, right on the home screen—including weather apps, music widgets, or productivity tools that helpfully remind you of upcoming meetings or approaching deadlines.10) Custom ROMsThis is a big one. Because the Android operating system is open source, developers can tweak the current OS and build their own versions, which users can download and install in place of the stock OS. Some are filled with features, while others change the look and feel of a device. Chances are if there’s a feature you want, someone has already built a custom ROM for it.
