Core of Android

• Android is a Linux kernel based Operating system

• Android implements the Linux kernel and contributes to kernel development as well

• Other modules of Android are written on top of the Linux kernel

• Android inherits the security of Linux through kernel

Android – Programming Language

• Android is based on Apache Harmony, a clean room implementation of the Java class libraries & an independently developed virtual machine called ”Dalvik”

• Applications are developed for Android OS using a specialized version of Java (Dalvik)

• The classes used in Android are different from that of Java classes

• Java Byte code files are compiled using Dex Compilers to generate Dalvik Byte code files, which will be used to create Dalvik executables

Android – Programming Language

Oracle Vs Google Lawsuit

• Oracle America (formerly Sun) had sued Google for infringing its copyrights in Java language

• Google claimed that Android is based on Apache Harmony, a clean room implementation of the Java class libraries & an independently developed virtual machine called ”Dalvik”

• In May 2012, the jury in this case found that Google did not infringe on Oracle's patents, and the trial judge ruled that the structure of the Java APIs used by Google was not copyrightable

Android – Versions

• Android Beta• Android 1.0 - Astro• Android 1.1 - Bender• Android 1.5 - Cupcake• Android 1.6 - Donut• Android 2.0 / 2.1 - Éclair• Android 2.2 - Froyo (Frozen Yogurt)• Android 2.3 - Gingerbread• Android 3.0 - Honeycomb (targeted for tablets)• Android 4.0 - Ice cream Sandwich• Android 4.1/4.2/4.3 - Jellybean• Android 5.0 - KitKat (announced)

Android Architecture

Android Architecture – Linux Kernel

The Linux kernel used in Android core has the following components:

• Display Driver – Driver for interfacing with hardware display

• Camera Driver – Driver to send commands to Camera

• Flash Memory Driver – Driver to interact with USB flash memory devices

• Wi-Fi Driver – Driver used for interfacing Wi-Fi capability

• Audio Driver – Driver to interact with Audio devices (speaker, microphone)

Android Architecture – Libraries

Android libraries has the following constituents:

• Surface Manager – Used for compositing window manager with off-screen buffering

• SQLite – database engine used in android for data storage purposes

• WebKit – browser engine used to display HTML content

• OpenGL|ES – Used to render 2D/3D graphics contents on the screen

• SGL – Skia Graphics Library

Architecture – Runtime Libraries

Android runtime contains the following modules:

• Core Libraries – Core Android Libraries are different from JavaSE & JavaME libraries. However these libraries provide most of the functionalities defined in the Java SE libraries.

• Dalvik Virtual Machine(DVM) – Optimized for low processing power and low memory environments. It runs .dex files, which provides higher efficiency in low resource environments. The Dalvik VM allows multiple instance of VM to be created simultaneously providing security, isolation, memory management and threading support.

Architecture – Appln Framework

Application framework consists of following modules :

• Activity Manager: Manages the activity life cycle of applications

• Content Providers: Manage the data sharing between applications

• Telephony Manager: Manages all voice calls

• Location Manager: Location management, using GPS / A-GPS

• Resource Manager: Manage the different types of resources we use in our applications

Android Architecture - Applications

Applications are the top most layer in the Android architecture, which interacts with the end user. Several standard applications comes pre-installed with every device, such as:

• SMS client app

• Phone Dialer

• Web browser

• Contact manager

• Google Play (Marketplace for Android apps)

• Alarm Clock

ADT - Android Development Tools

Applications can be developed for Android OS using the following tools:

• Android SDK (Eclipse + ADT Plugin)• Native Dev Kit• App Inventor for Android• Basic4Android• Hyper Next Android Creator(HAC)• Simple Direct Media Layer (SDL)• RFO Basic

ADT – Native Development Kit(NDK)

• Libraries written in C/C++ can be compiled to x86 native code and installed using the Android Native Development Kit (NDK)

NDK is based on command-line tools and requires invoking them manually to build, deploy and debug the apps.oracle training in chennai

• Native classes can be called from Java code running under the Dalvik VM using the System.loadLibrary() call, which is part of the standard Android Java classes

• Several third-party tools allow integration of NDK with Eclipse and Visual Studio

Web/GUI based ADTs

App Inventor for Android

• A web based visual development environment for novice programmers• It is based on MIT's Open Blocks Java library• This is a drag and drop model GUI application developer for Android• This development kit can be accessed online at http://appinventor.mit.edu/

Basic4Android

• Inspired by Visual Basic and Visual Studio• Commercial Android Development Product• Strong community of developers
