INTRODUCTION

Android is a mobile phone operating system developed by
Google. Android is unique because Google is actively
developing the platform but giving it away for free to
hardware manufacturers and phone carriers who want to
use Android on their devices.

Contd..

• Based on Linux with a Java programming interface. It
provides tools, e.g. a compiler, debugger and a device
emulator as well as its own Java Virtual machine (Dalvik
Virtual Machine - DVM).

• It was initially developed by Android Inc., a firm later
purchased by Google, and lately by the Open Handset
Alliance.

• The unveiling of the Android distribution on 5 November
2007 was announced with the founding of the Open
Handset Alliance

Architecture


Android Architecture - Application

• Android provides a set of core applications:
– Email Client
– SMS Program
– Calendar
– Maps
– Browser
– Contacts
– Etc
• All applications are written using the Java language.


Android Architecture– App Framework

• Enabling and simplifying the reuse of components
– Developers have full access to the same framework APIs used
by the core applications.
– Users are allowed to replace components.


Android Architecture - Libraries

• Including a set of C/C++ libraries used by components of
the Android system
• Exposed to developers through the Android application
framework


Android Architecture - Runtime

• Core Libraries
– Providing most of the functionality available in the core libraries of
the Java language
– APIs
• Data Structures
• Utilities
• File Access
• Network Access
• Graphics
• Etc


Android Architecture – Runtime (Cont)

• Dalvik Virtual Machine
– Providing environment on which every Android application
runs
• Each Android application runs in its own process, with its own
instance of the Dalvik VM.
• Dalvik has been written such that a device can run multiple VMs
efficiently.
– Executing the Dalvik Executable (.dex) format
• .dex format is optimized for minimal memory footprint.
• Compilation


Android Architecture – Linux Kernel

 Relying on Linux Kernel 2.6 for core system services
• Memory and Process Management
• Network Stack
• Driver Model
• Security
 Providing an abstraction layer between the H/W and the rest of the
components

Contd..
• Android comes with an Android market which is an online
software store. It was developed by Google. It allows
Android users to select, and download applications
developed by third party developers and use them.
• Android applications are written in java programming
language. Android is available as open source for developers
to develop applications which can be further used for selling
in android market.
• Android relies on Linux version 2.6 for core system services
such as security, memory management, process
management, network stack, and driver model.
• For software development, Android provides Android
SDK (Software development kit).

– Need to modify Android’s settings to allow the installation of
applications from other sources. Under “Settings,” select
“Application Settings” and then enable “Unknown Sources.”
Also under “Settings,” select “SD Card” and “Phone Storage,”
and finally enable “Disable Use for USB Storage”
– This last step is easy. Open Command Prompt and type the
following: adb install applicationxxx.apk
– Application install successfully and shows under the device
application screen.


Application Un-installation from Device

• Uninstalling Android Applications
– Sometimes an application just needs to go. Whether a better
one has been found or an application has simply worn out its
welcome, it must be uninstalled. Uninstalling is as simple as it
was to install it.
– Open the Google Android Menu.
– Go to the Settings icon and select Applications.
– Next, click on Manage.
– A list of installed applications will appear.
– Select the one to be uninstalled and simply click Uninstall.
– With that, the application is uninstalled.


Create Android Emulator

• Click on the New button.

Contd..
• Provide all the details.

• Click on Create AVD button.

Contd..

• Select the newly created AVD and click on Start.


Contd..


Other Tools

• adb.exe –
– Android Debug Bridge is a versatile tool that lets you manage the state of
an emulator instance or Android-powered device. You can also use it to
install an Android application (.apk) file on a device.
– ADB allows you to interact with your phones file system through a terminal
based interface like command prompt. Since android is based on the Linux
platform, ADB can be used to perform advanced operations using a
command prompt window.


Contd..


• android.bat - This is an important development tool that
lets you:
• Create, delete, and view Android Virtual Devices (AVDs).
• Create and update Android projects.
• Update your Android SDK with new platforms, add-ons, and
documentation.


Contd..
• ddmss.bat
• Dalvik Debug Monitor Server (DDMS) is a debugging tool which provides port-
forwarding services, screen capture on the device, thread and heap information on
the device, logcat, process, and more.


Contd..
• Functionalities available using this utility


Contd..
• Capture the screen shot or copy the file from/to device.


Contd..

• emulator.exe
– The Android SDK includes a mobile device emulator — a
virtual mobile device that runs on your computer. The
emulator lets you develop and test Android applications
without using a physical device.
– When the emulator is running, you can interact with the
emulated mobile device just as you would an actual mobile
device, except that you use your mouse pointer to "touch" the
touch screen and can use some keyboard keys to invoke
certain keys on the device.

Ex - emulator -avd <avd_name> [-<option> ]


Development Environment

• ADT plugin for Eclipse
– Android Development Tools (ADT) is a plugin for the Eclipse IDE that
is designed to give you a powerful, integrated environment in which
to build Android applications.

– ADT extends the capabilities of Eclipse to let you quickly set up new
Android projects, create an application UI, add components based
on the Android Framework API, debug your applications using the
Android SDK tools, and even export signed (or unsigned) .apk files in
order to distribute your application.

– See the detail about configuration using the URL -
http://developer.android.com/sdk/eclipse-adt.html#installing


Device Root

• Root stands for administrator access which you can have
access to delete, modify, create new files inside the android
operating system, in short, gaining root access on your
android devices is like granting yourself an administrator
level which you can do all things you want unlike user level,
you don’t have the right to delete unworthy applications and
files that can consume a lot of space inside the internal
memory of the device.

• Getting root or rooting your phone is the process of
modifying the operating system on your device which will
grant you complete control over it.


Contd..
• This means you can overcome limitations that the carriers
and manufacturers put on your phone, extend system
functionality, and even upgrade it to a custom flavor of
Android.

• The name root equally known as Administrator on Windows
is called root.

• Getting rooted on the device will give you eternal freedom
to use the capabilities of your android device. But doing this
will might break your device and might void your warranty,
so if I you are afraid to have freedom on your device, I
recommend to do this once your device is out of warranty.
