We provide two courses in Android App Development courses, Android Training Pro. And Android Training Expert. Android offers a unified approach to application development for mobile devices which means developers need only develop for Android, and their applications should be able to run on different devices powered by Android. CNC WEB WORLD provides live project training. So it is very beneficial to you for development of any software.

1. *Introduction to
Android App
Development

2. *
*Android is a software based stand and operating system
for mobile devices.
*It is placed on Linux Kernel.
*It is developed by Google and later the Open Handset
Alliance(OHA).
*Java language is mainly used to write the code.

3. *
*Google acquired the startup company Android Inc. in
2005 to start the development of the Android Platform.
In late 2007, a group of industry leaders came together
around the Android Platform to form the Open Handset
Alliance.
*The Android SDK was first issued as an “early look”
release in November 2007.
*In September 2008 T-Mobile announced the availability
of the T-Mobile G1, the first smartphone based on the
Android Platform.
*A few days after that, Google announced the
availability of Android SDK Release Candidate 1.0.
*In October 2008, Google made the source code of the
Android Platform available under Apache’s open source
license.

*The open handset alliance is a business
alliance of company to develop open
standard for mobile devices.

8. * The software stack is divided in to 4 layers:
1) The Application Layer
2) The application framework
3) The libraries and run time
4) The kernel

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

10. Enabling and simplifying the rework of components
 Developers have full purses to the same
framework APIs used by the core applications.
 Users are granted to substitute components.
• View System: It is used to form an application
including grids, text boxes, grids, buttons, lists
and planted web browser.
• Content Providers: Enabling applications to
access data from other applications or to share
their own data.
• Resource manager: Providing access to non-code
resources (localized strings, graphics and layout
files).

11. *Notification Manager: Enabling all applications to
display customer alerts in the status bar.
*Activity Manager: Managing the lifecycle of
applications and providing a common navigation
backstack.
*Package manager: It is use to retrieve the data about
installed packages on device.
*Window manager: It is use to views and layouts.
*Technology manager: It is use to handle settings of
network connection and all information about services
on device.
*Location manager: It fires alerts when user enters or
leaves a specified geographical location.

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

13. 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

14. 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.
Register-based virtual machine

15. Dalvik Virtual Machine (Cont)
Executing the Dalvik Executable (.dex) format
.dex format is optimized for minimal
memory footprint.
Compilation
Relying on the Linux Kernel for:
Threading
Low-level memory management

16. Relying on Linux Kernel 2.6 for core system servi
ces
 Memory and Process Management
 Network Stack
 Driver Model
 Security
Providing an abstraction layer between the H/W
and the rest of the S/W stack
