9. Environment
 Java JDK5 or later version
 Android Studio/ Eclipse IDE

10.  OS
• Android application development on either of the following operating
systems:
 MicrosoftWindows.
 Mac OS X 10.5.8 or later version with Intel chip.
 Linux including GNU C Library 2.7 or later.
 Tools
• All the required tools to developAndroid applications are freely available
and can be downloaded from theWeb. Following is the list of software's
you will need before you start yourAndroid application programming.
1. Java JDK5 or later version
2. Android Studio /Android SDK and Eclipse IDE for Java Developers
(optional) andAndroid DevelopmentTools (ADT) Eclipse Plug-in
(optional)
Requirements for Android

11.  Download Android Studio
• From http://developer.android.com/sdk/installing/index.html
 System Requirements forWindows
• Microsoft®Windows® 8/7/Vista (32 or 64-bit)
• 2 GB RAM minimum, 4 GB RAM recommended
• 400 MB hard disk space
• At least 1 GB for Android SDK, emulator system images, and caches
• 1280 x 800 minimum screen resolution
• Java Development Kit (JDK) 7
• Optional for accelerated emulator: Intel® processor with support for
Intel®VT-x, Intel® EM64T (Intel® 64), and Execute Disable (XD) Bit
functionality
Requirements for Android

12. Create Project In Android

17. • The Android SDK includes a mobile device emulator — a virtual
mobile device that runs on your computer. The emulator lets you
develop and testAndroid applications without using a physical device.
 Limitations
• No support for placing or receiving actual phone calls.You can simulate
phone calls (placed and received) through the emulator console,
however.
• No support for USB connections
• No support for device-attached headphones
• No support for determining network connected state
• No support for determining SD card insert/eject
• No support for Bluetooth
Android Emulator

18. Core Libraries
 System C library, the standard C system library, tuned for embedded
Linux-based devices
 Media Libraries, support playback and recording of many popular audio
and video formats, as well as image files, including MPEG4, H.264, MP3,
AAC,AMR, JPG, and PNG
 Surface Manager, manages access to the display subsystem and seamlessly
composites 2D and 3D graphic layers from multiple applications
 WebKit, a modern web browser engine which powers both the Android
browser and an embeddable web view
 SGL, the underlying 2D graphics engine
 3D libraries, an implementation based on OpenGL ES 1.0 APIs
 FreeType , bitmap and vector font rendering
 SQLite , a powerful and lightweight relational database engine

19. Andoid Runtime
 The core of Android platform
 DalvikVirtual Machine
 Register-based
 Executes files in the Dalvik Executable (.dex) format
 Java core Libraries
 Provides most of the functionality of the Java programming
language.

20. Dalvik Virtual Machine
 Android custom implementation virtual machine
 Provides application portability and runtime consistency
 Runs optimized file format (.dex) and Dalvik bytecode
 Java .class / .jar files converted to .dex at build time
 Designed for embedded environment
 Supports multiple virtual machine processes per device
 Highly CPU-optimized bytecode interpreter
 Efficiently Using runtime memory
 Core Libraries
 Core APIs for Java language provide a powerful, yet simple and
familiar development platform

21. Application Framework
 Simplify the reuse of components
 Applications can publish their capabilities and any other
application may then make use of those capabilities
 Applications is a set of services and systems, include
 Views system, content providers, resources manager and so on

22.  Activity Manager, manages the lifecycle of applications
and provides a common navigation backstack
 Notification Manager, enables all applications to display
custom alerts in the status bar
 Resource Manager, providing access to non-code
resources such as localized strings, graphics, and layout files
 Content Providers, access data from other applications
(such as Contacts), or to share their own data
 Views, used to build an application, including lists, grids,
text boxes, buttons, and even an embeddable web browser

23. Android App software components
 Activity
 Service
 Broadcast Receiver
 Intent
 Content Provider

24. Android Layout
An Android layout is a class that handles arranging the way its children appear
on the screen. Anything that is a View (or inherits from View) can be a
child of a layout
 Anything that is aView (or inherits fromView) can be a child of a layout.
Android supports the following View Groups:
 Linear Layout
 Absolute Layout
 Table Layout
 Relative Layout
 Frame Layout
 ScrollView

25. Liner Layout
 Liner layout : all children aligned in single direction
horizontally or vertically
 The Linear Layout arranges views in a single column or
single row. Child views can either be arranged vertically
or horizontally.

26. Relative Layout
 The Relative Layout is very flexible layout
used in android for custom layout designing.
It gives us the flexibility to position our
component/view based on the relative or
sibling component’s position. Just because it
allows us to position the component
anywhere we want so it is considered as
most flexible layout.

27. Future Scope
 lot’s of large companies like, Flipkart,Amazon, Snapdeal, Paytm and others are doing businesses
with millions of transactions and they always need a large team to manage and adding additional
features in their apps.
 Digital India work in Smart phones application.
 Android apps development growth is, initially telecommunication companies likeAirtel,
Vodafone and Idea and others was depend on third part sites like Paytm, Free Recharge and
MobikWik after increase the demand of mobile recharge through these apps every company
release their own Android Apps.
 So build your future with Android App development is good choice, because it’s growing
industry and in nearby area it will capture all the industry .
 After good skills of Android app development you may also release your own app which attract
lots of users and make your businesses idea into action through android app development.
