Best Android Training In Chennai Adyar With Placement

What is Android?

Android Training is the name of the mobile operating system made by American company; Google. It most commonly comes installed on a variety of smartphones and tablets from a host of manufacturers offering users access to Google’s own services like Search, YouTube, Maps, Gmail and more.

This means you can easily look for information on the web, watch videos, search for directions and write emails on your phone, just as you would on your computer, but there’s more to Android than these simple examples.

What can an Android phone do?

Android phones are highly customisable and as such can be altered to suit your tastes and needs; with wallpapers, themes and launchers which completely change the look of your device’s interface. You can download applications to do all sorts of things like check your Facebook and Twitter feeds, manage your bank account, order pizza and play games. You can plan events on from your phone’s calendar and see them on your computer or browse websites on your desktop and pick them up on your phone.

Another neat feature of Android is that it automatically backs up your contacts for you. When you set up an Android phone you’ll need to create a Google Account or sign in with an existing one. Every time you save a number to the address book of your Android phone it will be synced to your Google Account.

The benefit of this is that if you lose your phone all of your numbers will be saved. The next time you get an Android phone (or an iPhone or Windows Phone if you prefer) and sign in with your Google Account, all of your contacts and friend’s numbers will be displayed in your new phone’s address book immediately, no need to transfer or back them up anywhere else.

Syncing is a way for your phone to keep all your information; websites, contacts, calendar entries and apps up-to-date. This can happen over your phone’s mobile data or WiFi connection, seamlessly, in the background.

What is API Level?

API Level is an integer value that indicates the Android framework API release versions for Android platform. Each revision made is assigned with a new incremental API Level value.

The framework API that an Android platform delivers is specified using an integer identifier called “API Level”. Each Android platform version supports exactly one API Level. The initial release of the Android platform provided API Level 1 and subsequent releases have incremented the API Level.

The API Level identifier lets the Android platform describe the minimum and maximum framework API revision that it supports

The framework API’s are used to build Android application to interact with Android system. The framework API consists of following components

  1. A core set of packages and classes
  2. A set of XML elements and attributes for declaring a manifest file
  3. A set of XML elements and attributes for declaring and accessing resources
  4. A set of Intents
  5. A set of permissions that applications can request, as well as permission enforcements included in the system
  6. Each successive version of the Android platform can include updates to the Android application framework API that it delivers.

Android Features

Android studio is based on IntelliJ IDEA, which does all the functionality that Eclipse with ADT plug-in do, with lot more additional features. The initial version of android studio offers

  1. Gradle-based build support.
  2. Android-specific refactoring and quick fixes
  3. Lint tools to catch performance, usability, version compatibility and other problems
  4. ProGuard and app-signing capabilities
  5. Template-based wizards to create common Android designs and components.
  6. A rich layout editor: it allows you to drag-and-drop UI components, preview layouts on multiple screen configurations. Preview appears instantly as you change in the layout editor. You can choose a language, and can see the preview of layout with that locale.
  7. Rich Color Preview editor: While adding colors as a resource, and we can see the color preview at the left hand side of the editor.
  8. Deep Code Analysis: If you point to a line and it gives detailed explanation about an exception based on the annotation added. And you can also know which constants are allowed for which API. It also has the powerful code completion. You can also inspect code in whole project, InteliJ lists all Lint errors during code inspection.

Note: Android Studio is currently available as an early access preview. Several features are either incomplete or not yet implemented and you may encounter bugs. If you are not comfortable using an unfinished product, you may want to instead download (or continue to use) the ADT Bundle (Eclipse with the ADT Plug-in)

With this new features, hope it will help developers to get their development faster.
