Android Development Tutorials

Android is an absolute operating environment based upon the Linux V2.6 kernel. At first, the operation target for Android was the mobile-phone arena, as well as smart phones and lower-cost flip-phone devices. On the other hand, Android’s full range of computing services and rich functional support has the probable to pull out away from the mobile-phone market. Android can be helpful for other platforms and applications.

The Android platform is the creation of the Open Handset Alliance, a group of organizations collaborating to build a better mobile phone. The group, led by Google, includes mobile operators, device handset manufacturers, component manufacturers, software solution and platform providers, and marketing companies. From a software development standpoint, Android sits smack in the middle of the open source world.

This tutorial is projected for anyone attracted in beginning Android development on Eclipse using the Android development tools plug-in. It offers insight into the salient features of an Android app, along with a brief explanation of its basic components.

Android is an open-source software stack created for mobile phones and other devices. It is combines and builds upon parts of several dissimilar open source projects. The Android Open Source Project (AOSP) is tasked with the safeguarding and more expansion of Android. Many device manufacturers have brought to market devices running Android, and they are readably available around the world.

Android is the major Operating System for developing applications in today for various reasons. The main reasons being that it is Open Source and spontaneous. In addition it uses Java for development, which is somewhat an effortless language to get used to and develop in.

You cannot run standard Java bytecode on Android as it uses a special virtual machine. Android supports 2-D and 3-D graphics using the OpenGL libraries and supports data storage in a SQLite database.

The operating system controls the life cycle of your application. At any time the Android system may stop or destroy your application. The Android system defines a life cycle for activities via pre-defined methods.

By providing an open development platform, Android offers developers the facility to construct awfully rich and ground-breaking applications. Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much, much more.

Top 5 Android Development Tools

Android operating system has been designed primarily for touchscreen mobile devices such as smartphones and tablet computers.

Developed Initially by Android, Inc., backed financially by Google (later bought by Google in 2005), Android was unveiled in 2007 along with the founding of the Open Handset Alliance ( a consortium of hardware, software, and telecommunication companies devoted to advancing open standards for mobile devices).

Android is the buzz word in technology today with a market share of 42% across various devices worldwide. Android apps are open source unlike their competitors like iOS and Blackberry. The tools needed for their development are free and there is no need for purchase of a special developer phone or register your hardware as a development device.

Here are the Top5 Android Development tools currently trending in the market

  • Android SDK
  • Native Development Kit(NDK)
  • Titanium Mobile SDK
  • Hyper Next Android Creator
  • ADOBE AIR

1. Android SDK:

The Android Software Development Kit (SDK) provides you with the API libraries and developer tools necessary to build, test, and debug apps for Android. It is one of the most popular SDK used for Android.

Aspiring New Android developers can download the ADT Bundle to quickly start developing apps. It includes the essential Android SDK components and a version of the Eclipse IDE with built-in ADT (Android Developer Tools) to streamline your Android app development. These are some of the important components in ADT Bundle

  • Eclipse + ADT plugin
  • Android SDK Tools
  • Android Platform-tools
  • Current Version of the Android platform
  • Current Version of the Android system image for the emulatorMore

2. Native Development Kit(NDK):

The NDK is a toolset that allows android developers to implement parts of their app using native-code languages such as C and C++.NDK can be proved to be a lot of help for the developers as they can reuse existing code libraries written in these languages.

The most important point to be considered here is that NDK will not benefit most apps. Developer needs to balance its gains over draw-backs, as the native code may not always increase the performance, but generally increases the complexity. Prefer NDK only if it is essential to your app, never because you simply prefer to program in C/C++.

3. Titanium Mobile SDK:

The Titanium SDK provides community developers with an unmatched ability to create quality native, mobile web or rich hybrid applications to all platforms from a single code base, using JavaScript. With over 5,000 APIs, Titanium allows you to deliver an immersive user experience at a fraction of the time compared with traditional native platforms.

Although the Titanium suffers with some disadvantages like flexibility limitations, User Experience issues and complexity issues, Titanium still stands in the first place for Android and other cross platform apps development

4. Hyper Next Android Creator:

HyperNext Android Creator (HAC) is an easy to use software creation system that allows almost anyone to quickly start building their own Android apps that work. Apps developed on HAC enjoys good support on a wide range of devices.

HAC operation is based on HyperCard, which treats software as a stack of cards, where only one card is visible at a time and hence is quite well suited for mobile phone applications which allow single window operation.

The programming language used in HAC is “HyperNext” is much more similar to English, making it user friendly to learn and implement.

5. ADOBE AIR:

The Adobe® AIR® runtime enables developers to package the same code into native apps for iPhone, iPad, Kindle Fire, Nook Tablet, and other Android™ devices, reaching the mobile app stores for over 500 million devices.Running on Action Script,HTML,CSS AIR allows users mostly to develop cross platform mobile apps saving the time and minimising the development cost.

Along with these Tools there are some other tools like PhoneGap, BatteryTech SDK that should not be missed out.
