The distinguishing quality of open source software is that it does not impose any kind of restriction on the free development process of anyone. This means that anyone can freely contribute in the source code of open source software and this, in a long run, guarantees the widespread acceptance of the software itself.

Same is the case with Google’s operating system Android. Google officially provides Android tutorials for freelance developers so that they might have proper guidance during the process of development. Besides Google, various third-party software developers also provide these tutorials online which can be followed free of any cost.

Google provides its development kits and various tools and plugins which considerably benefit the developer during the process of app development. The plugins efficiently handle the project creation and management and make sure that the development process is greatly enhanced. These Android tutorials generally go through the process of installation and development in details and provide guidance about the graphical user interface used in Android.

Some of the important points that are usually stressed upon during the course of these tutorials are the initial setup that is required for software development, building initial and easy to develop applications, the short-term and long-term structuring of the projects, using toast messaging and long click dialog boxes, understanding and playing with the layout, localizing the content and storing the data, dealing with security problems and permissions, understanding and building graphics, integrating maps, understanding and developing 2D and 3D stuff, testing and debugging and giving final touch to the developed applications. So these tutorials provide guidance form the very basic levels to highly advanced levels.

There are various platforms for Android development and the content of guidance provided in Android tutorials would also vary according to these platforms. For example, the methods used for a certain platform might not apply on another platform. So what needs to be decided before hand is that which platform a developer would be using during the development process.

At initial levels, most of the developers prefer Eclipse which is quite a famous platform for Android development and is also being used on various Android forums. Official tutorials from Google are also being provided in Eclipse. Although tutorials on other platforms are also available over the internet, but the most commonly available tutorials usually prefer Eclipse.

Among the official tutorials on Android that are being provided by Google, Android Bootcamp Training Course is quite noteworthy. This program specifically trains the developers for the designing and building process of mobile applications using Android. Main stress is laid upon the various building blocks for application development and the interaction of those building blocks with each other. The course has been designed for the software developers who are interested in designing, creating and testing process of applications for Android based mobile devices.

The completion of this course pretty much guarantees a sound ability to build Android apps for mobile devices. The number of people participating in these courses and tutorials is constantly increasing with the increasing popularity of Android. And pretty much showcases the immense success of the open source software trend whose foundations were laid many years ago.
