Android is basically a stack of software developed for using in mobile devices and has an Operating system, applications and middleware associated with it. One can easily find tools and the necessary APIs online to develop Android apps by using the programming language of Java.
The Framework of Android Apps
Android usually sends across a standard number of applications which includes calendar, contacts, email client, maps, SMS program and browser which are usually coded in Java. Android provides an easily accessible apps development platform in order to innovate on its existing applications. With this, the developers of the applications have full access to location information, device hardware, background services and other facilities. The best advantage of android apps is that they have reusable components wherein the applications are designed in a fashion to publish their own capabilities which can further by utilised by other applications. The services which are basis of all android apps are enumerated below:
1. An extensible, exhaustive option of VIEWS which includes grids, buttons, lists and web browser too. These can be easily used to build various applications.
2. Content Providers which facilitates the application in accessing and sharing data with other applications.
3. Resource manager which allows access to graphics, layout files and string type of non-coded resources.
4. Notification manager which enables displaying of alerts in your status bar.
5. Activity manager which helps manage working of applications by providing a navigation stack.
Running Of Android Apps
Android has a set of libraries which provide functional support available in libraries of Java. Android also includes C++ libraries which are used by applications. The capabilities of these libraries are revealed to developers by means of framework of applications. Some of these core libraries are System C library, Media Libraries, Surface Manager, LibWebCore, SGL3D libraries, Free Type and SQLite. Almost all android apps have their own process, with the instance of Dalvik machine which enable the device to run several VMs at one time efficiently.
Today Android apps are being used in a plethora of mobile phones which are available in the market, Ipods, Laptops, e-book readers and many more devices which are mobile. These applications have now made it possible to actually have the access of the world in one’s hands. Just a click and the world will be at your disposition. In this fast developing era, such applications are continually evolving and getting technologically upgrading every minute. The individuals across the globe have access to these applications which indeed has made the routine life not only easier but also extremely accessible. Android apps are a developing reality of the innovative technological advancements which residents of the planet earth are experiencing today in their day to day routine.
