Android Training: Rich Functional Tool For Work and Play

Android training offers a wealth of opportunities for developers as well as app and website creators. Android refers to a total operating environment based on the Linux kernel V2.6. Through Android, a full range of computing services and intricate functional support can be accessed. This is why it has been deployed for mobile phones ranging from expensive smart phones to the low cost flip phone devices. So, what makes Android a game changer? Is it the vibrancy of this platform which can cater to the needs of everything from BlackBerry to iPhone and high volume mobile platform. Android training can equip you for the complete scale of the total mobile spectrum.

Delving into the Past: Android and the Open Handset Alliance

The Android platform resulted from the by product of the Open Handset Alliance, a set of organizations which partnered each other to come up with the ultimate mobile phone. Spearheaded by search engine major Google, this group included everyone from handset manufacturers to mobile operators, component manufacturer and software solutions providers and web platform as well as marketing firms. When it comes to open source software skill acquisition, Android training leads the fray.

Google and the Android Gold Rush

The leading first Android capable handset was the G1 and Android Developer Challenges were out forth by Google. The Android market was launched to ensure users could download apps directly to their phones. The new mobile platform has revolutionized the world of web and app development.

Android: More than A Desktop OS

Android has a complete range of capabilities which makes it much more than an OS. It is a layered environment and a tool based on the Linux kernel and has rich functions. Android User Interface System includes windows, views and widgets.  Another USP of Android is that it has a browser which is based on WebKit, open source browser engine which also fuels the Safari browser of the Apple iPhone.

Android offers a massive array of connectivity options including Wi-Fi, wireless data over cellular connections and Bluetooth. Two areas where mobile apps have always failed their desktop compatriots is data storage as well as graphics and media. Android meets the graphics test with in built support for 2D and 3D graphics.

Android: Application Architecture

Android runs on a Linux kernel and the apps are written in Java and run with a virtual machine. Every Android App runs within the Dalvik Virtual Machine, an open source technology.  Android apps comprise the following classifications:

• Activities
• Services
• Content Providers
• Broadcast Receivers

Activities– These are used to implement app with visible user interface. Activity commences when the user selects app from app launcher or home screen.

Services– When the app needs to exist for a long time, such as network monitoring or update checking app, services come into play.

Content Providers– These are database servers which manage access to consistent data such as SQLite database. If the app is simple, content providers are not required. If the app is complex however, content providers access data.

Broadcast Receiver– Android app will be launched for processing data element or responding to event such as text message receipt. The broadcast receiver provides the required configuration to install the app on the device. Declarative security reduces chances of rogue apps playing havoc with your mobile phone.

Android: Going Beyond Cell Phones, Advantages that Speak For Themselves

Android is a open source platform which is market moving and can progress beyond mobile phones. In the mobile world however, Android is the most popular OS. If you are a multi-tasker,the Android tool is the right addition to your kit. Android OS is a trending OS used in phones.

More versions were released from 2009 to 2010, 2011, 2012, 2013, 2014, 2015 and 2015. Android is a mobile OS associated with the Linux kernel developed by Google. This mobile app OS is designed for touch screen devices such as smartphones, tablets, specialized UI and android enabled vehicles and wearables.

Android OS uses touch inputs for manipulation of on screen objects. Android basically equals a virtual keyboard and was designed for touchscreen inputs. This is the reason why Android has moved beyond mobile phones to encompass in game equipments, personal computers, cameras and other electronic devices. Not only is Android OS the most widely used system, and the highest selling mobile app system. This Linux based OS is used for smartphones and tablets and allows end users to develop and install their own apps within the Android framework. Android OS is based on Linux. The Libraries layer for Android holds all the native libraries written in C or C++and has capabilities akin to the application layer.

Key native libraries include Surface Manager, Media Framework, System C Libraries, Open Gl ES Libraries  and SQLite. Android Runtime comprises the Dalvik Virtual Machine which is for embedded systems. It consists of core libraries such as Java libraries. It is present for all devices. Android OS is derived from the Linux Kernel 2.6 and put together for the electronic equipments. Kernel is the Hardware Abstraction Layer located between hardware and Android software.

Android: World’s Most Popular Open Source Code

Android is an open source code freely available for all developers, known as Android SDK, it can be downloaded and worked on Android app in numerous ways. If third party apps have to be developed, the open source code is the key.  Android SDK carries a memory requirement of 8.5 GB and one needs to access free disk space of 30 gigabytes. Prior to installing the SDK and starting cross compilation, there are various prerequisites which must be met.
