What is Android?

Android is the world’s most popular mobile platform. Android is itself Linux-based Operating System specially designed for Smartphones and Tablet computers. Android is being developed by Google and Open Handset Alliance. Important thing is that, Android is an open source project released under Apache License. Unveiled in 2007 Android is being maintained and developed  further  by Android Open Source Project(AOSP) supported by Google. Android provides a huge scope for development of innovative apps and already has a large community of developers writing applications that extend the functionality of devices, written primarily in Java language with Android API and SDK provided by Google.

Market Trend
Google supplies its mobile platform, Android, to a large number of mobile manufacturers. Notable amongst them are Samsung and HTC apart from numerous other smaller manufacturers.  With Samsung becoming the largest seller of Smartphones across the globe, so has Android become the largest platform being used across the globe.

Android‘s overall smartphone market share has jumped to 72.4% in Q3 2012, up from 52.5% in the same period last year

So What & How can I develop Android Applications?

As a smartphone operating system android open source project provides you everything you require to develop applications based on android mobile devices. In short its a small computing device in your hand and you can use it  anywhere you can. There can be numerous applications  like below –

  • Controlling a Robot right from your Android Phone by using its touchscreen and sensors

What should you know to develop Android Applications?
New learners often face a problem that what options(language, tools) are available to start developing applications for android phone. The main objective of this article and future series are to provide you information about all available possibilities to get started with android application development so that you can decide which option is better and more easy to start developing your own application for android.
The options available are -:
  1. Java (For developers familiar with Java)Android Application can be developed using Java language and Apps runs on Android Platform with the help of a virtual machine (Dalvik VM) similar to that of JVM
  2. flex (Android applications in Flash)
  3. C or C++ (native applications – applications that run directly on hardware- requires Android NDK to build applications)
Android System Programming
Android System Level Programming is more about changing in Kernel Sources, Building customize device driver, compiling, loading and booting Android kernel on ARM based  embedded development board and related stuffs. To program at system level you should have fine knowledge in Linux, C/C++, Java, JNI and Embedded things.
For your Applications – Depending on the kind of application you should decide to use Java or C/C++.I’d use C/C++ for anything that requires above average computational power and games — Java for the rest.
