Mobile Technology
Mobile technology is the technology used for cellular communication. Mobile code division multiple access
(CDMA) technology has evolved rapidly over the past few years. Since the start of this millennium, a standard
mobile device has gone from being no more than a simple two-way pager to being a mobile phone, GPS navigation
device, an embedded web browser and instant messaging client, and a handheld game console. Many experts argue
that the future of computer technology rests in mobile computing with wireless networking. Mobile computing by
way of tablet computers is becoming more popular. The most popular tablet at the moment is the iPad, by Apple.
Tablets are available on the 3G and 4G networks.

Android OS
Android is a Linux-based operating system. Google releases the Android code as open source, under the Apache
License. The Android Open Source Project (AOSP), led by Google, is tasked with the maintenance and further
development of Android.
Android consists of a kernel based on the Linux kernel 2.6 and Linux Kernel 3.x (Android 4.0 onwards), with
middleware, libraries and APIs written in C and application software running on an application framework which
includes Java-compatible libraries based on Apache Harmony. Android uses the Dalvik virtual machine with just-
in-time compilation to run Dalvik dex-code (Dalvik Executable), which is usually translated from Java byte code.
The main hardware platform for Android is the ARM architecture.

Symbian OS
Symbian switched to using standard C++ with Qt as the main SDK, which can be used with either Qt Creator or
Carbide.c++. Qt supports the older Symbian/S60 3rd (starting with Feature Pack 1, aka S60 3.1) and
Symbian/S60 5th Edition (aka S60 5.0) releases, as well as the new Symbian platform. It also supports Maemo and
MeeGo, Windows, Linux and Mac OS X.
Alternative application development can be done using Python (see Python for S60), Adobe Flash Lite or Java ME.
Symbian OS previously used a Symbian specific C++ version, along with Carbide.c++ integrated development
environment (IDE), as the native application development environment.
The SDK for Symbian is standard C++, using Qt. It can be used with either Qt Creator, or Carbide (the older IDE
previously used for Symbian development).
Symbian devices can also be programmed using Python, Java ME, Flash Lite, Ruby, .NET, Web Runtime (WRT)
Widgets and Standard C/C++. Visual Basic programmers can use NS Basic to develop apps for S60 3rd Edition and
UIQ 3 devices.

Windows Mobile (OS)
Windows Mobile was developed by Microsoft for smartphones and Pocket PCs. Windows Mobile was based on the
Windows CE kernel and first appeared as the Pocket PC 2000 operating system.
Development include writing native code with Visual C++, managed code that works with the .NET Compact
Framework, writing code in Tcl-Tk with eTcl, GCC using CeGCC., Python using PythonCE. or server-side code that
can be deployed using Internet Explorer Mobile or a mobile client on a user's device. The .NET Compact
Framework is a subset of the .NET Framework and hence shares many components with software development
on desktop clients, application servers, and web servers which have the .NET Framework installed, thus
integrating networked computing space
