programming language.

Application framework

• Framework elements are: Intents , Content Providers , Views and managers

• This layer has been designed to facilitate the reuse of components in android

• Developers can build their applications to execute on android kernel and inter-operate among themselves and with existing applications

Linux kernel• Android relies on Linux version 2.6 for core

system services such as device drivers, security, memory management ,process management.

• The kernel also acts as an abstraction layer between the hardware and the rest of the various softwares.

Dalvik virtual machine

• Dalvik is the process virtual machine(VM) in google’s android operating system.

• Dalvik ,like the rest of android,is a open-source software.it was originally written by Dan Bornstien , who named it after the fishing village of Dalvik in Iceland.

How does android manages memory

• Android’s process and memory management is a little unusual. Like Java and .NET, Android uses its own run time and virtual machine to manage application memory.

• Each Android application runs in a separate process within its own Dalvik instance.

• Android manages opened applications which are running in the background, so officially you shouldn’t care about that.

How is android Enviroment growing

•Google's Android was expected to become the world's second most-used smart phone OS by 2012, after the Symbian OS.

•5 months ago 200,000 Android devices were activated each day. Today, it’s 350,000 per day. In fact for every baby born in the U.S. each day, 30 Android devices are activated.

•Now Android OS is running on several no of devices .

Disadvantages of android

• Chaos ecological system.• In case of hack system it leads to serious

measures to lock the device• It is expensive compared to windows.• Android depend upon certain use such as

bluetooth , wifi , camera , GPS and compass etc.

Conclusion

• Android is a truly open, free development platform based on Linux and open source. Handset makers can use and customize the platform without paying a royalty.

• A component-based architecture inspired by Internet mash-ups. Parts of one application can be used in another in ways not originally envisioned by the developer. can even replace built-in components with own improved versions. This will unleash a new round of creativity in the mobile space.

• Android is open to all: industry, developers and users • Participating in many of the successful open source projects • Aims to be as easy to build for as the web. • Google Android is stepping into the next level of Mobile Internet
