Android platform is based on Linuxtechnology.
Composed of OS, user interface andapplication components.
Its issuance breaks the monopoly status ofMicrosoft windows mobile OS and NokiasSymbian OS.
Allows anyone to develop him ownapplications.
User is likely to download and installmalicious softwares written by softwarehackers.

Android PlatformArchitecture
Android has built in tools.
Android platform composed of Linuxkernel, system libraries, android runtime, application framework and so onfive parts.
-
Linux kernel
Android relies on Linux 2.6 version It provides core system services
security,memory management, processmanagement, network group, driven model.
The core part is equivalent to an abstract levelbetween the hardware layer and other softwarein the systems.
-
Libraries
Android includes a set of C/C++ libraries. Androids core libraries provide most of the
function to the Java class libraries.
-
Android runtime Android runtime consists of two
components. First, a set of core libraries. Second, the Virtual machine Dalvik. Java programs are received and
translated by the VM Dalvik. Applications will be encapsulated in
Dalvik. A VM is available for each and every
program even if some programs arerunning in parallel.
-
Application Framework
An application framework is a softwareframework that is used to implement a standardstructure of an application for a specific OS.
Any application can publish its own features. These functions can be used by any other
application.
-
Applications
Applications are written in Java programminglanguage.
The Android SDK tools compile the code into anandroid package,an archive file with a .apksuffix.
The android software platform come with a set ofbasic applications.
These applications can run simultaneously.
-
Important Features Application framework Dalvik VM Integrated browser Optimized graphics SQLite Media support GSM telephony Bluetooth,EDGE,3G and WiFi Camera,GPS,compass and accelerometer Rich development environment.
-
Android SystemSecurity
In the default settings, no application haspermission to perform any operations thatwould adversely impact other applications,the OS, or the user.
Androids security mechanism is mainlyreflected in 2 aspects:Android systemsecurity and data security.
-
Android system securityprotection
Android system safety inherited the design ofLinux in the design ideology.
In practice, each Android application runs in itsown process.
In the OS, each application runs with a uniquesystem identity.
Most of the security functions are provided bythe permission mechanism.
Permission can be restricted to particularspecific process operations.
-
Android data securityprotection
Android is privilegeseparated.
Data security mainlyrelies on softwaresignaturemechanism.
-
It uses AndroidManifest.xml file When specified software services are
called,the system first checks this file. To make use of protected features of the
device, one must include inAndroidManifest.xml,one or more tags declaring thepermissions.
