A Java ME implementation — Android applications are written using the Java language,
but they are not run within a Java ME (Mobile Edition) VM, and Java-compiled classes and
executables will not run natively in Android.
Part of the Linux Phone Standards Forum (LiPS) or the Open Mobile Alliance (OMA) —
Android runs on an open-source Linux kernel, but, while their goals are similar, Android’s
complete software stack approach goes further than the focus of these standards-defining
organizations.
Simply an application layer (such as UIQ or S60) — Although Android does include an application
layer, “Android’’ also describes the entire software stack, encompassing the underlying
operating system, the API libraries, and the applications themselves.
A mobile phone handset — Android includes a reference design for mobile handset manufacturers,
but there is no single “Android phone.” Instead, Android has been designed to support
many alternative hardware devices.
Google’s answer to the iPhone — The iPhone is a fully proprietary hardware and software
platform released by a single company (Apple), whereas Android is an open-source
software stack produced and supported by the Open Handset Alliance (OHA) and designed
to operate on any compatible device. [import]uid: 175437 topic_id: 31216 reply_id: 331216[/import]
Android has expanded beyond a pure mobile phone platform to provide a development
platform for an increasingly wide range of hardware, including tablets and televisions.
Put simply, Android is an ecosystem made up of a combination of three components:
A free, open-source operating system for embedded devices
An open-source development platform for creating applications
Devices, particularly mobile phones, that run the Android operating system and the applications
created for it
Android is made up of several necessary and dependent parts, including the
following:
A Compatibility Definition Document (CDD) and Compatibility Test Suite (CTS) that
describe the capabilities required for a device to support the software stack.
A Linux operating system kernel that provides a low-level interface with the hardware, memory
management, and process control, all optimized for mobile and embedded devices.
Open-source libraries for application development, including SQLite, WebKit, OpenGL, and
a media manager.
A run time used to execute and host Android applications, including the Dalvik Virtual
Machine (VM) and the core libraries that provide Android-specific functionality. The run
time is designed to be small and efficient for use on mobile devices.
An application framework that agnostically exposes system services to the application layer,
including the window manager and location manager, databases, telephony, and sensors.
A user interface framework used to host and launch applications.
A set of core pre-installed applications.
Native Android Applications x 5
A software development kit (SDK) used to create applications, including the related tools,
plug-ins, and documentation. [import]uid: 175437 topic_id: 31216 reply_id: 125258[/import]
--------------Types of Android Applications------------------
Most of the applications we create in Android will fall into one of the following categories:
Foreground Applications — The application which is only useful when appears on the screen and if it is suspended will not be visible like Game apps.
Background Application — These type of application only works at background of phone software. It does not show their visibility, most of its lifetime hidden like alarm clock.
Intermittent Applications — It works at both foreground and background. This type of application do most of their work in the background. Most well-designed applications fall into this category. A common example would be a media player.
Widgets and Live Wallpapers Apps — Some applications are represented only as a home-screen Widget or as a Live Wallpaper. [import]uid: 175437 topic_id: 31216 reply_id: 125396[/import]
Following are the preinstalled applications in almost all the android devices which makes it open source project:
E-mail client
SMS management application
A full PIM (personal information management) suite, including a calendar and contacts list
WebKit-based web browser
music player and picture gallery
camera and video recording application
calculator
home screen
alarm clock
Few devices also offers Google Mobiel applications like:
Google Play Store for downloading third-party Android applications
Google Maps application, including StreetView, driving directions,
and turn-by-turn navigation, satellite views, and traffic conditions
Gmail
Google Talk
YouTube
Note: Some devices can have more than these apps. [import]uid: 175437 topic_id: 31216 reply_id: 125548[/import]
