Application Framework
Enable applications access data from other applications ,sharing
Providing access to non-code resources
Enables all applications to display alerts in the status bar
Manages the lifecycle of applications
Libraries
Written in C/C++ - System C Library(libc)
Display/Graphics(SGL)
Media Libraries
SQLite –RDB engine-light weight
LibWebCore–web browser engine–embeddable web
view
Linux Kernel
Linux Version 2.6
Security, Memory & Process Management
Proven driver model
Efficient computing resource management
Stable and proven OS for mobile platform
Android Runtime
Includes a set of core libraries that provides most
of the functionality-JAVA
Every Android application runs in its own process
Dalvik VM executes files in the (.dex) format
Device can run multiple VMs efficiently
Development Tools
The Android SDK includes a variety of custom tools that help you develop mobile
applications on the Android platform.Three of the most significant tools are:
1. Android Emulator -A virtual mobile device that runs on our computer -use to
design, debug, and test our applications in an actual Android run-time
environment
2. Android Development Tools Plugin -for the Eclipse IDE - adds powerful
extensions to the Eclipse integrated environment
3. Dalvik Debug Monitor Service (DDMS) -Integrated with Dalvik -this tool let
us manage processes on an emulator and assists in debugging
What makes android special?
A truly open, free development platform.
Handset makers can use and customize the
platform without paying loyalty.
Developers like it as platform is not locked.
Components can be replaced by improved
versions.
High quality graphics and sound.
Advantages
Open.
All applications are equal.
Breaking down boundaries.
Fast and easy development.
Disadvantages
Security.
