It helps to manage security, memory management, process management, network stack and other important issues.
User should bring Linux in his mobile device as the main operating system.
Android RuntimeIt was designed specifically for Android
running in limited environment.
Which converts generated byte code from .jar to .dex file.
Conversion From .jar to .dex
.java
.class .jar .dex
LibrariesSet of native libraries written in C/C++.
They are responsible for stable performance of various components.
Surface Manager is responsible for composing different drawing surfaces on the mobile screen.
Application Framework Application Framework is written in Java language.
It is a toolkit that all applications use. It has several components.
The Activity Manager manages the life circle of the applications and provides a common navigation back stack for applications
The Package Manager keeps track of the applications, which are installed in the device.
Development ToolsJavaAndroid SDK:-
Class Library Developer Tools Emulator and System Images Documentation and Sample Code
Eclipse IDE + ADT (Android Development
Tool) Reduces Development and Testing Time Makes User Interface-Creation easier Makes Application Description Easier
