@soepono 19
@soepono 20
Android S/W Stack - Application
• This layer is basic smartphone functions such as calling, SMS, etc (end user)
• Provides a set of core applications: Email Client, SMS Program, Calendar, Maps, Browser, Contacts, Etc
• All applications are written using the Java language.
• 4 basic block application – Activities: application that show on the screen
– Intents: movement mechanism from an activity to another activity
– Services: program that runs in the background
– Content Provider: sharing information
@soepono 21
Android S/W Stack – App Framework
• Program for manage basic functions of smartphones
• Enabling and simplifying the reuse of components Developers have full access to the same
framework APIs used by the core applications.
Users are allowed to replace components.
@soepono 22
Android S/W Stack – App Framework (Cont)
• Features
Feature Role
View System
Used to build an application, including lists, grids, text boxes, buttons, and embedded web browser
Content Provider

Android S/W Stack – Runtime (Cont)
• Dalvik Virtual Machine
Providing environment on which every Android application runs
Each Android application runs in its own process, with its own instance of the Dalvik VM.
Dalvik has been written such that a device can run multiple VMs efficiently.
Register-based virtual machine
@soepono 26
Android S/W Stack – Runtime (Cont)
• Dalvik Virtual Machine (Cont) Executing the Dalvik Executable (.dex) format
.dex format is optimized for minimal memory footprint.
