13. Android Architecture
-This layer is the top layer of the architecture.
-In this layer we find application that ship with the android device
application such as phone , contacts etc.
-This layer also ship with the application downloaded from android
15. Application framework
-Framework elements are-intent, content providers , views and
-this layer has been designed for facilitate the reuse of component in
This layer contains all the code that provides main features
of the android OS.
17. Android Runtime
-At the same level of libraries.
- Application Developed language : Java
-Dalvik Virtual Machine
Instruction set : Dalvik Executable.
-Java Standard Library
Compile java code to Dalvik Executable
18. Linux kernal
Android is based on the Linux Kernel. This layer contains the low level
As a IDE(integrated development environment) android
Eclipse is multi language development environment,
develop many applications using various languages such as
java, c , cpp etc.
For android development we should have eclipse IDE for
java EE developers.
Six editions are available such as windows(32 and 64 bit),
Linux(32 and 64 bit) etc.
21. Android SDK
SDK stands for software development kit.
A SDK that enables developers to create application for the
The Android SDK includes sample projects with source code
, development tools, an emulator , documentation ,
tutorials and required libraries to build Android applications.
We can download SDK from
ADT stands for android development tools.
ADT plug-in for eclipse is an extension to the eclipse IDE
that supports the creation and debugging of apps.
Using ADT in eclipse we can(a) Create new android app.
(b) Access the tools for accessing our android emulators and
(c) Compile and debug android app.
(d) Export android apps into APK.
Android application may be run on a real device or on the android
emulator , which ships with the android SDK
DVM is open source software.
DVM stands for Dalvik virtual machine Google's Android
It is the software that runs the apps on Android devices.
Dalvik is thus an integral part of Android, which is typically
used on mobile devices such as mobile phones and tablet
25. Steps of creating new
To creating new android project select-project.
Give project name then select finish.
Then do coding in .java file, layout file, main XML file.
After completion project is ready to run on emulator.
Then run it thorough selecting run as –android project.
Then project runs on android emulator.
An activity is a single, focused thing that the user can do.
Almost all activities interact with the user, so the Activity
class takes care of creating a window for us in which we
can place our UI with setContentView(View).
Activity life cycle-Activities in the system are managed as
an activity stack. When a new activity is started, it is
placed on the top of the stack and becomes the running
activity -- the previous activity always remains below it in
the stack, and will not come to the foreground again until
the new activity exits.
During my training I create android project “phonebook”.
28. Introduction to the project
This project aims at storing our important contacts on our
This application is mainly designed for those who want to
store there important contacts on their mobile device itself.
29. SOME SPECIAL FEATURES
We can create , delete , view and search our contacts
which we have stored earlier.
It helps in easily remembering our important contacts
which we want to use in our daily work.
In this project we can easily set our important contact
details like birthday , email address , home and office
phone number separately and much more .
