The minimum system requirements are: JDK, JRE,

Android SDK

STEP 1:

1. Installing JRE (Java Run Time Environment) It Covers end-users need. Contains everything required

to run Java applications on your system.

For checking whether Java is installed properly click on

the following link:

Java Verifier

http://www.java.com/en/download/installed.jsp

Click on Verify Java Version.

Link will verify the version of java.

STEP 3

3. Downloading & Installing the Android SDK The Android SDK provides you the API libraries and developer

tools necessary to build, test, and debug apps for Android.

Link : http://developer.android.com/sdk/index.html#download

With a single download, the ADT Bundle includes everything youneed to begin developing apps:

Eclipse + ADT plugin

Android SDK Tools

Android Platform-tools

The latest Android platform

The latest Android system image for the emulator
http://developer.android.com/sdk/index.htmlhttp://developer.android.com/sdk/index.html


10/39


11/39

Once the software is downloaded unzip the sdk.

Open the Eclipse folder and install Eclipse. Aworkspace launcher will pop up and Select ok to create

a Workspace.

Open the folder: adt-bundle-windows-x86-

20130219\sdk\tools

Double click Android. This will install the Android

SDK Manager

The Android SDK separates tools, platforms, and othercomponents into packages you can download using the

SDK Manager.


12/39


13/39

srcyour source code

genauto-generated code (usually just R.java)

Included libraries

Resources Drawables (like .png images)

Layouts

Values (like strings)

Manifest file


14/39

Used to define some of the resources Layouts (UI)

Strings

Manifest file

Preferred way of creating UIs Separates the description of the layout from any actual code

that controls it

Can easily take a UI from one platform to another


15/39

Auto-generated: never edit this file

Contains IDs of the project resources

Enforces good software engineering

Use findViewById and Resources object to get access

to the resources

Ex. Button b = (Button)findViewById(R.id.button1)

Ex. getResources().getString(R.string.hello));


16/39

Eclipse has a great UI creator Generates the XML for you

Composed of Viewobjects

Can be specified for portrait and landscape mode

Use same file name, so can make completely different UIs for

the orientations without modifying any code


17/39


18/39

Click Create to make layout modifications.

When in portrait mode can select Portrait to make a res sub

folder for portrait layouts

Likewise for Landscape layouts while in landscape mode

Will create folders titled layout-port and layout-land


19/39

Note: these port and land folders are examples ofalternate layouts, see here for more info http://developer.android.com/guide/topics/resources/providing-resources.html

Avoid errors by making sure components have the same id in

both orientations, and that youve tested each orientation

thoroughly

20/39


21/39

In res/values

strings.xml

Application wide available strings

Promotes good software engineering

UI components made in the UI editor should havetext defined in strings.xml

Strings are just one kind of Value there are manyothers


22/39

Contains characteristics about your application

When have more than one Activity in app, NEED to

specify it in manifest file

Go to graphical view of the manifest file

Add an Activity in the bottom right

Browse for the name of the activity

Need to specify Services and other components too

Also important to define permissions and external

libraries, like Google Maps API

Activity

Service

Android in a nutshell:

25/39

The basis of android applications A single Activity defines a single viewable screen

the actions, not the layout

Can have multiple per application

Each is a separate entity They have a structured life cycle

Different events in their life happen either via the usertouching buttons or programmatically


26/39


27/39

Run in the background

Can continue even if Activity that started it dies

Should be used if something needs to be done while the user isnot interacting with application

Otherwise, a thread is probably more applicable

Should create a new thread in the service to do work in, sincethe service runs in the main thread


28/39

Can be bound to an application It terminates when all applications bound to it unbind

Allows multiple applications to communicate with it via acommon interface

Needs to be declared in manifest file

Like Activities, has a structured life cycle


29/39


30/39

A bound service is the serverin a client-serverinterface.

A bound service allows components (such as activities)

to bind to the service, send requests, receive

responses, and even perform interprocess

communication (IPC).

A bound service typically lives only while it serves

another application component and does not run in thebackground indefinitely.


31/39

In this case, an application component starts theservice, and it would continue to run in the background,

even if the original component that initiated it is

destroyed.

For instance, when started, a service would continue to

play music in the background indefinitely.


32/39

Similar to launching a regular Java app, use the launch

configurations

Specify an Android Application and create a new one

Specify activity to be run

Can select a manual option, so each time program isrun, you are asked whether you want to use the actual

phone or the emulator Otherwise, it should be smart and use whichever one is

available


33/39


34/39


35/39


36/39

Should be enabled on phone to use developer features

In the main apps screen select Settings -> Applications

-> Development -> USB debugging (it needs to be

checked)


37/39

Used for a wide variety of developer tasks Read from the log file

Show what android devices are available

Install android applications (.apk files)

In the platform-tools directory of the main androidsdk directory

Recommend putting this directory and the tools directory on

the system path

adb.exe


38/39

Instead of using traditional System.out.println, use the Log

class Imported with android.util.Log Multiple types of output (debug, warning, error, ) Log.d(,)

Can be read using logcat.

Print out the whole log, which auto-updates adb logcat

Erase log adb logcatc

Filter output via tags adb logcat : *:S can have multiple : filters corresponds to debug, warning, error, etc. If use Log.d(), then = D


39/39

One option: Android Screen Capture http://www.mightypocket.com/2010/08/android-screenshots-

screen-capture-screen-cast/

Its slow, but fine for screenshots of applications whose screensarent changing fast
