Step
1 - Setup Java Development Kit (JDK)
You can download the latest version of Java JDK from Oracle's Java
site: Java SE Downloads. You will find instructions for installing JDK in
downloaded files, follow the given instructions to install and configure the
setup. Finally set PATH and JAVA_HOME environment variables to refer to the
directory that contains java and javac, typically
java_install_dir/bin and java_install_dir respectively.
If you are running Windows and installed the JDK in C:\jdk1.6.0_15,
you would have to put the following line in your C:\autoexec.bat file.
set PATH=C:\jdk1.6.0_15\bin;%PATH%
set JAVA_HOME=C:\jdk1.6.0_15
Alternatively, you could also right-click on My Computer, select Properties,
then Advanced, then Environment Variables. Then, you
would update the PATH value and press the OK button.
On Linux, if the SDK is installed in /usr/local/jdk1.6.0_15 and you
use the C shell, you would put the following code into your .cshrc file.
setenv PATH /usr/local/jdk1.6.0_15/bin:$PATH
setenv JAVA_HOME /usr/local/jdk1.6.0_15
Alternatively, if you use an Integrated
Development Environment (IDE) Eclipse, then it will know automatically where
you have installed your Java.
Step 2 - Setup Android SDK
You
can download the latest version of Android SDK from Android official website : Android SDK Downloads. If you are installing SDK on Windows machine, then you will
find a installer_rXX-windows.exe,
so just download and run this exe which will launch Android SDK Tool Setup wizard to guide you throughout of the installation,
so just follow the instructions carefully. Finally you will have Android SDK Tools installed on your
machine.
If
you are installing SDK either on Mac OS or Linux, check the instructions
provided along with the downloaded android-sdk_rXX-macosx.zip
file for Mac OS and android-sdk_rXX-linux.tgz
file for Linux. This tutorial will consider that you are going to setup your
environment on Windows machine having Windows 7 operating system.
So let's launch Android SDK Manager using the option All Programs > Android SDK Tools > SDK
Manager, this will give you following window:
Once
you launched SDK manager, its time to install other required packages. By
default it will list down total 7 packages to be installed, but I will suggest
to de-select Documentation for Android
SDK and Samples for SDK
packages to reduce installation time. Next click Install 7 Packages button to proceed, which will display following
dialogue box:
If
you agree to install all the packages, select Accept All radio button and proceed by clicking Install button. Now let SDK manager do
its work and you go, pick up a cup of coffee and wait until all the packages
are installed. It may take some time depending on your internet connection.
Once all the packages are installed, you can close SDK manager using top-right
cross button.
Step 3 - Setup Eclipse IDE
All the examples in this tutorial have been written using Eclipse
IDE. So I would suggest you should have latest version of Eclipse installed on
your machine.
To install Eclipse IDE, download the latest Eclipse binaries from http://www.eclipse.org/downloads/. Once you downloaded the installation, unpack the
binary distribution into a convenient location. For example in C:\eclipse on
windows, or /usr/local/eclipse on Linux and finally set PATH variable
appropriately.
Eclipse can be
started by executing the following commands on windows machine, or you can
simply double click on eclipse.exe
%C:\eclipse\eclipse.exe
Eclipse can be started by executing the following commands on Linux
machine:
$/usr/local/eclipse/eclipse
After a successful startup, if everything is fine then it should
display following result:
Step 4 - Setup Android
Development Tools (ADT) Plugin
This
step will help you in setting Android Development Tool plugin for Eclipse.
Let's start with launching Eclipse and then, choose Help > Software Updates > Install New Software. This will
display the following dialogue box.
Now
use Add button to add ADT Plugin as name and https://dl-ssl.google.com/android/eclipse/
as the location. Then click OK to add this location, as soon as you will click
OK button to add this location, Eclipse starts searching for the plug-in
available the given location and finally lists down the found plugins.
Now
select all the listed plug-ins using Select
All button and click Next
button which will guide you ahead to install Android Development Tools and
other required plugins.
Step 5 - Create Android Virtual
Device
To
test your Android applications you will need a virtual Android device. So
before we start writing our code, let us create an Android virtual device.
Launch Android AVD Manager using Eclipse menu options Window > AVD Manager> which will launch Android AVD Manager.
Use New button to create a new
Android Virtual Device and enter the following information, before clicking Create AVD button.
If
your AVD is created successfully it means your environment is ready for Android
application development. If you like, you can close this window using top-right
cross button. Better you re-start your machine and once you are done with this
last step, you are ready to proceed for your first Android example but before
that we will see few more important concepts related to Android Application Development.
