Android Studio is a slightly heavy app, even in a machine
with reasonable specs it sometimes hangs, yet that would do the job, just don’t
run too many applications while you are working with studio. Moving on, I will
first talk about the system requirements which would be any modern system with at
least 2.5+GHz processor , a 4 Gb or above RAM(this is the minimum, please don’t
go below this it will kill your system).
However, for Linux users, it is recommended to install
Studio in 64 bit systems. But to install Studio which is a 32 bit application
in a 64 bit machine you need to have the 32-bit support library package ia32-libs.
For Ubuntu users, you can execute the below command:
sudo apt-get install ia32-libs
1)
Install Java Development Kit(JDK)
Download and install
the required JDK package from the below link which is apt for your system OS.
For windows , the JAVA_HOME environment variable. The steps
of which are:
- Open My
Computer.
- Go to
System Properties.
- Open
Advance system settings.
- Goto
Advanced Tab and Open Environmental Variables.
- Then
Click on New and Set Variable Name : Path and Set Variable
Value : C:\Program Files (x86)\Java\jdk1.7.0_25\bin (The Directory
In which JDK is installed.)
- Click
OK
Verify the JDK installation by typing
java -version
from the command prompt, it should output
java version "1.7.0_71"
Java(TM) SE Runtime Environment (build 1.7.0_71-b14)
Java HotSpot(TM) Client VM (build 24.71-b01, mixed mode,
sharing)
If it works properly, else it will show command not found
error
Install Android Studio
Install Android Studio from the below link
Go through the license agreement and download the file as
exe or zip. Install the exe file or unzip the zip file.
Run Android Studio, for the very first run you will get a
dialog prompting to import settings from
an existing installation, followed by the setup guide. Go through the guide and in the end press the
finish button.
Vola, you are done with the installation. Let’s start with
our first program with Studio, and when it comes to firsts in development it is
always Hello World.
On starting Studio, you will be greeted with a welcome
screen as follows
If you have already created projects it will be listed in
the Recent Projects tab.
Now starting fresh,
click on the Start a new Android Studio project and go through the guide.
You can give your project a name say “HelloWorld” in camel
case in the Application name field, also give a proper package name say ”com.example.firstproject.helloworld”
in lower case, click next.
Select your desired platform, say you are developing a mobile
app, select phone and tablet and also choose the minimum sdk version as to
which version of android release can support your app(its advised to choose the
lowest version, so that you app may run in most devices), click next.
Select a template, say Blank Activity. An activity is a code
to support the UI. It will help you to design your application to behave as you
wish in each lifecycle of the application like when the app is in foreground or
background etc. The next page allows you to name your project components such
as your activity, layout (a layout is view design on how you want to see each
activity in your device), click Finish.
The android studio opens up with a layout displayed in front
of you. You can see it contains a view with a label “Hello World”. In android
all activity layouts by default comes up this way, so for now just click the
play button on top if you have a device plugged in.
