Download the Linux SDK from the Android website.
Copy the folder to whereever you want to extract the contents.
Open a terminal there, and then run:

sudo apt-get install unzip
sudo tar xvzf android-studio-ide-135.1641136-linux.zip
cd android-studio-ide-135.1641136-linux
./studio.sh

JDK 1.7 is required for Studio 1.0 onwards:

1. Download the ubuntu zip from the d.android.com and repeat the steps from above
2. Download the jdk 1.7 by executing the following commands in terminal as mentioned webupd8:

   sudo add-apt-repository ppa:webupd8team/java
   sudo apt-get update
   sudo apt-get install oracle-java7-installer
   

3. Open Android Studio and install the SDK tools.

Caveats:

1. If your system has a 32 bit processor, use Platform Tools r23.0.1.
   Refer to this bug for details.

Below are the steps to install Android Studio in Ubuntu system:

1. Install JDK 6 or later

First, install Oracle JDK 8 (although you could also choose OpenJDK but it has some UI/performance issues) using WebUpd8 PPA.

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java8-installer
sudo apt-get install oracle-java8-set-default

To make sure, it’s installed successfully, open a terminal and type (you should get the version number of the jdk you’ve installed e.g javac 1.8.0_11)

javac -version

2. Download and install Android Studio

Download the Android Studio package for Linux and extract it somewhere (e.g home directory).
Then type :

cd android-studio/bin
./studio.sh

3. Install SDK Platforms

You need to install some SDK before you jump into building android apps. Click on Configure -> SDK Manager to open Android SDK Manager. Select the latest API (to test against target build, e.g API 19 (Android 4.4.2)) and some packages in Extras (Android Support Library and Android Support Repository). Then install the selected packages.

Run the following command on terminal.

sudo apt-add-repository ppa:paolorotolo/android-studio
sudo apt-get update
sudo apt-get install android-studio

Here’s how I installed android studio on xubuntu.

1. Install JDK:

Go through following commands to install jdk

sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
sudo apt-get install oracle-java7-installer
sudo apt-get install oracle-java7-set-default

If you want to install other version of jdk than replace your version number with 7 in last two commands.

2. Download the latest android studio from official site:
https://developer.android.com/studio/index.html

It is better to use latest version of android studio because I tried to install version 1.5.1 and it was not working. Then I installed version 2.1.1 and it run perfectly.

3. Extract downloaded android studio file in whichever folder you want.
   Now go to extracted android studio–>bin directory and open terminal here. Now run following:./studio.sh

And that’s it. If you are facing any problem than comment below.

Android Studio PPA is maintained by Paolo Rotolo. We just need to add PPA to our system and install it using the following commands:

$ sudo add-apt-repository ppa:paolorotolo/android-studio
$ sudo apt-get update
$ sudo apt-get install android-studio

I was just investigating this issue now, you should use Ubuntu Make

Which “is a command line tool which allows you to download the latest version of popular developer tools on your installation”
