2. Setup environment variables and JAVA_HOME

Create a file /etc/profile.d/oraclejdk.sh with the following content (adapt the paths to reflect the path where you stored your JDK):

export J2SDKDIR=/usr/lib/jvm/oracle_jdk8
export J2REDIR=/usr/lib/jvm/oracle_jdk8/jre
export PATH=$PATH:/usr/lib/jvm/oracle_jdk8/bin:/usr/lib/jvm/oracle_jdk8/db/bin:/usr/lib/jvm/oracle_jdk8/jre/bin
export JAVA_HOME=/usr/lib/jvm/oracle_jdk8
export DERBY_HOME=/usr/lib/jvm/oracle_jdk8/db


3.  Execute [android SDK root]/tools/android sdk and add necessary packages

INSTALLATION INSTRUCTIONS
===============================================================================

  Linux Installation Instructions
  ------------------------------------------------------------------------------
  1. Unpack the Android Studio distribution archive that you downloaded to
     where you wish to install the program. We will refer to this destination
     location as your {installation home} below.

  2. Open a console and cd into "{installation home}/bin" and type:

       ./studio.sh

     to start the application.

  3. [OPTIONAL] Add the "{installation home}/bin" to your PATH environmental
     variable so that you may start Android Studio from any directory.

  4. [OPTIONAL] To adjust the value of JVM heap size open android studio.vmoptions
     (android studio64.vmoptions for 64-bit JDK), and modify the -Xms and -Xmx parameters.


  [OPTIONAL] Changing location of "config" and "system" directory
  ------------------------------------------------------------------------------
  By default Android Studio stores all your settings under ~/.AndroidStudio/config directory
  and stores data cache under ~/.AndroidStudio/system directory.
  If you want to change these settings,

  1. Open a console and cd into "{installation home}/bin"

  2. Open file "idea.properties" in an editor. You should find strings like

     idea.system.path=~/.AndroidStudio/system

     and

     idea.config.path=~/.AndroidStudio/config

     and change them.

  3. Note that we recommend to store data cache ("system" directory) at a disk
     with at least 1G bytes free space

Enjoy!

5. First time execute Android Studio, you may encounter a problem.

"Unable to run mksdcard SDK tool."

The following solution works for me
 http://askubuntu.com/questions/147400/problems-with-eclipse-and-android-sdk

sudo apt-get install -y libc6:i386 libgcc1:i386 libstdc++6:i386 libz1:i386

6. Remember to change the Android SDK path in Android Studio.
    Or it will download the SDK again under ~/Android.
