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)
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.
