1) Check in System Settings -> Details, whether your Ubuntu is 32-bit or 64-bit
2) If your Ubuntu is a 32-bit OS then run this sudo apt-get install libgl1-mesa-dev
In case of 64-bit OS run this sudo apt-get install ia32-libs
3) run this sudo apt-get install openjdk-6-jdk
or better this sudo apt-get install openjdk-7-jdk
4) Download SDK platform tools from here http://developer.android.com/sdk/index.html
5) Unzip downloaded file "adt-bundle-linux-x86_64-20131030.zip" (you can have a little bit different name ;). But you should get folder contained two sub folder - sdk and eclipse
6) Run this nautilus ~
7) In opened window create folder 'android-sdk-linux'
8) copy the all entire contents of folder sdk (from unzipped archive) to this new folder 'android-sdk-linux'
9) try run this cd ~/android-sdk-linux/tools
then this ./android
. If you did all right you should see Android SDK Manager
10) run this sudo gedit ~/.bashrc
in opened editor add this in very top
#AndroidDev PATH
export PATH=${PATH}:~/android-sdk-linux/tools
export PATH=${PATH}:~/android-sdk-linux/platform-tools
11) save and close
12) run exec bash
then try run android
13) give write permissions to android-sdk-linux folder
Enjoy! ;)
