Installing NetBeans and Android SDK on Ubuntu

I had many issues in developing Google Map application using Fatdog64+NetBeans+AndroidSDK, so I try another option: Ubuntu64+NetBeans+AndroidSDK following instructions at http://askubuntu.com/questions/318246/complete-installation-guide-for-android-sdk-adt-bundle-on-ubuntu

(3)Download Android SDK for linux (android-sdk_r24.4.1-linux.tgz and run tar xvzf android-sdk_r24.4.1-linux.tgz to install the package.
