Install Eclipse IDE on Fedora / Ubuntu

On Fedora you will get Eclipse Helios
yum install eclipse-jdt
On Ubuntu you will get Eclipse galileo
sudo apt-get install eclipse
This step will take time The total eclipse is nearly 250MB to download. In Fedora DVD the Eclipse RPM is there. So just have a look before trying to download.
Install Android SDK
Fedora
cd ~
gedit .bash_profile
PATH=$PATH:$HOME/AndroidSDK:$HOME/AndroidSDK/tools export PATH
Save The file
source ~/.bash_profile
Ubuntu
gedit .bash_aliases
PATH=$PATH:$HOME/AndroidSDK:$HOME/AndroidSDK/tools export PATH
Save the File and then
source ~/.bash_aliases
This will add the android sdk installation directory to the command search path of the environment variable.
To check it just
echo $PATH
will print the android path.
