Now a days Android Rocks. Over 3 Lakhs Phones powers everyday. Over One Lakh Free Applications to download from Android Market. And Android development will became a hot topic. Android is powered By Open Handset Alliance. Compared to Iphone development Android development is less costly. Only need Android Emulator environment and Java. Eclipse IDE will do the whole work as well.
Just have a look how to setup a development environemnt in Fedora 14/ Ubuntu 10.10 for android development.
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.
