I am a android developer, I recently installed ubuntu in my another desktop that is 32 bit.

I installed ubuntu 14.04 LTS

When I am going to make a virtual android device through eclipse+android sdk, it's not running. It's saying me to update into 64bit.

Can anyone please give me a solution, how can I run it or update to 64bit from 32bit.

Thanks in Advance.

You cannot do it in simple way. What I would do is to save the content of /home and the /etc, afterwards make a list of installed packages with: 

dpkg --get-selections > ~/Package.list
sudo cp -R /etc/apt/sources.list* ~/
sudo apt-key exportall > ~/Repo.keys

After that save somewhere the created files, and reinstall your Ubuntu choosing the 64bit version. When finished with basic install, copy back the /home and /etc, and restore the packages you had before with:

sudo apt-key add ~/Repo.keys
sudo cp -R ~/sources.list* /etc/apt/
sudo apt-get update
sudo apt-get install dselect
sudo dpkg --set-selections < ~/Package.list
sudo apt-get dselect-upgrade -y

Ofcourse adjust the paths of your backed up files.
