I have to install Android Studio on Ubuntu and I have used this link to download Android Studio.
Is there any easy way to install Studio on Ubuntu?
You could always follow the official guide on how to install Android Studio on Linux. There's even a video you can watch!

Remember to select Linux in the drop-down box.
To summarise the steps: download Android Studio and extract it and execute studio.sh to run it. If you're running 64-bit Ubuntu, you will need to run:
sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6
