try this , I'm a newbie , working on this.
I'm packaging these tools for Gajj Distro,
For Precise
sudo add-apt-repository ppa:linuxgndu/gajj-sci
And for trusty
sudo add-apt-repository ppa:linuxgndu/adt-raring
sudo apt-get update
For Android Developers Tool
sudo apt-get install adt (Google may be ending eclipse plugin support, so this package may not be further maintained on this ppa, however you can check plugin updates from eclipse, using Help-> Install new software-> Then adding or selecting plugin repository.)
You also have to install Android-sdk
sudo apt-get install android-sdk
sudo sh /opt/android-sdk/install-sdk
(you may skip sudo sh /opt/android-sdk/install-sdk
if you are installing android studio, bcz studio will automatically find the sdk on installion(first startup or you can manually set the path).)
For Android Studio
sudo apt-get install android-studio
Note: You may want to lock package version from synaptic package manager (or any) to prevent from downloading large updates by this ppa, bcz patches provided by Google are very small. This ppa is meant for installation purpose only.
You can also help me testing my package builds, bcz i'm newbie i don't know that much about ppa & packaging.
Hope this is it what you were asking for. :)
