Install Android Studio on Ubuntu 15.10 64 bits
First, just in case, we going to install this libraries:
sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1
Now, we need to download the last version from google
unzip -e android-studio-ide-141.2456560-linux.zip
At the beginning we can see an alert: "IBus prior to 1.5.11 may cause input problem. See IDEA-78860 for details."
to fix it, you can go to: System Settings > Language Support
Now, change IBus to none
Now restart you system. Run again studio.sh. If you see a warning like this: " WARN - dea.updater.SdkComponentSource - Couldn't find existing SDK" or the setup fails with this message: "ignoring unknown package filter 'platform-tools'", means that you don't have android SDK installed.
Now, choose you favourite flauvor, install it and now re-run Android Studio and choose the folder that contains your SDK.
