If you are able to download an update of Android Studio, but after it restarts nothing happens, check out the following example:
cd ~/android-studiobin subfolder:
cd binstudio.sh file has run permissions:
chmod +x studio.sh./studio.shAfter that Android Studio will find the patch and install it. Then you may close Android Studio and run it the regular way (whatever way you prefer, I run it from Launcher pad).
