The download page for Android Studio does not list any repositories, it only offers direct download links. I noticed that there are many Android SDK and tools packages in the Ubuntu repos, but no Android Studio. Is there a frequently updated repository or PPA available for Android Studio?
This question was asked a long time ago back when Android Studio was still in a preview state, however, the answers are all very different and many of the answers consist of custom PPAs, many of which probably do not exist anymore for modern versions of Ubuntu. Therefore, this question needs to be re-asked so that we can collect updated instructions.
