Android Studio 1.2 Preview 2 Available

We've just pushed a new build of Android Studio 1.2 to the canary channel. In addition to bug fixes from last week's canary build, there are some notable features for the Android support:

Performance tools: The memory usage window is now included as a tab in the Android runtime window, and there is now a tab for graphing CPU usage as well. You can drag these tabs to stack them vertically if you want to view both at the same time:
There's also a new "Captures" view which shows the various performance data files you've collected. From there you can open corresponding viewers, or in the case of .hprof files right click to convert it to a standard .hprof file format.
BCP 47 support. As of Lollipop, Android supports 3 letter language codes (as well as 3 letter region codes, additional script types etc using a resource folder format based on BCP 47). Android Studio 1.1 included some preliminary support for this, but it is more fully supported in Android Studio 1.2. (Note that you must use version 1.1 of the Gradle plugin or later as well.)  The resource chooser dialog now combines the language and region qualifiers into a single selection, you can choose any of the 3 letter languages (such as Klingon!) from the list, and we also show related regions when we have that information:
As always, please report bugs you find when testing our canary builds!

Installation
NOTE: Due to a bug, "Update & Restart" downloads the patch, but does not actually restart. Just manually exit the IDE, and start it again. Once you do that, the patch will be installed and the IDE updated.

You can use the update mechanism to update 1.2 alpha 1 to 1.2 alpha 2, as well as from 1.1 (stable)., provided you are using the canary channel (to change channels, open the preference dialog, go to the Updates category and change the channel setting). 

However, if you update from 1.1 to 1.2 alpha 2 note that this will replace your current installation, and you'll probably want to keep a stable version around until we reach beta. Therefore, you can also go to the Android Studio 1.2 Preview 2 page and download a separate copy of this build and unzip it next to your 1.1 installation.

Problems?
If you run into problems, be sure to check the Known Issues page which we'll update as necessary.
