Android Studio 1.0 Release Candidate 3 Released

We've just released Android Studio 1.0 Release Candidate 3 to the canary and beta channels. This fixes a number of bugs reported against RC 2 and updates to the latest Gradle plugin.

One frequent problem users have reported is that editing, idea.vmoptions or Info.plist for various reason (e.g. to tweak the VM heap size, or to switch to a different version of the JDK, etc) has resulted in patch update warnings.

As of RC 3, we have a better mechanism for customizing properties for the launchers on all three platforms. You should not edit any files in the IDE installation directory. Instead, you can customize the attributes by creating your own .properties or .vmoptions files in the following directories. (This has been possible on some platforms before, but it required you to copy and change the entire contents of the files. With the latest changes these properties are now additive instead such that you can set just the attributes you care about, and the rest will use the defaults from the IDE installation).

  • %USERPROFILE%\.AndroidStudio\studio[64].exe.vmoptions
  • %USERPROFILE%\.AndroidStudio\
  • ~/Library/Preferences/AndroidStudio/studio.vmoptions
  • ~/Library/Preferences/AndroidStudio/
  • ~/.AndroidStudio/studio[64].vmoptions
  • ~/.AndroidStudio/
You can also place use environment variables to point to specific override files elsewhere:
  • STUDIO_VM_OPTIONS, which vmoptions file to use
  • STUDIO_PROPERTIES, which property file to use
  • STUDIO_JDK, which JDK to run studio with
Note that this last variable allows you to for example run Android Studio with Java 7 on OSX (which normally picks Java 6 from the version specified in Info.plist):
$ export STUDIO_JDK=/Library/Java/JavaVirtualMachines/jdk1.7.0_67.jdk
$ open /Applications/Android\

This version is only available in both the canary channel and the beta channel. For Windows you can also download and test our new installer. 

NOTE: If you are in the beta channel, you cannot update directly from 0.8.14 to 1.0 RC3; you have to first install 0.9.9 (which is virtually identical to 1.0 RC3, except for the version number), and from there you can update to 1.0 RC3. The reason for this is that the update mechanism used to not offer updates to versions with a different major version (e.g. 0.8 to 1.0). We've removed that restriction in 0.9.9, so once you patch from 0.8 to 0.9 you can then update to 1.0.

Visit the 1.0 RC 3 page for download links.

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