Android Studio 2.0 RC 1 and Emulator 25.1 RC 1 are now available in the Beta channel. If you have 2.0 Preview or Beta installations, please update to RC 1 and let us know if you have any issues.

We have done extensive additional testing of both Android Studio and the Emulator. We have also verified these with a wide range of internal and external developers. We want to make sure we get Instant Run and the new emulator just right before promoting it to stable. Please continue to give us feedback and let us know if you run into any problems!  (via Help > Submit Feedback in Android Studio and For the Emulator In the tools menu select the three circles > Help > File a Bug.)

Android Studio RC 1

This build incorporates several more fixes for Instant Run, which is working at parity with 1.5.1. With Instant Run enabled (on by default), the first full build will be slightly slower than 1.5.1 as we create multiple dex files. Subsequent incremental builds will be much faster than 1.5.1. Full and incremental builds will be slightly faster than 1.5.1 even if you disable Instant Run due to optimizations we’ve made -- but enable Instant Run for max performance. If you want more information on Instant Run, be sure to check out the updated Instant Run documentation.

Reminder: If you want to test out Android N features, move to the Canary Channel and use Android Studio 2.1.

Emulator 25.1

Emulator 25.1 release candidate is also available in the SDK Preview channel. This version includes bug fixes to taking screenshots and our APK drag and drop installation onto the Emulator.

If you are using Android Studio 2.0+ you should be prompted to upgrade through the SDK manager or through the built-in Android Studio patch mechanism (Check for Updates).

Android Studio Installation

You can update your current 1.5 or 2.0 installation to 2.0 RC 1 by using the built-in patch mechanism (make sure you switch to the Beta channel first, if necessary.)

IF YOU WANT TO KEEP YOUR 1.5 STABLE VERSION AND RUN 2.0 STABLE SIDE BY SIDE READ ON. Patch-updating will replace the existing installation with a preview version. If you want to keep 1 stable version and also have 1 preview version, download a separate installation of 2.0 from the Android Studio 2.0 RC 1 page. You can keep 1.5 and 2.0 installed side by side; they use separate settings and cache directories.

Problems?

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