Posted by, Jamal Eason, Product Manager, Android

One the most requested features we receive is to make app builds and deployment faster in Android Studio. Today at the Android Developer Summit, we're announcing a preview of Android Studio 2.0 featuring Instant Run that will dramatically improve your development workflow. With Android Studio 2.0, we are also including a preview of a new GPU Profiler.

All these updates are available now in the canary release channel, so we can get your feedback. Since this initial release is a preview, you may want to download and run an additional copy of Android Studio in parallel with your current version.

New Features in Android Studio 2.0

Instant Run: Faster Build & Deploy

Android Studio's instant run feature allows you to to quickly see your changes running on your device or emulator.

Getting started is easy. If you create a new project with Android Studio 2.0 then your projects are already setup. If you have a pre-existing app open Settings/Preferences, the go to Build, Execution, Deployment → Instant Run. Click on Enable Instant Run... This will ensure you have the correct gradle plugin for your project to work with Instant Run.

Enable Instant Run for Android Studio projects

Select Run as normal and Android Studio will perform normal compilation, packaging and install steps and run your app on your device or emulator. After you make edits to your source code or resources, pressing Run again will deploy your changes directly into the running app.

GPU Profiler

Profiling your OpenGL ES Android code is now even easier with the GPU Profiler in Android Studio. The tool is in early preview, but is very powerful and not only shows details about the GL State and Commands, you can record entire sessions and walk through the GL Framebuffer and Textures as your app is running OpenGL ES Code.

Whats Next

This is just a taste of some of the bigger updates in this latest release of Android Studio. We'll be going through the full release in more detail at the Android Developer Summit (livestreamed on Monday and Tuesday). Over the next few weeks, we'll be showing how to take advantage of even more features in Android Studio 2.0, so be sure to check back in.

Android Studio 1.5

Posted by, Jamal Eason, Product Manager, Android

Android Studio 1.5 is now available in the stable release channel. The latest release is focused on delivering more stability, with most of the enhancements being made under the hood (along with addressing several bugs).

Some of the specific bug fixes, include the ability to use short names when code-completing custom views.

In addition to the stability improvements and bug fixes, we've added a new feature to the memory profiler. It can now assist you in detecting some of the most commonly known causes of leaked activities.

There are also several new lint checks. Here's one below which warns you if you are attempting to override resources referenced from the manifest.

If you're already using Android Studio, you can check for updates from the navigation menu (Help → Check for Update [Windows/Linux] , Android Studio → Check for Updates [OS X]). For new users, you can learn more about Android Studio, or download the stable version from the Android Studio site.

As always, we welcome your feedback on how we can help you. You can also connect with the Android developer tools team via Google+. And don't worry about what's in the box from the video. It's nothing. Really. Forget I mentioned it.
