Android Studio 2.2 is available to
Previewed at Google I/O 2016, Android Studio 2.2 is the latest release of our
IDE used by millions of Android developers around the world.
Packed with enhancements, this release has three major themes: speed, smarts,
and Android platform support. Develop faster with features such as the new
Layout Editor, which makes creating an app user interface quick and intuitive.
Develop smarter with our new APK analyzer, enhanced Layout Inspector, expanded
code analysis, IntelliJ�s 2016.1.3 features and much more. Lastly, as the
official IDE for Android app development, Android Studio 2.2 includes support
for all the latest developer features in Android 7.0 Nougat, like
completion to help you add Android platform features like
support,
Settings API, or the redesigned
and of course, the built-in
Emulator to test them all out.
In this release, we evolved the Android Frameworks and the IDE together to
create the Constraint Layout. This powerful new layout manager helps you design
large and complex layouts in a flat and streamlined hierarchy. TheConstraintLayout integrates into your app like a standard Android
support library, and was built in parallel with the new Layout Editor.
Android Studio 2.2 includes 20+ new features across every major phase of the
development process: design, develop, build, & test. From designing UIs with
the new ConstraintLayout, to developing C++ code with the Android
NDK, to building with the latest Jack compliers, to creating Espresso test cases
for your app, Android Studio 2.2 is the update you do not want to miss. Here�s
more detail on some of the top highlights:
Design
- Layout Editor: Creating Android app user interfaces is now
easier with the new user interface designer. Quickly construct the structure of
your app UI with the new blueprint mode and adjust the visual attributes of each
widget with new properties panel.
more.
Layout Editor
- Constraint Layout: This new layout is a flexible layout
manager for your app that allows you to create dynamic user interfaces without
nesting multiple layouts. It is backwards compatible all the way back to Android
API level 9 (Gingerbread). ConstraintLayout works best with the new Layout
Editor in Android Studio 2.2.

Develop
- Improved C++ Support: You can now use
or ndk-build to compile your C++ projects from Gradle. Migrating projects
from CMake build systems to Android Studio is now seamless. You will also find
C++ support in the new project wizard in Android Studio, plus a number of bug
fixes to the C++ edit and debug experience.

C++ Code Editing & CMake Support
- Samples Browser: Referencing
is now even easier with Android Studio 2.2. Within the code editor window, find
occurrences of your app code in Google Android sample code to help jump start
your app development. Learn more.

Build
- Instant Run Improvements: Introduced in Android Studio 2.0,
Run is our major, long-term investment to make Android development as fast
and lightweight. Since launch, it has significantly improved the edit, build,
run iteration cycles for many developers. In this release, we have made many
stability and reliability improvements to Instant Run. If you have previously
disabled Instant Run, we encourage you to re-enable it and let us know if you
come across further issues. (Settings ? Build, Execution, Deployment ? Instant
Run [Windows/Linux] , Preferences ? Build, Execution, Deployment ? Instant Run
[OS X]). For details on the fixes that we have made, see the
2.2 release notes.
Enable Instant Run
- APK Analyzer: Easily inspect the contents of your APKs to
understand the size contribution of each component. This feature can be helpful
when debugging
issues. Plus, with the APK Analyzer you can compare two versions of an APK.
more.
APK Analyzer
- Build cache (Experimental): We are continuing our
investments to improve build speeds with the introduction of a new experimental
build cache that will help reduce both full and incremental build times. Just
addandroid.enableBuildCache=trueto your
gradle.properties file.

Test
- Virtual Sensors in the Android Emulator: The Android
Emulator now includes a new set of virtual sensors controls. With the new UI
controls, you can now test
Sensors such as Accelerometer, Ambient Temperature, Magnetometer and more.

- Espresso Test Recorder (Beta): The Espresso Test Recorder
lets you easily create UI tests by recording interactions with your app; it then
outputs the
test code for you. You record your interactions with a device and add
assertions to verify UI elements in particular snapshots of your app. Espresso
Test Recorder then takes the saved recording and automatically generates a
corresponding UI test. You can run the test locally, on your continuous
integration server, or using
Test Lab for Android.
more.
- GPU Debugger (Beta): The GPU Debugger is now in Beta. You
can now capture a stream of OpenGL ES commands on your Android device and then
replay it from inside Android Studio for analysis. You can also fully inspect
the GPU state of any given OpenGL ES command to better understand and debug your
graphical output.
