New

• All new Layout Editor with tools custom-built to support ConstraintLayout.
• New Layout Inspector lets you examine snapshots of your layout hierarchy while your app is running on the emulator or a device.
• New Assistant window to help you integrate Firebase services into your app.
• New APK Analyzer tool so you can inspect the contents of your packaged app.
• New Espresso Test Recorder tool (currently in beta) to help you create UI tests by recording your own interactions.
• New build cache (currently experimental) to speed up build performance.
• New C/C++ build integration with CMake and ndk-build. Compile and build new or existing native code into libraries packaged into your APK, and debug using lldb. For new projects, Android Studio uses CMake by default, but also supports ndk-build for existing projects. To learn how to include native code in your Android application, read Add C and C++ Code to Your Project. To learn how to debug native code with lldb, see Debug Native Code.
• New Samples Browser so you can easily look up Google Android sample code from within Android Studio to jump start app development.
• New Merged Manifest Viewer to help you diagnose how your manifest file merges with your app dependencies across project build variants.
• The Run window now contains log messages for the current running app. Note that you can configure thelogcat Monitor display, but not the Run window.
• New Android Emulator features:
  • Added new Virtual Sensors and Cellular > Signal Strength controls.
  • Added an LTE option to the Cellular > Network type control.
  • Added simulated vertical swipes for scrolling through vertical menus with a mouse wheel.
• New Run/Debug Configuration features:
  • The Debugger tab of the Android App and Android Tests templates now contain several new options for debugging with LLDB.
  • The Profiling tab of the Android App and Android Tests templates now contain a Capture GPU Commands option for enabling GPU tracing. You can display GPU traces in the GPU Debugger (a beta feature).
  • The Android Tests template now has a Firebase Test Lab Device Matrix option for the Deployment Target.
  • The Native Application template has been deprecated. If you use this template in a project, Android Studio automatically converts it to the Android App template.
  • The Android Application template has been renamed to Android App.
• Improved installation, configuration, performance, and UI features in the GPU Debugger (currently in beta).
• Android Studio now comes bundled with OpenJDK 8. Existing projects still use the JDK specified in File > Project Structure > SDK Location. You can switch to use the new bundled JDK by clicking File > Project Structure > SDK Location and checking the Use embedded JDK checkbox.
• Added new help menus and buttons in the UI so you can more easily find the online documentation.
