Android Studio 3.1 Aims to Improve App Development Productivity

Bookmarks

The latest release of Android Studio, version 3.1, focuses on improving app development productivity and includes a new C++ performance profiler, command line support for Kotlin lint checks, SQL code completion and improved refactoring, and more.

The following is a list of major highlights from the release notes:

  • The underlying IntelliJ platform has been upgraded to version 2017.3.3, which improves support for Java 8, auto-migration from JUnit 4 to JUnit 5, and more.

  • Android Studio 3.1 improves Kotlin support, introduced in Android Studio 3.0, by including Kotlin 1.2.30. Additionally, running gradlew lint from the command line now also analyze Kotlin classes.

  • SQL editing has been much improved when using the Room library, including support for code completion within an @Query statement, syntax highlighting, and better integration between the SQL model definition and the Java or Kotlin code referencing it.

  • Android Studio 3.1 uses a new DEX compiler, called D8, to transform .class bytecode into bytecode for the Android Runtime. D8 ensures faster conversion, lower memory usage, and improved code generation.

  • C++ developers also benefit from the latest Android Studio release. Large projects should build significantly faster, while the LLDB debugger provides easier to read output for more C++ data structures. Additionally, the CPU profiler now supports sampling native C++ code.

  • The Network Profiler now includes a Thread View to display network activity for each CPU thread that your app has spawn.

  • The Android Emulator in Android Studio 3.1 is now able to resume a session in under six seconds using QuickBoot, which snapshots emulator sessions. Additionally, it includes images for Android 8.0 (API level 26), Android 8.1 (API level 27), and Android P Developer Preview.

Android Studio 3.1 can be downloaded from the official Android Studio download page, or installed directly from within Android Studio 3.0.
