New features and installation of Android studio 3.0

Android studio is the official ide of Android. It is designed for Android, which can speed up your development and help you build the best applications for each Android device. It provides tools tailored for Android developers, including rich code editing, debugging, testing and performance analysis tools.

1、 What's new in Android studio 3.0

(1) . core ide changes we upgraded the basic ide from IntelliJ 2016.2 to 2017.1.2, and added many new functions in 2016.3 and 2017.1, including parameter prompt, semantic highlighting, instant results in search, etc.

Many new lint checks.

The immediate run debugging problem 234401 should be solved now. If the program pauses at a breakpoint, the application restarts. However, if the application does not pause at the breakpoint, it can only be restarted when the method implementation changes, and hot plug should work.

(2) . kotlin language Android studio 3.0 includes support for kotlin language. Kotlin can be integrated into the project by converting java files to kotlin (click code > Convert java files to kotlin files), or by creating a new kotlin enabled project using the new project wizard.

New XML font preview, font selection tool and support for downloadable fonts.

(9) New templates for. Android Android studio 3.0 includes a new set of templates in the new project and new module wizards, so you can start developing IOT devices using Android things.

(12) . Google's Maven repository Android support library Maven dependencies can now be used outside the Android SDK manager in the new Maven repository. Combined with the command-line SDK manager tool and gradle, this new distribution method simplifies Maven dependency management using a continuous integration system. To use the new Maven repository, add the URL to build.gradle in the repository block of the file, as follows:

Repository {maven {URL“ https://maven.google.com ” } }

(13) Improvements to the. APK analyzer show fields other than previously available packages, classes, and methods

Show and hide new filtering options for fields and methods at the top

In the tree view, the nodes shown in italics are references that are not defined in the DEX file

For apks with Proguard build enabled, you can load Proguard mapping files that add functionality to the DEX viewer

(14) . new Android plug-ins for gradle when using the new plug-ins for these projects, you should experience the following: faster configuration time due to delayed dependent resolution.

Variation aware dependency solutions apply only to the projects and variations you are building.

Faster incremental build times when simple changes are applied to code or resources.

Migration to new plug-in description address: https://developer.android.google.cn/studio/build/gradle-plugin-3-0-0-migration.html

(15) . use cmake 3.7 or later

(16) . the last two new features of the new Android simulator can be viewed directly on the official website at: https://developer.android.google.cn/studio/preview/features/index.html#cmake

2、 Android studio 3.0 installation

It is recommended to use Google browser before downloading, because many descriptions in the download address are in English, which can be translated into simplified Chinese with one click.
