SDK Build Tools release notes

Android SDK Build-Tools is a component of the Android SDK required for building Android apps. It's installed in the <sdk>/build-tools/ directory.

You should always keep your Build Tools component updated by downloading the latest version using the Android SDK Manager. If you're using Android plugin for Gradle 3.0.0 or higher, your project automatically uses a default version of the build tools that the plugin specifies. To use a different version of the build tools, specify it using buildToolsVersion in your module's build.gradle, as follows:

android {
    buildToolsVersion "27.0.3"


The sections below provide notes about releases of the Build Tools. To determine which revisions of the Build Tools are available in your SDK, refer to the Installed Packages listing in the Android SDK Manager.
