Build Tools is a component of the Android SDK required for building Android
application code. The latest version of these tools is included in the
SDK starter package and 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. By default, the Android SDK uses the most recent downloaded version of the Build Tools. If your projects depend on older versions of the Build Tools, the SDK Manager allows you to download and maintain separate versions of the tools for use with those projects.
To use a specific version of the Build Tools in your application project:
- In the root folder of your application project, find the
project.properties
file. - Open the file and specify the Build Tools version by adding a
buildtools
property on a separate line:sdk.buildtools=17.0.0
- In the root folder of your application project, find the
build.gradle
file. - Open the file and specify the Build Tools version by adding a
buildToolsVersion
property to theandroid
section:android { ... buildToolsVersion "17.0.0" ... }
