Android Studio 3: making gradle build a bit faster

Enable offline mode

If you are on a slow network connection, your build times may suffer when Gradle attempts to use network resources to resolve dependencies. You can tell Gradle to avoid using network resources by using only the artifacts that it has cached locally.

To use Gradle offline when building with Android Studio, proceed as follows:

1. Open the Preferences window by clicking File > Settings (on Mac, Android Studio > Preferences).
2. In the left pane, click Build, Execution, Deployment > Gradle.
3. Check the Offline work checkbox.
4. Click Apply or OK.

Enable configuration on demand

For Gradle to know exactly how to build your app, the build system configures all modules in your project, and their dependencies, before every build (even if you are building and testing only a single module). This slows down the build process for large multi-module projects. To tell Gradle to configure only the modules that you want to build, enable configuration on demand by following these steps:

1. Open the Preferences window by clicking File > Settings (on Mac, Android Studio > Preferences).
2. In the left pane, click Build, Execution, Deployment > Compiler.
3. Check the Configure on demand checkbox.
4. Click Apply or OK
