Speeding up Android builds by 'fanning out' tests on Bitrise

This article discusses how to speed up Android builds using Bitrise, a build automation tool. It introduces the concept of "fan out" builds, which allow tests to run in parallel, reducing overall build time. The article covers various techniques to achieve faster builds, including caching Gradle dependencies, using static dependency versions, organizing test cases, and disabling APK splitting. It also provides an example workflow that demonstrates how to trigger fan-out builds for UI testing, runs tests in parallel, and generates a single test report. By applying these techniques, developers can significantly reduce build times and improve overall development efficiency.
