Top Build Performance issues in Android projects – 2023 Edition
In this talk, we will discuss some of the top build performance issues that Android developers face, and provide solutions to these problems.
We will begin by explaining what the Gradle build cache is and how it works. We will then outline the common issues that developers encounter when using Gradle build cache.
We will then demonstrate combining the powerful Build Validation Scripts with automation and notifications to systematically surface new build cache misses and to keep them from reappearing once they have been fixed.
We will close by diving into Artifact Transform insights in Build Scan – the most commonly requested feature by Android developers – and by showing how you can use the new Tests API in Gradle Enterprise to automate your flaky test workflows.
Talk Title
Improving Android Developer Experience with Gradle Build Scans
As a developer, you just want your builds to work but every now and then things go wrong and you need to investigate the build. That investigation sucks up a lot of your time and forces context switching. In this talk we show how build scans can help save a lot of time when you need to find build performance bottlenecks, investigate/troubleshoot CI and build/tool chain failures, visualize your dependencies, etc. to troubleshoot/investigate build issues and accelerate your builds/tests.
From this session you will learn…
