A Healthy Dose of Gradle
summary
Gradle is the Android build system and the talk claims a build can be both fast and tailored by using the wrapper, plugins and explicit inputs/outputs rather than hacks. It demonstrates custom tasks and plugins (a Greeter task and an uppercase file-copy task), how to annotate properties with @InputDirectory/@OutputDirectory and use incremental task inputs, and where to put code in buildSrc. For profiling it uses --profile, the Gradle Build Scan and the open-source Gradle Profiler (six warmups then many measured runs) and shows incremental builds stop unnecessary work.
