We are experimenting with using an internal artifactory server where we can host our Android project’s modules. Avoid building the project’s modules every time Now, a new Gradle JVM is spawned only once because we have chained successive gradle tasks in a single invocation. gradlew check print-dependency-tree assembleIntegrationtest assembleAndroidTest test assembleJenkins -PpreDe圎nable=falseīuild-ci: build-without-predex test-integration-remote Initially, writing the Makefile with a non-gradle mindset lead us to separating the tasks in a generic way. This step gave us a pretty decent speed-up shaving almost 5 minutes off our build time. Finally, a new Android apk bundle is ready for rolloutįine-tuning the build performance step-by-step: Don’t spawn multiple new gradle JVMs ĭon’t spawn multiple gradle JVMs during the make process for different gradle targets.This includes tasks such as Proguard shrinking, zipAligning, minification, etc Assemble Release - a production/beta ready assembly flavour.Assemble Remote - some flavour of assemble that can run on a remote testing platform (we use Google’s gcloud). Assemble Tests - some flavour of assemble that will help us run the tests.Jenkins polls for changes and starts building the commit.This is a standard practice for local gradle dev environments that everyone should follow We sped this up by using a Gradle daemon process.It takes a significant amount of time to build the sub-modules, wait for the apk to compile, etc.Build an apk locally to test things on the Android emulator/test devices.Here is what our Android build pipeline looks like: We use Gradle, which is a standard build tool for Android projects. We’ve still got a long way to go until we get to a build time we’re happy with, but we’ve made some good steps in the right direction. The quick build time helps us stay focused and sharp. Going from a 20 minute build to a 11 minute build time on our CI servers makes a dramatic difference in day-to-day work on our android app. Naturally, speed is a critical component, allowing faster iterations and quick feedback. We build our software with a focus on Continuous Integration and quick deployment lifecycles.
