This repo is a fork of the Google Santa Tracker app for Android. This fork was created to demonstrate some of the tips and tricks on how to speed up your Android Gradle builds.
- Use latest Android Gradle plugin
- Avoid legacy multidex
- Disable multi-APK
- Include minimal resources
- Disable png crunching
- Use Instant Run
- Avoid inadvertent changes
- Don’t use dynamic versions
- Watch the memory
- Enable Gradle caching
More details coming...
Check out this repo and switch to the agp-2.2.0 branch. This branch contains the pre-optimized build configurations. See Getting the first build working section.
Best way to observe the build performance in this branch is to use the [Gradle profiler] (https://github.com/gradle/gradle-profiler). You should familiarize yourself with the Gradle profiler before proceeding. Their repo contains excellent documentation.
Once you have observed the build performance of this branch in various scenarios (see performance.scenarios), you can switch to agp-3.0.0 branch to observe the optimized build performance by running the same set of build scenarios in performance.scenarios file. You can search throughout the project for "Tip" to find the build config tip to achieve the build time improvements.
First up, Santa Tracker is powered by Firebase, so you'll need to enable it on your Google account over at the Firebase console. Once you're in the console, follow these steps:
- Create a new project
- Add Firebase to your Android app
- Package name:
com.google.android.apps.santatracker.debug - Debug signing certificate can be blank, or follow the instructions in the tooltip to find yours.
- Save the
google-services.jsonfile to thesanta-tracker/directory
Now you should be able to plug your phone in (or fire up an emulator) and run:
./gradlew santa-tracker:installDebug
Alternatively, import the source code into Android Studio (File, Import Project).
Note: You'll need Android SDK version 24, build tools 24.0.0, and the Android Support Library to compile the project. If you're unsure about this, use Android Studio and tick the appropriate boxes in the SDK Manager.
