How To Make Android Gradle Build Faster

If you’re tired of waiting for ages for your Android project to build just for testing a simple change, you’re not alone. Gradle can feel slow—especially as your app grows. The pain of wasting time building project the nightmare only android developers know! So, I will tell you A few smart tweaks that can make your builds faster.

In this post, we’ll go through a quick tips to boost your Gradle performance.

1- Open gradle.properties in your project

2- Add the following Configs:

– Heap Size

Markdown

org.gradle.jvmargs=-Xmx6144m -Dfile.encoding=UTF-8

org.gradle.jvmargs=-Xmx6144m -Dfile.encoding=UTF-8

This allocates a maximum heap size of 6144 megabytes (6 GB) to the Gradle Daemon. Increasing the heap size can improve build performance for large projects by providing more memory for Gradle to operate. You can make it lower or more if needed.

– Gradle Daemon

Markdown

org.gradle.daemon=true

org.gradle.daemon=true

The Daemon is a long-lived background process that keeps build information in memory. Using the Daemon significantly speeds up subsequent builds.

– parallel execution

Markdown

org.gradle.parallel=true
org.gradle.workers.max=8

org.gradle.parallel=true
org.gradle.workers.max=8

This enables parallel execution of tasks within a project. If your project has multiple modules, Gradle can execute tasks in these modules concurrently utilizing 8 parallel workers.

– BUILD CACHING

Markdown

org.gradle.caching=true
org.gradle.configuration-cache=true

org.gradle.caching=true
org.gradle.configuration-cache=true

This feature speeds up builds by caching the tasks & result of the configuration phase. The configuration phase is where Gradle builds the task graph for your project.

# Custom Gradle Configs by Amrk000

# Project-wide Gradle settings for Android
# Gradle settings configured through the IDE *will override*
# For more details: http://www.gradle.org/docs/current/userguide/build_environment.html

# Defaults:
# AndroidX package structure to make it clearer which packages are bundled: https://developer.android.com/topic/libraries/support-library/androidx-rn
android.useAndroidX=true

# Enables namespacing of each library's R class so that its R class includes only the
# resources declared in the library itself and none from the library's dependencies,
# thereby reducing the size of the R class for that library
android.nonTransitiveRClass=true

You can make these configs default globally for all projects by creating gradle.properties containing the needed configs in C:\Users\USERNAME\.gradle directory.
