Gradle: How to increase maximum heap size for the Gradle daemon?

Question

When signing an apk, I got this message:

To run dex in process, the Gradle daemon needs a larger heap. It currently has 1024 MB. For faster builds, increase the maximum heap size for the Gradle daemon to at least 4608 MB (based on the dexOptions.javaMaxHeapSize = 4g). To do this set org.gradle.jvmargs=-Xmx4608M in the project gradle.properties. For more information see https://docs.gradle.org/current/userguide/build_environment.html 

In my project, I don't have a gradle.properties file, but I have a file called gradle-wrapper.properties.

I opened that file and added the line org.gradle.jvmargs=-Xmx4608M.

After that, I tried to sign the apk again but I'm still getting the message of increasing Gradle heap size.

How to achieve that?

If you don't have gradle.properties then go to your project folder you will find gradle files there create a text file and name it as gradle.properties removing .txt and then add the below code to that file.

# Project-wide Gradle settings.  # IDE (e.g. Android Studio) users: # Gradle settings configured through the IDE *will override* # any settings specified in this file.  # For more details on how to configure your build environment visit # http://www.gradle.org/docs/current/userguide/build_environment.html  # Specifies the JVM arguments used for the daemon process. # The setting is particularly useful for tweaking memory settings. org.gradle.jvmargs=-Xmx4096m  # When configured, Gradle will run in incubating parallel mode. # This option should only be used with decoupled projects. More details, visit # http://www.gradle.org/docs/current/userguide/multi_project_builds.html#sec:decoupled_projects # org.gradle.parallel=true 

and save it then open your project in Android Studio and click on sync now.

I hope it will resolve your issue, if not please let me know.

I know you said your project doesnt have gradle.properties but you could create a global one in C:\Users\user\.gradle and add:

 org.gradle.jvmargs=-Xmx4096M 

And remember to run gradle --stop to kill any previous daemons.
