How to increase maximum heap size for the Gradle daemon?

Question

When signin 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 m         


        

Answer 1

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.

Answer 2

You can try any one of the following

1) change the gradle.properties file and change the heap size as per your requirement.

If org.gradle.jvmargs=-Xmx2048M is not sufficient then change to 4096 as given

org.gradle.jvmargs=-Xmx4096M

2)"Edit Custom VM Options" from the Help menu.

It will open studio.vmoptions / studio64.exe.vmoptions file

Change the content to

-Xms128m

-Xmx4096m

-XX:MaxPermSize=1024m

-XX:ReservedCodeCacheSize=200m

-XX:+UseCompressedOops

Save the the file and restart Android Studio.

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.
