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.

of if you already have `gradle.properties` file in `android` folder add this line `org.gradle.jvmargs=-Xmx4096m` — Amjad, Feb 08 '22 at 09:48

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.

I have tried this to no avail. I even created the command line variable GRADLE_USER_HOME=C:\Users\\.gradle. I also tried putting it in my platform/andorid/gradle.properties but it continues to use 2048MB – Mark A. Rupert Jan 07 '19 at 04:30

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.

This is Android question, but it pops up for scala out of memory gradle search anyway, so let me try to save some poor souls hours of searching.

Scala forks the JVM by default when compiling, and org.gradle.jvmargs do not apply to it. Instead, you have to pass the args to the Scala plugin in gradle. It depends on your particular setup on where that might be, for me, this works:

tasks.withType(ScalaCompile) {
    configure(scalaCompileOptions.forkOptions) {
        jvmArgs = ['-Xss4m', '-Xmx2048m']
    }
}

If your build is comprised of multiple subprojects, put this inside the subprojects { } block inside the main build.gradle.

Add following code to your build.gradle file.

 android {
     dexOptions {
     incremental true       
     javaMaxHeapSize "4g"
      }
    }

that is not the same the message is telling to do. Maybe your way is the old way? – NullPointerException Nov 23 '17 at 11:22
also i noticed that i currently have that line added, dexOptions { javaMaxHeapSize "4g" } – NullPointerException Nov 23 '17 at 11:23
so it is not the solution, because with that line i'm getting the message – NullPointerException Nov 23 '17 at 11:23
What message are you getting? – Samir Bhatt Nov 23 '17 at 11:26

@VishvaDave I have added source link. Check that. There are so many question have same code that does not mean that code is copied. Even almost all devloper use this code snippet in all application development for hit size issue. – Samir Bhatt Nov 23 '17 at 11:34
dexOptions { javaMaxHeapSize "2g" } Try this – ND1010_ Nov 23 '17 at 11:34

@SamirBhatt Actually this question is duplicate. you should give possible link in comment. avoid answering this type of duplicate questions. – Vidhi Dave Nov 23 '17 at 11:35
