Out of memory error: Java heap memory on Android Studio

Question

How do I fix java.lang.OutOfMemoryError: Java heap space when compiling my Android project?

I get this after I upgraded to version 1 of Android Studio.

Answer 1

Just add this to the gradle file:

android{
testOptions {
        ....
        unitTests.all {
            jvmArgs "-Xmx2g" // to avoid outOfMemory exception
        }
        ....
    }
}

Answer 2

None of the answers worked for me but finally I found something that worked in my case:

Automatically managing paging files size

In windows:

1. Under "Advanced System Settings"
2. Advanced Tab
3. Performance section, settings...
4. Advanced Tab
5. Virtual memory... Change...
6. Select Automatically manage paging files size for all drives

I don't remember why I had this unchecked but this was causing trouble in my gradle builds (with flutter).

Answer 3

Here is what I did:

1st step: In your App, go to GRADLE SCRIPTS -> GRADLE.PROPERTIES -> change org.gradle.jvmargs=-Xmxm to org.gradle.jvmargs=-Xmx4G

2nd Step: In your App, go to GRADLE SCRIPTS -> build.gradle -> in the android{

//add this line:

dexOptions {
   javaMaxHeapSize = "4G"
   }
}

Answer 4

Build => Clean Project

then

Build => Rebuild Project

When I do this, it always fixes for me.

Answer 5

I've finally solved it by limiting the Google Play service in gradle dependency.

The problem however was caused by the Google Play service, and by simply change it to a specific library, it is now solved.

 com.google.android.gms:play-services-base:6.5.87

Answer 6

assign more memory to Gradle in the project's gradle.properties file.For example:

org.gradle.jvmargs=-Xmx1024m
