Android Studio 构建 gradle OutOfMemoryError

问题描述

我是 Android 新手.我在 Android Studio 中导入 Github 项目，但我看到这个问题 `Error:java.lang.OutOfMemoryError: Java heap space

错误:java.lang.OutOfMemoryError:Java 堆空间.请在项目的 gradle.properties 文件中为 Gradle 分配更多内存.例如，gradle.properties 文件中的以下行将最大 Java 堆大小设置为 1,024 MB:org.gradle.jvmargs=-Xmx1024m

方法三:

转到安装它的 Android Studio 文件夹.有文件stduio.exe和studio64.exe，文件类型为VMOPTIONS，用记事本打开它，你会看到类似这样的东西:>

-Xms512m-Xmx1280m-XX:MaxPermSize=350m-XX:ReservedCodeCacheSize=225m-XX:+UseConcMarkSweepGC-XX:SoftRefLRUPolicyMSPerMB=50-ea-Djna.nosys=true-Djna.boot.library.path=-Djna.debug_load=true-Djna.debug_load.jna=true-Dsun.io.useCanonCaches=false-Djava.net.preferIPv4Stack=true-Didea.paths.selector=AndroidStudio1.3-Didea.platform.prefix=AndroidStudio

然后更改两个值以适应您的记忆，如下所示

-Xms512m-Xmx1280m

I'm new in Android. I import Github project in Android studio, but i see this problem `Error:java.lang.OutOfMemoryError: Java heap space

I can't fix this problem with this .how should i do to fix that?

解决方案

One of the methods below should work for you:

Open gradle.properties file from your project treeadd this line at the memory allocation line

org.gradle.jvmargs=-XX\:MaxHeapSize\=256m -Xmx256m

or

org.gradle.jvmargs=-XX\:MaxHeapSize\=512m -Xmx512m

or

org.gradle.jvmargs=-XX\:MaxHeapSize\=1024m -Xmx1024m

Depending on the Memory of your computer. Then

To clean up your gradle cache and implement your new heap size memory changes

Step 1 : Start Android studio and close any open project (File > Close Project).

Step 2 : On Welcome window, Go to Configure > Settings.

Step 3 : Go to Build, Execution, Deployment > Compiler

Step 4 : Change Build process heap size (Mbytes) to 512 and Additional build process to VM Options to -Xmx512m. Or any memory allocation in correspondent to your PC

Step 5 : Revalidate/Restart Android Studio.

Go to your Android Studio Folder Where it is installed. There is File stduio.exe and studio64.exe with file type of VMOPTIONS, open it in notepad you will see Something like this:

-Xms512m
-Xmx1280m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=225m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Djna.nosys=true
-Djna.boot.library.path=

-Djna.debug_load=true
-Djna.debug_load.jna=true
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Didea.paths.selector=AndroidStudio1.3
-Didea.platform.prefix=AndroidStudio

Then change two values to suite you memory as below

-Xms512m
-Xmx1280m
