如何增加分配的堆大小-AndroidStudio-HowtoincreaseAllocatedHeapSize

104  

Open file located at /Applications/Android\ Studio.app/Contents/bin/studio.vmoptions Change the content to

打开位于/Applications/Android\ Studio.app/ content /bin/studio的文件。vmoptions将内容更改为。

-Xms128m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=200m
-XX:+UseCompressedOops

Xmx specifies the maximum memory allocation pool for a Java Virtual Machine (JVM), while Xms specifies the initial memory allocation pool. Your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory.

Xmx指定Java虚拟机(JVM)的最大内存分配池，而Xms指定初始内存分配池。您的JVM将使用Xms数量的内存启动，并且能够使用最大的Xmx数量的内存。

Save the studio.vmoptions file and restart Android Studio.

保存工作室。vmoptions文件，重启Android Studio。

Or, you can go to your android-studio\bin folder and change these -Xmx and -Xms values in studio.exe.vmoptions or studio64.exe.vmoptions files (depending on which version you are running).

或者，您可以访问android-studio\bin文件夹，并在studio.exe中更改这些-Xmx和-Xms值。vmoptions或studio64.exe。vmoptions文件(取决于您正在运行的版本)。

I looked at my Environment Variables and had a System Variable called _JAVA_OPTIONS with the value -Xms256m -Xmx512m, after changing this to -Xms256m -Xmx1024m the max heap size increased accordingly.

我查看了我的环境变量，并有一个名为_JAVA_OPTIONS的系统变量，其值为-Xms256m -Xmx512m，将其更改为-Xms256m -Xmx1024m后，最大堆大小随之增加。

You should not edit any files in the IDE installation directory. Instead, you can customize the attributes by creating your own .properties or .vmoptions files in the following directories. (This has been possible on some platforms before, but it required you to copy and change the entire contents of the files. With the latest changes these properties are now additive instead such that you can set just the attributes you care about, and the rest will use the defaults from the IDE installation).

您不应该在IDE安装目录中编辑任何文件。相反，您可以通过在以下目录中创建自己的.properties或.vmoptions文件来定制属性。(这在以前的一些平台上是可能的，但是它要求您复制和更改文件的全部内容。对于最新的更改，这些属性现在是可添加的，这样您就可以只设置您关心的属性，其余属性将使用IDE安装的默认值)。

Note: As of Android Studio 2.0, you can create/edit this file by accessing the "Edit Custom VM Options" file from the Help menu.

注意:在Android Studio 2.0中，您可以通过访问帮助菜单中的“编辑自定义VM选项”文件来创建/编辑该文件。

I increased my memory following the next Google documentation:

在接下来的谷歌文档中，我增加了内存:

http://tools.android.com/tech-docs/configuration

http://tools.android.com/tech-docs/configuration

By default Android Studio is assigned a max of 750Mb, I changed to 2048Mb.

默认情况下，Android Studio的最大内存为750Mb，我将其修改为2048Mb。

I tried what google described but for me the only thing that it worked was to use an environment variable. I will describe what I did:

我尝试了谷歌所描述的，但是对我来说，它唯一起作用的是使用环境变量。我将描述我所做的:

First I created a directory that I called .AndroidStudioSettings,

首先，我创建了一个名为。androidstudiosettings的目录，

• mkdir .AndroidStudioSettings
• mkdir .AndroidStudioSettings

Then I created a file called studio.vmoptions , and I put in that file the following content:

然后我创建了一个名为studio的文件。vmoptions，我在那个文件里放了以下内容:

-Xms256m 
-Xmx2048m 
-XX:MaxPermSize=512m 
-XX:ReservedCodeCacheSize=128m 
-XX:+UseCompressedOops 

Then I added the STUDIO_VM_OPTIONS environment variables in my .profile file:

然后，我在.profile文件中添加了STUDIO_VM_OPTIONS环境变量:

• export STUDIO_VM_OPTIOnS=/Users/youruser/.AndroidStudioSettings/studio.vmoptions
• 出口STUDIO_VM_OPTIOnS= /用户/对于/ .AndroidStudioSettings / studio.vmoptions

Then I reload my .profile:

然后重新加载。profile:

• source ~/.profile
• 源~ / . profile

And finally I open Android Studio:

最后我打开Android Studio:

• open /Applications/Android\ Studio.app
• 打开/应用程序/ Android \ Studio.app

And now as you can see using the status bar , I have more than 2000 MB available for Android Studio:

现在你可以看到使用状态栏，我有超过2000 MB的Android Studio可用:

You can customize your values according to your need in my case 2048Mb is enough.

您可以根据您的需要定制您的值，在我的情况下，2048Mb就足够了。

UPDATE : Android Studio 2.0 let's you modify this file by accessing "Edit Custom VM Options" from the Help menu, just copy and paste the variables you might want to keep in order to increase it for everversion you might have on your box.

更新:Android Studio 2.0让我们通过从帮助菜单中访问“编辑自定义VM选项”来修改这个文件，只需复制并粘贴您可能想要保存的变量，以便在您的方框中增加everversion。

Note: I now this is not the answer for the post, but maybe this will be helpful for some one that is looking.

注意:我现在这不是这个帖子的答案，但是这可能对正在寻找的人有帮助。

If Nothing of this works for you, try on a Mac this to see if helps you, in the last version of Android Studio, the studio.vmoptions is inside the AndroidStudio.app in your Applications folder.

如果这些都不适合你的话，试试这款Mac电脑，看看它对你是否有帮助。vmoptions在AndroidStudio中。应用程序在您的应用程序文件夹。

So right click or ctrl click on your AndroidStudio.App and then select show package content the studio.vmoptions is in:

右键单击或按ctrl单击AndroidStudio。应用，然后选择显示包内容的工作室。vmoptions是在:

Contents/bin/studio.vmoptions

/ bin / studio.vmoptions内容

Replace or change it and you will get all the RAM you need.

替换或更改它，您将获得所需的所有RAM。

There are a lot of answers that are now outdated. The desired way of changing the heap size for Android Studio recently changed.

现在有很多答案已经过时了。最近，改变Android Studio堆大小的方法发生了变化。

Users should now create their own vmoptions file in one of the following directories;

用户现在应该在以下目录中创建自己的vmoptions文件;

Windows: %USERPROFILE%\.{FOLDER_NAME}\studio64.exe.vmoptions

Windows:% USERPROFILE % \ { FOLDER_NAME } \ studio64.exe.vmoptions

Mac: ~/Library/Preferences/{FOLDER_NAME}/studio.vmoptions

麦克:~ /图书馆/ / { FOLDER_NAME } / studio.vmoptions偏好

Linux: ~/.{FOLDER_NAME}/studio.vmoptions and/or ~/.{FOLDER_NAME}/studio64.vmoptions

Linux:~ /。{ FOLDER_NAME } /工作室。vmoptions和/或~ / { FOLDER_NAME } / studio64.vmoptions

The contents of the newly created *.vmoptions file should be:

新创建的*的内容。vmoptions文件应该是:

-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops

To increase the RAM allotment change -XmX750m to another value.

为了增加RAM分配更改-XmX750m到另一个值。

I tried the _JAVA_OPTIONS thing but it wasn't working for me still.

我尝试了_JAVA_OPTIONS，但它仍然不适合我。

In the end, what worked for me was the following:

最后，对我起作用的是:

• Launching studio64.exe instead of the studio.exe(I've got a 64-bits machine).
• 启动studio64。exe而不是studio。exe(我有一台64位机器)。
• Add/Change the following values in "studio64.exe.vmoptions":
• 在“studio64.exe.vmoptions”中添加/更改以下值:

-Xms2048m
-Xmx2048m
-XX:MaxPermSize=1024m
-XX:+CMSClassUnloadingEnabled

First check how much memory allocated for your android studio to check that follow this steps :

首先检查为android studio分配了多少内存，按照以下步骤进行检查:

File -> Settings->Appearance & Behavior->Appearance

文件->设置->外观和行为->外观

then check the show memory indicator option like below image red highlighted part

然后检查显示内存指示器选项，如下图红色突出显示部分

In my case my RAM is 12Gb so i have allocated memory for android studio 6gb .To edit that follow this steps

在我的情况下，我的RAM是12Gb，所以我为android studio 6gb分配了内存

Help->Edit custom VM options

帮助- >编辑自定义VM选项

-Xmx6g

In my case, i have set it 6gb because my pc ram is 12 GB. Its upto you how much memory you want to allocate to your android studio

在我的例子中，我将它设置为6gb，因为我的pc ram是12gb。你想要分配多少内存给你的android工作室

On Windows 7, the configuration files at [INSTALL-LOCATION]\bin seem to be ignored. Per the following Google documentation, the file to be modified should be here: %USERPROFILE%\.AndroidStudio\studio[64].exe.vmoptions

在Windows 7上，[INSTALL-LOCATION]\bin的配置文件似乎被忽略了。根据下面的谷歌文档，要修改的文件应该在这里:%USERPROFILE%\.AndroidStudio\studio[64].exe.vmoptions

http://tools.android.com/tech-docs/configuration

http://tools.android.com/tech-docs/configuration

Odd that there is no such file upon a clean install of Android Studio 1.1 from the developer site. And they are in the old (ignored) location. Once I copy the file (studio.exe.vmoptions in my case) over and modify it, the change is respected.

奇怪的是，在开发人员站点上安装了Android Studio 1.1之后，却没有这样的文件。它们在旧的(被忽略的)位置。一旦我复制文件(studio.exe)。在我的例子中是vmoptions)对它进行修改和修改之后，修改就会得到尊重。

However, the fun doesn't stop there. There's an upper value for -Xmx which may be related to the amount of memory in your system. I just bumped my machine's memory from 4Gb to 16Gb, and assumed I could set -Xmx to 2048m, but I found that if I set it to anything larger than 1500m, Android Studio would silently fail to launch with no indication at all as to why. I have more RAM on the way, so it will be interesting to see if I can increase the value at that point.

然而，乐趣并不仅限于此。有一个-Xmx的上限值，它可能与系统中的内存数量有关。我刚刚把我的机器内存从4Gb调到16Gb，并假设我可以将-Xmx调到2048m，但是我发现如果我把它调到任何大于1500m的内存，Android Studio会无声地失败，根本不知道为什么会这样。我在路上有更多的内存，所以看我能不能增加那个点的值是很有趣的。

I hope this additional information is helpful. While all of the above replies were undoubtedly true at one point (and may still be in some environments), I found that this was the only approach that increased the memory used by AS for me.

我希望这些额外的信息能有所帮助。虽然以上所有的回答在某一时刻无疑都是正确的(并且可能仍然在某些环境中)，但我发现这是唯一增加AS用于我的内存的方法。

I found on on Windows 7/8 (64-bit), as of Android Studio 1.1.0:

我在Windows 7/8(64位)上发现，Android Studio 1.1.0版:

[INSTALL_DIR]\bin\studio64.exe.vmoptions be used (if it exists), otherwise it would always fall back to %USERPROFILE%.\AndroidStudio\studio[64].exe.vmoptions

[INSTALL_DIR]\ bin \ studio64.exe。可以使用vmoptions(如果存在的话)，否则总是会回到%USERPROFILE%.\AndroidStudio\studio[64].exe.vmoptions

If you want the settings managed from %USERPROFILE%.\AndroidStudio\studio[64].exe.vmoptions, just delete the one in the installation directory.

如果您想要从%USERPROFILE%管理设置。\AndroidStudio\studio[64].exe。vmoptions，只删除安装目录中的一个。

Go in the Gradle Scripts -> local.properties and paste this

进入等级脚本->本地。属性和粘贴这个

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

, if you want to change it to 512. Hope it works !

如果你想把它改成512。希望它能够工作!

Had this Xms and Xmx memory low issue happen to me any time I was working with the XML. I also tried increasing this memory, only to find that it just took a little longer for it to happen again.

如果我在处理XML时遇到了Xms和Xmx内存不足的问题。我也尝试增加这种记忆，结果发现它只是花了更长的时间才再次发生。

After getting very frustrated and almost deciding to convert all my current projects back over to Eclipse, which I did not want to do, I figured out what was causing it and was able to repeat this failure and prevent it every time.

在感到非常沮丧并几乎决定将所有当前的项目转换回Eclipse(这是我不想做的)之后，我找到了导致它的原因，并能够每次重复此失败并防止它。

While editing the XML in (Text view), and using the "Preview" render view, this causes the loss of memory, every time. Turning off "Preview" and using the Design tab to render the screen only, I am able to use Android Studio all day long, with no crash.

在(文本视图)中编辑XML并使用“预览”呈现视图时，每次都会导致内存丢失。关闭“预览”并使用Design选项卡只显示屏幕，我可以整天使用Android Studio，不会崩溃。

I wish this could be fixed for good, because it would be very nice to use the "Preview" render while editing the XML, however I am glad I can keep using Android Studio.

我希望这个问题能得到永久的解决，因为在编辑XML时使用“预览”呈现会很好，但是我很高兴我可以继续使用Android Studio。
