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

Had this <code>Xms</code> and <code>Xmx</code> 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.

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.

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.

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.

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

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

<a href="http://tools.android.com/tech-docs/configuration" rel="nofollow">http://tools.android.com/tech-docs/configuration</a> 

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 (<code>studio.exe.vmoptions</code> in my case) over and modify it, the change is respected.

However, the fun doesn't stop there. There's an upper value for <code>-Xmx</code> 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 <code>-Xmx</code> to <code>2048m</code>, but I found that if I set it to anything larger than <code>1500m,</code> 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.

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.

There are a lot of answers that are now outdated.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

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

Windows:
<code>%USERPROFILE%\.{FOLDER_NAME}\studio64.exe.vmoptions</code>

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

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

The contents of the newly created <code>*.vmoptions</code> file should be:

<pre><code>-Xms128m
-Xmx750m
-XX:MaxPermSize=350m
-XX:ReservedCodeCacheSize=96m
-XX:+UseCompressedOops
</code></pre>

To increase the RAM allotment change <code>-XmX750m</code> to another value.

IF by changing or creating the <code>.studio.exe.vmoptions</code> doesn't work, then try changing the <code>gradle.properties</code> file and change the heap size as per your requirement.

It really worked for me on my Windows 7 with 4Gb RAM and Android Studio 2.2 install on it.

Working properly with no error and displaying 'Gradle Sync complete'

I've been using Android Studio for 3 months now and one of the apps I started on it has become fairly large. The memory usage indicated at the bottom right of the program says my allocated heap is maxed at 494M.

When I start to change the XML files my memory usage quickly reaches that cap and the IDE crashes with an Out Of Memory error like this.

I've tried to increase the heap size using this but so far there has been no effect.

I've looked at dozens of articles and other questions on how to increase the heap size but none of their answers are working. No matter what I do to the VMOPTIONS or the IDE settings the heap size never increases. I believe I am editting the correct file for the VMOPTIONS because if I purposely give it an invalid command Android Studio complains about it and doesn't start. 

I'm using windows 7 - 64 bit and have 16GB RAM.
Has anyone else had this problem with Android Studio? And were you able to fix it?

我已经使用Android Studio 3个月了，我在它上面启动的一个应用程序变得相当大。程序右下角的内存使用量显示，我分配的堆的最大内存为494M。​​当我开始更改XML文件时，我的内存使用量很快就会达到这个上限，IDE就会崩溃，并显示一个内存不足错误，如下所示。​​我试着用这个来增加堆的大小，但是到目前为止还没有效...
