我最近从Eclipse升级到Android Studio,但我并不喜欢这种体验。我比较的是Windows 7 64位终极版,16GB内存,英特尔i7 4770运行NVidia Geforce 780,如果重要的话,我运行的是最新的JDK和最新的Android Studio。
Android Studio在构建项目时非常缓慢,我可以接受,但它也非常消耗资源,有时会使PC速度变慢。
每当我在AS中构建或运行任何东西时,我的PC似乎变得极其缓慢。如果我点击“Gradle build running”旋转器,它也会导致屏幕闪烁,偶尔会让我的第二个显示器空白,我觉得这很奇怪。内存的使用也飙升到3GB,我发现什么都不做就过度了(这是在几次构建后空闲的时候)。
此外,AS底部的面板一直在跳来跳去,这是一种糟糕的用户体验(从Android移动到消息到版本控制或其他任何临时的基础上,这取决于正在发生的事情,这是非常非常恼人的)。
我想知道的基本上是:
1)如何让Android Studio运行得更好?我可能做错了什么,或者错过了一些我不知道的更新,我相信其他人也注意到了这些行为,并找到了一些解决方案。
2)我如何“钉”底部面板,使他们不跳,而是让我,用户,导航到他们当我希望而不是自动切换他们?
非常感谢,如果这不是这些问题的正确位置,我再次道歉。

我使用的是今天最新的稳定版本。这个版本是Android Studio 1.2.2 build # AI-141.1980579,于2015年6月3日发布
这种行为发生在使用Java 7或Java 8时。它似乎与Java版本无关。
我没有使用演示模式。只是普通的观点。
对构建配置进行更改(感谢@Blackbelt和他的回答)似乎对构建有所帮助,但迟缓和一般用户体验等其他问题仍然存在。
总结一下
1)在AndroidStudio的设置> compile启用名为compile独立模块并行的复选框。
2)在帮助>编辑自定义虚拟机选项我有:
-Xms1024m
-Xmx4096m # <------ increase this to most of your RAM
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=440m
-XX:+UseCompressedOops
-XX:-HeapDumpOnOutOfMemoryError
-Dfile.encoding=UTF-8
附注:有些人说注意,而不是虚拟机选项,它是更好的组合可以通过组合成一行命令在gradle覆盖这些行。属性,像这样:
org.gradle。jvmargs=-Xms1024m -Xmx4096m…
3)我有一个老的双核4GB内存,运行ubuntu。Qs命令行选项我只有——offline(它指定构建应该在不访问网络资源的情况下运行)。我还启用了其余的复选框,现在它运行正常:
自动制作项目
使用进程内构建按需配置
检查AndroidStudio的设置,在compile下的复选框“并行编译独立模块”已启用。
在Vmoptions下,我有
-Xmx2048m -XX:MaxPermSize=1024
我有一个老的双核4GB内存,运行ubuntu。Qs命令行选项我只有——offline,它指定构建应该在不访问网络资源的情况下运行。我还启用了其余的复选框:

Edit
可以通过工作室提供额外的选项。vmoptions位于(只需将X.X替换为version):
Windows:转到%USERPROFILE%\. androidstudix . x \studio.exe。Vmoptions(或studio64.exe.vmoptions)
麦克:~ /图书馆/ / .AndroidStudioX.X / studio.vmoptions偏好
Linux: ~ / .AndroidStudioX.X /工作室。Vmoptions(和/或studio64.vmoptions)
增加-Xmx的值应该会有很大帮助。如
-Xms1024m
-Xmx4096m
-XX:MaxPermSize=1024m
-XX:ReservedCodeCacheSize=256m
-XX:+UseCompressedOops
将分配4G作为最大堆,初始值为1G
编辑:
在windows上,默认值存储在C:\Program Files\Android\Android Studio\bin\*.vmoptions中。IDE允许您通过Help->编辑自定义虚拟机选项来调整这些值(感谢@Code-Read指出这一点)。

Android studio 3.5更容易更改这些值。请访问:
Preferences > Appearance & Behavior > System Settings > Memory Settings
我的Android Studio不仅在一般使用时很慢,在构建时也很慢。
以下是我所做的:
卸载Android Studio(不要删除,卸载它,并检查删除SDK)。然后删除位于C:\Users\\文件夹中的Android文件夹,即:. Android, AndroidStudioX。X
通过SDK管理器卸载SDK,删除所有内容(如果有剩余的SDK文件夹,删除它们)
下载并重新安装Android Studio的最新版本(在撰写本文时为v2.1.2);只安装你需要的SDK/模拟器;
现在快了。
在此之前我的故事:
My laptop sports an Intel Core i7-3612QM and 8gig of ram. When I builded, all the 4 cores/8 threads were on 100% usage. My entire system froze until the ~10 minute wass done. Gradle took me like ~10 unproductive minutes of slow down. This is very annoying. I am using Android Studio since 1.4. There were also tremendous slow down when I copy paste code to and from, selecting menus, right-click context menus, editing manifest, editing gradle files, opening layout files, rendering in the UI Editor, etc. Its was very unusable most of the time.
Due to frustration, I did the above steps. Its fast now. Very usable just as before. I build for only ~20 seconds compare to ~10minutes before that. Also, Android Studio eats about 6gig with emulator and browser with lots of tab open, unlike before its hovering on 98% RAM usage. Not just that, I even saved 45 gigs of space for whatever reason. I only use couple of SDKs and Emulators when I checked the Android SDK folder, it occupies 45gig of space! I think the IDE is having a hard time accessing/IO on my SDK folder.
如果你已经尝试了其他给出的解决方案,仍然遇到同样的问题,可能是时候完全删除Android IDE/ sdk并重新开始了(可能需要一段时间来重新设置,但这是值得的。考虑到我已经被这种懒惰折磨了好几个月了,还让我失去了工作效率)。
我真的认为这可能是由于从那时起所做的累积补丁造成的。或者是我那碎片整理得很差的驱动器上的45g SDK文件夹。我不知道,也许我错了。
谢谢你!HTH
在您学习的过程中,诊断As的性能问题并非易事!在我的例子中,一个9215字符长的字符串数组(见下文)导致AS在我每次输入几个字符时转储线程。线程转储反过来导致AS一次冻结数秒。此错误出现在Windows 64位的AS 2.2版本中,在2.2.1中仍然出现,但在2.1中没有出现。
发现长字符串导致了我的锁定涉及了大量的试验和错误。但是,在这个过程中我学到了很多,比如:
idea.log contains excellent diagnostics (Help->Show Log in Explorer);
If you see extreme, but intermittent slowdowns, suspect AS is dumping threads. This will be reported in idea.log. If threads are being dumped, the dumps will tell what code AS was executing when the problem occurred;
Find out whether the problem occurs in other projects. If not:
Look for unusual content in the project file you are editing when it happens (atypical indentation, long lines, overall size, special characters, etc.);
Try exporting settings from another project (File->Export Settings) and importing them to the problem project (File->Import Settings);
If so:
If threads were dumped, consult these and text in idea.log near in time to the dump notices for details;
Consult idea.log for messages about memory consumption and see other answers to this question such as https://stackoverflow.com/a/30818099/5025060 for advice regarding memory and other tunables.
顺便说一句,目前我已经通过将我的长字符串移动到一个单独的文件(一个只包含数组本身的新类)来解决上面描述的问题。我尽量不使用AS编辑这个文件:
package com.code_read.numerous;
// Stored in this separate file as workaround for but in Android Studio 2.2 and 2.2.1:
public class numstrings {
// Array of long random numbers, pregenerated to save CPU:

建议:
必须说:如果你有任何机会,花一些钱买更好的PC(cpu),
这是最重要的…
调整:
Some people say, that OS (Operating System) might cause much slowness. For example, XP or LINUX (or etc) was mentioned to perform 70% faster (don't know why..).
Disable VCS by File > Settings > Plugins and disable the following things :
CVS Integration; Git Integration; GitHub; Google Cloud ... things; Subversion Integration; hg4idea;
Editor is a resource eating too (especially on Large Monitors) and slow. Make it much much faster: click Help > Edit custom VM options and add these lines :
-Dsun.java2d.d3d=false
-Dsun.java2d.opengl=true
save it and Restart Android Studio.
If Android Studio has a proxy server setting and can't reach the server then it takes a long time to build and waiting for a timeout. Removing it helps much. File > Settings > Appearance & Behavior > System settings > HTTP Proxy.
Another Useful quote (from article):
Modules are expensive… On my current project I had to build some libraries from scratch and had to fork some that almost fitted my needs but not quite! If that modules are not constantly modified, it’s important to have this into consideration: the time needed to compile them from scratch, or even to check if the previous individual module build is up-to-date, can be up to almost 4x greater than to simply load that dependency as a binary .jar/.aar.
Hint: run the gradle build -profile for an HTML report showing where
the time goes regarding the build process.
Note: keep that “unnecessary” modules in your version control system
for the eventuallity of a quickfix/improvement in that dependency.
In your Gradle build script, use only
specific Google Service, like: compile 'com.google.android.gms:play-services-maps:...'
Instead of full Google Library: compile 'com.google.android.gms:play-services:...'
(Compile time goes from 2 minutes to around 25 seconds).
Gradle configures every project before executing tasks, regardless of whether the project is actually needed for the particular build. In global gradle.properties adding this will help much: org.gradle.configureondemand=true
Surprisingly, some people say , they solved problem by reducing: 1) heapsizes to -Xmx256m (instead of higher values); 2) Emulator Ram-size (from Edit AVD > Advanced Settings);
每天的建议:
不要同时运行多个项目。
使用一次后不要关闭模拟器(每次都使用相同的模拟器运行应用程序;如果你测试大型应用,最好使用真正的手机而不是模拟器)。
每次在模拟器中运行你的应用程序后都清理你的项目-点击构建>清洁项目(或重建),你可以使用键盘快捷键。
杀毒软件导致了慢速
In one particular system I looked at, this issue was caused by an over-zealous anti-virus that was interfering with Gradle, the build manager for Android Studio. It seems every time Gradle was "touching" a .jar file, the virus checker was unzipping the .jar and scanning it for viruses first. The Gradle build could only continue once the unzipping and scan was complete, thus leading to very long build times (5 min plus). Since Android Studio, by default, runs a Gradle build when you start up, it manifests as an extremely slow start-up.
这个问题非常容易检查:
当您遇到Android Studio运行缓慢的症状时,请按Ctrl- Alt-Delete并打开Windows任务管理器。
单击Processes选项卡查看活动进程并按CPU排序。如果你看到杀毒软件间歇地占用大量CPU,而Android Studio似乎正在加载,这很可能是同样的问题。
您可以通过查看反病毒软件的扫描日志来进一步验证,检查.jar文件。
要解决这个问题,您必须将正确的目录添加到防病毒软件的“排除文件夹”中。假设你的Windows用户名是“username”,并且你已经在C: drive上安装了Android Studio。然后,您将请求从病毒检查中排除以下目录:
C:\Users\Username\.android
C:\Users\Username\.AndroidStudio2.2
C:\Users\Username\.gradle
C:\Users\Username\.m2
C:\Users\Username\AppData\Local\Android\Sdk
请注意,如果你排除这些目录,你可能需要采取额外的安全预防措施,你应该在工作场所与你的安全部门合作。这可能涉及到在必要时设置自己的Maven存储库。
(我知道这是一个晚的答案,但之前的答案都没有解决这个潜在的问题)
这个答案涉及到在你已经把Xmx和Xms内存设置弄清楚之后,Windows 10的Gradle构建速度变慢的问题。
视窗防护
就Windows Defender而言,仅仅通过“文件”或“文件夹”将文件夹/文件添加到Windows Defender排除列表是不够的。
你必须添加属于Android Studio / Gradle / Java(嵌入式JDK或Oracle JDK)的目录作为“进程”排除到Windows Defender:
看一下大卫·罗森的答案
在Gradle构建过程中…监视Windows任务管理器的进程
在Windows Defender中,为包含文件/可执行文件的目录添加“进程”排除,你看到在与Android Studio / Gradle相关的构建过程中使用CPU
这显然会带来安全隐患。
以下描述了有关在Windows Defender中使用“进程”排除(而不是添加简单的“文件”或“文件夹”排除)的更多细节:
A file name with full path causes the particular binary file to be excluded, i.e. any files it touches, regardless of where the file is located, will not be scanned by Windows Defender. A file name without any path causes any binary file with this file name to be excluded regardless of its location. A path followed by a "*" (e.g. c:\my\private\tools*) causes any binaries under this path to be excluded. Any files touched by these processes will be excluded. This is different from a path exclusion, where files touched by any process under the excluded path is excluded.
这里的关键字是....将这些排除作为“进程”类型的排除考虑到“二进制接触的文件”,而不是手动查找并排除由Android Studio / Gradle生成的每个文件/文件夹。
Windows文件索引
Windows文件索引似乎也会降低Gradle构建的速度。关闭Gradle / Android Studio使用的目录的Windows文件索引。
以下是我排除的“Windows文件索引”和“Windows防御程序”:
C:\Program Files\Android\*
C:\Users\<yourUserAcct>\.android\*
C:\Users\<yourUserAcct>\.AndroidStudio3.0\*
C:\Users\<yourUserAcct>\.gradle\*
C:<pathToYourAndroidStudioProjectFolder>
我尝试在相同的硬件上测试Android Studio 3.1.4的速度:Macbook Pro 2011, RAM 4Gb, SSD 240GB三星,Core i5 2.4Ghz。我在这台机器上安装了3个不同的操作系统:Windows 10, MacOS high Sierra 10.13, Ubuntu 18.04。MacOS/Ubuntu上的平均构建时间(运行命令:gradlew clean build, gradlew clean assemblerrelease)比Windows快30%左右。
On my another working machine: Core i5 3.0 Ghz 7400, RAM 16Gb, SSD 250Gb. Build time takes 4.34min on Windows 10 machine. The same project on a little bit slower processor, but with the same RAM and SSD and it is running Ubuntu 16.04 build time takes two times faster!! Well I was shocked with results, but still I choose Windows as development machine, because it's much more comfortable for me to use comfortable and usable keyboard and sotfware than on Unix like systems. And even if I had to choose between MacOS and Ubuntu - mac is really much easier to setup everything, and Ubuntu is too complex to use for usual people. Choise is up to you.
