Android Studio got very slow and constantly "updating indices"
提问by daneejela
There are more similar question on the SO, but I haven't found my answer on any of them so I am opening new one.
SO上还有更多类似的问题，但我还没有找到任何答案，所以我正在打开新的问题。
I am using:
我在用：
Android Studio 2.2.3 (but was same with the 2.2.2) Gradle 2.14.1 JRE 1.8.0
Android Studio 2.2.3（但与 2.2.2 相同）Gradle 2.14.1 JRE 1.8.0
I am using it on the mac, OS X El Capitan (2.5 GHz, i5, 8GB RAM).
我在 Mac OS X El Capitan（2.5 GHz、i5、8GB RAM）上使用它。
It has been working great until few weeks ago, and now it is so painfully slow. Most of the time it is "indexing/updating indices".
直到几周前它一直运行良好，现在它非常缓慢。大多数时候它是“索引/更新索引”。
I am not that concerned about build time (it takes about 30-40sec, but I can live with that) as much as that constant indexing that makes coding almost impossible (overall responsiveness is pretty poor).
我不太关心构建时间（大约需要 30 到 40 秒，但我可以忍受）以及使编码几乎不可能的常量索引（整体响应能力非常差）。
Is there anything in my gradle files that could cause this?
我的 gradle 文件中是否有任何可能导致这种情况的内容？
I do have some dependencies, but the app itself is relatively simple.
我确实有一些依赖项，但应用程序本身相对简单。

}
allprojects {

}
task clean(type: Delete) {

P.S. I have enabled - offline work, parallel and daemon. I have increased VM heap size. I have uploaded to latest Android Studio. I have replaces maven with jcenter(). Is there anything I am missing?
PS 我已启用 - 离线工作、并行和守护进程。我增加了 VM 堆大小。我已上传到最新的 Android Studio。我用 jcenter() 替换了 maven。有什么我想念的吗？

For the others having the same problem:
对于其他有同样问题的人：
My android studio returned back to its original performance (which was ok). It is hard to me to say what made an improvement because I have done lots of changes at once, here are few I recall:
我的 android studio 恢复了原来的性能（没关系）。我很难说是什么改进了，因为我一次做了很多改变，以下是我记得的几个：
- replaced maven with -> jcenter()
- set flag in properties to use default gradle wrapper
- updated android studio to latest version (at the moment 2.2.3)
- enabled gradle daemon - Configuration On Demand
- invalidate cache and restart(few times)
- 用 -> jcenter() 替换 maven
- 在属性中设置标志以使用默认的 gradle 包装器
- 将 android studio 更新到最新版本（目前为 2.2.3）
- 启用 gradle 守护进程 - 按需配置
- 使缓存无效并重新启动（几次）
some of it I have tried before asking this question, but I think all came back to normal when I did last update to Android studio 2.2.3
其中一些我在问这个问题之前已经尝试过，但我认为当我最后一次更新到 Android studio 2.2.3 时，一切都恢复了正常

I've had the same problem, but only when having multiple 'packages' under 'app/java/com.example.projectname'If you have multiple packages within your java folder, try this. It worked instantly for me.
我遇到了同样的问题，但只有在“app/java/com.example.projectname”下有多个“包”时， 如果你的 java 文件夹中有多个包，试试这个。它立即对我有用。
In Android Studio's 'Project Window,' right click on 'app/java/com.example.android.projectname'then click 'Show in Explorer.' Move all of your '.java' files out of their sub-folder and place them all in the 'app/java/com.example.android.projectname' folder.
在 Android Studio 的“项目窗口”中，右键单击“app/java/com.example.android.projectname”，然后单击“在资源管理器中显示”。将所有“.java”文件移出其子文件夹，并将它们全部放在“app/java/com.example.android.projectname”文件夹中。
Next, go back into Android Studio and open up all of your '.java' files. At the top of your code you should see package com.example.android.projectname.subfolder;Because you've removed the 'packages' and relocated the '.java' files, you need to change every '.java' file's package to read package com.example.android.projectname;
接下来，返回 Android Studio 并打开所有“.java”文件。在您的代码顶部，您应该看到package com.example.android.projectname.subfolder;因为您已经删除了“包”并重新定位了“.java”文件，因此您需要更改每个“.java”文件的包以读取package com.example.android.projectname;
You'll also need to go into the manifest and change 'activity android:name=...'
您还需要进入清单并更改“activity android:name=...”
Hopefully that works.
希望这有效。

I got rid of constant "updating indices" issues by increasing the max heap size of Android Studio process.
我通过增加 Android Studio 进程的最大堆大小摆脱了不断的“更新索引”问题。
To do so, change Studio's JVM options(Help -> Edit Custom VM Options...) to include -Xmx2gwhere 2gis the amount of memory enough to keep Studio happy with your project complexity.
要做到这一点，改变Studio的JVM选项（帮助- >编辑自定义虚拟机选项...），包括-Xmx2g其中2g的内存足够让工作室快乐着你的项目的复杂量。

I just deleted the .idea folder and restarted Android Studio then I pressed button "Sync Project with Gradle Files"
我刚刚删除了 .idea 文件夹并重新启动了 Android Studio，然后我按下了“将项目与 Gradle 文件同步”按钮
and everything goes fine.
一切顺利。

Also, you can try:
另外，您可以尝试：
Files -> Invalidate Caches / Restart...
文件 -> 使缓存无效/重新启动...
This worked for me.
这对我有用。
回答by Sanjay Kushwah
Just go to File -> Invalidate Caches / Restart
只需转到 File -> Invalidate Caches / Restart
Then on the dialog that opens select "Invalidate and Restart"
然后在打开的对话框中选择“无效并重新启动”
That's it.
就是这样。
