Windows defender might impact performance pycharm

Как исправить ошибку: Windows Defender might be impacting your build performance? PhpStorm

При открытии или создании проекта в PhpStorm (скорее всего и в PyCharm) иногда может возникнуть ошибка: Windows Defender might be impacting your build performance. PhpStorm checked the following directories…

Ее можно решить нажав на пункт Fix во всплывшем окошечке или сделать все манипуляции в ручную.

Если вы решили исправить эту ошибку в ручную, то вам необходимо:

1. Зайти в «Параметры Windows».

2. Далее выбрать «Обновление и безопасность».

3. Далее «Безопасность Windows».

4. Далее «Защита от вирусов и угроз».

5. Под заголовком «Параметры защиты от вирусов и угроз нажмите» на пункт «Управление настройками».

6. Пролистайте вниз до заголовка «Исключения» и нажмите на пункт «Добавление или удаление исключений».

7. Нажмите на кнопку «Добавить исключение», выберите тип «Папка» и добавьте папку со своим проектом и, если вы проделываете это впервые, папку где PhpStorm хранит настройки и кэш (в моем случае C:UsersAlex.PhpStorm2019.3system)

UPD. После обновления Windows 10 до сборки 2004 появилась проблем в том, что даже при добавлении папок в исключения Windows Defender все равно возникает ошибка при каждом открытии проекта.

Пока не нашел как решить эту проблему, как только узнаю, обновлю пост.

Antivirus Impact on Build Speed Follow

Some antivirus software can interfere with the IDE build process, causing builds to run dramatically slower. When you run a build in the IDE, many class files are created on your computer. If your antivirus software has real-time scanning enabled, the antivirus can force the build process to halt each time a file is created while the antivirus scans that file.

If you’re using Windows Defender, the IDE automatically checks whether you have real-time scanning enabled, and whether the scanning is configured to process directories where the IDE writes a lot of files.

The IDE offers you a possibility to exclude those directories from scanning automatically (this feature is available in 2019.2+ IDE versions).

If you prefer to perform the necessary configuration manually, you can do so by following these steps:

• Click the Start button
• Type “Windows Security”
• Click on “Virus and threat protection”
• Click on “Manage settings” under “Virus & threat protection settings”
• Scroll down if needed, and then click on “Add or remove exclusions”
• For every folder shown in the notification, press the + button, select “Folder” from the menu, and select the folder.

If you’re using a different anti-virus product, you still may be impacted by the problem, but there is no possibility to detect or correct this automatically. If you’re experiencing poor build performance, please follow the instructions of your anti-virus product to exclude the following directories from real-time scanning:

• The directory of your project
• The directory used by IntelliJ IDEA to store settings and caches
• The Gradle cache directory ( %USERPROFILE%.gradle )

We also recommend excluding the IDE process from the antivirus to improve the startup performance.

Caution: To ensure that your computer is safe from malicious software, you should not completely disable real-time scanning or your antivirus software.

Windows Defender is significantly impacting performance (due to recent updates as it seems).

We are running application test suites on two Windows 10 machines using a Jenkins configuration which tracks the execution time.

Since last Thursday the execution time on both machines doubled for no apparent reason. Test suite run times jumped from 1,5 hours to 3 hours and from 3,5 to 7 hours. After extensive investigations we disabled Windows Defender and test suite run times dropped to their previous values. We did not yet succeed to achieve that by excluding relevant files, folders, and processes, which would be the preferred approach as the real-time check cannot and shall not be permanently disabled.

Checking the event log on the affected machines showed several Windows Defender related updates around when the test run-times soared up. The updates are referring to KB2267602 and KB4052623. One of the updates installed a kernel mode driver service.

I did not yet succeed to find out why the Windows Defender updates would cause a performance impact like that — i.e. is that known and intentional by MS or is it an issue that has not yet been noticed. At any rate this is a very unsatisfying situation and the performance impact on test execution is inacceptable.

Any information to shed light on this issue would be appreciated.

The issue that you’ve encountered can be due software conflict or possible broken system components. To isolate your concern, we suggest that you perform a clean boot. This troubleshooting technique will help us determine if there are conflicts with other applications that affect the performance of your device. Please click here for the complete steps.

Once you’re in the clean boot state, try to navigate with your computer and check if you’ll still encounter the same level of performance.

Note: After the troubleshooting, refer to this section: “ How to reset the computer to start normally after clean boot troubleshooting ” on the same support article to boot the computer in normal setup once the issue has been resolved.

After you’ve performed a clean boot, you can also run the System File Checker and DISM tool. These are usually used to repair any possible corruptions on the system files. Click this Forum Article for the steps that you can use. Then, see the result with its performance.

We’re just here if you need further help.

How satisfied are you with this reply?

Thanks for your feedback.

I am sorry but this answer seems to be completely off the mark to me. «Software conflict» and «broken systems components» are just generic terms void of any context.

To repeat: The issue occurred on two different machines at about the same time. The only common denominator is the update of the Windows Defender Antimalware Platform which happened at that time on both machines.

According to KB4052623 and to many professional journals this update was quite a massive change entailing -among others- that the Malware Protection Engine was moved to a different system location. The fix was referred to as «emergency security patch» in the news and was related to the scanning of downloaded files which might trigger a vulnerability in the MPE.

So, what our test suite basically does is to remotely throw tons of files at a test application running on the two machines.

In the meantime we succeeded to reduce the test suite run-time by excluding relevant folders, files and processes from being scanned by Windows Defender Antimalware Platform. However, this is not satisfying as firstly the run-time is still higher than in any test runs prior to the issue occurrence and secondly this measure to exclude test suite items from scanning was not required before the issue occurred.

Is there performance comparison data available for this latest version of the Windows Defender Antimalware Platform? Does it do anything different than the previous versions resulting in increased scan time, processing time, start-up time etc.? I would think that this information is a somewhat essential key performance indicator for any antivirus software and therefore needs to be observed by the development teams when issuing a new version.

Unless your telling me that your recommendations regarding clean boot and DISM are distinctively connected to the WDAP issues mentioned I will not walk down that road. I did that for other issues where the same recommendations were made and it always a turned out as a dead end.

PyCharm 2020.2.2

PyCharm 2020.2.2 is out now with important fixes to improve your usability and productivity. Update from within PyCharm (Help | Check for Updates), using the JetBrains Toolbox, or by downloading the new version from our website.

Fixes in this build:

• We fixed an old pain-point in our inspections where a false positive “unexpected arguments” was thrown while using Flask-SQLAlchemy.
• We fixed an issue with Windows Defender that used to raise a message “Windows Defender might impact performance” even when the directories were already listed in the Windows Defender exclusions list.
• If you work with Angular.js you would like to know that a fix to completely ignore syntax errors in ng-options attribute has been implemented.
• We fixed a problem that prompted the GitHub login dialog when users tried to update a project from or push changes to GitHub.

We also had important fixes in our console subsystem:

• We fixed a bug that threw a FutureWarning in the console while using Pandas.
• We fixed a problem that made the console hang after a period of inactivity.

And many more small fixes, see our release notes for more details.

Getting the New Version

You can update PyCharm by choosing Help | Check for Updates (or PyCharm | Check for Updates on macOS) in the IDE. PyCharm will be able to patch itself to the new version, there should no longer be a need to run the full installer.
If you’re on Ubuntu 16.04 or later, or any other Linux distribution that supports snap, you should not need to upgrade manually, you’ll automatically receive the new version.

Windows Defender/Anti-malware Causing Performance Issues after CU update #1932

So, after uninstalling my old Ubuntu Bash lxrun /uninstall /full and after the update lxrun /install I noticed, as promised, that processes running in WSL could be seen in the Windows task manager (yay!); however, there is an issue that consistently causes Windows Defender/Anti-Malware service to consume over 50% of CPU utilization whenever code compilation or builds are happening inside bash. Back last version (before the processes were visible to Windows — or more sandboxed, not sure) this was not an issue at all. So I’m wondering if this is a worthy trade off? I, for one, as a dev, would prefer to maximize build/compile performance even if that means reverting to a more sandboxed environ (or at least the option to do so).

The text was updated successfully, but these errors were encountered:

For what it’s worth, I always add an exclusion for my big source-code build directories to Windows Defender, for exactly this reason. I trust my own code, and the performance hit is too big otherwise.

Adding to @aseering’s comment, this is a problem even with yarn: yarnpkg/yarn#990

Just tried it out @aseering and noticed a pretty big speedup of a rails app load time. Nice!

I added an exclusion for both my networked drive and my lxss folder.

Adding an exclusion does NOT fix the performance problem. Adding an exclusion for VS does NOT fix the performance problem. Adding an exclusion for IIS does NOT fix the performance problem.

The only solution that works for us is to disable REALTIME protection in Windows Defender.

I also want to note that the performance impact is DRAMATIC.

For instance, a rebuild of a VS2017 solution that takes

20seconds to complete with REALTIME protection turned off, takes more than 3 minutes to complete with Windows Defender REALTIME protection enabled.

Another example: a GIT local check-in with one file changed, completes almost instantly with Windows Defender REALTIME protection DISABLED. This same checkin takes more than 2 minutes with Windows Defender REALTIME protextion enabled.

The exclusions DO NOTHING to improve the situation.

@tanseydavid yes exclusions do not seem to have helped at all for the linux side. 🙁

Yeah, it feels like adding exclusions is just a placebo — the performance is still incredibly slow for a lot of stuff related to development. But how do we even raise an issue with the windows defender team about this?

@tanseydavid — The issue that you have described, is that under WSL? Or, just in Windows general outside WSL?

@rdodev & @kumarharsh — In WSL, are you guys seeing any differences when defender realtime protection is turned off for the build directory? If you have any data to quantify, that will be useful.

I would like to get some clarification here before reaching out to the defender team internally.

Also, can you share your Windows build numbers, using the ver command from CMD?

I stopped using WSL due to performance issues, and don’t usually run it now. but even with normal powershell, the performance of, for example yarn install is not anywhere near linux when defender is running. You can see some benchmarks in the yarn issue listed above. I realise I’m not adding much to the WSL part of the discussion, but just wanted to add some details for the defender team’s benefit.

@sunilmut this should be very easy for you folks to replicate and grab as many benchmarks as you want.

1. Install WSL
2. Install git/gnumake, etc.
3. Clone kubernetes/kubernetes (for example, or any large repo)
4. See your CPUs pegged at 100%
5. Profit

Aww, just ran into this, while I was trying the Bash for Windows 10 for the first time. It actually freezes the whole Webpack process and it will never finnish, no matter how long you wait.

Guess the Bash is still unusable for web developers.

Blaaaah this is killing me as projects get bigger. Has nobody at Microsoft looked at all? I’ve seen a ton of closed threads but no action. I have to disable Defender all the time to get Git to finish in reasonable amounts of time (2s for a checkout with it disabled vs over a minute). I’ve tried the workaround — it does nothing.

Same here. I also encounter a lot of disk errors while doing large npm installs. I can see windows defender killing my CPU even though I have a total exclusion on my E drive. It seems like npm may be caching things on an un-excluded directory before unpacking which is triggering windows defender and causing disk issues.

The team is looking into this and will continue investigating. FWIW this rolls up into a broader filesystem perf improvement endeavor.

In the meantime if you can provide us with more specifics so we can generate a repro that would be very helpful. @ow which repo are you using? @justinmchase which errors do you hit?

@tara-raj thanks for the update. Just to toss my own experience out there, I am running 16299 Enterprise and my Windows Defender is locked on due to company policy. As soon as I start WSL I see constant CPU usage from the Defender service hovering around 25%. This goes away the moment I shut down WSL. Inside I am just running tmux and bash, running ssh does not seem to affect it much. Any filesystem actions can take a while especially on /mnt/c. The high CPU usage reduces my computers overall performance and especially the battery life. Adding an exception on the Linux rootfs folder helped, it was 50%+ without it, but it does not solve the issue entirely.

Thanks for looking into this.

Here is a pretty simple repro for the bug I keep seeing:

1. In WSL install node v8.7.0
2. Unzip attached file to /mnt/c/bug , cd into dir
3. npm install

This could be a node/npm bug. I’m not sure yet but I use the same directory linking feature on osx and it doesn’t have this problem. The problem appears to be a combination of being in a linked directory and having the same dependency in both modules. Also i am doing everything under /mnt/e , which I have an exclusion for and ends up being reasonably fast but if I were to copy these files to mv bug

/bug it will trigger windows defender scans which massively slow it down. Also global npm installs or installing a module for the first time which I think is globally caching off of /mnt/e . If I knew where the unmounted files for wsl were located I’d add that to windows defender exclusion. Might be nice if that was done during wsl install by you guys too.

I’m having heavy performance issues related to Windows Defender and WSL as well. For me, it’s when I’m switching tmux panes and opening files in vim. Disabling realtime protection in the Windows Defender Security Center causes a massive (>100x) speedup in performance for these tasks.

I’d really appreciate it if anyone had a workaround besides just disabling realtime protection.

FWIW this rolls up into a broader filesystem perf improvement endeavor.

@tara-raj Would this endeavor be limited to WSL, or would also transcend to Windows’ NTFS filesystem too?

@tara-raj I can get the poor performance to occur on almost any repo.

Do a git clone on something like this — the performance will be slow in general, but can push it further by committing new changes or just installing with npm — in all seriousness I’m turning Defender off 6-8 times a day to get the performance bottleneck out of the way. I’ve not timed it, but I’d hazard a guess it’s more than 4x as bad with Defender enabled.

There’s a ton of documentation about this across repositories — Yarn has a bunch of ongoing threads about this and has been writing workarounds to handle it. Generally speaking, WSL works great, but I will say these performance issues have been crippling and frustrating.

I’m working on migrating from the old version of bash to the windows store version of bash and cannot find the new location of the lxss folder. Anyone know where volfs is being stored these days?

For those here having the same issue, I’ve just completely given up on Defender pinning my CPU all the time. Would prefer to have it on, but currently nigh unusable on my setup.

If you want to force Realtime protection off, you can use this registry key, since Microsoft insists that it will turn itself back on within a few hours on Fall Creator’s and up.

Paste below into a file, add .reg extension, double click. Reboot and boom, hey, it’s actually usable.

The sad part is that this issue was reported over 8 months ago and we’ve yet to see any progress or patch to remedy the issue. Instead of having to disable Windows Defender, they should revert to the way WSL worked before and let it be its own isolated subsystem. Integration with Windows is what caused all these perf problems.

Please bear with us. We are investigating. If it was a simple issue to fix, it’d have been fixed by now 😉

@ow Weird, I tried cloning crafty-vagrant, both within the WSL file system and in /mnt/c and neither seemed to take super long, nor did my CPU go above 15%. I only heard about WSL a week ago and installed it very recently. Have you been using it for long? Maybe you’ve got an older version installed? Or some cruft left over from an old version?

@marcfor I have been using WSL since the day it launched, and have written much about my experience with it so far. Initial repositories appear fine, but once you begin to get complex directories in them — run npm install, composer install, vagrant up on Crafty-vagrant — then start trying to commit on a regular basis and it’s agony. I can reproduce the behavior across three machines, one is just a few weeks old.

I once ran git status in a big repository under /mnt/c from WSL, it’s unresponsive for a minute.
While the same operation using the Windows native git is completed within one second.
I suppose this is also related to Windows Defender.

As an FYI. We use the WSL Switcher to use centos under WSL. Adding exclusions helped improve git performance by 50%.

Adding: @bitcrazed , please feel free to reach out to me. Our team uses WSL extensively, and we’re happy to get you use cases / situations to reproduce.

Cannot reproduce effects of disabling real-time protection or adding exclusion to project folder. Most noticeable is when running yarn start. On MacOs this takes roughly 2-10s, on Ubuntu 16.04 around 2s and on WSL I get between 40-60s which is unbearable. rebuilding takes 200-800ms on Ubuntu, 1-2s on MacOs and 9-20s on WSL. No effect on this by changing Defender/Firewall settings

@firewave Strongly recommend dumping McAfee if there is any possible way. Windows already has a built-in anti virus and, to put it lightly, its more trustworthy.

Suggesting different antivirus software isn’t a solution to the problem. Many companies enforce policies that require specific antivirus or firewall software, which may not be user-configurable.

There definitely seem to be changes in 1903 that allow Defender to get out of the way of other installed real-time antivirus scanners. While that is helpful from a system management viewpoint, it also means that these antivirus scanners may not know what they should or shouldn’t be scanning, so they just scan everything all the time.

I know this is not perfect, but SSD helps a lot if you can’t turn off third party scanners.

@ithiru I’m using SSDs and the performance is still horrible. I see this regularly with Debian 10 using apt, like:

Always very slow, Task Manager shows Antimalware Service Executable busy. The same thing under Hyper-V is faster (and that one is backed by an old spinning disk).

I do not know what you all are talking about with performance issues, I live daily in xfce4 on my w10 workstations — tinyurl.com/donofrioworkremmina2020 and I daily update and it is fine, I mean sure firefox is not working but arora does everything I need within wsl1 and ubuntu 18.04 granted I do mostly ssh/rdp (yes I rdp from ubuntu because I use remmina — it is cross platform) I but I have used many application/projects from aweather to ansible. my update as documented in my raw setup text file in that link:
«sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get dist-upgrade -y && sudo apt-get autoremove -y && sudo apt-get autoclean -y && sudo sync && sudo sync»

@drichardson I am guessing your Debian distro is still running on WSL1.

When you run wsl.exe -l -v at your Windows command-line, what do you see?

As you can see from above, I am currently running Ubuntu on WSL2 and openSUSE on WSL1.

If your Debian is running as Version 1, then you’re running Debian atop WSL1 whereupon you’ll likely bump into the well known WSL1 file IO perf challenges that come from running Linux binaries atop Windows IO stack. If, on the other hand, you run a distro atop WSL2, your distro/binaries will be running in a container directly on a Linux kernel instance in lightweight VM, which doesn’t use Windows’ IO stack and isn’t affected by anti-malware tools like Defender etc.

I’ve always looked at a vm as «a way around the rules» in that I’m guessing like normal vm’s that scom cannot scan the wsl2 vm? Unlike wsl1 that lives within ntfs and is scanned by local antivirus but also scan have it’s file scanned from scom I’m guessing as well? let me know if I’ve got this wrong and I’ll remove this reply.

The Defender team are currently assessing how/what/when/if Defender on the host interacts with workloads running in VMs and/or Defender running IN VMs. I do not yet have anything to share on what the final outcomes will be, but know that we’re working closely with them on this matter.

so I was correct that wsl2 vm’s are loopback filesystems and not normalized (within the same partition/ntfs?) like in wsl1?

so I was correct that wsl2 vm’s are loopback filesystem

Close. WSL2 is Hyper-V VM, and on WSL2 Linux /dev/sda (which does not exist in WSL1) is backed by a Windows VHDX. Presumably (?) Defender leaves activity on the backing file alone; but similar to Rich’s answer, I’ve never really investigated the extent to which Defender peeks reads and writes on that file. But whatever Defender does (if anything) as of this writing, it does it more quietly than the WSL1 hidden filesystem, and the performance is better.

ok I guess I am just trying to see without just grabbing an insider box and trying it, is wsl2 a loopback filesystem sitting on a ntfs partition (akin to vmware workstation does?) if so this is a cheat unlike wsl1 you could scan with scom and whatever tools Microsoft provided now with wsl2 I’m guessing this is why we are now seeing ATP applications all of a sudden?

In WSL2, each distro’s filesystem is stored in individual EXT formatted VHDX files which are mounted within the distro’s container. As such, the distros’ filesystems aren’t stored in NTFS like in WSL1.

It’s nothing to do with cheating. It’s all about compatibility and performance.

As I said, we’re working with Defender and several other teams on a number of initiatives to further improve WSL2’s integration, performance, interop, and manageability. Stay tuned to our blog for updates as we make progress.

What I mean by ‘cheating’ is if your corp says you use windows and you setup a vm just to run your linux the way you want, unimpeded by domain policy’s on the network like airwatch and other MDM clients. wsl1 allowed — perhaps mistakenly in my eye the ability to absorb linux into windows tools and domain policy’s like scom and defender just worked (at least for me in last three years) but for some reason vm’s seem to «get a pass» at least as far as I view it, I’m flexable if you can tell me I’m mistaken or incorrect.

I totally hear you re. management of WSL instances. The fact that WSL1 ran atop NT and thus could be managed and monitored by existing Windows tooling and infrastructure is something many enterprises in particular have expressed considerable appreciation for.

But the reality is that for those using WSL, WSL1’s compatibility and file IO performance just weren’t where they needed to be, so we had to change tack and utilize our new lightweight container infrastructure to deliver high performance and 100% compat.

This does mean, however, that many of the management tools & tech that you’d use to manage, secure, configure, and operate physical Linux boxes and/or VM’s are also likely to work just the same in WSL2!

And as I said above, there are teams actively looking into providing enhanced management, monitoring, and protection of Linux VMs (inc. WSL) and physical boxes, details of which will emerge over time.

If you’d like to enquire/discuss further, do reach out via email to crloewen and richturn at you know where dot com.

Really looking forward to the perf improvements. After running Linux native for years, I switched to windows due to WSL, and love it; I get the Windows OS experience with a Debian development environment — not to mention the VSCode WSL plugin ❤️ . The only problem is performance, and I look forward to improvements. Congratulations on shipping such a wonderful piece of software 🎈

Why use MinGW64? is that for compile or for GUI like xfce4 accelerated? I only ask because I use «daily» full gui using VcXsrv (for last three years) my build guide and photo’s at tinyurl.com/donofrioworkremmina2020 (yes I rdp from ubuntu w/xfce4 within remmina client)

I compile using native gcc, and I use bash, all native, have done this for past three years and all is working great, so long as it doesn’t want to touch non-existing hardware (aka usermode rocks for my needs)

To improve performance, PyCharm can update your Windows Defender configuration

This will require running a command with administrator privileges. 
Alternatively, you can configure Windows Defender manually, according to the instructions.

Your anti-virus program might be impacting your build performance. Android Studio checked the following directories:

Can anyone help me, how to get this disable this setting or increase the performance of android studio? I am using android studio version 3.5.

2 Answers 2

You should exclude this dir from antivirus in your machine.

1. Open Windows Defender Security Center.
2. Select Virus & threat protection > Virus & threat protection settings > Add or remove exclusions.
3. Under Add an exclusion, select folder

Cause

While Android Studio build process is in action, it create a lot of intermediate files in order to compile and package source code and resources. Enabling real time scanning in antivirus softwares will force it to scan all these newly created files for vulnerabilities. This is may interfere with the Android Studio build process, causing builds to run dramatically slower.

Exclude real-time scanning on these directories.

Gradle cache
%USERPROFILE%.gradle

Android Studio projects
%USERPROFILE%AndroidStudioProjects

Android SDK
%USERPROFILE%AppDataLocalAndroidSDK

Android Studio system files
C:Program FilesAndroidAndroid Studiosystem

This is how you can accomplish the same in different antivirus softwares.
Windows Defender
Kaspersky
AVG Antivirus

Note: You can also disable the disable real-time scanning completely. This method isn’t recommenced since it will open security risks.

Antivirus Impact on Android Studio Build Speed

Some antivirus software can interfere with the IDE build process, causing builds to run dramatically slower. When you run a build in the IDE, many class files are created on your computer. If your antivirus software has real-time scanning enabled, the antivirus can force the build process to halt each time a file is created while the antivirus scans that file.

If you’re using Windows Defender, the IDE automatically checks whether you have real-time scanning enabled, and whether the scanning is configured to process directories where the IDE writes a lot of files.

The IDE offers you a possibility to exclude those directories from scanning automatically (this feature is available in 2019.2+ IDE versions).

If you prefer to perform the necessary configuration manually, you can do so by following these steps:

Click the Start button
Type “Windows Security”
Click on “Virus and threat protection”
Click on “Manage settings” under “Virus & threat protection settings”
Scroll down if needed, and then click on “Add or remove exclusions”
For every folder shown in the notification, press the + button, select “Folder” from the menu, and select the folder.
If you’re using a different anti-virus product, you still may be impacted by the problem, but there is no possibility to detect or correct this automatically. If you’re experiencing poor build performance, please follow the instructions of your anti-virus product to exclude the following directories from real-time scanning:

The directory of your project
The directory used by IntelliJ IDEA to store settings and caches
The Gradle cache directory (%USERPROFILE%.gradle)
We also recommend excluding the IDE process from the antivirus to improve startup performance.

Caution: To ensure that your computer is safe from malicious software, you should not completely disable real-time scanning or your antivirus software.

Implement In-app Update In Android

Make sure every user of your app is on the new version.

Apr 6, 2020 · 8 min read

In this article, we will learn about the In-app update feature in Android what is all about In-app update, what are the benefits of using the In-app update in your android application. Recently I’ve been working on a product in which I need to Implement an In-app update Why we need to Implement this?.

As a Developer we always want our users to have the updated version of their application but there are a lot of people who actually turned off their auto update from google play store and he/she doesn’t know about any update available or not.

To overcome the problem Google Introduced this feature called In-app update from this feature you can easily prompt the user to update the application and with the user permission you can update the application also while updating the app user can be able to interact with the application. Now the user doesn’t need to go to google play store to check there is any update available or not.

What is In-App Update:

An In-app update was Introduced as a part of the Play Core Library, which actually allows you to prompts the user to update the application when there is any update available on the Google Play Store.

There are two modes of an In-app update.

• Flexible Update
• Immediate Update

Flexible Update:

In Flexible update, the dialog will appear and after the update, the user can interact with the application.

This mode is recommended to use when there is no major change In your application like some features that don’t affect the core functionality of your application.

The update of the application is downloading in the background in the flexible update and after the completion of the downloading, the user will see the dialog in which the user needs to restart the application. The dialog will not automatically show, we need to check and show to the user and we will learn how later.

Benefits:

The major benefit of the flexible update is the user can interact with the application.

Windows Defender might be impacting your build performance

After I updated my PyCharm IDE to 19.2.0 from the 19.1.2. I am getting the following warning:

Do you think that it is secure, necessary and really improve the performance?

You need to exclude those directories in your Windows Security’s Exclusion list.

1. Type Windows Security in your windows Search bar
2. Click Virus & threat protection
3. Under Virus & threat protection settings header, click Manage Settings
4. Under Exclusions header, click Add or remove exclusions
5. Click Add an exclusion
6. Select type Folder
7. Enter the directory
8. You are done

Yes it is secure, necessary and really improves the performance as the real-time scanning is enabled in Windows defender by default. Read this: Minimize the impact of antivirus software on build speed.

I faced the same problem with Android Studio which is from same company after the recent update. So what you can do is you will get the directory which is causing this error. Like

Then you need to go to Windows Defender and add these folders to the exclusion in Windows Defender or the antivirus you are using.

I did the above steps with adding exceptions to the defender, but the message in the WebStorm application did not want to disappear.

Running the WebStorm application as administrator helped me.

Optimize Android Studio performance on Windows

Android Studio performance on Windows can be impacted by a variety of factors. This section describes how you can optimize Android Studio settings to get the best possible performance on Windows.

Minimize the impact of antivirus software on build speed

Some antivirus software can interfere with the Android Studio build process, causing builds to run dramatically slower. When you run a build in Android Studio, Gradle compiles your app’s resources and source code and then packages the compiled resources together in an APK. During this process, many files are created on your computer. If your antivirus software has real-time scanning enabled, the antivirus can force the build process to halt each time a file is created while the antivirus scans that file.

To avoid this issue, you can exclude certain directories from real-time scanning in your antivirus software.
