Why don't you use a more general solution, for example, detekt? It shows problems right in the IDE without build, has its own rules, can generate reports and can be added in Gradle build.

[@Zefanya-Teki]

What are the downsides of using detekt straight in the IDE? We use it at work, but we only run it manually (usually before comitting)

[@amrel-madah5277]

@@Zefanya-Teki U can use pre-commit or pre-pish as a githook to run that check automatically before every commit or push

[@Zefanya-Teki]

@@amrel-madah5277 Thanks :)

[@kotl4931]

detekt has a wrapper for ktlint , it also allow to auto-correct if enabled .the advantage of using the wrapper is that you can see all the formatting rules in config.yaml instead of jumping to the reports files

[@tonnie7079]

Reminds me of Police who maintain order, KtLint would be ideal to stop my code running berserk. Thanks for sharing.

[@dotneko9059]

Oh yes. Ktlint is awesome. Great video as always, Phillip

[@leosvxy]

Great tutorial Philipp ! , but there are somethings that are different now, could you do an updated video please? , that would be awesome, Thanks in advanced!

[@maximooze3196]

Next SonarQube @Philipp 👍🏻, thank you for another good content.

[@lakshminarayanacharan837]

Wonderful stuff philipp Love from India

[@minds_clear_02.23_]

Perfect! It's really simple! Philipp, thank you!!!

[@BapeRuLLZ]

How we did it when I worked with a team is that we agreed upon a code formatting style we all liked and then one of us configured it in android studio in the code auto-formatting options and then he shared the config file with the rest of the team and we imported it. Then you turn on auto formatting on save, or just get used to using ctrl+alt+L and there you go.

[@aviksutar]

best!! falling in love with every tutorials of yours

[@smart1hashi]

Beautiful Explanation. Do you have playlist for beginners but not soon beginners to learn from Just saw your channel first time today and subscribed straight after this video

[@Adam0001]

On time 😊, Thanks Philipp 💐

[@amirhosseinghafoorian9985]

so useful video, I will definitely use it in my project

[@vitalijuskolinko9011]

Thank you, my master :) Nice plugin, but it works a little bit buggy - sometimes it doesn't show changes in COMMIT section after I run ./gradlew-ktlintFormat. Need to restart Android Studio :)

[@Another0neTime]

All your video are belong to us. But seriously, great video.

[@dharamveergupta1305]

It was a great guide, Can you make one set-up guide for SonarQube for SonarLint.

[@taar1]

Is this an official tool from JetBrains or Google or private third party?

[@moumnalmunawy1806]

Why people use sealed class for navigation instead of enum?

[@rhen4610]

He already made his statement about that on another video

[@purplehazer417]

enum on steroids

[@UpLiftingU007]

How you will pase any paramter with enums?

[@fernando_s97]

because of parameters

[@moumnalmunawy1806]

@@UpLiftingU007 you can via the constructor

[@alexandervlasik7178]

Philipp, thank you very much. I really enjoy your videos. Do not stop, please. And why did you stop to make android news videos?

[@PhilippLackner]

Thanks! In the past months there weren't any major changes worth to make a whole video about I felt like. I'll make them when something cool changes :)

[@easybusinessou]

Thanks

[@masti437]

Hi Philip ... I am a subscriber of your paid courses ... The content you add are amazing and valuable and I love it. I want to request a content ............... We use git with android studio right via terminal and via UI interface .... can you show all the stuff that you can do with the UI in android studio git functions(Not via terminal) .... there are no source materials on this on internet .... Thank you

[@AhmedBenFadhel]

Thank you for this video. I want to know what to do to make ktlint run on a specific buildType (for example debug BuildType) and having as a result only one report "KtlintDebugSourceSetCheck" ?

[@marlonlom]

Ktlint is great! how to use it across all modules for the gradle project?

[@e4basil]

nicely explained

[@safionweb]

Great content 👑

[@Daaaaaaavid]

"Task with path 'ktlintFormat' not found in project"?

[@stanleykou5643]

Awesome!

[@ewomer100]

Is there a way to get this to work if you refactor change the name of the source directory 'java' to 'kotlin' ? As it is now the formatting only works if the sub folder's name is java

[@mustafaammar551]

very cool vedeo you are the best

[@abdulraafay5226]

Hi, could you make a video on how to cache images that were retrieved from a network request.

[@simonwambua3710]

Whats the difference in usage between ktlint and spotless?

[@CHIchangching]

Philipp, can you please share how to set ktlint for specific folder or path only? I tried with in Android block sourceSets { main { java.srcDirs = ['src/main/java'] res.srcDirs = ['src/main/res'] manifest.srcFile 'src/main/AndroidManifest.xml' } } but when i ran ktlint, it still by default runs for AndroidTests, and Test folder. Any ideas?

[@purplehazer417]

thanks, just thought about that :)

[@Leon-un2ii]

Could you also make a tutorial on how to make an app lock screen with a password or pin, please?

[@tonnie7079]

Any idea on how to do it using Kotlin DSL

[@pr0adam]

sometimes android studio wont even know the lazy list syntax if you dont do the wildcard import lols

[@mandroidx1474]

How about sonarLint?

[@medium010]

./gradlew: Permission denied

[@Theloftyt]

works gj

[@ArunKumar-vu5bd]

When you prebuild ktlint error every time, doesn't it increase the build time?

[@sachinmalik9574]

yes it does, other alternative is to run it precommit

[@PhilippLackner]

Yep that works too 👍

[@renzcarlosalanga1970]

detekt is better in static code analysis

[@sheikhs4896]

In an Android developer i also want to work in Germany..

[@sergioqcostas]

I love your videos but hate every lint out there, lol.

[@wiiznokes2237]

There is a shortcut for doing that automaticaly i think

[@PhilippLackner]

And who wants to go into every file manually and apply that shortcut? 😂

[@flavouredflight8628]

ah yes! ctrl+alt+l

[@wiiznokes2237]

@@flavouredflight8628 Yes! And you can select a directory, otherwise CTRL + SHIFT + ALT + L

[@simpleuxapps8759]

@@wiiznokes2237 That shortcut handles only formatting issues. It dosen't addresses other lint issues, such as unused imports.

[@salvadorjohndeniel]

@@simpleuxapps8759 It also removes unused imports
