Love the way you teach one thing at time with detail. we want to see more advance and small suject like how to use android studio profil tool to detect memory leak, how to use some android studio plugins, everything about gradle, materiel design
Thank you very much, Philipp! I finally found out the problem why my login function didn't work. It was because of that obfuscation 🤣 Thanks for clearing that up!
Thanks for the recap PL. In addition, the older version of Play Console had an option to upload the mapping.txt file along with the release build which de-obfuscates any crashes/ANR reported. I haven't used the new console yet, but I hope it will still be there somewhere.
I really like the way you explain things just keeping them simple and straight. Can you please do a video regarding the Android App bundle which is used for updating the application in the playstore ?.
Hi I just started watching your channel , new to android development so i am watching your android fundamental series and it's awesome and updated, I really feel connection and the flow so plz let me know, what do u recommend next ? better be a playlist or topics thanks...
I really like your presentation/explanation style and your explanation is very very well. BTW, how many hours do you research for creating a new video?
Regarding "data class ..." would one need to not obfuscate every method & reference variable (such as LiveData variables) that makes use of the dataclasses or just not obfuscate the dataclasses themselves?
As you mentioned, we should avoid obfuscation for DTO classes cause of the serialization. How if we use @SerializedName("...") for any fields? I think we don't have to exclude them anymore.
If you follow this up with deployment that would be awesome. Phillipp do any of your app playlists deploy to play? Would love to see a complete app playlist on Continuous integration or Continuous deployment setup that has automated test suite
@@PhilippLackner I know it's not for everyone, since many people will not be doing this on at scale or with a large team of people. However I would bet a good amount of people would benefit from them. I also like robotics and automation in the physical world so finding a way to automate the build release process is cool, even cooler if you automate the test suite as well as the deployment because it takes out the possibility for human error. I think you will enjoy learning about it Phillipp, even if it doesn't end up on the channel, I think you will have good time with it. Thanks again for all the great videos! You have seriously changed the game for many people!
This is absolutely helpful..... could you please make tutorial on "Play Feature Delivery" which I am making 3D resources based app development. And I am beginner for app development in android studio.There are four types in it like Install time delivery, on-demand delivery, conditional delivery and instant delivery. First two are useful 🙏
Nice content well done man. Could you please talk about ci/cd such as fastlane and how to integrate it with github actions and google play .thanks in advance🌹🌹
I have tried this option on my project. But unfortunately, it is won't be working very well. For an example of my login activity, R8 has renamed all my XML id into another name that could not pass data through to the form validate and API request.
what about the inner static classes (Like u said as Model class of josn ) which are inside the class which we have added pro Guard rule for not obfuscate this calss .* does this means variable name which are in inner class also not obfuscated?
Sir,, Please help me.. I have faced a problem.. My app previous update version was only 10 megabyte. But now I have added some features,, the size jumped to 25 MB, which is not possible because I have added very small amount of code... When I cancled all and go to previous version by github using version control; it also showing 25MB in released version,,, which was 10MB..
"This App Bundle contains native code, and you've not uploaded debug symbols. We recommend that you upload a symbol file to make your crashes and ANRs easier to analyse and debug." whats this error?.. where I will get that file ?
man i swear i start my project by watching ur video and now i end it with this tutorial R8 & ProGuard
Best channel for learning Android Dev. Thanks !
This man really makes complex things simple , also wondering that would you make a tutorial about gradle ?
Thanks a lot! Not planned atm, but maybe in future
Love the way you teach one thing at time with detail. we want to see more advance and small suject like how to use android studio profil tool to detect memory leak, how to use some android studio plugins, everything about gradle, materiel design
Though these concepts are familiar to me it gives me a quick recap for my interview preparation.
Thanks Pl.
Glad it was helpful!
Thank you very much, Philipp!
I finally found out the problem why my login function didn't work. It was because of that obfuscation 🤣
Thanks for clearing that up!
Glad it helped!
Best hair in all of Android tutorials
i've successfully obfuscate my code because of your video thank you
Very nice, Very nice.
I love the Lackner one stop Android shop for professionals at RUclips
I knew it. But it's the perfect Video to understand all of the Proguard & Obfuscating for beginners.
Great work bro, Keep it up!👍
Philipp Lackner you are amazing. you make everything simple
Best teacher 💪
Thanks!
i learned a lot from you and keeping learning from you. thanks for sharing your knowledge with us.

Your "data classes" example saved my time. It was exactly what I was looking for. Thank you.
Really informative video. Thanks ❤
Glad it was helpful!
Very well explained. I was having exactly this problem with JSON.
Bro u are the best youtuber for app developing and error fixing. Best 💯👍thanks bro and can you tell me something in which I contact you.
Thanks for the recap PL. In addition, the older version of Play Console had an option to upload the mapping.txt file along with the release build which de-obfuscates any crashes/ANR reported. I haven't used the new console yet, but I hope it will still be there somewhere.
thanks boss .. you changed my life
Thank you, I was looking for this these days!!! :D
A brilliant way to deliver a complex topic. Hats off to you man 🙂
Thanks for the video. Could you make a series of how to release your app?
Thanks alot man, you made my work easier. I logged my email just to like and comment👍
AMAZING much needed video bud!

Excellent tutorial, thanks!
Excellent video, thank you very much, I hope and there is second part of the video
Thanks and welcome
useful thanks so much!
Why to backup the mapping file? If Google Play automatically translate the obfuscated code as the Android App Bundle contains the mapping file.
Thank you very much Bro
Very cool video
wish you all the best ❤❤❤👍👍👍👍
thanks wish you the same!
Wooow, perfect guy! thank you so much!
You're welcome!
Damn you are best !

Very helpful video
Absolutely brillant.👍👍
If possible ,Can you make video on dsl kotlin
Amazing.
Thanks

I'd watch the coroutine playlist afterwards and then it's up to you. Whatever is interesting for you
@@PhilippLackner Thanks Phil It's Really Helping ❤️✌️
Gracias, me sirvió mucho, excelente explicación....
Great topic

Arigato 😊

make a video to use in spring boot application for jars
Thank you!

That's correct, It will work.

still learning about CI/CD myself

Does all the comments inside your classes would be obfuscated too?
No there is no reason to include comments in a release build anyways, so they will just be removed
@@PhilippLackner alright, noted on this. Thank you.
very good, as always. Do you have something about signing apps and playstore upload?
Nice content well done man. Could you please talk about ci/cd such as fastlane and how to integrate it with github actions and google play .thanks in advance🌹🌹
Hi ) could you show more examples with R8 and ProGuard, like some small, real project?)))
Philipp I think your forgot to explain "-dontwarn".
my app working perfectly on many devices, after "minifyEnabled true" even the mainactivity cant open
I have tried this option on my project. But unfortunately, it is won't be working very well. For an example of my login activity, R8 has renamed all my XML id into another name that could not pass data through to the form validate and API request.
Hi Philipp! Thanks for the knowledge! I have a question: Is there any way to find out which classes the R8 compiler is breaking?
I haven't fill proguard rule and uploaded my app to the market with minify = true. But haven't face any crashes🤔
Excellent! Do you know any rules to keep the classes dynamically generated by ViewBinding?
Which plugin you have used in your android studio that provides create new classes such as data class etc......??
how can i use proguard? Should I set useProguard true in app gradle or android.enableR8=false in gradle properties
if i use zoom sdk and make magnify true is also change name to zoom library file at time of release
How about Flutter applications?
i found here, thanks Philipp
ask, Tell about Jiagu360?
what about the inner static classes (Like u said as Model class of josn ) which are inside the class which we have added pro Guard rule for not obfuscate this calss .*
does this means variable name which are in inner class also not obfuscated?
what are these at 09:31 , cubit class and bloc class? is this flutter related stuff or something else.
Sir,, Please help me.. I have faced a problem..
My app previous update version was only 10
megabyte. But now I have added some features,, the size jumped to 25 MB, which is not possible because I have added very small amount of code... When I cancled all and go to previous version by github using version control; it also showing 25MB in released version,,, which was 10MB..
"This App Bundle contains native code, and you've not uploaded debug symbols. We recommend that you upload a symbol file to make your crashes and ANRs easier to analyse and debug." whats this error?.. where I will get that file ?
I have firebase app with RecyclerView but when I release it into paly store, the app will crash... how to set proground for this problem?
What is Bloc class and Cubit Class?
where is the safe place to initialize API_KEY
How can I use mapping file through git to decrypt it
Bro I try multiscreen support using your tutorial but screen size set and not resize component bro.. How to set that
I dont know why but after this while generating signed apk ,,,i am getting stackoverflow error ,,,
wooooooww,
Proguard is not enough to secure your app. They can easily reverse-engineer your app. I hope you will create a tutorial more than this soon.
In terms of reverse engineering it's all you can do. You can't prevent that of course
I use proguard but app sizr not reduced
Type a.a.a.b.b.a is defined multiple times: help me, please
