Exception: OBSOLETE - Providing Android resources in Assets/Plugins/Android/assets was removed

I use 2021.2.0b12.3482. Right after update it became unavailable to build an android version because of error. Notice that Assets/Plugins/Android/assets contains the same 2 files sa before. AAR files are also here.

Code (CSharp):

1. Exception: OBSOLETE - Providing Android resources in Assets/Plugins/Android/assets was removed, please move your resources to an AAR or an Android Library. See "AAR plug-ins and Android Libraries" section of the Manual for more details.

Please help, I am having this issue too.

 

Haven't fixed. 2021.2.01 stable. still not able to build for android.

 

What is the problem is that this error is caused by Unity itself. In my case, it is by UDP.
I got 2021.2.3f1 and UDP 2.2.3
UDP is creating this folder where GameSettings.prop is located.
I hope they will fix it soon.

 

2021.2.3f1 doesn't fixed.

 

bump

Found any solution? Having the same issue

 

Found any solution? Having the same issue

 

what if just change the version of the unity? could smth change?

 

Hi , I tried to integrate Chartboost ads in my Unity Project.I got this error, Then I went to Services->UDP. In the package manager I used the latest UDP 2.2.5. But still getting the same error.

 

same

 

Any solution? I don't use UDP and I'm having this bug when I try to build to Android. Unity 2021.3.2f1

 

plz resolve this issue

 

Deleting the "Assets" folder in "\Assets\Plugins\Android\" seemed to fix it for me

 

You can't just delete android's plugin folder. It contains as dependency files and resources you need to build an Android version.

 

Packing your resources to .aar file could solve this problem. For more details see
https://docs.getsocial.im/knowledge-base/pack-resources-to-aar/

 

A exclusão da massa "Ativos" em "Ativos/Plugins/Android" funcionou perfeitamente

 

The real solution of course is to change from Unity to Unreal Engine. Everything in Unity is always broken. It's their business model.

 

This same fix worked for us as well - don't delete the entire Android folder, just the Assets folder under Android in Plugins. Keep the libs folder in Android as is. Then you can do the build.

 

The easiest solution for me was creating a folder named 'myLibrary.androidlib'. I copied the resources to their respective subfolders 'myLibrary.androidlib/res/values' and 'myLibrary.androidlib/res/xml' (my issue was with a network_security_config.xml resource) I also made a simple AndroidManifest at the root of the new android library folder.

 

While deleting this folder does allow the build to complete, the resultant APK file is corrupt. Attempting to load it gets the error "There was a problem parsing the package".

I'm seeing this issue on Unity 2021.3.8f1 after upgrading from Unity 2020.2.38f1. Android builds went fine on 2020; they fail with the "Providing Android resources in Assets/Plugins/Android/assets was removed" message in 2021. The Assets/Plugins/Android/assets directory contains a single file, GameSettings.prop, with a single line containing a string of apparently random characters, surrounded by comments (in all caps) saying "*** DO NOT DELETE OR MODIFY THIS FILE !! **". This warning seems accurate, given that removing the file results in an unusable APK.

I'm on UDP 2.2.5, which is apparently what has created this file. Has anyone successfully moved it to an aar? If so, what is the process?

 

Hey Dtootill, did you manages to solve it? I'm having the same issue and i've got no idea on how to solve it...

 

Thank you this solution works for me

 

Im also seeing this error. Very odd behaviour when 2020 was fine.
What exactly is Unity asking us to pack into this "arr"? The entire plugins folder, the "res" folder?

Some clarity would be appreciated, or better yet, a fix.

 

I faced this issue while import the Chartboost SDK to unity project 2022.1.3. This solution is simple and work for me !! Thanks so much !!

 

This worked for me

 

Thank you for updating it works for you.
I just upgraded from 2019 to 2021 (the latest TLS) and encountered this error, i tried to delete the assets folder on \Assets\Plugins\Android\ but still receiving this error, can you just explain what did you exactly do to solve it? because I don't know which plugin is causing this...

 

Hello,

Any other fixes for that? I am still encountering this issue on Unity 2021.3.14f1 LTS..
Thanks!

 

This error's causes and solutions are here.
https://docs.unity3d.com/2021.2/Documentation/Manual/UpgradeGuide20212.html

The reference way for android assets has changed, and we need manually modify this folder.
We have two solutions.
a. res.aar
Zip Android/res and change the extension to aar.
b. res.androidlib
Create the following two files, move them to Android/res, zip res, and change the extension to androidlib.

AndroidManifest.xml

Code (CSharp):

1.  
2. <?xml version="1.0" encoding="utf-8"?>
3. <manifest xmlns:android="http://schemas.android.com/apk/res/android"
4. package="custom.android.res" android:versionCode="1" android:versionName="1.0">
5. </manifest>

project.properties

Code (CSharp):

1.  
2.     target=android-9 android.library=true
3.  

I could built with b. aar did not work.
The original AndroidManifest creates a new res folder, so move it to tmp folder during test build.

 

Thank you. Your solution worked for me. And for the next person looking for solution for this problem atleast open the link once he provide to get more details then only this problem can be solved.

 

Hey, could you please provide more information on this?

 

hello, this is how i fix res folder (my res folder added because chartboost sdk)
move your xml folder (inside plugins/android/res) to
myproject\Library\Bee\Android\Prj\IL2CPP\Gradle\launcher\src\main\res
don't forget to delete .meta file inside xml folder

 

Anyone

Thanks, here is the extended version , which also works on assets folder.

https://github.com/Frismos/UnityUtilsHelpers/blob/main/AndroidResAssetsUpgraderPostprocessor.cs

 

This worked for me but then lead me to a "Type com.unity3d.player.BuildConfig is defined multiple times" error in Android Studio (I already have an AndroidManifest in Plugins > Android.) I'm sure I've written something wrong in the "simple AndroidManifest" you mentioned. Could you please provide a complete example of the simple AndroidManifest you mentioned for the network_security_config.xml?

 

thank you @skeyll
solutions b work for me also

 

Tried all the solutions here, and this one was the only who worked for me.
My issue was that I've upgraded to Unity 2021.3, and I received this message while building: "Exception: OBSOLETE - Providing Android resources in Assets/Plugins/Android/assets was removed".

Tried the res.aar and res.androidlib, but then another message: "resource 'string/fb_login_protocol_scheme' not found", as if the strings.xml was gone or not found. But the AndroidPluginsUpgrader.cs script worked and my build was successful.

 

Deleting the "Assets" folder in "\Assets\Plugins\Android" fix it for me in unity 2021.3.21f1

 

thanks, the aar worked for me but i had to delete the res folder and res.meta.

 

that`s good!

 

I got and error while using your method with script: Resource 'xml/file_paths' not found in AndroidManifest.xml:47,
(See the Console for details). As i understand AndroidManifest doesn't see file_paths.xml that is in res-legacy/xml/

 

still getting a problem like this.
EDIT 1: using the provided "semi-automatic method" is building something!
EDIT 2: nope, build failed.
EDIT 3: after various test build succeeded, but I can't pinpoint out a reason.
