Unresolved Reference to any class from kotlinx.coroutines. package - android-studio

In an android Studio Project I received where kotlin coroutines library is added as dependency
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-android:1.3.8",
implementation "org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.8",
Although everything builds and runs perfectly well, in Android Studio itself I see Unresolved Reference Errors on every import of a class from kotlinx.coroutines package.
And in my External Libs folder the jar file for corouties core seems not to have appropriate files: see screenshotsenter image description here
I searched the internet and tried various things that I could find but there is very few information on this topic and I nothing helped me

EDIT:
I seem to have found the culprit. It appears to be the kotlin.mpp.enableGranularSourceSetsMetadata=true in the gradle.properties file. When I commented it out the libraries imported properly and the classes work as expected.
I filed an issue on issuetracker.google.com:
END EDIT
I'm having the same issue using org.jetbrains.kotlinx:kotlinx-coroutines-core:1.5.1-native-mt.
It's not clear where I would post a bug report...
Creating a new project and adding just adding coroutines has not reproduced the issue. So I have seen it work. My best guess at the moment is that it's some sort of conflicting dependency or dependency that causes a problem with AS pulling in the external library jar and sources.
Here is the project external libraries where it is not working. Image showing external klibs for commonMain, nativeMain:
And here is the one that works properly. Image showing coroutines-core with source and metadata:

Some of megasparkDiff libraries are not importing

I have cloned the MegaSparkDiff project from GitHub and just wanted to try it out. I use IntelliJ IDE, the project has sample examples and different libraries. Unfortunately, some libraries are not getting imported
I have tried to reload maven, deleted this project, and re-cloned again, but I am getting the same problem, which these libraries/classes are not getting imported :
import org.finra.msd.sparkcompare.SparkCompare;import org.finra.msd.sparkfactory.SparkFactory;
import org.finra.msd.containers.AppleTable;import org.finra.msd.containers.DiffResult;
so, how can I resolve this issue?

unresolved reference: fillMaxSize() and unresolved reference: size() error in android studio with Kotlin

I started very basic android development and from the very first day it seems that android studio and kotlin are just like a bundle of problems. Like after first installation of androidstudio I build the basic samples on Kotlin and it worked fine. After few hours I got a notification on androidstudio about some update so I did it and then every thing stopped working I looked for solution on Internet and tried for 2-3 hours but didn't get it back working. Then I uninstalled everything related to androidstudio on my PC and re-installed it and then it started to work again.
After few days I started to implement a tutorial and I used the same code and configuration described in tutorial but on the very first step where they just created a basic sample application without any thing and it started to show errors like Unresolved reference: fillMaxSize and Unresolved reference: size and I couldn't find any solid solution on Internet and surprisingly found out that internet is full of these kind of issues on androidstudio.
In the project I am using the function fillMaxSize() in another file where it works 100% fine but in the same project but in different file it gives error. Can anybody give a solution to this?
Apart from this I just want to ask that is android development in general is like this? That every time you go 1 line further and you see new errors and then you have to spend hours on internet and look for solutions and you then found tons of queries about these errors on internet and nothing is clear and particularly working for your case but it is kind of similar error_
Adding new imports, changing plugin versions, adding plugins, changing dependencies and versions.
After few hours I got a notification on androidstudio about some update so I did it and then every thing stopped working
Updates of course are good as they try to fix or enhance something. However, some updates will add, remove or change some previous working functions to achieve the fixing or enhancing purpose. And that's why some programs require certain version of Software instead of always the latest one to run.
In the project I am using the function fillMaxSize() in another file where it works 100% fine but in the same project but in different file it gives error
In this case, you will have to check whether you have really added the corresponding import to that particular file. If there is really configuration problem, it should not have worked in one file but not the other. import is something that you have to do in every file using that function.

Android Studio xmlns Error Debugging

I'm getting the following error compiling a program using a 3rd party library:
Error:(xx) No resource identifier found for attribute 'tint' in package 'com.example.mycompany.myapp'
The line xx is inside the xml layout that includes a custom component defined in the library.
cntrlco:tint="42"
The xml namespace documentation says I need the following:
xmlns:cntrlco="http://schemas.android.com/apk/res-auto"
Here's my best guess as to the problem, but if you think otherwise please let me know, this is a guess.
I suspect I don't have the library installed completely. The reason is that the library instructions want the library installed from maven. I'm not up on this technique, but it appears to be a web based auto install that automates dependency installs while performing the primary install. Nice idea, but I can't install using the web (long story), so I included the .aar file locally.
From my research, installing .aar files locally won't look at its dependencies. If this is true and the "tint" property is defined in a dependency, then this would explain the error I'm seeing.
Is there a way to follow the error chain in more detail so I can verify my theory? Along the way, will this help me find the name of the possible missing dependencies so I can see if including them fixes the problem.

different between ServiceStack.Interfaces.dll and ServiceStack.ServiceInterface.dll

Recently I am working on servicestack project. When I am trying to add open ServiceStack.ServiceInterface in project it is showing below error.
PFB image for code.
As suggested in error, when i am trying add open ServiceStack.Interfaces then it is showing dll is not present.
please tell me why it is showing error?
What is different of this two DLL?
ServiceStack.ServiceInterfaces contains interfaces used by the ServiceStack webstack while ServiceStack.Interfaces is used by the various other ServiceStack projects (like OrmLite) as well.
ServiceStack.ServiceInterfaces depends on ServiceStack.Interfaces, which means you have to install it as well (it is a seperate nuget package)

I am having difficulty getting a new version of a 3rd party SDK to import into Android Studio

I am having difficulty getting a new version of a 3rd party SDK to import into Android Studio.
In the earlier version they released .jar and .so files which I copied into /lib and /jniLibs and then added the lib files into the Android Studio app and everything worked. The app ran, used the libraries and all was good in the world. Recently a new version of this SDK was released but in this new release they have resource files (but they are not compiled into the jar/so files; there is a $Rstring.class files that they say I should import. I've now spent days copying into various locations in the app project with no luck and the missing strings result in crashes when calling their SDK.
OK, I figure I'd try to import their SDK folder (which is how they document to do it if you are using Eclipse). Well, no matter what I've tried and after selecting the folder or SDK's project file I get a dialog asking for the Eclipse workspace and a list of what appears to be source file names. I can't get past this dialog because obviously I don't have their files.
Has anyone run into this and found a solution; perhaps I'm missing something in the process but after spending the better part of 3-4 days trying and searching and trying more things I'm hopeful for help from the community.
OK, I found the answer and it was a combination of issues in how this particular 3rd party distributed the SDK and not fully understanding the menu.
The 3rd party in question packaged the SDK with the output files of the build as well as files that needed to be imported making an import alone to not work.
Combine this with menu confusion: File->Import Module is NOT the same as New->Modules->Import Existing Project only added to the confusion.
The solution ended up being to use the File->Import Module which appears to be a very different operation and once done most of the issues where solved. It solved the main issues I asked above which was missing resourced.
Still missing was the library (.jar) files which had to me copied into the app's lib folder and "added as library" but the .SO files did not need to be copied and in fact doing that resulted in a duplicate files warning.
I'm not sure I can fully explain what happened but what I think happened is that the "module" was where the app read the .so and string resources from but was unable to load the .jar files because (I suspect) these files where not part of the module but rather where outputs of building the source and it was removing the source files which caused the inability of the new->Module->Import to fail.
Hopefully this makes sense or at least give someone an idea of what to look for when/if they run into a similar issue.
