Android Studio: clang error: unknown argument: '-mandroid'

I am trying to build a project with NDK and cannot get rid of this error. I searched all over the google but a similiar error is only there for Xamarin. I am using Android Studio. The error is all about:

It seems that this related issue won't be fixed by the android-ndk folks:
Openssl (1.0.2g) adds -mandroid to the compile flags. This flag is not recognized by clang (clang38: error: unknown argument: '-mandroid'). Since it's a known gcc flag, I expect other libraries would do the same.
https://gcc.gnu.org/onlinedocs/gcc/GNU_002fLinux-Options.html provides the details for what that flag does in gcc. I'm not sure if this belongs here or as a clang issue, but I wanted to bring up this potential compatibility problem.
.
Talked with our clang folks. There isn't any point in supporting this flag in clang since the -target flag covers it already.
At some point in the (hopefully near?) future we're going to be shipping the compilers as wrappers so that we can make sure standalone toolchains, NDK build, and gradle builds all behave the same, and those wrappers could filter out unknown flags too.

I have tried everything that could be Googled. I've tried even downgrade versions of SonarQube gradle plugin and JaCoCo to 2.0.1 and 0.7.6.201602180812

Device was the problem. I was running it on Samsung J7,S8 and it was giving same error. When I ran the same on Pixel2 then task ran successfully and able to see coverage percentage in sonar server.

Gradle project throwing NullPointerException within Gradle process

I have been working on an android studio project for a while now and suddenly, today I started getting an error while trying to build the project.
The build process throws a NullPointerException and I cannot figure out why for the life of me. This is the stack trace that I get, which doesn't even give me a hint about my problem.
Could you give me some pointers?

I had the same issue today, and the only thing that worked for me was to delete the .gradle directory from my project directory...

I was getting the same error after upgrading the project to Gragle 7. The cause was outdated plugin. I replaced it with a newer version:
id("com.github.maiflai.scalatest").version("0.26")
id("com.github.maiflai.scalatest").version("0.31")

Go to File -> Invalidate Cache / Restart
If that does not help, Restart your PC and then press Ctrl+F9to build the project (it does it once again).
It can be found in the menu Build -> Rebuild Project

I faced this many times ..
What I am used to do to solve this issue:
(bit-by-bit)
Rebuild Project
Clean Project
Invalidate caches / Restart
In case you are using Gradle deamon. stop it by ./gradlew --stop and start over the steps from 1 to 3
Finally & destructively close Android Studio completely and delete .gradle directory ( it's hidden ) from the root of directory of your project and then launch Android Studio again.
Hope that may help,'.

Above didn't work for me but disabling instant run did
Search instant run as follows:
CMD+SHFT+A
Search instant run and disable it.
Rebuild and run.

Error: cannot find symbol class Builder (using Retrofit)

BUILD FAILED
Total time: 1.351 secs
Would appreciate any help on this

I've tried your code, and the Buider is not recognized this way you are doing.
Try this:
public static final String BASE_URL = "http://api.myservice.com";
public RestAdapter providesRestAdapter(Gson gson) {
return new RestAdapter.Builder()
.setEndpoint(BASE_URL)
.build();
}
Of course, this method goes inside some class. Think this class as a Module/RestClient where you configure your api. So, you can name this class AppModule, RestClient or another name you prefer.
Below, some tutorials that can be useful:

Execution failed for task 'app:mergeDebugResource'

I'm getting this "Execution failed for task 'app:mergeDebugResource'" error every time I try to build or clean my project. I have reinstalled Gradle, Java, Android Studio, and all of the SDKs several times, so it's not that. And none of the answers on StackOverflow seem to be helpful. I'm trying to learn Android development but can't because of this error. Please help!

BUILD FAILED
Total time: 14.776 secs
Thank you!!

Execute this in terminal window and see,
gradlew clean build --refresh-dependencies

I had the error when installing new packages on my RN app.
I fixed the error by running
cd android/ && ./gradlew clean build --refresh-dependencies`
then
cd ../
again
react-native run-android
