Error occurs after I have uploaded icons for app (in Android Studio with Flutter)

I have created app icons with a website called appicon. It provided icon files for both android(mipmap files) and ios devices(an Assets.xcassets file), which I added to their respective locations being (C:\Users\user\StudioProjects\i_am_rich(name of app)\android\app\src\main\res) for android and (C:\Users\user\StudioProjects\i_am_rich\ios\Runner) for ios.
When I run the program the following error is displayed:
FAILURE: Build failed with an exception.
* What went wrong:
Execution failed for task ':app:processDebugResources'.
> A failure occurred while executing com.android.build.gradle.internal.tasks.Workers$ActionFacade

I am learning Android Studio as the IDE with flutter, as a beginner, so I don't understand the problem nor what I have to do to fix it.
Help and, possibly, an explanation would be greatly appreciated :)

The website you mentioned does generate correct names and correct order of directories it seems. so most probably this is an issue with where you have put your files or the name of the files.
The 5 directories of icons must be copied to android\app\src\main\res folder.
and make sure in each directory you have a file called ic_launcher
if all is correct, please run flutter clean command and try again.
also by anychance the webisite generating incorrect files, try using this web site AndroidAssetStudio

stuck to resolve this error.
Help me to resolve this error.

this problem happened in windows because of slashes
in your project folder navigate to android and open local.properties file
replace
sdk.dir=C:\Users\\<userName>\AppData\Local\Android\Sdk
with
sdk.dir=C:\\Users\\<userName>\\AppData\\Local\\Android\\Sdk
and it will work correctly

Try to use this version
"react-native-reanimated": "2.0.0-rc.3"
It's worked to me.

For me, updating to reanimated#2.11.0 fixed my compile error
I am using react-native 0.69.3.

As mention earlier this work
sdk.dir=C:\\Users\\<userName>\\AppData\\Local\\Android\\Sdk

Build failed: directory does not exist

Had a working project on a PC.

Android Studio R Cannot be Resolved - Error on Clean and Gradle Build

I am currently working on an app for my own personal use but have 1000001 problems with Android Studio - now R cannot be resolved - and cleaning gives the result below:

Above is the error message I keep on receiving when I clean my project. I can't find any XML errors, I have no foreign bodies in my resources except the launcher picture, and I can't find my R file anywhere - let alone reference it without error. The above error points to a
abc_textfield_search_activated_mtrl_alpha.9.png
That I have found and deleted - I don't think this is the right solution as the error persists. I have update Android Studio synched the Gradle and everything I have seen from my research. I really don't know how to handle this.
Thank you.

My first android program build fails. Error: The system cannot find the path specified

The error messages copied from android studio are as follows:
FAILURE: Build failed with an exception.
What went wrong:
Execution failed for task ':app:dexDebug'.

I previously used the eclipse IDE, appeared the same error message, which is "The system cannot find the path specified".
And I searched nearly all the similar question from the web, the problem not solved yet.
The IDE internally use some .bat file to find the java.exe location, but my .bat file not function for some reason unknown.
So I suspect the problem comes from my another problem:
My bat file can't run correctly, why?
