processDebugResources FAILED after changing icon launcher - reactjs

Question

I change launcher icon in this address:
Projects\nameproject\android\app\src\main\res
And then linked them by this command:
npx react-native link
after re-building project by this command:
react-native run-android
I am getting following error:
> Task :app:processDebugResources FAILED

I ran gradlew clean but issue is persisting:
Does anybody have any idea how can i fix this?

Answer 1

I faced this same issue. It is because react-native android app icons run in round shaped. It shows build/ processDebugResources failed because we didn't add circle shaped app icon in res folder.
First, after creating a fresh project, look in the android/app/src/main/res folder, you will find ic_launcher & ic_launcher_round, right?
So, I suggest you to go Launcher icon generator to make two shaped icons (circle and square), paste them in icon folders with same name(ic_launcher & ic_launcher_round) and build the project.
You will find that app icon is updated.

Answer 2

I just copy ic_launcher and past it to same folder as ic_launcher_round. for example in mipmap-hdpi folder i just have an ic_launcher file and I manually copy and paste this, then run cd android && ./gradlew clean and run npx react-native link in root folder again, then rebuild the project again with npx react-native run-android command.
