I was wondering how to change the launcher icon in Android Studio.
Try this process, this may help you.
***** NB: Icon type should be Launcher Icons (Adaptive and Legacy) *****
All the download process is too long, just navigate to your project preview and select project view, right click on app folder, then click on new, then create a new image asset. Kindly choose the file path and click next and finish.
important: Reinstall your app.
