Android Studio | Unable to run newly created project(s)

Question

Since recieving the latest update from Android Studio (AS), my project was no longer able to run. After dealing with a few of the 30+ IDE errors I found manually cloning the entire project to be more efficient.

Though, when I create a new empty project it is not able to run due to the following error:

Could not identify launch activity: Default Activity not found

So I tried the 2nd and 3rd suggestion offered by this thread:

Error: Default Activity Not Found

But this made no difference.

Then I have reinstalled Android Studio, but unfortunatly without any improving results.

So now when I want to run any newly created project, it tells me it cannot find a registered activity. As one can see in the image, the activity is registered in the manifest.

I am hoping for new things I can try so I can finally move on with my work.

First thing I have done, but thanks for the suggestion – MwBakker Oct 23 '18 at 10:45 — MwBakker, Oct 23 '18 at 10:45

Been there, done that. This issue unfortunatly goes a little deeper – MwBakker Oct 23 '18 at 10:58
1: create new layout "NewActivity" 2: replace .MainActivity to .NewActivity – Shams Sheikh Oct 23 '18 at 11:06
Didn't do the trick either, the settings have been too messed up somehow – MwBakker Oct 23 '18 at 12:11

I got it fixed by following the instructions of this post:

What worked for me is to remove (or you can move it as a backup) the ".AndroidStudio3.2" (for you it will be .AndroidStudio3.1) folder located in "C:\Users{username}\" and then reopen the Android Studio.

While launching I selected to import settings from the last version and proceed. it will reconfigure all the settings.
