Does anyone know the what's causing "Package name is not a valid package name" when adding a new layout?

Question

I've receiving this error in every project I make, new or otherwise.

I've attempted reinstalling Android Studio fresh without any luck and I've also scoured the Internet for the exact error and nothing seems to be coming up.

Does anyone have an idea of what's causing this error when I add a new layout to my project?

Answer 1

Instead of adding the new activity by right clicking on the file labeled "layout", right click on the file labeled "res" to add a new activity and it should work fine.

Answer 2

As your screenshot shows,current package name is layout,but maybe you don't have a package named layout,so such error existed.

If you want to add a layout file to your project,you should right click layout folder under res folder,and create a layout file.

Hope this helps

Option 1:

1. Click the Project tab. From there you can see a dropdown. Click the dropdown and go to Packages and then you can see the layout folder. From there you can create another Blank Activity.

Option 2:

1. From the dropdown again go to Android. Click the java folder, you can see the package name com.example... Write it down on a paper. Then go to layout and create a blank activity. Change the package name to what you had just wrote down on the paper.

Hope it helps.
