I received a sudden "cannot resolve symbol R" error, after I did everything exacty on the video and tried to run the app

I searched the internet to find a solution, yet there seemed to be not a single cause or solution for this.

Hello Deniz Beser,

Sometimes this can happen. There are a couple of things that you can try to see if it fixes the problem. The first would be to just restart Android Studio.

If that does not work you can go to the Build menu and select clean build. That will rebuild the project and should create a new R resource.

Hope that helps!

Errors seemed to dissappear at first, but onceI tried to run the app, they all showed up again despite the actions you mentioned. Shall I send parts of my code; if so, which? Thanks for help Sam Wilskey!

Does the R in android studio have a red squiggly line underneath it? If it does what does it say when you mouse over it?

No, the capital R is entirely red. when I mouse over it it says "Cannot resolve symbol R."
