Answer 1

I had below error

error:  inner element must either be a resource reference or empty.

In my case I created new test project and deleted the toolbar and fab from activity_main.xml file but these were also in ids.xml file. After deleting both ids from ids.xml file I was able to run. In your ids.xml file you may have lots of ID's but as I created a new project So, It has No IDs.

In above screenshot you can see the exact file location.
