Android Question Compilation error from modified FusedLocation provider example

What I'm trying to achieve: Add file sharing (exporting) feature to the FusedLocationProvider example.
What I've done:
1. Ran both shareFileWithFileProvider and FusedLocationProvider examples separately without any problem.
2. Copied code from FileProvider to FusedLocation example

The compilation error I've got:
<code>

</code>

Test app is here

Any help would be greatly appreciated.
