Hey there, I recently tried the demo codelab-android-paging/tree/main/advanced/start, and found the list always empty, according to the latest official document the reason is the apiQuery used in both start and end project missed a + between query and IN_QUALIFIER:

as in the start project:

IN_QUALIFIER:

apiQuery:

if we input a query as "Android", the final network request URL will be "https://api.github.com/search/repositories?sort=stars&q=Androidin%3Aname%2Cdescription&page=1&per_page=30"

and the result:

{ "total_count": 0, "incomplete_results": false, "items": [ ] } 

after we add a + :

"https://api.github.com/search/repositories?sort=stars&q=Android%2Bin%3Aname%2Cdescription&page=1&per_page=30"

and the result:

{ "total_count": 64, "incomplete_results": false, "items": [ ... ] }
