It is showing error here
FirestoreRecyclerOptions<firestorereycler> allfirestorerecycler= new FirestoreRecyclerOptions.Builder<firestorereycler>()
.setQuery(QueryApni.firestorereycler.class)
.build();
I am using this library
implementation 'com.google.firebase:firebase-core:17.2.2'
implementation 'com.firebaseui:firebase-ui-auth:6.2.0'
If you add libraries , you will not get an error.
Go to AndroidStudio -> Tools -> Firebase -> Cloud Firestore. And follow steps. Everything will set automatically.
In addition , add this to build.gradle(Module:...) -> dependencies -----> implementation 'com.firebaseui:firebase-ui-firestore:7.1.1'
After these steps . Everything will be ok. I managed to run it after following these procedures.
As mentioned in Official Documentation setQuery() requires 2 arguments, a query and a class.
FirestoreRecyclerOptions<firestorereycler> allfirestorerecycler= new FirestoreRecyclerOptions.Builder<firestorereycler>()
.setQuery(<QUERY>,QueryApni.firestorereycler.class)
.build();
