Firestore Tutorial Part 9 - SIMPLE QUERIES - Android Studio Tutorial

In part 9 of the Firestore tutorial we filter our queries by calling a where method on our CollectionReference, like whereEqualTo or whereGreaterThanOrEqualTo. Into these methods we pass the key of the field in the document, and the value we want to filter for.nWe can also order these results with the orderBy method, where we can pass Query.Direction.DESCENDING to get our results in descending instead of ascending order.nLastly we will use the limit method to only retrieve a certain number of results.nWe can add all these queries before the get method or before the addSnapshotListener method.nnWatch the whole playlist:nwww.youtube.com/playlist?list=PLrnPJCHvNZuDrSqu-dKdDi3Q6nM-VUyxDnnExample code, setup guide link etc:ncodinginflow.com/tutorials/android/cloud-firestore/part-9-simple-queriesnn____________________nSubscribe to my channel:nwww.youtube.com/c/codinginflow?sub_confirmation=1nnWant more Android tutorials?
