Example 2 with IndexBackfiller

use of com.google.firebase.firestore.local.IndexBackfiller in project firebase-android-sdk by firebase.

the class FirestoreClient method initialize.

private void initialize(Context context, User user, FirebaseFirestoreSettings settings) {
    // Note: The initialization work must all be synchronous (we can't dispatch more work) since
    // external write/listen operations could get queued to run before that subsequent work
    // completes.
