java ClassNotFoundQueryListenOptions异常

Question

After upgrade latest version implementation 'com.google.firebase:firebase-firestore:16.0.0'

implementation 'com.google.firebase:firebase-firestore:16.0.0'
implementation 'com.google.firebase:firebase-auth:15.1.0'
implementation 'com.google.firebase:firebase-database:15.0.0'
implementation 'com.google.firebase:firebase-storage:15.0.2'
implementation 'com.google.firebase:firebase-appindexing:15.0.0'
implementation 'com.google.firebase:firebase-messaging:15.0.2'
implementation 'com.google.firebase:firebase-functions:15.0.0'
implementation 'com.google.安卓.gms:play-services-gcm:15.0.0'
implementation 'com.google.安卓.gms:play-services-auth:15.0.0'
implementation 'com.google.安卓.gms:play-services-maps:15.0.1'
implementation 'com.google.安卓.gms:play-services-location:15.0.0'
implementation 'com.google.安卓.gms:play-services-places:15.0.0'
implementation 'com.firebaseui:firebase-ui-firestore:3.3.1'
implementation 'com.firebaseui:firebase-ui-database:3.3.1'
implementation 'com.firebaseui:firebase-ui-auth:3.3.1'
implementation 'com.firebaseui:firebase-ui-storage:3.3.1'

以下代码：

FirestoreRecyclerOptions options = new FirestoreRecyclerOptions.Builder<Inventory>().setQuery(query, Inventory.class).build();

Inside setQuery(),it shows Cannot resolve symbol 'QueryListenOptions'

如何解决上述问题

Answer 1

{a1}解释了这种变化：

Replaced the DocumentListenOptions and QueryListenOptions classes with a MetadataChanges enum. Instead of calling addSnapshotListener() with either of those classes, use the enum:

addSnapshotListener(MetadataChanges.INCLUDE, ...)

截至5月3日，Firestore文档尚未更新，包括MetadataChanges。作为参考，这是反编译的类文件：

package com.google.firebase.firestore;

public enum MetadataChanges {
    EXCLUDE,
    INCLUDE;

    private MetadataChanges() {
    }
}

更新 FirebaseUI version 3.3.1是使用Firebase SDK版本15.0.0构建的。它与Firestore 16.0.0不兼容。因为您使用的是FirebaseUI 3.3.1，所以必须使用Firestore 15.0.0进行构建

Answer 2

尝试在所有firebase依赖项中使用相同的firebase版本

已编辑

在上一个firebase版本中，您不需要使用相同的版本号
