我正在构建与DialogFlow和Firebase集成的聊天机器人。如何在Firebase LogCat中修复会话错误问题(如下所示(？是由于我的Android Studio中的问题还是我与Firebase的联系？我也遇到了膨胀我的回收器视图的问题，它使用FirebaseRecyclerAdapter膨胀了它。
-
firebase应用程序注册以连接到其服务器需要大量时间，所以我跳过了步骤，以为我会通过我的Google-json文件连接。
-
由于我正在使用firebase UI数据库v5.0.0，因此我必须根据此处给出的最新更新来更改firebaseRecyClerAdapter方法：https：//github.com/firebase/firebase/firebaseui-android/baseu-android/blob/blob/blob/master/master/database/readme.md

代码中有零错误，但是当我选择firebase时的logcat显示以下错误：
E/SystemUpdate-Connection: create session error : RESULT_ERROR
E/MiPicks-Connection: create session error : RESULT_ERROR
E/MiPicks-ConnectionRSA: get key exception : com.android.org.bouncycastle.util.encoders.DecoderException: unable to decode base64 string: invalid characters encountered in base64 data
，我也得到了回收clerviewException。错误可能是由于回收库不会被夸大的事实：

我可以直到这里。帮我！我死了！
firebase应用程序注册要连接到其服务器需要大量时间，因此我跳过了步骤，以为我会通过我的Google-json文件连接它。
重要的是，将您的应用程序注册到Firebase控制台，然后确保您的项目中有Google-Services.json文件。它包含API密钥和一些配置的东西。没有它可能会导致错误，例如您现在正在处理的问题。
似乎由于回收器的视图而出现了您的火箱错误。这意味着在Firebase开始其会话之前，应用程序崩溃了。
因此，我建议您首先修复回收即可通货膨胀错误。为此，请检查下面的库是否存在于您的应用程序级别build.gradle文件中。
implementation 'com.android.support:recyclerview-v7:28.0.0'
在这种情况下，由于我从Android迁移到Androidx，因此我不得不更改以前的RecyClerview IE的布局/activity_main.xml从 Yosi先生向我指出的android.support.v7.widget.RecyclerView至androidx.recyclerview.widget.RecyclerView。
因此，我更新的activity_main.xml文件：
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.internchatbot.MainActivity"
>
<androidx.recyclerview.widget.RecyclerView <!--change made here-->
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="10dp"
android:paddingBottom="50dp"
android:clipToPadding="false"
android:background="#f4f6f7"
/>
...
...
</RelativeLayout>
