我迁移androidx之后,当我单击按钮时它会显示给我 为什么会这样?
当我单击按钮打开日历时我想做什么
这是我单击按钮时遇到的错误
java.lang.ClassNotFoundException: Didn't find class "com.example.blogapp.whateverString" on path: DexPathList[[zip file "/system/framework/org.apache.http.legacy.boot.jar", zip file "/data/app/com.example.blogapp-BjDX
这是我的Manifest.xml,whatString是从哪里来的
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.together">

tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
android:allowBackup="false"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:roundIcon="@mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="@style/AppTheme"
android:usesCleartextTraffic="true">
我使用这两行
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
因为我被添加了以下实现
implementation 'androidx.appcompat:appcompat:1.0.2'
implementation 'com.google.android.material:material:1.1.0-alpha07'
implementation 'joda-time:joda-time:2.10.1'
从这里我看到有人在mycase中使用以下代码建议发生错误
tools:replace="android:appComponentFactory"
android:appComponentFactory="whateverString"
所以这就是我使用“ WhateverString”的原因
我该如何解决这个问题? 我不明白为什么在迁移androidx后突然向我显示错误
