我在 Android 5.0 (API 21) 上进行测试时出现以下错误。在其他操作系统版本上测试效果良好。
java.lang.RuntimeException：无法启动活动
ComponentInfo{...ui.activities.navigationActivity.fragments.legalFragment.LegalDetailActivity}：
android.view.InflateException：二进制 XML 文件行 #24：错误
膨胀类 android.webkit.WebView
在第 24 行，找不到任何关于 xml 布局的特别之处：
<WebView
android:id="@+id/nav_fg_legal_detail_web"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
代码：
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setTheme(R.style.AppTheme_NoActionBar)
setContentView(R.layout.legal_detail_activity) // crash here. Nothing done to web view yet.
我正在使用库“androidx.appcompat：appcompat：1.1.0”。
Update：
完整堆栈：

2020年4月24日，我用以下方法解决了这个问题：
implementation 'androidx.appcompat:appcompat:1.2.0-beta01'
上一个和不工作版本如下：
implementation 'androidx.appcompat:appcompat:1.1.0'
