我还尝试了这个答案Android 10 Activity onCreate Crash 中提到的解决方案，方法是将这些依赖项添加到我的项目中
// Annotation processor
annotationProcessor "androidx.lifecycle:lifecycle-compiler:2.2.0-alpha05"
// alternately - if using Java8, use the following instead of lifecycle-compiler
implementation "androidx.lifecycle:lifecycle-common-java8:2.2.0-alpha05"
implementation "androidx.lifecycle:lifecycle-runtime:2.2.0-alpha05"
implementation "androidx.lifecycle:lifecycle-process:2.2.0-alpha05"
implementation "androidx.lifecycle:lifecycle-service:2.2.0-alpha05"
但这没有帮助。
【问题讨论】：
【参考方案1】：查看崩溃日志：
Caused by: android.view.InflateException: Binary XML file line #17 in com.aia.portercustomer:layout/abc_screen_simple: Error inflating class androidx.appcompat.widget.FitWindowsLinearLayout
在您的 app.gradle 中，添加以下内容：
implementation 'io.github.inflationx:calligraphy3:3.1.1'
implementation 'io.github.inflationx:viewpump:2.0.3'
