将项目更新为android 10之后，我在HomeActivity上崩溃了，该应用程序在较旧版本的android上正常运行，但是当我使用Android 10设备时崩溃了，我进行了启动活动，并且运行正常，但是崩溃发生在转到onCreate setContentView（R.layout.activity_home）;
上的家庭活动这里是崩溃报告：

还通过将这些依赖项添加到我的项目中，尝试了此答案Android 10 Activity onCreate Crash中的solutuin提及
// 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"
但是没有帮助。
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'
