冲突问题
androidx和support类冲突，具体如下：
Duplicate class android.support.v4.app.INotificationSideChannel found in modules core-1.5.0-runtime (androidx.core:core:1.5.0) and support-compat-27.1.1-runtime (com.android.support:support-compat:27.1.1)

解决办法
在工程中 gradle.properties 中加入配置：android.enableJetifier=true
说明
其实在出错的同时也有这么断错误：

Your project has set
android.useAndroidX=true, but configuration:player:debugRuntimeClasspathstill contains legacy support libraries, which may cause runtime issues.
This behavior will not be allowed in Android Gradle plugin 8.0.
Please use only AndroidX dependencies or setandroid.enableJetifier=truein thegradle.propertiesfile to migrate your project to AndroidX (see https://developer.android.com/jetpack/androidx/migrate for more info).
The following legacy support libraries are detected:
工具已经提示我们怎么处理了。工程已经配置了androidx，但又配置了support 的库，运行的时候可能会发生错误。请仅使用androidx的依赖或者在gradle.properties中添加android.enableJetifier=true将support库转换为androidx的依赖。
其次，个人在使用过程中，遇见了1.5 / 1.7的冲突，只有INotificationSideChannel和os.ResultReceiver两个类冲突。若不是可以配置android.enableJetifier=true将其转换，各种依赖查询，各种exclude要死人的。
