升级 android 版本后得到“重复类 android.support.v4.app.INotificationSideChannel”

Question

在 android update 3.4 之前，我的应用程序运行完美，但在升级 android 之后，我的应用程序出现合并错误：

 "Duplicate class android.support.v4.app.INotificationSideChannel"

android update 3.4
upgrade gradle 5.1.1
upgrade sdk

Answer 1

您有 androidx 库（可能在使用的库之一中）与 support 库冲突。

将这些行添加到您的 gradle.properties 文件中：（它位于项目的根目录中）

 android.useAndroidX=true
android.enableJetifier=true

Jetifier 工具迁移依赖于支持库的库以依赖等效的 AndroidX 包。
