将现有项目传递给 androidx 给了我无法解决 com.google.android:support-v4:r11

Question

我正在将代码更改为 androidx，但在我尝试 gradle sync 时出现以下错误：

ERROR: Unable to resolve dependency for ':Debug/compileClasspath': Could not resolve com.google.android:support-v4:r11.
Show Details
Affected Modules: AppName

ERROR: Unable to resolve dependency for ':DebugAndroidTest/compileClasspath': Could not resolve com.google.android:support-v4:r11.
Show Details
Affected Modules: AppName

ERROR: Unable to resolve dependency for ':DebugUnitTest/compileClasspath': Could not resolve com.google.android:support-v4:r11.
Show Details
Affected Modules: AppName

我尝试过的事情： 1：进入文件->其他设置->默认设置->构建，执行，部署->构建工具->Gradle->取消选中离线工作选项。 未选中脱机选项。

2. 使缓存失效并重新启动。这什么也没发生，出现同样的错误。

清理项目/

3. 重建项目/使用gradle文件同步项目/重新启动Android工作室。出现相同的错误。

格拉德尔文件

解决方案：这是一个库不兼容的问题。 将org.parceler：parceler实现更改为新版本并检查所有库是否具有最新版本，错误已消失

尝试删除此行，添加

implementation 'androidx.appcompat:appcompat:1.1.0-rc01' 

并检查其他工件设置正确：https://developer.android.com/jetpack/androidx/migrate
