“android.annotation.NonNull"在“android.annotation"中不是公开的.无法从外部包访问 [英] 'android.annotation.NonNull' is not public in 'android.annotation'. Cannot be accessed from outside package
问题描述
当我尝试列出数据时收到此警告.有谁知道为什么?
您指的是 Android 平台的内部注释,这些注释不是您想用于自己的代码的注释.对于您的代码,您应该导入这些注释的 AndroidX 版本:
等等.(注意 androidx
和 android
中额外的 x
)
您还需要确保在 build.gradle
中声明了对 androidx.annotation:annotation
的依赖(请参阅 这里 最新版本信息)
I get this warning when I try to list data. Does anyone know why?
You're referring to the Android platform's internal annotations, which aren't the ones you want to use for your own code. For your code, you should import the AndroidX versions of those annotations:
etc. (note the extra x
in androidx
vs android
)
You'll also want to make sure you have declared a dependency on androidx.annotation:annotation
in your build.gradle
(see here for the latest version information)
