android - 为什么 Android 12 和房间寻呼现在会崩溃

Question

我已更新我的 Android 应用程序以面向 Android S，并被迫添加

api 'androidx.room:room-paging:2.4.0-beta01'

到我的 gradle 构建文件。

现在我的应用程序崩溃了

我哪里出错了？

修复方法是将分页 androidx.paging:paging-runtime-ktx 增加到 beta01

api 'androidx.room:room-ktx:2.4.0-beta01'
api 'androidx.room:room-runtime:2.4.0-beta01'
api 'androidx.room:room-paging:2.4.0-beta01'
api 'androidx.paging:paging-runtime-ktx:3.1.0-beta01'
kapt 'androidx.room:room-compiler:2.4.0-beta01'
