问题 I am implementing dark mode on my app, and I am facing a peculiar(to me) problem. Below is the logcat of the crash, which I am facing only in dark mode , no error/warning in Light/Default (I am in SDK<=29 , so my default is battery saver) mode.

问题 I want to design a TextView and EditText with round corner. There is one straight forward solution for this. Using custom shape background.
