android - IllegalArgumentException View not attached to window manager

Question

请问下这是什么bug？？？

Answer 1

It seems that the activity was killed and the dialog method was called again

Answer 2

Dialog cannot exist independently. It must be attached to the activity, that is, the window. If your window is destroyed, an error will be reported. But it seems that your error is not that the activity was destroyed, but that you used the wrong context to construct the dialog. Check this parameter.
