"Android" common anomaly--android.view.windowleaked analysis and solutions

The problem is small, but I don't know if it's more troublesome. Exception information:

Copied directly from the project, the error code is show a progressdialog. Another case is that the finish activity also appears when the ProgressDialog is still displayed.

Cause Analysis:

Every activity in Android has a WindowManager form manager, as well as a dialog box built on top of an activity, and Popupwindow has a corresponding WindowManager form manager. Because dialogs and Popupwindown cannot be separated from activity , we go to finish () when a dialog or a Popupwindow is being displayed ( or Popupwindow), the window leaked exception is thrown, because this dialog (or Popupwindow) WindowManager has no one to associate with, So its form manager has leaked out.

Workaround:

Before closing (finish) an activity, make sure that the dialog or popupwindow attached to it is closed (dismiss).
