Solution of android.view.windowleft in Android

Literally, window leaked means that a form leaks, which is what we often call a memory leak. Why does the form leak?

Causes:

We know that every Android activity has a WindowManager form manager. Similarly, the dialog box and popupwindow built on an activity also have a corresponding WindowManager form manager. Because the dialog box and popupwindow cannot exist separately from the activity, when a dialog or popupwindow is displaying, we finish() the activity hosting the dialog (or popupwindow), we will throw the window left exception, because no one can attach to the WindowManager of this dialog (or popupwindow), So its form manager has leaked.

resolvent:

Before closing an activity, make sure that the dialog or popupwindow attached to it has been closed.
