Known issues

If you close the Dialog/Activity without the Tooltip is closed, there may be the exception java.lang.IllegalArgumentException: Could not lock surface. This error occurs because the animation continue for a while after closing the Dialog/Activity. (This error does not impact the execution of the app)
If you call tooltip.show() after Activity/Dialog is closed, there may be the exception android.view.WindowLeaked: Activity has leaked window android.widget.PopupWindow$PopupViewContainer that was originally added here. Read more. (This error does not impact the execution of the app)
From API 24, Android has changed the behavior of PopupWindow in relation to the setClippingEnabled property, which causes the Popup to be cut off. Read more.
