Memory leak

[alexeyr15]

I use a snackbar with the custom duration 10 sec. If a user presses Back when a snackbar is showing, then the activity is finished but it cannot be garbage collected because there is a strong reference to it from the handler queue (due to postDelayed() method call):

Handler -> mDismissRunnable -> Snackbar (outer class) -> Activity

I think it is needed to call removeCallbacks(mDismissRunnable); from onDetachedFromWindow(), for example.

Thanks for reporting this. As a workaround, could you dismiss all Snackbars on your onPause() method?

I don't think that dismissing a snackbar eliminates the memory leak. As I see from the source code removeCallbacks(mDismissRunnable) is only called when swiping a snackbar. So if I would call dismiss() in onPause() a reference to the activity is still exists and will be only destroyed when Runnable in postDelayed() is fired.

I see. Will upload a version shortly with the call in onDetachedFromWindow() as you suggested. It's probably the best place to remove the callbacks
