Android : Dialog: should I hide or dismiss

Question

I'm playing around with Dialog to create some quick views in my app (like login enter name etc)

and I'm wandering what is better: hide or dismiss.

I know what they both do but I keep wandering if it is better to just hide a Dialog and show it again when I need or to dismiss it and recreate it.

my Dialogs are small and are actually static in my code so as such I don't hold tons of instances.

So can somebody give me the pros and cons of using hide over dismiss.

Answer 1

Using hide() could cause a Leaked Window error.

If you choose to use hide() and you exit your application using finish(), this will cause an error message (seen here) about a window being leaked.

So, either dismiss() your dialogs properly before calling finish() or just use dismiss() instead of hide().

Answer 2

It depends on how many time your need it, and if it is expensive to create it. If it is not too expensive to create it, I would personally prefer to dismiss it, to have a "cleaner environment". But if you're not using hundreds of dialogs, I don't think this really matters.
