Work with DIalogs in fragments

In my application, I have an Activity and some fragments (Activity works like a Controller and Fragments - like views)

In some fragments I need to show AlertDialogs and ProgressDialogs, Activity can change the current fragment.

My problem: an activity can receive broadcast messages and C2DM notifications, and when I created AlertDialog, an Activity can change a fragment, but Dialog remains. Therefore, when the user clicks on some buttons, the application crashes.

DIalogFragments works like a simple dialog.

Disable the dialog manually or check if the fragment is active? Are there any built-in tools?

First of all, I could have missed something, without code, etc., but ...

Secondly: maybe you should not use dialogs? This seems to be a cumbersome user interface. Just use snippets for them? Although you say that you are using DialogFragments, you may already have thought of this and are using them as “regular” fragments already.

Third: Reject dialogs when the fragment that showed was deleted / hidden? Use the onStop () callback, for example, in a fragment or in a more central place where you might save the currently displayed fragment and decide to display a new one. Disable the dialog by calling wismiss in the Dialog object or Fragment or dismissDialog in the Activity.

See the rejection dialog: http://developer.android.com/guide/topics/ui/dialogs.html#DismissingADialog

You can still decline these dialog boxes. http://developer.android.com/reference/android/app/DialogFragment.htm
