Question

I have an AlertDialog appear whenever I find that the device location has changed. This happens pretty much at anytime the application sees fit.

The problem is that if the dialog appears just before a new Activity is started the dialog disappears with the old Activity. Is there anyway to have the AlertDialog block new Intents? Or translate over to the new Activity (could I update the Context)?

I noticed that AlertDialogs don’t even handle the case where the device rotates, so my hope for this isn’t too high, but any input would help.

I would simply use a SharedPreference setting and check it whenever your potentially interruptive Activity starts.

Ex;

1. set shared preference value to 1
2. start dialogue
3. when finished, save the shared preference to 0
4. if activity starts and shared preference is 1, it interrupted so start an alert dialogue. if it is 0, move on.

Again, an AlertDialog is meant to attach itself to an activity, so you really can’t stop it from dieing, if your previous activity is pushed back or loses focus of the screen (ui thread basically put on hold!)

Hope you can fix your problem with this minor fixup.

To add what Daniel commented, Custom toasts can be awesome. They are, however, limited to about 3.5 seconds (I think)
