There are two issues here.
One is, what happens to widgets when the application package is updated
(during development or via a Market update).
The way it's supposed to work is that all widgets get a chance to update
via onUpdate. In practice, I've seen onUpdate get called, but the widget
not reflecting the update, and stopping to function (not responding to
clicks, the UI getting reset, etc.) on one device from a major company,
out of the three I have.
So for updates - there no need to instruct the users to always recreate
your widgets, but it can be necessary on some devices.
Two is debugging. I haven't seen this - but I'd check the DDMS
perspective to make sure that the process actually connects to the
Eclipse debugger (there is a bright green "bug" icon next to the process).
Other than that, widgets are broadcast receivers, and as such, give you
a very short time window once you've hit a breakpoint. If you spend more
than a few seconds on a breakpoint that is triggered by onReceive, the
process will get killed by Android, and lose the debugger connection.

Hi,
I have an application that includes a couple of widgets.
During development, I place the widgets on the homescreen of the
emulator and start developing.
When I'm working in Eclipse, and I'm pushing a new version of my app
to the emulator, I sometimes have the impression that the widgets are
becoming "stale".
Breakpoints that were on the widgets code don't appear to be active
anymore (don't have the "v" marker), and the debugger doesn't suspend
on them. When I remove the widget and I place it on the homescreen
again, the breakpoint becomes active and the debugger starts
suspending again.
Is that something you need to take into account when developing
widgets ? Also, when I push a new version of my app on the market, and
my users already had the widgets on the homescreen, are they advised
to "refresh" them by removing / adding them again ?
Regards,
Davy
