Um, no, quite the opposite in fact.
My personal rule is to always push a complete RemoteViews update: the
text views, the image id's, the pending intents, the works. This way my
widget is always ready for an orientation or locale change, Launcher
being kicked out of memory, etc.
Splitting widget updates into separate steps, each with its own call to
updateAppWidget can lead to the widget not functioning, as there is only
one RV per widget maintained by the launcher. If that RV is not
complete, and one of the above events happens before you push a complete
one, then the widget won't be complete either (data or intents missing).
I'm not sure what you're trying to optimize by keeping a reference to
the old RV object. All it is, is just a list of pending actions (set
this view to "foo", this image to "bar", etc.) that's built up on your
application's side, sent over to the Launcher, and then replayed there.
Building the list should be fast, I don't see this as a bottleneck.

Oh wait. Do you mean that I have the thing like:
RemoteViews updateAppwidgetViews( ... ) {
RemoteViews remoteViews = new RemoteViews( ... );
// Set status message
remoteViews.setTextViewText( id, "refreshing" );
appWidgetManager.updateAppWidget( ..., remoteViews );
// Do the rest of the stuff
remoteViews( ..., ..., ... );
remoteViews( ..., ..., ... );
remoteViews( ..., ..., ... );
remoteViews( ..., ..., ... );
remoteViews( ..., ..., ... );
// Done
return remoteViews;
}
Sorry. Wasn't quite with you. That's not a bad idea. Cheers!
Nope. It's 2.1 or 2.2. It's the only way I could simulate making a
table on an appwidget... unless there's something a lot simpler that I
have missed...
