Remember that widget RemoteViews updates are applied over a
potentially-cached layout. You should always set all values on each
update you send. For example, if the last update you passed only
updated a TextView, that single update could potentially be applied
over the top of a brand new layout (such as after an orientation
change).

Ok I think I figured it out. In certain cases when the widget is
clicked i updated the RemoteViews to hide some on screen controls/
views using setViewVisibility on the remoteview, however I did not re-
set the setImageURI. When the screen rotated the Image dissappeared.
However this is odd because I would expect the image to dissappear on
updating the RemoteView without the ImageURI even without rotating the
screen. But it would only dissappear after rotating. When I did not go
through the routine that hid the controls/ did not set the
setViewVisibility, the image did not dissappear on rotation.
I am curious as to what happens to the RemoteView on orientation
change and why sometimes it seems to retain the ImageURI and others it
loses it.
In any case I have my workaround.

I am building an appwidget that is displaying images from the sdcard.
I am investigating how to get the appwidget to perform correctly on an
orientation change. Currently I am setting the image on an image
button in the remoteview from a Bitmap I created in the program.
However it seems that when the orientation changes this bitmap is
destroyed and the image won't display unless I update the remoteview
of the appwidget after the orientation change.
What should I do so that when the appwidget is remade after
orientation change the image is able to be redisplayed automatically?
The only thing I can think of is using a setImageViewURI() to point
the remoteview to the image file itself using a URI (I am having
issues getting this to work correctly thus far).
It seems that none of my code is excecuted on this orientation change
as it is only rebuilding the remoteview. Is there an accepted practice
here? Thanks,
