Code snippet of issue

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/536.5 (KHTML,

The issue I've now been struggling with seems to be getting worse, I
dynamically create an ImageButton - set it's bitmap if applicable and allow
user to click ImageButton to re-capture image if need be by using the Camera

If I click the ImageButton very first time the Camera Intent launches perfectly
and I can take the picture and OnActivityResult I set the ImageButton URI to
the Image just taken. The ImageButton gets disposed of after I click a "Next"
button which performs some more dynamic screen layout stuff. Later on the
ImageButton gets re-created again in the same Activity/Screen and when I click
it again, the  Camera Intent opens however the application bombs out. No
seemingly useful debug output is presented to help trace where I'm going
wrong... If I am... This was working perfectly prior to the latest upgrade to

To make matters even more confusing I uninstalled 4.2.2 and reverted to 4.0.1 -
 Same thing occurred -  I then re-installed 4.2.2 again. This just seemed to
make the issue happen more frequently and even less easy to understand why; as
it would then happen randomly on the first time the ImageButton was created and
I clicked on it. I've googled all I can, tried only creating the ImageButton
once and keeping it in memory I've tried removing the Event Handler after the
ImageButton is used just incase it was triggering the event twice. I've tried
setting the Activity flag of the Camera Intent to "SingleTop" & "NoHistory" to
no avail. I've tried everything I can think of :-)

I don't know if this is something to do with my implementation or something to
do with MonoDroid, the fact that it was working before and now all of a sudden
not, leads me to believe it's your fault :-) I'd be happy to here it's mine and
how to remedy!

Tried this on Sony Xperia Arc, Samsung Galaxy Y, Samsung Galaxy Note. All same

Reproducible: Always

Steps to Reproduce:
1. Dynamically create ImageButton.
2. Draw Bitmap to ImageButton from sqlLite if exists
3. Re-take photo using Camera Intent
4. New image to replace old one on ImageButton
5. Click another button which clears the screen and draws something else,
button,radio's etc...
6. Click that other button again to recreate ImageButton use same EventHandler
as before.
7. Draw Bitmap to ImageButton from sqlLite if exists
8. Click the ImageButton
9. Camera Intent opens (sometimes can take image then app crashes - rarely)
10. VS 2012 debugging disconnects and app exists/crashes
Actual Results:  
VS 2012 debugging disconnects and app exists/crashes

Expected Results:  
VS 2012 debugging remains and app doesn't crash.
