[mono-android] how to open android gallery application in wallpaper mode

[michelw]

Hello,

When i've download a pic into the SDCARD, i want to tell android gallery 
application with this pic to set a new wallpaper, but i've no idea how 
to do this

anyone have a track, or keywords, to open the application with the 
image, the user can make his wallpaper

i search / try with a SendBroadcast(new Intent(Intent.SOMETHING, 
Android.Net.Uri.Parse("file://"...))); but it's not the good way (maybe)


thanks
