My app is using the new VoicemailContract functionality in ICS to insert voicemails that show up in the stock call log. I've got it working perfectly, but I can't figure out how to control the new Voicemail notification that pops up when the new voicemails are added. The notifications seem to be controlled by the Phone app, and even if I manually update the voicemail's IS_READ attribute, the notification doesn't go away. In fact, I can delete the voicemail altogether, and the notification doesn't go away. The only way that it goes away is if that notification is clicked, or if I manually go into the call log and open one of the new voicemails.
Does anyone have any idea on how to control that programmatically from my app?
Unfortunately you can't. Status bar notifications can only be cleared by the app that placed them there. The phone app is the app that placed it there and this is why only that app is able to clear it.
I wish there was a way to do this myself, but currently, there is not :(
