Hello

hi! the chat hour is nearly over -- do you have a quick question?

I do

I asked the question on the forum about getting notified about voicemail

ah, yes

the short is that I do have ADD_VOICEMAIL permission

I *think* it comes automatically because my app is the chosen default dialer for the phone

I haven't tested that yet, but regardless, I have the permission

(BTW, for anyone reading this transcript, this is a follow-on to https://community.commonsware.com/t/get-alert-o...)

my problem is that I have not messed with content providers in a long time

so when I did a quick and dirty "query" I got back null

null?

yeah, bupkiss

I can see an empty Cursor, but null?

well, I can't remember off the top of my head, I will try it again and follow up with details on the forum post above

but do you have any good resources that you would recommend for just KISS content provider stuff

just for me to do a sanity check that I actually do have access to that information (the voicemailcontract) ?

I have chapters on ContentProvider in *The Busy Coder's Guide to Android Development*

Ok, I will take a look and follow up on the forum

I don't cover VoicemailContract specifically, and looking at that class, they defined it oddly

thank you sir

how so?

no pre-defined Uri

they give you an authority string and nothing else

in particular, they do not provide any root paths

oh, wait

nevermind

it's on VoicemailContract.Voicemails

yeah, it shows authority / voicemails

ok, phew

:)

the annoying thing is that the broadcast should work too

in theory, at worst, a query() on VoicemailContract.Voicemails.CONTENT_URI should return an empty Cursor

are you sure your carrier supports all this?

well, the voicemailcontract is per the phone not the carrier right?

but the content is per the carrier

the phone itself has no voicemails

the voicemails are on some server at the carrier

so the question is, if my app is the default dialer does the carrier even notify the content provider

I would not expect the choice of dialer to affect how VoicemailContract's backing provider gets populated

yeah, that is what I was thinking too

that being said, other than "the carrier is involved", there isn't a lot of info on this, IIRC

kk, well, I don't want to keep you and I haven't done enough homework for a more intelligent question, so I will give it a shot....

for example, I haven't the foggiest notion how this works with unlocked phones, where the carrier is determined by the SIM card

yeah I am on Google Fi

well, there had better be good carrier support there :-)

one would think

:)

anyway, if you can post some code to that forum thread, I can take a peek at it

will do, thanks again

you're welcome!

that's the end of today's chat

the transcript will get posted to https://commonsware.com/office-hours/ shortly

and the next chat is Thursday at 8:30am US Eastern

have a pleasant evening!
