Interpretation of Android phonecall types

100 views Asked by At

The Android call logs give a type to each call, one of seven options: BLOCKED_TYPE, INCOMING_TYPE, MISSED_TYPE, OUTGOING_TYPE, REJECTED_TYPE, VOICEMAIL_TYPE, and ANSWERED_EXTERNALLY_TYPE.

My application is scanning through call logs, but I'm having difficulty interpreting this type information. The trouble is the options don't seem to be disjoint, i.e. a call I make that is rejected on the other end is both OUTGOING_TYPE and REJECTED_TYPE. A call that is incoming that I reject is INCOMING_TYPE and REJECTED_TYPE.

So it seems I'm missing something, and the docs themselves don't seem sufficient to make a proper interpretation.

My best guess is that BLOCKED_TYPE, MISSED_TYPE, REJECTED_TYPE, VOICEMAIL_TYPE, and ANSWERED_EXTERNALLY_TYPE all imply INCOMING_TYPE, and everything else is simply an unadorned OUTGOING_TYPE call. This is based on the assumption that the phone system does not provide meta-information on how the recipient of my call handled it, thus all the extra information about handling is coming from my phone itself and is about my actions, not theirs.

But I don't really know that. This is a very new area for me. Can someone please enlighten me as to what these call types really mean?
