Attributes

Remarks

Sends an event associated with this Connection with associated event extras to the InCallService.

Connection events are used to communicate point in time information from a ConnectionService to a InCallService implementations. An example of a custom connection event includes notifying the UI when a WIFI call has been handed over to LTE, which the InCall UI might use to inform the user that billing charges may apply. The Android Telephony framework will send the #EVENT_CALL_MERGE_FAILED connection event when a call to Call#mergeConference() has failed to complete successfully. A connection event could also be used to trigger UI in the InCallService which prompts the user to make a choice (e.g. whether they want to incur roaming costs for making a call), which is communicated back via Call#sendCallEvent(String, Bundle).

Events are exposed to InCallService implementations via Call.Callback#onConnectionEvent(Call, String, Bundle).

No assumptions should be made as to how an In-Call UI or service will handle these events. The ConnectionService must assume that the In-Call UI could even chose to ignore some events altogether.

Events should be fully qualified (e.g. com.example.event.MY_EVENT) to avoid conflicts between ConnectionService implementations. Further, custom ConnectionService implementations shall not re-purpose events in the android.* namespace, nor shall they define new event types in this namespace. When defining a custom event type, ensure the contents of the extras Bundle is clearly defined. Extra keys for this bundle should be named similar to the event type (e.g. com.example.extra.MY_EXTRA).

When defining events and the associated extras, it is important to keep their behavior consistent when the associated ConnectionService is updated. Support for deprecated events/extras should me maintained to ensure backwards compatibility with older InCallService implementations which were built to support the older behavior.
