Remarks

Represents a phone call or connection to a remote endpoint that carries voice and/or video traffic.

Implementations create a custom subclass of Connection and return it to the framework as the return value of ConnectionService#onCreateIncomingConnection(PhoneAccountHandle, ConnectionRequest) or ConnectionService#onCreateOutgoingConnection(PhoneAccountHandle, ConnectionRequest). Implementations are then responsible for updating the state of the Connection, and must call #destroy() to signal to the framework that the Connection is no longer used and associated resources may be recovered.

Subclasses of Connection override the on* methods to provide the ConnectionService's implementation of calling functionality. The on* methods are called by Telecom to inform an instance of a Connection of actions specific to that Connection instance.

Basic call support requires overriding the following methods: #onAnswer(), #onDisconnect(), #onReject(), #onAbort()

Where a Connection has #CAPABILITY_SUPPORT_HOLD, the #onHold() and #onUnhold() methods should be overridden to provide hold support for the Connection.

Where a Connection supports a variation of video calling (e.g. the CAPABILITY_SUPPORTS_VT_* capability bits), #onAnswer(int) should be overridden to support answering a call as a video call.

Where a Connection has #PROPERTY_IS_EXTERNAL_CALL and #CAPABILITY_CAN_PULL_CALL, #onPullExternalCall() should be overridden to provide support for pulling the external call.

Where a Connection supports conference calling #onSeparate() should be overridden.

There are a number of other on* methods which a Connection can choose to implement, depending on whether it is concerned with the associated calls from Telecom. If, for example, call events from a InCallService are handled, #onCallEvent(String, Bundle) should be overridden. Another example is #onExtrasChanged(Bundle), which should be overridden if the Connection wishes to make use of extra information provided via the Call#putExtras(Bundle) and Call#removeExtras(String...) methods.
