4.0 New Features

Voice Android 4.0 has the following new features listed below:

1. Reconnecting State and Callbacks

Reconnecting State and Callbacks

RECONNECTING is now provided as a call state. A callback onReconnecting(...) corresponding to this state transition is emitted after the Call.Listener.onConnected(...) callback when a network change is detected and Call is already in CONNECTED state. If the call is in CONNECTINGor in RINGING state when network change happened, the SDK will continue attempting to connect and will not raise a callback. If a Call is reconnected after reconnectiong attempts, onReconnected(...) callback is raised and call state transitions to CONNECTED.

These changes are added as follows:

public class Call {

	public enum State {
		CONNECTING,
		RINGING, 
		CONNECTED,
		RECONNECTING, // State addition
		DISCONNECTED
	}

	public interface Listener {
		void onConnectFailure(@NonNull Call call, @NonNull CallException callException);
		void onRinging(@NonNull Call call); 
		void onConnected(@NonNull Call call);
		void onReconnecting(@NonNull Call call, @NonNull CallException callException); // Callback addition
		void onReconnected(@NonNull Call call); // Callback addition
		void onDisconnected(@NonNull Call call, @Nullable CallException callException);
	}
}
