Public methods
onAvailableSaisUpdated
public void onAvailableSaisUpdated (List<Integer> currentSais, List<List<Integer>> availableSais)
Indicates that the list of currently available SAIs has been updated. The app may use this information to filter the list of group calls when displaying available group calls to the user by matching the SAIs with a list of group calls separately negotiated with the carrier. The app may also report the aggregate list of SAIs to the group call application server so that a network entity can determine when, and where to activate the broadcast of particular group calls.
| Parameters | |
|---|---|
currentSais |
List: The available SAIs on the current cell.
This value cannot be null. |
availableSais |
List: A list of lists of available SAIS in neighboring cells, where each list
contains the available SAIs in an individual cell.
This value cannot be null. |
onError
public void onError (int errorCode,
String message)Called by the middleware when it has detected an error condition. The possible error codes
are listed in MbmsErrors.
| Parameters | |
|---|---|
errorCode |
int: The error code.
Value is MbmsErrors.ERROR_NO_UNIQUE_MIDDLEWARE, MbmsErrors.ERROR_MIDDLEWARE_LOST, MbmsErrors.ERROR_MIDDLEWARE_NOT_BOUND, MbmsErrors.InitializationErrors.ERROR_APP_PERMISSIONS_NOT_GRANTED, MbmsErrors.InitializationErrors.ERROR_DUPLICATE_INITIALIZE, MbmsErrors.InitializationErrors.ERROR_UNABLE_TO_INITIALIZE, MbmsErrors.GeneralErrors.ERROR_MIDDLEWARE_NOT_YET_READY, MbmsErrors.GeneralErrors.ERROR_OUT_OF_MEMORY, MbmsErrors.GeneralErrors.ERROR_MIDDLEWARE_TEMPORARILY_UNAVAILABLE, MbmsErrors.GeneralErrors.ERROR_IN_E911, MbmsErrors.GeneralErrors.ERROR_NOT_CONNECTED_TO_HOME_CARRIER_LTE, MbmsErrors.GeneralErrors.ERROR_UNABLE_TO_READ_SIM, or MbmsErrors.GeneralErrors.ERROR_CARRIER_CHANGE_NOT_ALLOWED |
message |
String: A human-readable message generated by the middleware for debugging purposes.
This value may be null. |
onMiddlewareReady
public void onMiddlewareReady ()
Called to indicate that the middleware has been initialized and is ready.
Before this method is called, calling any method on an instance of
MbmsGroupCallSession will result in an IllegalStateException or an error
delivered via onError(int, java.lang.String) with error code
MbmsErrors.GeneralErrors.ERROR_MIDDLEWARE_NOT_YET_READY.
onServiceInterfaceAvailable
public void onServiceInterfaceAvailable (String interfaceName, int index)
Called soon after the app calls MbmsGroupCallSession.create. The information supplied
via this callback may be used to establish a data-link interface with the modem.
In order to establish the data-link interface, the multicast IP and port must be obtained
out-of-band from the carrier. A MulticastSocket may then be constructed
using a NetworkInterface with the name and interface supplied by this
callback.
| Parameters | |
|---|---|
interfaceName |
String: The interface name for the data link.
This value cannot be null. |
index |
int: The index for the data link. |
