Request for Service

Request for Service

Once your service interface object is ready (IWeather.Stub.asInterface(binder)), you can start calling methods on it as you need to. In fact, if you disabled some widgets awaiting the connection, now is a fine time to re-enable them.

However, you will want to trap two exceptions. One is DeadObjectException — if this is raised, your service connection terminated unexpectedly. In this case, you should unwind your use of the service, perhaps by calling onServiceDisconnected() manually, as shown previously. The other is RemoteException, which is a more general-purpose exception indicating a cross-process communications problem. Again, you should probably cease your use of the service.
