RemoteException in IntentService

I have the following code in my IntentService to send a Message to the registered clients:

for(Messenger client : clients) {
    client.send(aMessage);
}

According to the documentation of send(), this method can throw a RemoteException, a DeadObjectException specifically.

From the documentation of DeadObjectException:

The object you are calling has died, because its hosting process no longer exists.

If i understand correctly, this means that if my clients are all from the Service's process, (theoretically) this Exception will never be thrown.

Am i correct?

Thanks in advance.

Solution

  • Yes.
    But important to note that the whole purpose of Messenger is to communicate with different processes as mentioned in the official documentation:

    If you need your service to communicate with remote processes, then you can use a Messenger.

    If you need to communicate with your service in the same process I would recommend using local bound service.
