I would now like to build my own DTN application in order to send bundles from the phone and receive them on a computer connected on the same network.

I have looked at the code from DTNExampleApp and ShareBox.

When I use the DTNExampleApp, I keep getting the following messages in the logs (from DTNClient) :

- registration successful

- Session not available, need to register.

I tried to build my own app nevertheless but it is stuck on the DTNClient.getSession() blocking call.

This is what I did :

DTNClient client = new DTNClient();

Registration registration = new Registration("dtnsendapp");

client.initialize(this, registration);

EID destination = new SingletonEndpoint("dtn://receiver.dtn/dtnrecvapp");
Bundle b = new Bundle();
b.setDestination(destination);
b.setLifetime(3600L);
b.setReportto(SingletonEndpoint.ME);

Session s = client.getSession(); <-- program hangs here

String payload = "Hello World";

BundleID ret = s.send(b, payload.getBytes());

NB : I removed the Try, Catch to make the example as readable as possible.

My question is : How do I send a bundle using the provided API?

Thank you,

Jawad
