Creating client and server components to exchange binary messages between two android smartphones in the same wifi network

It is needed to create four projects: 1. One "library project" of a component that wait connection (server); 2. One "library project" of a component that makes the connection (client); 3. One working "example project" using the server component; 4. One working "example project" using the client component. - In addition to the projects, should be generated, for example and validation, two functional apks of the projects 3 and 4. - The communication must be in binary format, within the MQTT pattern ([login to view URL]). You should be able to specify which is the message number, and what is the binary content of the message. - The version of the Android SDK should be 19. - Both smartphones should be able to communicate when they are on the same wifi. - The server component must have a way to inform in what ip and port is waiting connection. - Both components must have an interface to send messages and an "Event Handler" to inform that it has received a message. - All projects must be developed in eclipse with android sdk, because they will be inserted into existing projects. - The components should be able to reconnect automatically in case of connection loss. - The code should be commented and well distributed. - A small manual explaining how to implement is required. - Delivery of all the code is mandatory.
