* The TransactionService of the MMS Client is responsible for handling requests
* to initiate client-transactions sent from:
* <ul>
* <li>The Proxy-Relay (Through Push messages)</li>
* <li>The composer/viewer activities of the MMS Client (Through intents)</li>
* </ul>
* The TransactionService runs locally in the same process as the application.
* It contains a HandlerThread to which messages are posted from the
* intent-receivers of this application.
* <p/>
* <b>IMPORTANT</b>: This is currently the only instance in the system in
* which simultaneous connectivity to both the mobile data network and
* a Wi-Fi network is allowed. This makes the code for handling network
* connectivity somewhat different than it is in other applications. In
* particular, we want to be able to send or receive MMS messages when
* a Wi-Fi connection is active (which implies that there is no connection
* to the mobile data network). This has two main consequences:
* <ul>
* <li>Testing for current network connectivity ({@link android.net.NetworkInfo#isConnected()} is
* not sufficient. Instead, the correct test is for network availability
* ({@link android.net.NetworkInfo#isAvailable()}).</li>
* <li>If the mobile data network is not in the connected state, but it is available,
* we must initiate setup of the mobile data connection, and defer handling
* the MMS transaction until the connection is established.</li>
* </ul>
