SUP：通过中继服务器连接Android应用SAP-SUP

Question

I am a mobile developer and now im working on an Android app that connects to SAP backend.

i need to create MBOs from BAPIs and read data from those BAPIs

I managed to create the MBOs from BAPI_FLIGHT_GETLIST BAPI

i generated the code as Android code and i created the activity to read the data from this MBO

when i run the application on android device i get below error in this line

app.registerApplication(TIMEOUT);

can anyone help me with this error ?

i don't understand what am i doing wrong

MainActivity:

private static final int REQUEST_DETAIL = 99;
          private static String USERNAME = "*********";
          private static String PASSWORD = "**********";
          private static String HOST = "************";
          private static int PORT = 5001; // 2480
          private static int sync_port = 2480;
          private static int TIMEOUT = 600;
private GetFlightsListAdapter adapter;


@Override
          protected void onCreate(Bundle savedInstanceState) {
                    super.onCreate(savedInstanceState);

                    initializeApplication();
          }

                      try {
                    // 1. App initialization

                       app.setApplicationIdentifier("GetFlights");
                       app.setApplicationContext(MainActivity.this);
                       GetFlightsDB.setApplication(app);

To Connect to relay server you have to provide the Farm id.

ConnectionProperties connProps = app.getConnectionProperties();
LoginCredentials loginCredentials = new    LoginCredentials(USERNAME,PASSWORD);
connProps.setLoginCredentials(loginCredentials);
connProps.setServerName(HOST);
connProps.setPortNumber(POST); port for relay server is 80
connProps.setUrlSuffix("/ias_relay_server/client/rs_client.dll/%cid%/tm");
connProps.setFarmId(FARMID); //provide MBS farm Id for registration. And sync will be      different
