我是一名移动开发人员，现在我正在开发一个连接到 SAP 后端的 Android 应用程序。

我需要从 BAPI 创建 MBO 并从这些 BAPI 读取数据

我设法从 BAPI_FLIGHT_GETLIST BAPI 创建 MBO

我将代码生成为 Android 代码，并创建了从该 MBO 读取数据的活动

当我在 android 设备上运行应用程序时，我在这一行得到以下错误

app.registerApplication(TIMEOUT);

谁能帮我解决这个错误？

我不明白我做错了什么

主要活动：

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);
                    setContentView(R.layout.activity_main);
                    initializeApplication();
          }

private void initializeApplication() {

                      try {
                    // 1. App initialization
                       Application app = Application.getInstance();
                       app.setApplicationIdentifier("GetFlights");
                       app.setApplicationContext(MainActivity.this);
                       GetFlightsDB.setApplication(app);
                       GetFlightsDB.getSynchronizationProfile().setServerName(HOST);
                    // 2. Set connection properties
                       ConnectionProperties connProps = app.getConnectionProperties();
                       LoginCredentials loginCredentials = new LoginCredentials(USERNAME,PASSWORD);
                       connProps.setLoginCredentials(loginCredentials);
                       connProps.setServerName(HOST);
                       connProps.setPortNumber(PORT);
                      //3. App registration
                       if (app.getRegistrationStatus() != RegistrationStatus.REGISTERED) {
                           app.registerApplication(TIMEOUT); // ERROR HAPPENS HERE <-----------
                       } else {
                           app.startConnection(TIMEOUT);
                       }
                       //4. Sync data          
                       if (!GetFlightsDB.isSynchronized("default")) {
                                 GetFlightsDB.disableChangeLog();
                                 GetFlightsDB.synchronize(); // Initial Synchronize
                           SynchronizationGroup sg = GetFlightsDB.getSynchronizationGroup("default");
                           sg.setEnableSIS(true);
                           sg.save();
                           GetFlightsDB.synchronize();
                       }
                       GetFlightsDB.enableChangeLog();
                   }

             finally {
                       Log.v("Finally", "Finally");
                   }


          }

要连接到中继服务器，您必须提供 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
