如何在 Android Studio 上使用 Mikrotik API

Question

我正在尝试在 android 中使用 mikrotik api Java，但是当我下载它并将其添加到 android studio 项目并在应用程序中使用它时被迫关闭！

这是我的代码：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    final String[] string_array = getResources().getStringArray(R.array.ip_venue);
    spinner2 = findViewById(R.id.list_venue);
    spinner2.setOnItemSelectedListener(new OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<?> arg0, View view, int position, long id12) {
                String Host1 = String.valueOf(string_array[arg0.getSelectedItemPosition()]);
            ApiConnection con = null; // connect to router
            try {
                con = ApiConnection.connect(SocketFactory.getDefault(), Host1, PORT, 2000);
            } catch (MikrotikApiException e) {
                e.printStackTrace();
            }
            try {
                con.login(USERNAME,PASSWORD); // log in to router
            } catch (MikrotikApiException e) {
                e.printStackTrace();
            }
            try {
                con.execute("/system/reboot"); // execute a command
            } catch (MikrotikApiException e) {
                e.printStackTrace();
            }
            try {
                con.close(); // disconnect from router
            } catch (ApiConnectionException e) {
                e.printStackTrace();
            }
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
        }
    });
}

我收到这条消息：

已与目标 VM 断开连接，地址：'localhost:8620'，传输：'socket'

我在这里做错了什么？我不是 Android 开发人员，但正在尝试构建对我工作的公司有用的东西。

在 android 中，您不能运行在主线程上执行与网络相关的操作 - 您需要在不同的线程上运行它们，例如：

Thread yourThread = new Thread(new Runnable() {

@Override
public void run() {
    try  {
        //Put your code in here
    } catch (Exception e) {
        e.printStackTrace();
    }
  }
});

yourThread .start();
