java - 有没有办法通过 WiFi 以编程方式检测 ADB 连接？

Question

我正在开发一个应用程序，可以自动将客户端设备连接到计算机上的 adb 服务器(通过 wifi)。我坚持检测它是否通过 wifi 成功连接。是否有 java 监听器方法可以无线检测与设备的连接？

主要 Activity .java

    public class MainActivity extends AppCompatActivity {

    private Thread thread;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        // Check for Wireless connection


        // Check for USB connection
        thread = new Thread() {
            @Override
            public void run() {
                try {
                    while (!thread.isInterrupted()) {
                        Thread.sleep(100);
                        runOnUiThread(new Runnable() {
                            @Override
                            public void run() {
                                if(usbDebuggingConnected()){
                                    WifiManager manager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);
                                    assert manager != null;
                                    WifiInfo info = manager.getConnectionInfo();
                                    String address = info.getMacAddress();
                                    TextView t = findViewById(R.id.usb_connection);
                                    t.setText("Connected with the address - " + address);
                                    t.setTextColor(getResources().getColor(R.color.green));
                                } else {
                                    TextView t = findViewById(R.id.usb_connection);
                                    t.setText("USB Debugging Disconnected");
                                    t.setTextColor(getResources().getColor(R.color.red));
                                }
                            }
                        });
                    }
                } catch (InterruptedException ignored) {
                }
            }
        };
        thread.start();
    }

    public boolean usbDebuggingConnected() {
        Intent intent = registerReceiver(null, new IntentFilter("android.hardware.usb.action.USB_STATE"));
        assert intent != null;
        return Objects.requireNonNull(intent.getExtras()).getBoolean("connected");
    }

我找到了解决办法。基本上我使应用程序具有带有可选端口的 TCP 客户端功能。我认为您需要集成 ASyncTask 才能使其工作。我知道它需要完成 3 次握手，所以可能需要广播、接收、确认之类的东西？
