[英]Is there a way to programmatically detect an ADB connection over WiFi?
I am developing an application that connects the client device to an adb server on a computer (over wifi) automatically.我正在开发一个应用程序,它自动将客户端设备连接到计算机上的 adb 服务器(通过 wifi)。 I am stuck on detecting whether it is successfully connected over wifi or not.我一直在检测它是否通过 wifi 成功连接。 Is there such thing as a java listener method that detects the connection to the device wirelessly?是否有 java 侦听器方法可以无线检测到设备的连接?

Thanks ahead of time!提前致谢!
I found a solution to this.我找到了解决方案。 Basically I make the application have TCP client functionality with selectable port.基本上我使应用程序具有可选择端口的 TCP 客户端功能。 I think you need to integrate ASyncTask for this to work.我认为您需要集成 ASyncTask 才能使其工作。 I know it needs to complete the 3-way-handshake so maybe something like broadcast, receive, acknowledge?我知道它需要完成 3 次握手,所以可能是广播、接收、确认之类的?
