最近有人发了一个WiFi调试的软件，实在话，这也不是个新鲜事了，电脑上也有插件支持，但是我总觉得不方便，感谢那位大兄弟加固了app，让我得以自己实现。

原理：root执行shell命令来控制adbd

开启：

setprop service.adb.tcp.port 你的端口 //例如setprop service.adb.tcp.port 5555
stop adbd
start adbd

关闭：

stop adbd

主要代码（shell执行，直接上别人的util）：

/**
 * CMD 命令行执行工具
 */public class CmdUtils {
    public static final String COMMAND_SU = "su"; // 表示获取root权限（APP必须已root）
    public static final String COMMAND_LINE_END = "\n";
    public static final String COMMAND_EXIT = "exit\n";

    /**
     * Android手机用Wifi连上电脑ADB调试
     * 须在手机终端输入如下命令
     * 此终端必须已经Root
     */
    public static Result execute(String[] commands) {
        //----------------- 待写：检查此手机是否已经Root-------------

        Runtime runtime = Runtime.getRuntime();

        Process process = null;
        DataOutputStream output = null; // 用于向终端进程输入命令
        BufferedReader successResult = null;
        BufferedReader errorResult = null;
        StringBuilder successMsg = null;
        StringBuilder errorMsg = null;

        try {
            process = runtime.exec(COMMAND_SU);
            output = new DataOutputStream(process.getOutputStream());
            for (String command : commands) {
                if (command == null) {
                    continue;
                }

                output.write(command.getBytes());
                output.writeBytes(COMMAND_LINE_END); // 输完一行命令要按回车
                output.flush();
            }

            output.writeBytes(COMMAND_EXIT);
            output.flush();
            process.waitFor(); // 当前线程等待，直到process线程执行结束

            successMsg = new StringBuilder();
            errorMsg = new StringBuilder();
            successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));
            errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));

            String s;
            while ((s = successResult.readLine()) != null) {
                successMsg.append(s).append("\n");
            }
            while ((s = errorResult.readLine()) != null) {
                errorMsg.append(s).append("\n");
            }


        } catch (Exception e) {
            e.printStackTrace();
        } finally { // 回收资源
            try {
                if (output != null) {
                    output.close();
                }
                if (successResult != null) {
                    successResult.close();
                }
                if (errorResult != null) {
                    errorResult.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
            }

            if (process != null) {
                process.destroy();
            }
        }
        return new Result(successMsg == null ? null : successMsg.toString()
                , errorMsg == null ? null : errorMsg.toString());
    }

    public static class Result {
        public String successMsg;
        public String errorMsg;

        public Result(String successMsg, String errorMsg) {
            super();
            this.successMsg = successMsg;
            this.errorMsg = errorMsg;
        }

    }
}
