android adb常见问题的解决方法！

** adb的常见问题
    adb：android debug bridge，用于连接模拟器/手机与PC端软件（例如：eclipse或者xx手机助手）

    adb devices -> 检查连接到的模拟器/手机

    adb kill-server -> 停止adb
    adb start-server -> 启动adb

    如果执行adb start-server没有反应（通常是因为5037端口被占用），那么打开Windows的任务管理器，终止adb.exe进程，并重新执行adb start-server

    如果是未知的进程占用了5037端口，则使用以下第1条命令找到进程的PID，然后再终止该进程，最后重新执行adb start-server
    netstat -ano -> 查询本机的端口占用情况，找到5037端口listening的PID;
 tasklist /fi "pid eq ???" -> 根据PID终止某个进程                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                               ‘
