????????执行 Activity Manager (AM) 命令,比如启动 Activity、广播等。
????????执行 Package Manager (PM) 命令,如安装、卸载、禁用应用等。
????????将设备端口与本地端口进行转发,用于调试和测试。
????????模拟用户输入,比如触摸、按键操作等。
????????adb shell input tap x y
? ? ? ? 其中,x
和 y
是屏幕上的坐标值。
????????adb shell input swipe x1 y1 x2 y2 [duration(ms)]
????????其中?x1
、y1
是起始点坐标,x2
、y2
是终止点坐标,可选的 duration
参数表示滑动的时间(毫秒)。
????????adb shell input keyevent <key_code>
????????其中?key_code
是按键的代码,比如 KEYCODE_BACK 表示 返回键。
????????adb shell input text "android"
????????模拟文本输入,其中?android 是你想要输入的文本。
????????杀死adb服务:adb kill-server
????????重启adb服务:adb reconnect
????????netstat -aon|findstr "5037"
????????netstat -a -n -o |findstr "5037"
????????这两个命令都可以,且是Windows命令,它的作用是查找使用5037端口的进程ID。这个命令不适用于Linux、Mac或Unix系统,这就是为什么你看到“command not found”的错误。
????????5037 这是adb要的端口,有时候会被其他进程(程序)占用了(一般是会连接手机的软件),所以要查询是谁占用了,然后就可以Kill(停止)它;
????????根据上图然后输入taskkill /pid 12296/f (12296就是占用此端口的进程id),需要注意的是 ?有时候会查询到很多的进程(我一般选第一个,不行的话全部试一次),必须提示成功关闭才可行。
????????如果上面方法不行关闭电脑防火墙重启Android Studio试试。
