Android Debug Bridge Command

1 . 多部手机的问题
开发时电脑连着测试机和自己的手机，输入 adb 命令 ➜adb get-serialno 会报错

➜adb get-serialno 
error: more than one device/emulator

这时可以 需要 用 adb devices 查看有哪些设备，最后接入的设备在最前面。

➜adb devices
List of devices attached
375013eb device
TA004031ND device

要在某部手机上执行命令 需要指定 设备号 比如

➜ adb -s 375013eb  get-serialno
375013eb

我有时候分不清设备的序列号，或者会连其他人的手机进行操作，就写了下面的命令，在最后接入的手机的设备执行命令。

➜ adb -s `adb devices |sed -n "2,1p" |awk '{print $1}'` get-serialno
375013eb

也是输出 375013eb，把另外一部手机拔了再插，输出 TA004031ND

2 . 显示最前面的界面是哪一个 activity
有时产品或者运营会拿着手机来问某个界面的事情，如果是新接触一个项目，并不能记得住每一个界面对应哪个 activity 。其实接手很久了也不一定记得住,哈哈 。通过代码去找太费时间，而且不同的账号可能会跳不同的Activity ，逻辑太多，也容易找错。用下面的命令就可以直接找到当前界面对应哪一个 activity 了。
adb shell dumpsys activity activities | sed -En -e '/Running activities/,/Run #0/p'

➜ adb -s `adb devices |sed -n "2,1p" |awk  '{print $1}'`  shell dumpsys activity activities | sed -En -e '/Running activities/,/Run #0/p'

Running activities (most recent first):
      TaskRecord{d96bc0b #10580 A=com.medium.reader U=0 sz=2}
        Run #5: ActivityRecord{b7f4a69 u0 com.medium.reader/com.medium.android.donkey.read.ReadPostActivity t10580}
