当前回答

在看到“不止一个设备”错误后,我发现了这个问题,2个离线电话显示:

C:\Program Files (x86)\Android\android-sdk\android-tools>adb devices
List of devices attached
SH436WM01785    offline
SH436WM01785    offline
SH436WM01785    sideload

如果您只连接了一台设备,请执行以下命令清除离线连接:

adb kill-server
adb devices

其他回答

在所有连接的设备上运行adb命令

创建一个bash (adb+)

adb devices | while read line
do
if [ ! "$line" = "" ] && [ `echo $line | awk '{print $2}'` = "device" ]
then
    device=`echo $line | awk '{print $1}'`
    echo "$device $@ ..."
    adb -s $device $@
fi

完成 使用它

adb+//+命令

你可以使用它来连接你的特定设备:

   * adb devices
  --------------
    List of devices attached
    9f91cc67    offline
    emulator-5558   device

我想连接到第一个设备“9f91cc67”

* adb -s 9f91cc67 tcpip 8080
---------------------------
restarting in TCP mode port: 8080

then

* adb -s 9f91cc67 connect 192.168.1.44:8080
----------------------------------------
connected to 192.168.1.44:8080

也许这能帮到别人

下面是我为自己编写的shell脚本:

#! /bin/sh

for device in `adb devices | awk '{print $1}'`; do
  if [ ! "$device" = "" ] && [ ! "$device" = "List" ]
  then
    echo " "
    echo "adb -s $device $@"
    echo "------------------------------------------------------"
    adb -s $device $@
  fi
done

当有多个设备连接时,这个要点将为你显示菜单做大部分工作:

$ adb $(android-select-device) shell
1) 02783201431feeee device 3) emulator-5554
2) 3832380FA5F30000 device 4) emulator-5556
Select the device to use, <Q> to quit:

为了避免输入,您可以创建一个别名,其中包括此处解释的设备选择。

对我的测试有效的方法:

Ubuntu bash终端:

$ adb devices
List of devices attached 
646269f0    device
8a928c2 device
$ export ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL
646269f0
$ adb reboot bootloader

Windows命令提示符:

$ adb devices
List of devices attached 
646269f0    device
8a928c2 device
$ set ANDROID_SERIAL=646269f0
$ echo $ANDROID_SERIAL$
646269f0
$ adb reboot bootloader

这使您可以使用正常的命令和脚本,就好像只有ANDROID_SERIAL设备附加。

或者,您可以每次都提到设备序列号。

$ adb -s 646269f0 shell
