When working with Android devices, developers often need to execute commands through the Android Debug Bridge (ADB). However, when multiple devices are connected, specifying the target device for ADB commands becomes essential. This guide will help you understand how to direct ADB commands to the correct device.
Identifying Connected Devices
First, list all connected devices using the following command:
adb devicesThis will display a list of devices attached to your computer. Each device is associated with a unique serial number or an IP address if connected over Wi-Fi.
Directing ADB Commands
To direct an ADB command to a specific device, use the -s flag followed by the device’s serial number:
adb -s SERIAL_NUMBER shellFor example, if the serial number is 7f1c864e, the command would be:
adb -s 7f1c864e shellIf you’re working with emulators and know the IP address and the port, the command format is similar:
adb -s IP_ADDRESS:PORT shellFor instance:
adb -s 192.168.232.2:5555 shellSpecial Cases
When only one emulator is running or only one USB device is connected, you can use the -e or -d flags, respectively:
- To target the only running emulator:
adb -e shelladb -d shellSetting the Environment Variable
Another approach is to set the ANDROID_SERIAL environment variable to the serial number of the desired device. This way, you won’t need to specify the serial number with each command.
On Windows, you can set the environment variable like this:
set ANDROID_SERIAL=7f1c864eOn UNIX-based systems, including Mac and Linux:
export ANDROID_SERIAL=7f1c864eIntegrating with Repeato
