Example 1: In the following command sequence, the adb devices command starts the adb server, but the list of devices does not appear. Stop the adb server and enter the following commands in the order shown. For the avd name, providea valid avd name from your system. To get a list of avd names, type emulator -list-avds. Example 2: In the following command sequence, adb devices displays the list of devices because the adb server was started first.
To see the emulator in the adb devices output, stop the adb server, and then start it again after using the emulator command and before using the adb devices command, as follows:. If multiple devices are running, you must specify the target device when you issue the adb command. To specify the target, use the devices command to get the serial number of the target. Once you have the serial number, use the -s option with the adb commands to specify the serial number.
In the following example, the list of attached devices is obtained, and then the serial number of one of the devices is used to install the helloWorld. Note: If you issue a command without specifying a target device when multiple devices are available, adb generates an error. If you have multiple devices available, but only one is an emulator,use the -e option to send commands to the emulator. Likewise, if there are multipledevices but only one hardware device attached, use the -d option to send commands tothe hardware device.
You can use adb to install an APK on an emulator or connected devicewith the install command:. You must use the -t option with the install command when you install a test APK. For more information, see -t. Instead, Android Studio handles the packaging and installation of the app for you. You can use the forward command to set up arbitrary port forwarding, which forwards requests on a specific host port to a different port on a device. The following example sets up forwarding of host port to device port Use the pull and push commands to copy files toand from an device.
Unlike the install command,which only copies an APK file to a specific location, the pull and push commands let you copy arbitrary directories and files to any location in a device. In some cases, you might need to terminate the adb server process and then restart itto resolve the problem e.
To stop the adb server, use the adb kill-server command. You can then restart the server by issuing any other adb command. You can issue adb commands from a command line on your development machine or from a script. The usage is:. If there's only one emulator running or only one device connected, the adb command issent to that device by default.
You can use the shell command to issue device commands through adb, or to start aninteractive shell. To issue a single command use the shell command like this:. To start an interactive shell on a device use the shell command like this:.
Note: With Android Platform-Tools 23 and higher, adb handles arguments the same way that the ssh 1 command does. This change has fixed a lot of problems with command injection and makes it possible to now safely execute commands that contain shell metacharacters, such as adb install Let'sGo. But, this change means that the interpretation of any command that contains shell metacharacters has also changed.
For example, the adb shell setprop foo 'a b' command is now an error because the single quotes ' are swallowed by the local shell, and the device sees adb shell setprop foo a b. To make the command work, quote twice, once for the local shell and once for the remote shell, the same as you do with ssh 1.
For example, adb shell setprop foo 'a b'. Android provides most of the usual Unix command-line tools. For a list of available tools, usethe following command:. Help is available for most of the commands via the --help argument. Many of the shell commands are provided bytoybox.
