Android adb download

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:. For more information about emulator command-line options, see Using Command Line Parameters.

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 multiple devices but only one hardware device attached, use the -d option to send commands to the hardware device.

You can use adb to install an APK on an emulator or connected device with 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 to and 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 it to 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 is sent to that device by default. You can use the shell command to issue device commands through adb, or to start an interactive 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. 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, use the following command:. Help is available for most of the commands via the --help argument. Many of the shell commands are provided by toybox. General help applicable to all toybox commands is available via toybox --help.

See also Logcat Command-Line Tool which is useful for monitoring the system log. Within an adb shell, you can issue commands with the activity manager am tool to perform various system actions, such as start an activity, force-stop a process, broadcast an intent, modify the device screen properties, and more. While in a shell, the syntax is:. You can also issue an activity manager command directly from adb without entering a remote shell.

See the Specification for intent arguments. Options are: -D : Enable debugging. Prior to each repeat, the top activity will be finished. This command kills only processes that are safe to kill and that will not impact the user experience. Use with [-e perf true] to generate raw output for performance measurements. Required for test runners. Options are: -w : Wait for debugger when app starts. This command is helpful for testing your app across different screen sizes by mimicking a small screen resolution using a device with a large screen, and vice versa.

Example: am display-size x display-density dpi Override device display density. This command is helpful for testing your app across different screen densities on high-density screen environment using a low density screen, and vice versa. Example: am display-density to-uri intent Print the given intent specification as a URI. Specification for intent arguments For activity manager commands that take an intent argument, you can specify the intent with the following options:. Within an adb shell, you can issue commands with the package manager pm tool to perform actions and queries on app packages installed on the device.

You can also issue a package manager command directly from adb without entering a remote shell. Options: -f : See their associated file. Options: -g : Organize by group. Options: -f : List the APK file for the test package. Options: -r : Reinstall an existing app, keeping its data. This feature is only supported on certain devices. This option forces adb to use the feature or fail if it is not supported with verbose information on why it failed. Options: -k : Keep the data and cache directories around after package removal.

On devices running Android 6. On devices running Android 5. Location values: 0 : Auto: Let system decide the best location. Note: This is only intended for debugging; using this can cause apps to break and other undesireable behavior.

To help you develop and test your device management or other enterprise apps, you can issue commands to the device policy manager dpm tool. Use the tool to control the active admin app or change a policy's status data on the device. You can also issue a device policy manager command directly from adb without entering a remote shell:.

You can also pass --user current to select the current user. The app must declare android:testOnly in the manifest. This command also removes device and profile owners. This is useful to avoid the device's scheduling restrictions when developing apps that manage freeze-periods.

See Manage system updates. Supported on devices running Android 9. This command is rate-limited. The screencap command is a shell utility for taking a screenshot of a device display. The utility records screen activity to an MPEG-4 file. You can use this file to create promotional or training videos or for debugging and testing. To begin recording your device screen, run the screenrecord command to record the video. Then, run the pull command to download the video from the device to the host computer.

The utility records at the native display resolution and orientation by default, with a maximum length of three minutes. Table 5. Starting in Android 7.

You might want to examine the collected profiles to understand which methods are determined to be frequently executed and which classes are used during app startup. If you test your app across multiple test devices, it may be useful to reset your device between tests, for example, to remove user data and reset the test environment.

You can perform a factory reset of a test device running Android 10 API level 29 or higher using the testharness adb shell command, as shown below. When restoring the device using testharness , the device automatically backs up the RSA key that allows debugging through the current workstation in a persistent location.

That is, after the device is reset, the workstation can continue to debug and issue adb commands to the device without manually registering a new key. Additionally, to help make it easier and more secure to keep testing your app, using the testharness to restore a device also changes the following device settings:. If you app needs to detect and adapt to the default settings of the testharness command, you can use the ActivityManager.

It includes commands such as. You can also execute SQLite commands from the command line, as shown below. For more information, see the sqlite3 command line documentation.
