Android sdk adb download

Thanks to external contributor Spencer Low! Fix a file descriptor double-close that can occur, resulting in connections being closed when an adb connect happens simultaneously. Fix adb forward --list when used with more than one device connected. Sort output of adb devices by connection type and device serial. Increase the socket listen backlog to allow for more simulataneous adb commands. Improve error output for adb connect. Clean up help output.

Add product. Avoid bricking new devices when using a too-old version of fastboot by allowing factory image packages to require support for specific partitions. In this release, the old non-libusb implementation remains the default. Introduction 1. Accepting this License Agreement 2.

You should see a device in the list. You can also search XDA Developers for driver downloads without the extra software. This will work with some phones including Nexus devices.

The process is a bit different on Windows 7 and 10, so check out our full guide to editing your System PATH for the steps required to do this.

It includes tools that interface with the Android platform, such as adb, fastboot, and systrace. These tools are required for Android app development. To test whether ADB is working properly, connect your Android device to your computer using a USB cable and run the following command: You should see a device in the list. On the Driver tab, click Update Driver. To connect to your device, follow these steps:. Before issuing adb commands, it is helpful to know what device instances are connected to the adb server.

You can generate a list of attached devices using the devices command. The following example shows the devices command and its output. There are three devices running. The first two lines in the list are emulators, and the third line is a hardware device that is attached to the computer. The adb devices command has a corner-case command sequence that causes running emulator s to not show up in the adb devices output even though the emulator s are visible on your desktop.

This happens when all of the following conditions are true:. One way to avoid this situation is to let the emulator choose its own ports, and don't run more than 16 emulators at once.

Another way is to always start the adb server before you use the emulator command, as explained in the following examples. 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, provide a 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:. 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.
