Downloading adb from android

It locates emulators by scanning odd-numbered ports in the range to , the range used by the first 16 emulators. Where the server finds an adb daemon adbd , it sets up a connection to that port.

Note that each emulator uses a pair of sequential ports — an even-numbered port for console connections and an odd-numbered port for adb connections. For example:. Emulator 1, console: Emulator 1, adb: Emulator 2, console: Emulator 2, adb: and so on As shown, the emulator connected to adb on port is the same as the emulator whose console listens on port Once the server has set up connections to all devices, you can use adb commands to access those devices.

Because the server manages connections to devices and handles commands from multiple adb clients, you can control any device from any client or from a script.

On Android 4. Return to the previous screen to find Developer options at the bottom. You can now connect your device with USB. If connected, you'll see the device name listed as a "device. Note: When you connect a device running Android 4. This security mechanism protects user devices because it ensures that USB debugging and other adb commands cannot be executed unless you're able to unlock the device and acknowledge the dialog.

Android 11 and higher support deploying and debugging your app wirelessly from your workstation using Android Debug Bridge adb. For example, you can deploy your debuggable app to multiple remote devices without physically connecting your device via USB.

This eliminates the need to deal with common USB connection issues, such as driver installation. To use wireless debugging, you need to pair your device to your workstation using a pairing code. Your workstation and device must be connected to the same wireless network. 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. If you see none of the above options you may have to select Show All Devices at the top of the list and then click the Next button to get a complete list of device drivers installed on your system.

Please be patient when selecting Show All Devices , it can take a few minutes to populate the list. If the procedure above was successful, you should now see something similar to the following when you inspect the Device Manager with your Android test device attached via USB the precise name of this 'interface' under the Android Device may vary as a function of the ADB debug driver you used, but it should say something about 'ADB' :.

There is nothing wrong with your Android device or your system, if this happens; it simply is required with some Android devices. Now, try the Chrome desktop browser test described on this page to confirm that your Windows workstation can communicate with your Android device. Do not follow the third step in that article, use the process outlined above to finish the process! You may need to go through this process again each time you connect a new Android device especially devices from a different manufacturer.

In that case, if you have previously installed the Intel or Google or Samsung or some other Android USB debug driver, you can select that driver from the available list of drivers and it will work with your new device. To do that, follow the steps below:. On the other hand, if you see the name of your Android device, then it means that you already have the ADB driver on your computer.

Of course, before you can add the ADB driver to your PC, you have to get the installation file first. Download the installation file from the official website. Here are the steps:. In this article, we are going to use Google Nexus 7 because the steps are quite similar for all other Android devices. You just need to follow the first four steps, then select Uninstall Device.
