Download adb and fastboot for android

The adb command facilitates a variety of device actions, such as installing and debugging apps, and it provides access to a Unix shell that you can use to run a variety of commands on a device. It is a client-server program that includes three components:. For information on connecting a device for use over ADB, including how to use the Connection Assistant to troubleshoot common problems, see Run apps on a hardware device. When you start an adb client, the client first checks whether there is an adb server process already running.

If there isn't, it starts the server process. When the server starts, it binds to local TCP port and listens for commands sent from adb clients—all adb clients use port to communicate with the adb server. The server then sets up connections to all running devices. 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'". This is the answer. The syntax is the format you should follow when giving an instruction, for the system to recognize it. The -d, -e and -s are parameters that specify the device to which the adb shell should tunnel the commands to.

Can return an error if more than one is connected. There are ways you can turn your phone on and off without even touching the power button. Flashboot is another tool that can be used to do a lot of critical operations just from the command console. You can launch the flashboot as an application or from the adb program shell itself. But, messing around with adb can seriously brick your device and we are not responsible for any such events.

Generally, it executes when the device is online but it can be programmed to wait till another process is done. Like, installing an apk. After the execution, the shell terminates itself. Almost all of the Android guides are based on ADB as it is a very powerful tool offered by Google and it facilitates a seamless connection between your Android device and a computer. In this guide, we will cover everything about ADB and Fastboot in the most detailed yet simplified way possible.

Read ahead to know more and download ADB and Fastboot for your computer. There are two easy ways by which you can install ADB and Fastboot drivers on your computer. We shall see how to download and install both of them in the upcoming guide. If the latest one does not work for you, you can try downloading one of the older versions.
