If you do no see adb file in plateform-tools folder then you have to manually download the plateform-tools folder from above link and copy and paste to android sdk folder — Muhammad Irfan.
I replaced the platform-tools in my sdk location and now everything is good.! Later I found my antivirus removed adb. The same problem. Exactly the same problem, I am using avast as well.

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. This package is required to build Android apps. Most of the tools in here are invoked by the build tools and not intended for you.
However, the following command line tools might be useful:. Note: You can have multiple versions of the build tools to build your app for different Android versions. These tools are updated for every new version of the Android platform to support new features and sometimes more often to fix or improve the tools , and each update is backward compatible with older platform versions.
Note: Prior to revision Jetifier reads a library that uses Support Library classes, and outputs an equivalent library that uses the newer AndroidX classes.

There can be some more issues that Android users face in Android studio as they are not able to locate ADB.
There are different solutions to this problem some work for one or for other Android studio. Sometimes it works for one but not for the other this because of the nature of the problem due to which it is unable to locate ADB.
