Why ADB Devices Shows Offline

What is ADB?

ADB, or Android Debug Bridge, is a tool that allows you to communicate with your Android device from a computer. It’s a powerful tool that can be used for a variety of purposes, including debugging apps, installing new software, and backing up data.

Why Might ADB Show a Device as Offline?

There are a few reasons why ADB might show a device as offline, even if it’s connected to your computer. Some of the most common reasons include:

• USB Debugging is Not Enabled: USB Debugging must be enabled on your device in order for ADB to communicate with it. This setting is usually found in the Developer Options menu.
• Faulty USB Cable: The USB cable you’re using might be faulty or damaged, preventing ADB from establishing a connection with your device.
• Outdated ADB Drivers: Outdated ADB drivers can also cause ADB to show a device as offline. Make sure you have the latest ADB drivers installed on your computer.
• Device Drivers are Not Installed: If you’re trying to connect to a new device, you may need to install the appropriate device drivers on your computer.
• ADB Server is Not Running: The ADB server needs to be running in order for ADB to work. You can start the ADB server by running the following command in a terminal window:

adb start-server
