Learn how to fix the common error "ADB cannot connect to daemon" in this step-by-step guide. Get your Android device running smoothly and connect with ease using these simple troubleshooting tips.

Are you experiencing issues with your Android Debug Bridge (ADB) not connecting to the daemon? This can be a frustrating problem that can prevent you from developing and debugging apps on your device. Fortunately, there are several ways to fix this issue, and in this blog post, we'll discuss some of the most effective methods.

ADB is a command-line tool that allows developers to communicate with an Android device. It's an essential tool for debugging and testing Android apps, and it's used by developers all over the world. However, sometimes ADB can't connect to the daemon, which can be a headache for developers. This issue can occur due to several reasons, including a faulty USB connection, disabled USB debugging, or interference from security measures like firewalls and antivirus programs.

Restart the ADB Server

The first method to fix this issue is to restart the ADB server. This can be done easily by running a command in the terminal. Here's how to do it:

1. Open the terminal and type "adb kill-server"

2. Press enter

3. Type "adb start-server"

4. Press enter

This will restart the ADB server, and it should fix the issue. Restarting the ADB server can help resolve any communication issues between the device and the computer.

Check Your USB Connection



Another common reason for the ADB daemon connection error is a faulty USB connection. Here's how to check your USB connection:


1. Disconnect your Android device from the computer


2. Use a different USB cable to connect the device to the computer


3. Check if the device is properly recognized by the computer


If the device is not recognized, you may need to install the proper drivers or update them to ensure that the device is properly connected to the computer.

Make Sure USB Debugging is Enabled


Another common reason for the ADB daemon connection error is disabled USB debugging. Here's how to enable USB debugging:


1. Go to your device's Settings


2. Go to Developer Options


3. Enable USB Debugging


Enabling USB debugging is necessary for communicating with your device through ADB. If it's disabled, ADB won't be able to connect to the device.

Disable Firewall and Antivirus


Sometimes, security measures like firewalls and antivirus programs can interfere with ADB. To fix this issue, you may need to temporarily disable these programs. Here's how to do it:


1. Go to your computer's Control Panel


2. Click on System and Security


3. Click on Windows Firewall or Antivirus program


4. Turn off the program temporarily


Make sure to turn the program back on once you've finished debugging your app.


In conclusion, there are several ways to fix the ADB daemon connection error. Restarting the ADB server, checking your USB connection, enabling USB debugging, and disabling firewalls and antivirus programs can all help resolve the issue. By following these steps, you should be able to get ADB up and running again and continue developing and debugging your Android apps.
