When To Use

Utilize 'adb forward --remove-all' in scenarios where unstable or redundant port forwarding configurations impede Android app debugging or deployment processes. This is critical when experiencing connection conflicts or when preparing a fresh development session with new forwarding rules.

Pro Tip

Although 'adb forward --remove-all' clears all current rules, it does not warn about connections currently using these forwarded ports. Monitor logs for hidden connection drops.

Warning

Destructive operation. Confirm the target path and keep a backup before executing.

Anatomy of Output

Understanding the result

No direct terminal output after execution. Command Execution

The command success is indicated by the absence of error messages.

Error: could not remove forwarding rules, 1000: unauthorized. Potential Errors

Ensure the device is properly authorized and connected.

Error: adb server is out of date. Killing... Server Out-of-Date Error

The ADB server needs to be restarted to continue.

Restarting ADB server... Server Restart

Occurs automatically if the server is out of date.

Error: failed to clear forwarding rules, 733: transport error. Transport Error

Indicates communication issues with the device, possibly due to USB connection problems.

Power User Variants

Optimized versions

adb -s <device_serial> forward --remove-all

Removes forwarding rules for a specific device using its serial number. This targets exact devices in multi-device setups.

Unix Pipeline

Shell combinations

adb forward --list | grep '<local>' | awk '{print $1}' | xargs -I {} adb forward --remove {}

Remove specific forwarding rules matching a pattern without clearing all by using filtering and specific removal.

Troubleshooting

Common pitfalls

1000: unauthorized

Solution: Reconnect the device and ensure authorization dialogue is accepted.

ADB server is out of date

Solution: Update your ADB and restart the server.

733: transport error

Solution: Recheck USB connections or switch ports.
