[android] adb connection over tcp not working now

I was trying to use adb over TCP/IP. I have followed these steps

adb tcpip 5555

adb connect 194.68.0.100:5555

I have used my device for 2 days and now I am unable to connect to my IP address like when I do

adb tcpip 5555

it doesn't respond anything. Anyone knows what could be the scenario.

ADb used to work fine for me for a week. But now suddenly today it says the machine actively refused connection.

fix:

step 1: go check you phone's IP Adress once again, it keeps changing.
step 2: If it changed. Just use that new IP to connect.

Hope it helped someone :)

Just Try to Debug Mode ON or OFF and then try to reconnect it.

if it dosn't work then connect with USB and try following command in terminal

adb tcpip 5555

and now try with connection command

adb connect Your Phone IP:5555

if you use Android M:

Step 1 : adb usb
Step 2 : adb devices
Step 3 :adb tcpip 5556
Go to Settings -> About phone/tablet -> Status -> IP address.
Step 4 : adb connect ADDRESS IP OF YOUR PHONE:5556

This answer is late, but hopefully it helps others.

I have had the same experience of not being able to connect. Rebooting phone and PC does not help. I found the fix at: http://developer.android.com/tools/help/adb.html at the bottom of the page.

Basically you follow these steps:

1. Connect phone with usb cable to PC.
2. Issue command: adb usb
3. Issue command: adb tcpip 5555
4. Issue command: adb connect xxx.xxx.xxx.xxx

Where xxx.xxx.xxx.xxx is your phone's IP address.

Step 1 . Go to Androidsdk\platform-tools on PC/Laptop

Step 2 :

Connect your device via USB and run:

adb kill-server

then run

adb tcpip 5555

you will see below message...

daemon not running. starting it now on port 5037 * daemon started successfully * restarting in TCP mode port: 5555

Step3:

Now open new CMD window,

Go to Androidsdk\platform-tools

Now run

adb connect xx.xx.xx.xx:5555 (xx.xx.xx.xx is device IP)

Step4: Disconnect your device from USB and it will work as if connected from your Android studio.

Thanks to sud007 for this answer. In my case, I only need this part of the solution:

In CMD/Terminal:

$ adb kill-server

$ adb tcpip 5555
restarting in TCP mode port: 5555

$ adb connect 192.168.XXX.XXX

This bug brings more errors than unable to connect to 192.168.XXX.XXX:5555: Connection refused. In my case, I could connect to the device, but when you try to run the app. AndroidStudio stay in Installing APK forever. In this case, I needed to restart the phone too.

I couldn't do it on a Galaxy S3 (non rooted).

For me it would hang saying...

restaring in tcp mode

So i found this series of commands quite useful.

First disconnect your device, start from scratch (cmd in admin mode and all the stuff).

connect your device and write in CMD/Terminal:

adb kill-server

control should return as normal. Now type and enter

adb tcpip 5555

you will see..

• daemon not running. starting it now on port 5037 *
• daemon started successfully * restarting in TCP mode port: 5555

and then connect device with

adb connect <IP>

That's how it worked for me after a lot of hassle!

UPDATE FOR ANDROID STUDIO

I noticed this doesn't work sometimes, even after correctly repeating steps a number of times. Catch was; sometimes ADB is yet not initialized by Studio unless, Android Tab at the bottom is opened and you see "Initializing Android Studio".

I solved that issue follow that:

Steps:

1. Make sure that Aggressive Wi-Fi to Cellular handover under Networking section in the device's developer options is turned off.
2. Ping continuously from your pc to the device to make sure it's not in network idle mode ping -t 194.68.0.100 (windows cmd), unlock the device and even try to surf to some website just to make it get out of the network idle.
3. If ping doesn't work, turn off / on Android Wifi and go back to step 2.

4. When it replies to the ping, connect it via USB, and:

   adb usb

   adb tcpip 5555

   adb connect 194.68.0.100:5555

In casr it's still not connected, try to switch the usb connection mode as MTP / PTP / Camera while the device is connected through usb and repeat these steps over again...

Just a tiny update with built-in wireless debugging in Android 11:

• Go to Developer options > Wireless debugging
• Enable > allow
• Pair device with pairing code, a new port and pairing code generated and shown
• adb pair [IP_ADDRESS]:[PORT] and type pairing code.
• done
