adb connection over tcp not working now

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.

Try to do port forwarding,

adb forward tcp:<PC port> tcp:<device port>.

like:

adb forward tcp:5555 tcp:5555.

sounds like 5555 port is captured so use other one. As I know 7612 is empty

[Edit]

C:\Users\m>adb forward tcp:7612 tcp:7612C:\Users\m>adb tcpip 7612restarting in TCP mode port: 7612C:\Users\m>adb connect 192.168.1.12connected to 192.168.1.12:7612

Be sure that you connect to the right IP address. (You can download Network Info 2 to check your IP)

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.
