You can find the adb tool in /platform-tools/

cd Library/Android/sdk/platform-tools/

You can check your devices using:

./adb devices

My result:

List of devices attached
XXXXXXXXX   device

Set a TCP port:

./adb shell setprop service.adb.tcp.port 4444

./adb tcpip 4444

Result message:

restarting in TCP mode port: 4444

To init a wifi connection you have to check your device IP and execute:

./adb connect 192.168.0.155:4444

Good luck!

Try below android studio plugin

Android WiFi ADB

HOW TO

1. Connect your device to your computer using a USB cable.
2. Then press the button
   
   on the toolbar and disconnect your USB once the plugin connects your device over WiFi.
3. You can now deploy, run and debug your device using your WiFi connection.

Github Link: https://github.com/pedrovgs/AndroidWiFiADB

NOTE: Remember that your device and your computer have to be in the same WiFi connection.

Step 1: Goto your Android sdk folder -> platform tools and copy the whole path

For example: C:\Program Files (x86)\Android\android-sdk\platform-tools

Step 2: Goto command prompt or Android studio terminal

cd C:\Program Files (x86)\Android\android-sdk\platform-tools

and press enter

Step 3: Connect your device & system with same wifi.

Step 4: Type adb tcpip 5555 and press Enter.

Step 5: Type adb connect x.x.x.x:5555, replacing the x.x.x.x with your phone IP address.

find out phone IP address

Settings -> About phone -> Status (some phones may be vary)

Note: In case that you connect more than one device, disconnect other phones except the one you need to connect.

I used the following steps to successfully debug over wifi connection. I recommend this solution to everybody experiencing problems using integrated solutions like Android WiFi ADB plugin. In my case it failed to keep the Wifi connection to my device after unplugging USB. The following solution overcomes this problem.

1. Connecting device

a. Connecting device using local wlan

If you have a local wlan you can connect your android device and your pc to this wlan. Then identify the IP address of the android device by looking into its wlan settings.

b. Connecting device directly using a hotspot

I prefer to connect with a hotspot on the device. This is more private and does not open your debugging connection to the (public) wlan.

1. Create a Wifi hotspot on the Android device
2. Connect PC to hotspot
3. On PC look into network connection status of this hotspot connection to find the IPADDRESS of your device.
   My system showed IPADDRESS 192.168.43.1

2. Create debugging connection

1. Connect your device to USB.
2. Issue command adb tcpip 5555 to open a port on the device for adb connection.
3. Create wireless debugging connection adb connect IPADDRESS.
   In my case the command looked like adb connect 192.168.43.1

The command adb devices -l should now display two devices if everything is ok. For example:

List of devices attached
ZY2244N2ZZ             device product:athene model:Moto_G__4_ device:athene
192.168.43.1:5555      device product:athene model:Moto_G__4_ device:athene

3. Keeping debugging connection

The tricky part comes when unplugging the USB connection. In my case both connections are closed immediately! This may not be the case for all users. For me this was the reason that I could not use Android WiFi ADB plugin for android studio. I solved the problem by manually reconnecting the Wifi after unplugging usb by

adb connect 192.168.43.1

After that adb devices -lshows a single wifi connected device. This devices shows also up in android studio and can then be selected for debugging. When the connection is unstable you may need to repeat the above command from time to time to reactivate the connection.

Try to run:

adb tcpip 5555
adb connect 192.168.2.4

You may need to restart your adb via Android Studio (do it twice for good measure).

If you are using a rooted phone then try this application WiFi ADB.
Probably this is the most simplest way to debug on wifi.
I am using this application from many days and it works flawlessly.

I'm using AS 3.2.1, and was about to try some of the plugins, but was hesitant realizing the plugins are able to monitor any data..

It's actually really simple doing it via the Terminal tab in AS:

1. Turn on debugging over WiFi in your phone
   • Go to developer options and turn on "ADB over network"
   • You'll see the exact address and port to use when connecting
2. Go to the Terminal tab in Android Studio
3. Type adb tcpip 5555
4. Type your ip address as seen in developer options i.e. adb connect 192.168.1.101
5. Now you'll see your device in AS "Select deployment target" dialog

In Android Studio 3.0.1 > Goto > (Short cut key (Alt+Cltr+S)) Settings > Goto Plugins > Click on Browser repositories... > Search "ADB WIFI" and install the plugin. After the installation restart your android studio.

Here are simple steps to implement Android App debugging using ADB over wifi:

Required: You need to connect android device and computer to the same router via wifi. You can use Android Wifi tethering also.

Step 1: Connect Android device via USB (with developer mode enabled), and check its connection via adb devices.

Step 2: Open cmd/terminal and the path of your ../sdk/platform-tools.

Step 3: Execute command adb devices.

Step 4: Execute command adb -d shell (for device) OR adb -e shell (for emulator). Here you will get the shell access to the device.

Step 5: Execute command ifconfig and check the ip-address of it.

Step 6: Not disconnect/remove device USB and execute command adb tcpip 5000, to open tcpip socket port 5000 for adb debugging. You can open it on any port which is not currently occupied.

Step 7: Now execute command adb connect <ip-address>:<port>. eg: adb connect 192.168.1.90:5000 (where ip-address is device's wifi address and port which you have opened).

Now, run adb device and check the debugging device is now connected wirelessly via wifi.

Happy Coding...!

just open settings / plugins / search " Android wifi adb and download it and connect your mobile using usb cabble once and its done
