Hello!
I am trying to find a way that I can only communicate over wifi with the adb on my device. So that for example if someone plugs in an USB cable to his pc, he should not be able to see my device as adb device. The only way to do something with adb should be over wify.
Is there any way to do that, or is the usb adb always on if adb is activated ?
For anyone finding this thread in the future (like I just did looking for solutions), as of about Android 11 and up, adb works over wi-fi (without USB) on non-rooted Android phones via Developer options Wireless debugging switches.

I'm having issues with my laptop detecting attached adb devices (Thunderbolt specifically). I can get my main computer to recognize/detect an adb device. I will then disconnect my phone from my main computer and plug it into my labtop, and yet my laptop will not recognized there's an adb device attached. Regardless of the following, i still can not get it to work on my laptop: Closing CDM, disconnecting the phone from the computer, plugin the phone back then pull up cmd (or pull up cmd and then plug in phone -ive tried every common sense trick there is).
Whats going on with my laptop that will not allow it/android sdk to recognize the device? How do I fix this?
PS in case it needs to be mentioned, yes i have USB Debugging selected (thats why i am able to get the one computer to recognize it).
never mind i'm an idiot, since i manually add the script in for the USB drivers i forgot to select where to pull the drivers from in device manager. Sorry about this post, please delete it.
ADB over Wi-FiSome of us might like to connect the device over WiFi for debugging, instead of using the data cable. Here's the required tutorial to do so
Requirements
1. Android device (duh!!!)
2. ADB in the computer (again duh!!!)
3. Root privileges
4. Terminal emulator (download from here)
Let's begin thenOpen terminal emulator on your device. Enter the following code
Code:
su [color="red"]Grant superuser here[/color]
setprop service.adb.tcp.port 5555 [color="red"]Can be anything else[/color]
stop adbd
start adbd
Check it with this
Code:
getprop service.adb.tcp.port
It will return 5555 or the number you entered in the above code
Enter the following code on your computer in command prompt or shell
Code:
adb connect 192.168.0.151
Instead of 192.168.0.151, enter your device IP address
To make your device listen on USB again, just restart the device. And enter the code on your computer
Code:
adb usb
I would definitely use the USB cable to push large files or even small files that you really don't want to risk corrupting (partition images you plan on dding, etc).
Very importantly, keep in mind, when your phone is listening for adb via WiFi, it's wide open... anybody that has adb installed and knows your device's IP address can access it without a password. Again, a simple reboot will turn it off though.

I want to thank the OP, however belatedly, for writing these root instructions for users to connect their PC and phone via adb over Wi-Fi without USB cables being involved.
As the OP is well aware, non-rooted Android 10 and below allowed wireless adb connections AFTER a USB connection was first established (adb start-server && adb tcpip 5555 && adb connect [IP]:5555), but that changed (for the better) in Android 11 and above with the new new Developer options Wireless debugging random port assignments (adb connect [IP]:[PORT] or adb pair [IP]:[PORT] [PIN]) such that the adb wireless connection never needs USB cable ever again.
Given Android 11 allows Developer options Wireless debugging via a random port, and Android 12 new Developer options Wireless debugging allows that to be accessed even easier with a new Developer options Wireless debugging tile, the only thing missing is a way to get, after the fact, the random port assignment that Android uses for the adb wireless connection to your PC.
Some related threads for reference might be...

(PSA) Using the new Android 12 TILE for 'Developer options' 'Wireless debugging' to establish adb connection over Wi-Fi without USB
What's the difference between Windows/Android adb "connect" versus adb "pair" when mirroring Android 12 over Wi-Fi onto a Windows PC?
The only question that's missing an answer preventing a perfect completely Wi-Fi automatic solution is...
Does anyone know how to obtain that random Android port address from the PC?
You can enable ADB through network while keeping the USB active for devices.
The best way I found was to sideload the app "WiFi ADB - Debug Over Air"
From the computer
ADB connect *IP ADDRESS*
I use ADB Link. Works wonderful.
(Many will consider this question a duplicate of similar questions but I don't think this question should be marked as duplicate because the answer requested here is different than others.)
I am searching for the solutions since many years and read a lot of pages on internet and StackOverflow but hasn't found any solution.
Once an non-rooted Android phone is authorized over USB using ADB then how to connect it over Wi-Fi every time without ever connecting the phone over USB?
I know that executing
Code:
adb start-server
then
Code:
adb tcpip 5555
and then
Code:
adb connect <IP.address.of.phone>
will connect the phone over Wi-Fi IF it is connected using USB when issuing these commands.
According to the answers/forums, there are 2 ways to connect Android phone over Wi-Fi:
The user has to first connect to USB even though the device is already authorized.
The phone needs to be rooted.
But I think, what I want to achieve, as per the question, must be possible because if ADB can connect over USB and then Wi-Fi, then there must be some way to accomplish with directly connecting over Wi-Fi if computer is already authenticated. The missing thing is to know what exactly ADB is doing when switching from USB to Wi-Fi. I think, it could be getting authorization again. But what if we store the authorization information (finger print? or encryption key?) once and use it every time to connect over Wi-Fi? (Please note that when first time authenticating the computer over USB, its finger print is showed in the Android phone, and it never asks again until the authorization is revoked/invalidated somehow. So, I think the requirement here is to revalidate the computer.)
I viewed the ADB repository and read the text files mentioning how ADB works. In one txt file I read that
Code:
adbd
(ADB Daemon) is started on port 5555 on the Android phone/emulator when
Code:
adb connect ___
command is executed. Is there anyway to manually start the daemon through a terminal app on the installed on phone? I tried 'adb', 'adbd' and 'setprop' commands in the Termux app but these commands doesn't exist. According to the txt files of the repository, the ADB on computer is sending the commands to the Android device/emulator and can start 'adbd' or set/open the port 5555 using
Code:
setprop service.adb.tcp.port 5555
command. Is there a way to do this on Android phone using a terminal app on a non-rooter phone?
Somebody who has knowledge of networking, Android and C/C++ language may be able to answer. One can look in the GitHub repo of ADB source code if they want to know what is happening during the connection process.
I'm a little late to answer your question at the time you asked it, but if it still helps the OP, non-rooted Android 10 and below allowed wireless adb connections AFTER a USB connection was first established (adb start-server && adb tcpip 5555 && adb connect [IP]:5555), but that changed (for the better) in Android 11 and above with the new new Developer options Wireless debugging random port assignments (adb connect [IP]:[PORT] or adb pair [IP]:[PORT] [PIN]) such that the adb wireless connection never needs USB cable ever again.

Has anyone tried to ADB over different wifi? My friend lives far away and wants to root his phone but doesn't have a computer. Is it possible for me to use my computer TO root for him, maybe via hamachi??
Thanks in advice for suggestions
ADB Wireless requires the phone's Android must be rooted.

Setting Up ADB on Windows and Connecting Wirelessly to Android
How to Set up ADB on Windows Platform Android Debug Bridge (ADB) is a tool that gives you options to modify, tweak, or debug your Android device. The ADB establishes a connection between your PC and Android device or emulator (for development purposes) through a built-in server.
