I am beginner in android.My problem is I had connect my mobile device with adb through adb tcpip 5555 and adb connect command in the cmd (first time via cable) and it successfully work and work wireless in android studio but on the next day when I am reconnecting with my device it does not work until I repeat the process again that is for the first time do all the process via cable and make connection.
So My Question is, Is there is any solution available that adb connection require only one time setting and after that it work until I dissconnet manually, Also I want the solution without rooting the android phone
You need to follow this step first time at least
1)adb tcpip 5555
2)adb connect 192.168.0.101:5555
after that badly your device disconnect then you need to do above step again but one thing is there first hit this command and then follow above two step
1.adb kill-server
2.abb start-server
By the way it does not required root phone.

Everytime I want to connect my adb server to my device, I need to explicitly give the port.
adb connect localhost:<port>
On my case, the port is randomly defined so I have to find it on the interface.
I try to netstat my computer but the port does not appear, except if I adb connect, and just a moment after I adb disconnect. But then it disapear again.
An other thing I thought was to brut force all ports but it takes like an ethernity..
If you have a suggestion I would be glad to read and test it.
Thanks
I'm using Android tablet communicating with a USB device through USB port, the tablet only has one usb port, so I use adb wifi as my debug tool. However, when I connect adb through WIFI, the connection won't keep long(only a few minutes us usually), how to keep the adb wifi connection online all the time?
Another question, is it possible to use USB HUB to connect the tablet with both USB flash-drive and my computer, and keep adb running?
Many thanks!!!
After lots of unsuccessful attempts,I have noticed that turning Allow ADB debugging in charge only mode specification on , solved the problem . It makes the device online and accessable over wifi to ADB.
You can find it under Developer options section.
Here is what I found out from researching everywhere and developing on my own for more than a week.
Q1. adb service often crashes if it is not doing any executions for a long long time.
A1. calling adb commands time to time keeps adb server online.
Q2. wifi connected device sometimes disconnect.
A2. Before you check your wifi on the connected device, check the wifi that your ADB server is running on. Ping to google and if it is well connected, ping to the device.
Wireless can disconnect on its own and even wired connection is sometimes disconnected. so calling "adb connect ..." when the device is not already connected is necessary. You could do this easily by saving "adb devices > device.txt" and query out whether your expected wifi is on the list. If not, connect again..(do this in another thread).
Q3. wifi connected device is sometimes offline.
A3. This is because by TCP/IP connection your ADB server is now on Time_Wait stance. The last connection was interrupted that the next connection is now offline because the last connection is not completely shut down. You can either manually disconnect/connect your device's wifi or restart TCPIP connection by ex) "adb tcpip 5555"
If you want to do this automatically, you are going to have to disconnect/connect your device's wifi programmatically.
Leave any other questions and I can answer on the comments.
When connection is lost and adb devices shows device is offline, like this:
prompt> adb devices
List of devices attached
192.168.1.1:5555 offline
then adb disconnect IP followed by adb connect IP will often work:
prompt> adb disconnect 192.168.1.1
disconnected 192.168.1.1
prompt> adb devices
List of devices attached
prompt> adb connect 192.168.1.1
connected to 192.168.1.1
prompt> adb devices
List of devices attached
192.168.1.1:5555 device
Use adb over wi-fi without any third-party apps. Follow the steps.
Connect device via USB
Open your terminal and check your device is listed with adb devices command
Type adb tcpip 5555 and enter (or use another port instead of 5555)
Plug out your USB cable. You don't need it anymore.
Take your Android phone and go Settings/About/Status
Check the IP address part. Let's say your IP address is 192.168.x.y
In your terminal, write the command adb connect 192.168.x.y
Now, you have connected your device via wi-fi.
You can see your device in adb devices
Enjoy it! :)
This seems like an issue with your wifi. As a precaution, just keep the terminal open and whenever you need to test just press the 'UP arrow' key to get to previously ran adb connect "<ip>" command.
I tried many ways but this one worked out for me:
force the display on and of in a loop would keep the device online
adb shell input keyevent 224
timeout 2
adb shell input keyevent 26
timeout 58
this turns the display on every minute for 2 seconds
So, I'm using Scrcpy and Adb to wirelessly connect to my Phone(for developing Flutter Apps) and since the screen wasn't staying awake even by Scrcpy --stay-awake command.
I had to change Lock Settings=>Lock Screen => Sleep, and settings to Never Sleep.
I have read all the relative threads about ADB not recognizing devices. My case though is different: ADB sometimes "sees" my phone (Samsung Galaxy) and other times NOT. No matter how many times I kill and restart the ADB service or I disconnect and reconnect the device from/to the PC. Quite an unstable situation here. You know, it's one of these things that drives you crazy. That's why I resorted to your help.
Has anyone had this exact problem and resolved it once for all?
More info:
The PC has never a problem recognizing the device.
I try with both the standard SDK adb.exe and the Universal ADB driver adb.exe.
Either of the above have no problem recognizing the emulator.
Couple things.
1) it's a dumb suggestion but sometimes its as simple as this. Did you try more than one cable?
2) If yes, then try this. try as many times as you have to get it connected since u said "ALWAYS" so it does work sometimes. When it does work, open terminal or command line and run the following commands.
(make sure device is connected when you do this AND you are on the same wifi network)
adb tcpip 5555
then disconnect your phone and run the following command:
adb connect YOUR_LOCAL_IP
do this many times, this is wireless adb connection and if this works, its something with ADB or your computer and not the phone.
Let me know if it works. I might have more ideas depending on what result you get
============ EDIT ============
I believe it's offline because it says 8080. I just did the same with my phone and I get the following:
Try this: disconnect phone physically (if connected) and all other devices and make sure by doing: adb disconnect.
then, do adb kill-server
then, on your phone, go to Developer Options and uncheck USB debugging.
then, right underneath that options, there is Revoke USB debugging authorizations options. select and revoke all devices
then, check USB debugging
then, back on your computer, run adb start-server
then, try reconnecting with the steps I said before. make sure port is 5555
when you run the adb connect command, make sure to add the port at the end.
example: adb connect 10.0.0.15:5555
Hope this works.
So I have been following a few tutorials online for setting up android app debugging through wifi, since my USB connection is broken.
The first command line input is giving me problems.
I type in
adb tcpip 5555
and get this message:
Restarting in TCP mode port 5555
This message just hangs and the process never finishes.
I tried different port numbers, same thing. Tried to connect to my device IP and no luck.
Any ideas?
Just plug out your USB wire at that moment and it will connect.
Make sure desktop and device is connected the same network? and
1) Switch on wi-fi
2) adb tcpip 5555 - it restarts your device
3) adb connect deviceIpAddress:5555
4) Unplug your device and run project
Enjoy the life ))))
I have the same problem sometimes, when that happens, use 5556 or other port. that works for me.
When adb tcpip 5556 is not responding, remove your data cable and reconnect cable
adb shell netcfg - for finding phone ip.
adb connect ip:5556 the device will be successfully added.
adb devices - list all devices connected.
I know it's an old thread but it may still help others. My problem solved when I changed my android device usb connection mode from Usb Mass Storage to MTP inside android usb settings.
i had the same issue.
in my case i saw there is two cmd opened,
closed another cmd and its worked for me
We have test suite where adb clients connect to multiple android devices.
Our test suite raises these requests to connect, get device state and run applications in it.
I would like to simulate a scenario where adb server hangs.
I tried issuing "adb kill-server" but any adb request from client starts the adb server.
Is there anyway we can stop the adb server from listening to adb client requests ?
Of course there is a long way of compiling adb service and changing the code our self.
But any easy way to get this done?
Do you need to still have a connection (that doesn't respond to commands), or is it fine to kill the connection altogether? Sounds to me like killing the connection would be fine since you say that you tried adb kill-server.
In that case, how about trying to connect to the device in TCP/IP mode without having set up the adb server to listen on a network port? I.e. something like:
adb tcpip 12345
Another suggestion would be to actually disable adb interface totally in the device. While this may or may not stop the adb server, you would still get your desired result i.e no connection for adb clients.
The way this could be done is that on a ROOTED device, do
adb shell
su
echo 1 > /sys/class/android_usb/f_adb/on
This one is what I could do on an HTC Vivid which I have on hand. For other devices, the paths might be different but they should all be similar. Once your reboot the phone, adb starts working again.
