[android] Run/install/debug Android applications over Wi-Fi?

I thought there was a way to test your applications in development over Wi-Fi. Is this possible?

I'd love to be able to untether my phone and develop wirelessly.

I wrote a simple script for Windows:

Step 1. Make a batch file with the below commands and call the file wifi_dedug.bat and copy the below contents:

    adb tcpip 5555
    pause
    adb shell "ip addr show wlan0  | grep 'inet ' | cut -d' ' -f6|cut -d/ -f1" > tmpFile 
    pause
    set /p ip= < tmpFile 
    @echo %ip%
    del tmpFile
    @echo %ip%
    adb connect %ip%
    pause

Step 2. connect your device to pc.

Step 3. start batch file (key enter when requested)

Step 4. disconnect your device and deploy/debug via wifi.

1. make sure your pc and android is on same wifi connection.

2. start adb server from your phone... download any wireless adb app from playstore...here is what I am using WiFi ADB - Debug Over Air

3. on your computer start cmd and run: Code (csharp): adb connect 192.168.1.100:5555 Be sure to replace 192.168.1.100 with the IP address that is actually assigned to your device.

check if it is connected by : Code (csharp): adb devices 4. start unity or restart if it is already running and hit play..

5. tadaa...........:eek:

I found my answer here:

1. Connect Android device and adb host computer to a common Wi-Fi network accessible to both. We have found that not all access points are suitable; you may need to use an access point whose firewall is configured properly to support adb.
2. Connect the device with USB cable to host.

3. Make sure adb is running in USB mode on host.

   $ adb usb
   restarting in USB mode
   

4. Connect to the device over USB.

    $ adb devices
    List of devices attached
    ######## device
   

5. Restart host adb in tcpip mode.

   $ adb tcpip 5555
   restarting in TCP mode port: 5555
   

6. Find out the IP address of the Android device: Settings -> About tablet -> Status -> IP address. Remember the IP address, of the form #.#.#.#. sometimes its not possible to find the IP-address of the android device, as in my case. so u can get it using adb as the following: $ adb shell netcfg and the should be in the last line of the result.

7. Connect adb host to device:

   $ adb connect #.#.#.#
   connected to #.#.#.#:5555
   

8. Remove USB cable from device, and confirm you can still access device:

   $ adb devices
   List of devices attached
   #.#.#.#:5555 device
   

You're now good to go!

If the adb connection is ever lost:

1. Make sure that your host is still connected to the same Wi-Fi network your Android device is.
2. Reconnect by executing the "adb connect" step again.

3. Or if that doesn't work, reset your adb host:

    adb kill-server
   

and then start over from the beginning.

When you follow the above answer https://stackoverflow.com/a/10236938/6117565, you might get the error "No route to host".

To fix that, before step 5 in the above answer, first, start your emulator then try the connecting device. Don't know what is happening but this trick works.

With new Android 11 you can debug your apps over WiFi without using an USB cable at all.

Quoting from Android Studio User Guide

Connect to a device over Wi-Fi (Android 11+)

Android 11 and higher support deploying and debugging your app wirelessly from your workstation using Android Debug Bridge (adb). For example, you can deploy your debuggable app to multiple remote devices without physically connecting your device via USB. This eliminates the need to deal with common USB connection issues, such as driver installation.

To use wireless debugging, you need to pair your device to your workstation using a pairing code. Your workstation and device must be connected to the same wireless network. To connect to your device, follow these steps:

1. On your workstation, update to the latest version of the SDK Platform-Tools.
2. On the device, enable developer options.
3. Enable the Wireless debugging option.
4. On the dialog that asks Allow wireless debugging on this network?, click Allow.
5. Select Pair device with pairing code. Take note of the pairing code, IP address, and port number displayed on the device (see image).
6. On your workstation, open a terminal and navigate to android_sdk/platform-tools.
7. Run adb pair ipaddr:port. Use the IP address and port number from step 5.
8. When prompted, enter the pairing code that you received in step 5. A message indicates that your device has been successfully paired.

    none
    Enter pairing code: 482924
    Successfully paired to 192.168.1.130:37099 [guid=adb-235XY] 

9. (For Linux or Microsoft Windows only) Run adb connect ipaddr:port. Use the IP address and port under Wireless debugging.

The adb utility does have the ability to connect to a device over TCP/IP. However, adbd is not normally listening for TCP connections.

If you want to get it running, you need an engineering device (in other words, you need root). Then follow the directions in this post:

How can I connect to Android with ADB over TCP?

Since this only works on eng devices, it's not officially supported. Use at your own risk, expect bugs, etc.

If you are using Android 11 click on the build version many times to activate the developer option then go to Settings>Advanced>Developer options. Scroll to debugging and turn on the "Wireless debugging" checkbox. Then open the menu debugging by touching the "Wireless debugging". Select "Pair device with paring code" and you will see the address for pairing with a pairing code. write this command in your desktop terminal to pair with your Android device.

adb pair 192.168.XXX.XXX:XXXX   <--------- the address showing on screen under paring code

Use the paring code to connect.

But wait we are not connected to adb yet. After you have successfully paired your device once. You can connect your adb anytime you turn on your Wireless debug option. To connect your adb every time before you use it from now on you don't need the pairing address anymore instead you will use the given address that shows when you enter the Wireless debug menu.

adb connect 192.168.XXX.XXX:XXXX    <--- this address shows inside wireless debug menu

For Windows:

Step 1. Make a batch file with the below commands and call the file w.bat.

Step 2. Copy the below contents in w.bat, and save it in any of the folders which are in %path% of your Windows system

echo ***Get phone in Wi-Fi mode***
echo ***Get phone in Wi-Fi mode***

adb devices
echo ***Remove cable from the phone now***
adb tcpip 9000

adb connect 192.168.1.1:9000
adb connect 192.168.1.2:9000
adb connect 192.168.1.3:9000
adb connect 192.168.1.4:9000
adb connect 192.168.1.5:9000
adb connect 192.168.1.6:9000

//<-- Till here -->

Step 3. Connect your phone and PC with a cable

Step 4. Ensure the phone is in Wi-Fi mode

Step 5. Remove the cable when the batch file tells you to

Step 6. Type w.bat on the Windows prompt (start -> run -> type CMD, press Enter) (black screen is Windows DOS prompt), if you copied it in one of the path folders then you can run from anywhere, else run from the folder where you created this file.

The output of the batch file will be something like this:

C:\Windows\System32>w

C:\Windows\System32>echo ***Get phone in Wi-Fi mode***
***Get phone in Wi-Fi mode***

C:\Windows\System32>echo ***Get phone in Wi-Fi mode***
***Get phone in Wi-Fi mode***

C:\Windows\System32>adb devices
List of devices attached
d4e9f06 device

C:\Windows\System32>echo ***Remove cable from the Phone now***
***Remove cable from the Phone now***

C:\Windows\System32>adb tcpip 9000
restarting in TCP mode port: 9000

C:\Windows\System32>adb connect 192.168.1.1:9000
unable to connect to 192.168.1.1:9000:9000

C:\Windows\System32>adb connect 192.168.1.2:9000
connected to 192.168.1.2:9000

C:\Windows\System32>adb connect 192.168.1.3:9000
unable to connect to 192.168.1.3:9000:9000

C:\Windows\System32>adb connect 192.168.1.4:9000
unable to connect to 192.168.1.4:9000:9000

C:\Windows\System32>adb connect 192.168.1.5:9000
unable to connect to 192.168.1.5:9000:9000

C:\Windows\System32>adb connect 192.168.1.6:9000
unable to connect to 192.168.1.6:9000:9000

Note 1: Find this in the output, (ignore all ->unable to connect<- errors)

connected to xxx.xxx.x.x:9000

If you see this in the result, just remove the cable from PC and go to Eclipse and run to install the app on the device; that should be it.

Note 2: DISCONNECT OR TO SWITCH WIRELESS MODE OFF: Type the below command. It should say restarting in USB mode - at this stage PC and computer should NOT be connected with a cable:

C:\Users\dell>adb usb
restarting in USB mode

Note 3: Steps to find the IP address of the phone (taken from Stack Overflow)

Find IP address of MY PHONE:

a. Dial *#*#4636#*#* to open the Testing menu.
b. In the Wi-Fi information menu: click Wi-Fi Status
c. Wi-Fi status can be blank for the first time
d. Click Refresh Status
e. In the IPaddr: <<IP ADDRESS OF THE PHONE IS LISTED>>

Note 4: My Phone Wi-Fi connection IP address range typically is as the mentioned IP addresses below,

192.168.1.1

192.168.1.2

192.168.1.3

192.168.1.4

192.168.1.5

192.168.1.6

Note 5: if you get any other sequence of IP addresses which keep getting reassigned to your phone, you can just change the IP address in the w.bat file.

Note 6: This is a brute-force method, which eliminates all manual labor to keep finding IP address and connecting to Eclipse / Wi-Fi.

SUCCESS Note 7: So in short, the regular activity would be something like this:

Step 1. Connect PC and Wi-Fi via a cable
Step 2. Start CMD - to go to Windows DOS prompt
Step 3. Type "w"
Step 4. Find connected command in the output
Step 5. Success, remove cable and start using Eclipse

From search and from some answers i use this method and it work fine and you must know that tcpip is not always 5555 , you must find it just follow this you need first to download platform-tools

https://developer.android.com/studio/releases/platform-tools.html

extract platform-tools folder to C drive and run Powershell there (Right click >> PowerShell >> Open here)

#Connect phone with usb cable

PS C:\platform-tools> adb kill-server
PS C:\platform-tools> adb shell ip route > addrs.txt

#this give you your tcpip

* daemon not running; starting now at tcp:5037 
* daemon started successfully
PS C:\platform-tools> adb tcpip 5037
restarting in TCP mode port: 5037

#Disconnect phone #adb connect <phone_ip>:5037

PS C:\platform-tools> adb connect 192.168.43.1:5037
connected to 192.168.43.1:5037

Now you can see your phone in Android studio

(No root required) There is one best, easy and with UI method for Android Studio

IntelliJ and Android Studio plugin created to quickly connect your Android device over WiFi to install, run and debug your applications without a USB connected. Press one button and forget about your USB cable.

just install plugin Android WiFi ADB

Download and install Android WiFi ADB directly from

Intellij / Android Studio: Preferences/Settings->Plugins->Browse Repositories

.

Remember! for first time to initialize the device you must have to connect using usb

Alternatively, you can download the plugin from the JetBrains plugin site and install it manually in: Preferences/Settings->Plugins->Install plugin from disk.

You can connect and manage your devices easily....... for more information read here https://github.com/pedrovgs/AndroidWiFiADB

android Wireless Debugging (MAC)

step 1: go to sdk folder (common path "/Users/macname/Library/Android/sdk/platform-tools") open cmd here run "adb devices" output - List of devices attached

if adb command not found in cmd type ./adb --help OS X / macOS: typically ~/.profile or ~/.bash_profile Add the following line there and replace the path with the one where you installed platform-tools:

step 2: $ export PATH="/Users/macname/Library/Android/sdk/platform-tools":$PATH

step 3: $ adb devices List of devices attached ZH99FF7FTY device

step 4: $ adb tcpip 5555 restarting in TCP mode port: 5555

step 5: $ adb connect 10.124.32.18:5555 connected to 10.124.32.18:5555

Next Time repeat step 4 and 5 to reconnect Or if Device reboot and not connect follow step again BEST OF LUCK

I use adb shell ip -f inet addr show wlan0 to find the device ip after adb tcpip 5555.

Newer version deprecated adb netcfg. Thus this is the correct way to find the ip of the device when the interface name is wlan0 (default interface name).

Though there are so many good answers, here is my two cents for the future me :P and for anyone who wants it quick and easy.

For Mac:

• connect the device using USB first and make sure debugging is working. Disconnect any other devices and quit emulators.

• open terminal and run the following script

  adb tcpip 5555
  adb connect $(adb shell ifconfig | grep "inet " | grep -v 127.0.0.1 | awk '{print $2}' | cut -d: -f2):5555
  

• disconnect USB connection and the device should be available for WiFi debugging

Explanation:

adb tcpip 5555 commands the device to start listening for connections on port 5555

adb connect $(_ip_address_fetched_):5555 tells to connect on port 5555 of the _ip_address_fetched_ address

where _ip_address_fetched_ includes following:

adb shell ifconfig getting internet configurations using adb shell

grep "inter " filter any line that starts with inter

grep -v 127.0.0.1 exclude localhost.

At this point, output should be like:

inet addr:###.###.#.### Bcast:###.###.#.### Mask:255.255.255.0

awk '{print $2}' get the second part of the components array, separated by space (I'm using zsh).

The output up to this point is

addr:###.###.#.###

cut -d: -f2 split the string by delimiter : and take second part. It will only take your device IP address

Steps for Android Wifi debugging with ADB:

$> adb devices   // check all usb debuggable devices connected.

$> adb -d shell  // Access device shell.

shell> ifconfig  // Check and copy wifi ip-address eg:192.168.1.90

shell> exit      // Exit from android device shell.

$> adb tcpip 5000   // open TCP port 5000 (or any available)

$> adb connect 192.168.1.90:5000  // connect to device via wifi ip over specific TCP port.

$> adb devices   // you will get debuggabled android device over wifi.

Required: Connect your android device to computer via USB with developer mode enabled. Also connect your android device and computer to same wifi router (or use tethering).

After a long search I found :

I must run

adb connect <device_ip_address>:5555 

after disconnecting USB.

One imp point probably missed here - once you do a adb remount - the TCP connection is lost hence you have to do a adb connect IP:port once over again

Following steps are standard ones to follow( mostly same as previous answers):-

• adb tcpip 5555.
• adb connect your_device_ip_address.
• adb devices (to see if devices got connected).

But in some cases above steps gives error like "unable to connect to device. Make sure that your computer and your device are connected to the same WiFi network." And you notice the devices are already on the same network.

In this case, install this plugin "Wifi ADB Ultimate" and follow below steps.

1. Connect the device once through USB.
2. Refresh the list to check whether its connected.
3. Go to About Phone > Status > IP Address and note your IP address(e.g. 198.162.0.105).
4. Come back to Android Studio and fill in this IP as done in below photo and hit the run button.

Now, you are good to go!

The best way is using ADBConnect (Eclipse plugin) and ADB Wireless (app for Android device).

>##    open command prompt with Run as Administrtor ##

    adb connect ipdevice:5037

For Ubuntu / Linux:

1. Make sure your device is working for debugging: http://developer.android.com/tools/help/adb.html#Enabling
2. Go to your sdk folder and find the folder platform-tools
3. Use ./adb devices to list the connected devices. Make sure it is only one device connected and no emulator running.
4. Find your device IP address, you can find it in your device: http://developer.android.com/tools/help/adb.html#wireless, or got adb shell like this: ./adb shell then netcfg. You will see a list of IP addresses. Find wlan0, in my case 192.168.100.3/2.
5. ./adb tcpip 5555
6. Finally enter ./adb connect <Your device IP Address>:5555 in your terminal. You can now deploy the application to your device over Wi-Fi.

To complete the answer of @usethe4ce, if you have more than one device or emulators, the adb tcpip 5555 will give error: more than one device/emulator.

In this case you need to give the serial number of the desired device:

1. adb devices

   List of devices attached

   33001229 device

   emulator-5554 device

2. adb -s 33001229 tcpip 5555
3. Find your device's IP in my case I can find it from the device's wifi connected settings.
4. adb connect xxx.xxx.xxx.xxx:5555

This Android WiFi ADB plugin doesn't work in 4.1.1 (anymore)

But there is much more simple solution: If you have an Android 11 (api30) device you should use Android Studio 2020.3.1 (Canary) to connect. It's super easy

Then you go to developer settings and scan QR code. That's it. You can use connected device in other (older) Android Studio version now as well

If you are a windows user and your android sdk is located at C:\Users\%username%\AppData\Local\Android\Sdk then you can follow this method. If your andoid sdk not located there, replace that path to the below code.

@echo off
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" disconnect
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" shell ip route > %temp%\addrs12321.txt
For /F "UseBackQ Delims==" %%A In ("%temp%\addrs12321.txt") Do Set "lastline=%%A"
FOR %%C IN (%lastline%) DO SET last=%%C
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" tcpip 5555
"C:\Users\%username%\AppData\Local\Android\Sdk\platform-tools\adb.exe" connect %last%:5555 > %temp%\adbresult.txt
set /p result=<%temp%\adbresult.txt
del /f %temp%\addrs12321.txt
echo MSGBOX "%result%" > %temp%\TEMPmessage.vbs
call %temp%\TEMPmessage.vbs
del %temp%\TEMPmessage.vbs /f /q
del %temp%\adbresult.txt /f /q

Step 1.

1. Turn on usb debugging,
2. Connect your phone to windows machine
3. select file transfer in usb options menu in android menu (if found)

Step 2.

1. copy above code

2. save as its extension like .bat, eg filename.bat

3. double click on the file you saved. done

note you can connect any time by running that file while the device being connected with the pc with usb debugging is turned on.

Download the app Wifi ADB on the play store. Very easy to use and works like a charm! :)

Note :- Android Phone must be rooted and no need of usb cable.

Install wifi adb in android phone from playstore

link :-https://play.google.com/store/apps/details?id=com.ttxapps.wifiadb

For Windows

I am using this technique , which is very easy.

1) download adb :

link : https://www.dropbox.com/s/mcxw0yy3jvydupd/adb-setup-1.4.3.exe?dl=0

2) Run exe :- when you see blue screen press y enter .

3) Now open your wifi adb apk , just grant root permission and must be remember you android phone and system on the same network by wifi or hotspot .

4) Open Wifi adb apk , you will get some ip address like , adb connect 192.168.2.134:5555 Note this ip may be very from system to system , now put this information to your command prompt and hit Enter .

5) Open cmd from anywhere enter adb connect 192.168.2.134:5555 .

6) Finally you successfully connected to adb . it will show message like connected to 192.168.2.140:5555

For Mac Os

This is the easiest way and will provide automatic updates.

1)Install homebrew

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

2)Install adb

brew cask install android-platform-tools

3)Start using adb

adb devices

4) Open Wifi adb apk , you will get some ip address like , adb connect 192.168.2.134:5555 Note this ip may be very from system to system , now put this information to your terminal and hit Enter .

5) Open terminal in mac os from anywhere enter adb connect 192.168.2.134:5555 .

6) Finally you successfully connected to adb . it will show message like connected to 192.168.2.140:5555

I hope its help you ,Thank You !

I wrote a shell script which can let you debug an Android device via Wi-Fi.

Here is the code:

#!/usr/bin/env bash
#Notice: if unable to connect to [ip]:5555,
#try adb kill-server then try again.

adb shell ip route > addrs.txt
#Case 1:Nexus 7
#192.168.88.0/23 dev wlan0  proto kernel  scope link  src 192.168.89.48

#Case 2: Smartsian T1,Huawei C8813
#default via 192.168.88.1 dev eth0  metric 30
#8.8.8.8 via 192.168.88.1 dev eth0  metric 30
#114.114.114.114 via 192.168.88.1 dev eth0  metric 30
#192.168.88.0/23 dev eth0  proto kernel  scope link  src 192.168.89.152  metric 30
#192.168.88.1 dev eth0  scope link  metric 30

ip_addrs=$(awk {'if( NF >=9){print $9;}'} addrs.txt)

echo "the device ip address is $ip_addrs"

echo "connecting..."

rm addrs.txt

adb tcpip 5555

adb connect "$ip_addrs"

That is too much simple...

Step 1:

connect mobile to laptop (PC)
find adb path in Eclipse or Go Tast manager (<kbd>Ctrl</kbd> + <kbd>Shift</kbd> + <kbd>Esc</kbd>) -> process -> adb.exe -> right-click -> open file location -> copy the path of the open window (like D:\.....)

Step 2:

open cmd and change directory like C:, D:, E:, and G:
 1: C:\Users\UMT>D:
 2: D:\> cd (past path of adb) like (ANDROID eclipse\Eclipse Setup\adt-bundle-windows-x86_64-202\sdk\plat-form-tools) and press enter
 3: Then type `adb tcpip 5555`. Press <kbd>Enter</kbd> ... make sure your mobile connects to the PC

Step 3:

Open new cmd and same above, go to the adb directory and type
adb connect 192.168.x.x(device ip):5555
press enter now connect it.

Device IP address: Setting -> About phone -> Status -> IP address

1- For this I am considering you have already installed the latest version of Android studio. If not you can download it from here.

2 - You can set the platform tools path in environment variable (optional).

3 - Make sure your device and pc connected to same network.

• plug in the data cable from pc to device.

• Now, type adb tcpip 5555

• remove data cable.

• Then type adb connect 192.168.43.95

• here 5555 is the port number and 192.168.43.95 is the ip address of the mobile device you can get id address from the mobile settings .

• Then go to About device and go to status you can see the ip address of the device.

• You can connect multiple device from different ports which can give ease in development.

• Or you can go to this link for brief description with screenshots. http://blogssolutions.co.in/connect-your-android-phone-wirelessly-by-adb

If you want to enable wireless adb on the device without connecting with a USB cable at all (root required):

1. Install a terminal app on the device (like Android Terminal Emulator) Type the following
2. su
3. setprop service.adb.tcp.port 5555
4. stop adbd
5. start adbd

Since you already have the terminal opened, you can find the IP address of the device:

ip addr show

Then in your debugging environment run command:

adb connect ip.of.the.device

This will make the device to be listed as any other emulators you might have. Note that the TCP will stay opened until you reset the device. You might also want to install a Wi-Fi Keep Alive app if you often experience disconnects.

Remember to close the TCP when connecting to public networks if you want to feel safe. You can do the following or simply restart the device:

1. su
2. setprop service.adb.tcp.port -1
3. stop adbd
4. start adbd

For all , this , there exists a better method (EASIEST METHOD) :

1 ) A plugin for Android studio exits , called Android wifi ADB

2) Go to file -> settings -> Plugins -> Browse Repositories

3) Look for Android WiFi ADB , click on INSTALL , and then restart on prompt

4) You will see a new icon , which is your new plugin .

Now to make this work :

5) Go to your phone's developer option and enable DEBUGGING (must)

6) Also enable , ALLOW DEBUG OVER TCP/NETWORK

7) Attach your phone via USB , and make sure , both phone and your pc/laptop are connected to the same network (either hotspot or wifi)

8) CLICK ON THE NEW ICON (ie your ANDROID Wifi ABD)

9) Your phone get's detected and get's connected over wifi/hotspot , and hence now you may disconnect the usb . This is a one time process , hence you may not need to keep phone connected over usb .

This will save your phone from irregular charges and also , a remedy for short length usb cables .

1. In Device Settigs-> "Developer options" -> "Revoke USB debugging authorizations".
2. Connect the device via USB and make sure debugging is working.
3. adb tcpip 5555
4. adb connect <DEVICE_IP_ADDRESS>:5555
5. Disconnect USB
6. adb devices

Install plugin Android WiFi ADB

Download and install Android WiFi ADB directly from Android Studio:

File > Settings->Plugins->Browse Repositories-> Android WiFi ADB ->Install ->Connect with cable for first time -> Click on "Connect" -> Now remove cable and start doing debug/run.

Check ss for your reference :

Connect the device via USB and make sure debugging is working. these steps are taken if you already have installed adb and set it's path in environment varialbe

1. open cmd and type the following
2. adb tcpip 5555
3. find the IP address with adb shell ip route
4. adb connect DEVICE_IP_ADDRESS:5555
5. Disconnect USB and proceed with wireless debugging.

first you shold connect your device with usb to pc after that run cmd and drag and drop adb.exe that is in sdk/platform-tools path and write below code :

    ....\Sdk\platform-tools\adb.exe devices

    .....\Sdk\platform-tools\adb.exe tcpip 5555

    .....\Sdk\platform-tools\adb.exe connect Ip address:5555

Best and super easy way to do this is:-

1. Make a batch file :-

adb devices
