Basic Usage

Command syntax

adb basic syntax of the command is as follows:

adb [-d|-e|-s <serialNumber>] <command>

If only one device / emulator connection, you can omit the [-d | -e | -s <serialNumber>] this part, the direct use adb <command>.

Targeting equipment for command

If you have more than one device / emulator connection, you need to specify the target device for the command.

Parameter	Meaning
-d	Specifies currently the only Android device USB connector as the command target
-e	Specify currently the only goal for the command to run the simulator
-s <SerialNumber>	Specifies the device number corresponding serialNumber / simulator command target

In the case of multiple devices / simulators are connected to the more common -s <serialNumber> parameters, serialNumber can be obtained through adb devices command. Such as:

$ adb devices

List of devices attached
cf264b8f	device
emulator-5554	device

Output in the cf264b8f and emulator-5554 is serialNumber. For example, this time I want to specify cf264b8f this equipment to run the adb command to take a screen resolution:

adb -s cf264b8f shell wm size

Encountered multiple devices / simulators use the case of these parameters for the command to specify the target device, hereinafter to simplify the description will not be repeated.

Start/Stop

Start adb server command:

adb start-server

(Generally no need to manually execute this command, when you run the command adb adb server if found does not start automatically from the transfer.)

Stop adb server command:

adb kill-server

View adb version

command:

adb version

Sample output:

Android Debug Bridge version 1.0.36
Revision 8f855a3d9b35-android

Run adbd as root

The operating principle is adb adb server daemon and the phone side PC side adbd establish a connection, then the PC side adb client via adb server forward command parsing after running adbd receive commands.

So if adbd ordinary rights to perform some require root privileges to execute the command can not be directly used adb xxx execution. Then you can then execute the command adb shell after su, but also allows adbd root privileges to perform this high privilege can execute arbitrary commands.

command:

adb root

Normal output:

restarting adbd as root

Now run adb shell, take a look at the command line prompt is not turned into a #?

After some phone root can not let adbd by adb root execute commands with root privileges, some models such as Samsung, will be prompted to adbd can not run as root in production builds, then you can install adbd Insecure, then adb root try.

Accordingly, if you want to restore adbd non-root privileges, you can use adb unroot command.

Designated adb server network port

command:

adb -P <port> start-server

The default port is 5037.

Device connection management

Inquiries connected device / simulator

command:

adb devices

Example output:

List of devices attached
cf264b8f	device
emulator-5554	device

Output format is [serialNumber] [state], serialNumber that is, we often say that the SN, state the following categories:

• Offline - indicates that the device is not connected to the success or unresponsive.

• Device - device is connected. Note that this state does not identify the Android system has been fully activated and operational in the device during startup device instance can be connected to the adb, but after boot the system before it becomes operational.

• No device - no device / emulator connection.

The output shows the current connected the two devices / simulators, cf264b8f and emulator-5554 are they SN. As can be seen from the emulator-5554 name it is an Android emulator.

Common alarm output:

1. No device / emulator connection is successful.

   List of devices attached
   

2. The device / emulator is not connected to adb or unresponsive.

   List of devices attached
   cf264b8f	offline
   

USB connection

USB connection normal use adb by the need to ensure that:

1. Hardware status is normal.

   Including Android devices in the normal power state, USB cable and interface intact.

Developer Options 2. Android devices and USB debugging mode is on.

You can go to the "Settings" - "Developer options" - "Android Debug" view.

If you can not find the developer options in the settings, it needs to make it through an egg is displayed: In the "Settings" - "About phone" continuous click "version number" 7 times.

3. The device driver is normal.

   It seems to worry about the Linux and Mac OS X, the Windows likely to be encountered in the case of the need to install drivers, this can be confirmed right "Computer" - "Properties", the "Device Manager" in view on related equipment Is there a yellow exclamation point or question mark, if not explain the driving state has been good. Otherwise, you can download a mobile assistant class program to install the driver first.

4. Status after confirmation via USB cable connected computers and devices.

   adb devices
   

   If you can see

   xxxxxx device
   

   Description Connection successful.

Wireless connection (need to use the USB cable)

In addition to the USB connection to the computer to use adb, can also be a wireless connection - although the connection process is also step using USB needs, but after a successful connection to your device can get rid of the limit of the USB cable within a certain range it !

Steps:

1. Connect Android device to run adb computer connected to the same local area network, such as connected to the same WiFi.

2. The device connected to the computer via a USB cable.

   Make sure the connection is successful (you can run adb devices see if you can list the device).

3. Allow the device listens on port 5555 TCP / IP connections:

   adb tcpip 5555
   

4. Disconnect the USB connection.

5. Find the IP address of the device.

   Generally the 'Settings' in - "About phone" - "state information" - "IP address" is found, you can also use the following in the View device information - IP address a Lane method adb command.

6. Connect the device via IP address.

   adb connect <device-ip-address>
   

   Here <device-ip-address> is the IP address of the device found in the previous step.

7. Confirm the connection status.

   adb devices
   

   If you can see

   <device-ip-address>:5555 device
   

   Description Connection successful.

If you can not connect, verify that Android devices and the computer is connected to the same WiFi, then execute adb connect <device-ip-address> that step again;

If that does not work, by adb kill-server restart the adb and then try it all over again.

The wireless connection

command:

adb disconnect <device-ip-address>

Wireless connection (without using the USB cable)

Note: You need root privileges.

On a "wireless connection (need to use USB cable)" method is described in official documents, need the help of a USB cable to enable the wireless connection.

Since we want to achieve a wireless connection, it can all step down are wireless it? The answer is energy.

1. Install a terminal emulator on the Android device.

   Equipment already installed you can skip this step. Terminal emulator download address I use is: Terminal Emulator for Android Downloads

2. To run the Android device and computer adb is connected to the same local area network, such as connected to the same WiFi.

3. Open a terminal emulator on your Android device, in which run the command sequence:

   su
   setprop service.adb.tcp.port 5555
   

4. Find the IP address of the Android device.

   Generally the 'Settings' in - "About phone" - "state information" - "IP address" is found, you can also use the following in the View device information - IP address a Lane method adb command.

5. Connect Android device on a computer via adb and IP addresses.

   adb connect <device-ip-address>
   

   Here <device-ip-address> is the IP address of the device found in the previous step.

   If you can see connected to <device-ip-address>: 5555 such output indicates a successful connection.

Application Management

Check the list of

Check the list of basic commands format

adb shell pm list packages [-f] [-d] [-e] [-s] [-3] [-i] [-u] [--user USER_ID] [FILTER]

That is the basis of adb shell pm list packages can add some parameters on the filter to view different lists, supports filtering parameters are as follows:

Parameter	display list
No	all applications
-f	Display apk file application association
-d	Show only applications disabled
-e	Show only enabled applications
-s	Display only System
-3	Show only third-party application
-i	Display applications installer
-u	Contains uninstall applications
<FILTER>	package name contains <FILTER> strings

All applications

command:

adb shell pm list packages

Example output:

package:com.example.android.livecubes
package:com.android.providers.telephony
package:com.google.android.googlequicksearchbox
package:com.android.providers.calendar
package:com.android.providers.media
package:com.android.protips
package:com.android.documentsui
package:com.android.gallery
package:com.android.externalstorage
...
// other packages here
...

system applications

command:

adb shell pm list packages -s

third-party usage

command:

adb shell pm list packages -3

Application package name contains a string

For example, to view a list of package names that contain the string mazhuang applications, order:

adb shell pm list packages mazhuang

Of course, you can also use grep to filter:

adb shell pm list packages | grep mazhuang

Install APK

Format:

adb install [-lrtsdg] <path_to_apk>

parameter:

Adb install may be followed by some optional parameters to control the behavior of the installation APK, available parameters and their meanings are as follows:

Parameter	Meaning
-l	Will be applied to protect the installation directory / mnt / asec
-r	Allowed to cover the installation
-t	Allowed to install application specified in AndroidManifest.xml android: testOnly =" true " Application
-s	Install apps to sdcard
-d	Downgrade coverage allows installation
-g	Grant all runtime permissions

After you run the command to see if similar to the following output (status is Success) represents the installation was successful:

[100%] /data/local/tmp/1.apk
	pkg: /data/local/tmp/1.apk
Success

The above is the output of adb current latest version v1.0.36, it will push apk file to display the progress of the percentage of mobile phones.

Using older versions of adb output is this:

12040 KB/s (22205609 bytes in 1.801s)
        pkg: /data/local/tmp/SogouInput_android_v8.3_sweb.apk
Success

If the status is Failure said installation failure, such as:

[100%] /data/local/tmp/map-20160831.apk
        pkg: /data/local/tmp/map-20160831.apk

Adb install internal principle Introduction

Adb install actually three steps:

1. push apk files to / data / local / tmp.

2. Call pm install installation.

3. Delete the corresponding apk file / data / local / tmp under.

Therefore, when necessary, according to this step, manually step through the installation process.

Uninstalling

command:

adb uninstall [-k] <packagename>

<Packagename> represents the application package name, -k optional parameter indicates uninstall the application but keep the data and cache directories.

Command Example:

adb uninstall com.qihoo360.mobilesafe

Uninstall represents 360 mobile guards.

Clear app cache data

command:

adb shell pm clear <packagename>

<Packagename> represents the name of the application package, the effect of this command is equivalent to the application information in the settings screen, click the "Clear Cache" and "Clear data."

Command Example:

adb shell pm clear com.qihoo360.mobilesafe

360 mobile guards to clear the data and cache.

View Reception Activity

command:

adb shell dumpsys activity activities | grep mFocusedActivity

Example output:

mFocusedActivity: ActivityRecord{8079d7e u0 com.cyanogenmod.trebuchet/com.android.launcher3.Launcher t42}

Where com.cyanogenmod.trebuchet / com.android.launcher3.Launcher is currently in the foreground Activity.

Applications to interact with

Primarily using am <command> command commonly used <command> as follows:

Command	use
Start [options] <INTENT>	Start <INTENT> specified Activity
Startservice [options] <INTENT>	Start <INTENT> designated Service
Broadcast [options] <INTENT>	Send <INTENT> designated broadcast
Force-stop <packagename>	stop <packagename> related processes

<INTENT> very flexible parameters, and write Android program code corresponding to the Intent.

Options for determining intent objects as follows:

Parameter	Meaning
-a <ACTION>	specified action, such as android.intent.action.VIEW
-c <CATEGORY>	specify a category, such as android.intent.category.APP_CONTACTS
-n <COMPONENT>	specify the full component name, which is used to explicitly specify the start Activity, such as com.example.app / .ExampleActivity

<INTENT> can bring in data, like Bundle write code like:

Parameter	Meaning
--esn <EXTRA_KEY>	null value (only key name)
`-e	--es <EXTRA_KEY> <EXTRA_STRING_VALUE>`
--ez <EXTRA_KEY> <EXTRA_BOOLEAN_VALUE>	boolean value
--ei <EXTRA_KEY> <EXTRA_INT_VALUE>	integer value
--el <EXTRA_KEY> <EXTRA_LONG_VALUE>	long value
--ef <EXTRA_KEY> <EXTRA_FLOAT_VALUE>	float value
--eu <EXTRA_KEY> <EXTRA_URI_VALUE>	URI
--ecn <EXTRA_KEY> <EXTRA_COMPONENT_NAME_VALUE>	component name
--eia <EXTRA_KEY> <EXTRA_INT_VALUE> [, <EXTRA_INT_VALUE ...]	integer array
--ela <EXTRA_KEY> <EXTRA_LONG_VALUE> [, <EXTRA_LONG_VALUE ...]	long array

Transferred from Activity

Format:

adb shell am start [options] <INTENT>

E.g:

adb shell am start -n com.tencent.mm/.ui.LauncherUI

It represents transfer from the micro-channel main interface.

adb shell am start -n org.mazhuang.boottimemeasure/.MainActivity --es "toast" "hello, world"

Expressed from the transfer org.mazhuang.boottimemeasure / .MainActivity key data string and pass it to toast - hello, world.

Transferred from the Service

Format:

adb shell am startservice [options] <INTENT>

E.g:

adb shell am startservice -n com.tencent.mm/.plugin.accountsync.model.AccountAuthenticatorService

Service represents a transfer from micro-letter.

Transmits broadcast

Format:

adb shell am broadcast [options] <INTENT>

All components can be broadcast to be broadcast only to the specified component.

For example, all of the components to broadcast BOOT_COMPLETED:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED

As another example, only to org.mazhuang.boottimemeasure / .BootCompletedReceiver broadcast BOOT_COMPLETED:

adb shell am broadcast -a android.intent.action.BOOT_COMPLETED -n org.mazhuang.boottimemeasure/.BootCompletedReceiver

Such usage is very practical in the test, such as a broadcast scenes difficult to manufacture, can be considered to transmit broadcast in this way.

Both predefined broadcast transmission system can also send a custom broadcast. The following is part of the normal pre-defined radio and Trigger timing:

Action	trigger timing
android.net.conn.CONNECTIVITY_CHANGE	Fi changes
android.intent.action.SCREEN_ON	screen lit
android.intent.action.SCREEN_OFF	screen off
android.intent.action.BATTERY_LOW	low battery, low battery prompt box will pop up
android.intent.action.BATTERY_OKAY	electricity restored
android.intent.action.BOOT_COMPLETED	equipment Booted
android.intent.action.DEVICE_STORAGE_LOW	storage space is running low
android.intent.action.DEVICE_STORAGE_OK	storage space recovery
android.intent.action.PACKAGE_ADDED	install a new application
android.net.wifi.STATE_CHANGE	WiFi connection status change
android.net.wifi.WIFI_STATE_CHANGED	WiFi state to the On / Off / Starting up / shutting down / Unknown
android.intent.action.BATTERY_CHANGED	battery level changes
android.intent.action.INPUT_METHOD_CHANGED	system input method changes
android.intent.action.ACTION_POWER_CONNECTED	external power connector
android.intent.action.ACTION_POWER_DISCONNECTED	disconnected from external power
android.intent.action.DREAMING_STARTED	system began Sleep
android.intent.action.DREAMING_STOPPED	system stops Sleep
android.intent.action.WALLPAPER_CHANGED	wallpaper changes
android.intent.action.HEADSET_PLUG	insert earphone
android.intent.action.MEDIA_UNMOUNTED	unload external media
android.intent.action.MEDIA_MOUNTED	mount external media
android.os.action.POWER_SAVE_MODE_CHANGED	power-saving mode is turned on

• (Above broadcast can be used to trigger adb) *

Forcibly stop the application

command:

adb shell am force-stop <packagename>

Command Example:

adb shell am force-stop com.qihoo360.mobilesafe

Stop all processes and services represents 360 security guards.

File Management

Copy files to the computer equipment in

command:

adb pull <file path on device> [directory on the computer]

The parameters on which the directory `` computer can be omitted, it defaults to the current directory.

example:

adb pull /sdcard/sr.mp4 ~/tmp/

• Tips: * file path on the device may need root privileges to access, if your equipment has been root, you can use the adb shell and su command to obtain root privileges adb shell Lane after the first cp / path / on / device / sdcard / filename copy files to sdcard, then adb pull / sdcard / filename / path / on / pc.

Copy computer files to the device

command:

adb push <file path on your computer> <equipment in the catalog>

example:

adb push ~/sr.mp4 /sdcard/

• Tips: * file on the path of ordinary privileges may not be directly written to the device if you have root too, can be adb push / path / on / pc / sdcard / filename, and then adb shell after su obtain root privileges adb shell inside, cp / sdcard / filename / path / on / device.

Analog Keys / inputs

In adb shell there is a very useful command called input, through which you can do some interesting things.

Complete help information input command is as follows:

Usage: input [<source>] <command> [<arg>...]

The sources are:
      mouse
      keyboard
      joystick
      touchnavigation
      touchpad
      trackball
      stylus
      dpad
      gesture
      touchscreen
      gamepad

The commands and default sources are:
      text <string> (Default: touchscreen)
      keyevent [--longpress] <key code number or name> ... (Default: keyboard)
      tap <x> <y> (Default: touchscreen)
      swipe <x1> <y1> <x2> <y2> [duration(ms)] (Default: touchscreen)
      press (Default: trackball)
      roll <dx> <dy> (Default: trackball)

Such as using adb shell input keyevent <keycode> command, different keycode to achieve different functions, keycode complete list see KeyEvent, I think the interesting part of the quote is as follows:

Keycode	Meaning
3	HOME button
4	return key
5	open dialing application
6	hang up
24	increase volume
25	Volume Down
26	Power button
27	taking pictures (in the camera application needs in)
64	Open Browser
82	menu button
85	Play / Pause
86	stop playing
87	play the next
88	played on a
122	Move the cursor to the beginning or top of the list
123	Move the cursor to the end of the line or bottom of the list
126	resume playing
127	pause play
164	Mute
176	Open the System Setup
187	switching applications
207	Open Contacts
208	Open calendar
209	Open Music
210	Open Calculator
220	Decrease screen brightness
221	Increase screen brightness
223	System Sleep
224	light up the screen
231	Open the voice assistant
276	If no wakelock allow the system to sleep

Here are some examples of the use of input command.

On / Off screen

It can be switched on and off by telling off the screen above the analog power button, but if you want to light up or clear off the screen, then you can use the following method.

Light up the screen:

adb shell input keyevent 224

Off screen:

adb shell input keyevent 223

Slide to unlock

If no password lock screen is unlocked by sliding gestures, so you can input swipe to unlock.

Command (parameter models Nexus 5, swipe up to unlock, for example):

adb shell input swipe 300 1000 300 500

3001000300 parameters represent 500` starting x coordinate of the start point y coordinate of the end point x coordinate y coordinate of the end point '.

Enter text

When the focus is in a text box, you can enter text by input command.

command:

adb shell input text hello

Hello now appear in the text box.

View Log

Log Android system is divided into two parts, the underlying Linux kernel log output to / proc / kmsg, Android's log output to / dev / log.

Android log

Format:

[adb] logcat [<option>] ... [<filter-spec>] ...

Common usage are listed below:

Filter the log by level

Android log divided into the following levels:

• V - Verbose (lowest output most)
• D - Debug
• I - Info
• W - Warning
• E - Error
• F - Fatal
• S - Silent (highest, what is not output)

Press a grade level and above filter log is the log output.

For example, the command:

adb logcat *:W

Will Warning, Error, Fatal and Silent log output.

Filter by tag and log level

For example, the command:

adb logcat ActivityManager:I MyApp:D *:S

Represents an output tag ActivityManager above the level of Info logs, Debug log output above the level of the tag MyApp, and other tag Silent level of log (ie, shield other tag logging).

Log format

You can use adb logcat -v <format> option specifies log output format.

Log supported by the following <format>:

• brief

  The default format. The format is:

  <priority>/<tag>(<pid>): <message>
  

  Example:

  D/HeadsetStateMachine( 1785): Disconnected process message: 10, size: 0
  

• process

  The format is:

  <priority>(<pid>) <message>
  

  Example:

  D( 1785) Disconnected process message: 10, size: 0  (HeadsetStateMachine)

adb shell dumpsys iphonesubinfo

Example output:

Phone Subscriber Info:
  Phone Type = GSM
  Device ID = 860955027785041

Device ID which is IMEI.

In Android 5.0 and above in the command output is empty, was acquired by other means (requires root privileges):

adb shell
su
service call iphonesubinfo 1

Example output:

Result: Parcel(
  0x00000000: 00000000 0000000f 00360038 00390030 '........8.6.0.9.'

The effective content is extracted from the inside of the IMEI, such as here is 860955027785041.

Reference: adb shell dumpsys iphonesubinfo not working since Android 5.0 Lollipop

Android system version

command:

adb shell getprop ro.build.version.release

Example output:

IP address

Every time you want to know the IP address of the device had the "Setting" - "About phone" - "state information" - "IP address" annoying, right? You can easily see via adb.

command:

adb shell ifconfig | grep Mask

Example output:

inet addr:10.130.245.230  Mask:255.255.255.252
inet addr:127.0.0.1  Mask:255.0.0.0

So it is 10.130.245.230 device IP address.

On some devices this command no output, if the device is attached to WiFi, you can use the following command to view the LAN IP:

adb shell ifconfig wlan0

Example output:

wlan0: ip 10.129.160.99 mask 255.255.240.0 flags [up broadcast running multicast]

or

wlan0     Link encap:UNSPEC
          inet addr:10.129.168.57  Bcast:10.129.175.255  Mask:255.255.240.0
          inet6 addr: fe80::66cc:2eff:fe68:b6b6/64 Scope: Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1

          TX packets:68215 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:3000
          RX bytes:116266821 TX bytes:8311736

If the above command still can not get the desired information, then you can try the following command (part of the system version is available):

adb shell netcfg

Example output:

Utility functions

Screenshots

command:

adb shell screencap -p /sdcard/sc.png

And then export the png file to your computer:

adb pull /sdcard/sc.png

You can use the adb shell screencap -h See help screencap command, here are two significant parameters and their meanings:

Parameter	Meaning
-p	Save the file in png format specified
-d Display-id	screenshots display the specified number (multiple screen display case next)

Found If you specify a file name can be omitted when the -p parameter to .png ending; otherwise you need to use the -p parameter. If you do not specify a file name, file contents screenshot will be directly output to stdout.

Recording Screen

Record screen are saved in mp4 format to / sdcard:

adb shell screenrecord /sdcard/filename.mp4

When you need to stop press Ctrl-C </ kbd>, the default recording time and maximum recording time is 180 seconds.

If you need to export to your computer:

adb pull /sdcard/filename.mp4

You can use the adb shell screenrecord --help See help screenrecord command, the following are common parameters and their meanings:

Parameter	Meaning
--size WIDTHxHEIGHT	dimensions of the video, such as 1280x720, default screen resolution.
--bit-Rate RATE	bit-rate video, the default is 4Mbps.
--time-Limit TIME	recording length, in seconds.
--verbose	Print more information.

Remount system partition as writable

Note: You need root privileges.

/system partitions are mounted read-only, but some operating systems such as Android to add commands to remove the need to bring their own application / system write operation, it is necessary to remount it read-write.

step:

1. Enter the shell and switch to the root user privileges.

   command:

   adb shell
   su
   

2. View the current partition mounted case.

   command:

   mount
   

   Example output:

   Find one of our concerns with the / system of the line:

   /dev/block/platform/msm_sdcc.1/by-name/system /system ext4 ro,seclabel,relatime,data=ordered 0 0
   

3. remount.

   command:

   mount -o remount,rw -t yaffs2 /dev/block/platform/msm_sdcc.1/by-name/system /system
   

   Here / dev / block / platform / msm_sdcc.1 / by-name / system is we get the file path from the output in the previous step.

If the output is not an error, then the operation is successful, you can file / system under wanted.

Check connection over WiFi password

Note: You need root privileges.

command:

adb shell
su
cat /data/misc/wifi/*.conf

Example output:

network={
	ssid="TP-LINK_9DFC"
	scan_ssid=1
	psk="123456789"
	key_mgmt=WPA-PSK
	group=CCMP TKIP
	auth_alg=OPEN
	sim_num=1
	priority=13893
}

network={
	ssid="TP-LINK_F11E"
	psk="987654321"
	key_mgmt=WPA-PSK
	sim_num=1
	priority=17293
}

Ssid we shall see in the WLAN settings in the name, psk the password, key_mgmt security encryption.

To set the system date and time

** Note: You need root privileges. **

command:

adb shell
su
date -s 20160823.131500

It said it would change the system date and time at 13:15:00 on August 23, 2016.

restart cellphone

command:

adb reboot

Detect whether the device is root

command:

adb shell
su

In this case the command line prompt is $ indicates no root privileges, is the # indicates root.

Monkey use stress testing

Monkey can generate pseudo-random event to simulate a user click, touch, gesture and other operations, you can program being developed random stress test.

Usage is simple:

adb shell monkey -p <packagename> -v 500

He told <packagename> specific application to send 500 pseudo-random events.

Monkey in detail with reference to the use of official document.

On / off WiFi

** Note: You need root privileges. **

Sometimes the need to control the device WiFi mode, you can use the following command to complete.

Open WiFi:

adb root
adb shell svc wifi enable

Close WiFi:

adb root
adb shell svc wifi disable

If successfully implemented, the output is empty; if not get root privileges to execute this command will fail, output Killed.

    -m num  How many processes displays up
    -n num refresh how many times
    -d num refresh interval (in seconds, default value of 5)
    -s col sorted by a column (available col value: cpu, vss, rss, thr)
    -t display thread information
    -h displays help documentation

common problem

Start adb server failure

Error message

error: protocol fault (couldn't read status): No error

Possible Causes

adb server process wants to use 5037 port is occupied.

solution

Found consumes process 5037 port, and then terminate it. In Windows, for example:

netstat -ano | findstr LISTENING

...
TCP    0.0.0.0:5037           0.0.0.0:0              LISTENING       1548
...

1548 Here is the process ID, the process ends with the command:

taskkill /PID 1548

Then start adb no problem.
