The idea is to set the environment variable ADB (which is read by scrcpy).

In a shell (typically on linux), you can set the variable for a single command:

VAR=value command

On Windows, you can set it globally in Windows preferenced, but you can also set it locally:

set VAR=value
command

So:

set ADB=C:\path\to\adb.exe
scrcpy

Since I'm using linux, my solution was similar to yours. I added the following line into my .profile: export ADB=$HOME/Android/Sdk/platform-tools/adb

@rom1v please add new adb in new version

[Ragner16]

1.Ensure there is no other copy of abd in your machine. 2.Add environment variable adb.exe and give path as value

3. Run command prompt as admin

It worked for me this way!

2. adb kill-server
3. ps ax | grep adb 12290 ? S 0:00 /home/usuario/Android/Sdk/platform-tools/adb devices -l 12291 ? Ssl 0:00 adb -L tcp:5037 fork-server server --reply-fd 7 12332 pts/1 S+ 0:00 grep --color=auto adb
4. cd /home/usuario/Android/Sdk/platform-tools
5. mv adb adbxxx
6. ln -s /usr/lib/android-sdk/platform-tools/adb adb
7. Restart Android Studio

thanks for you , it worked will

OKEY Just locate the android studio build tools folder in settings of Genymotion , to use the same adb version meaning both the Android studio and the Genymotion emulator, so go for settings in genymotion under setting expand adb then set the folder location.

Got a quick way to do it First sudo rm /usr/bin/adb

Then sudo ln -s /home/{{username}}/Android/Sdk/platform-tools/adb /usr/bin/adb Fastest way to fix the issue

rom1v commented on 30 Jul 2019 Oh, but your problem is the reverse:

adb server version (40) doesn't match this client (41);

You correctly uses v41, but some app on your computer executes adb commands with adb v40. You must find this app and stop it 😉

In my case, I had AirDroid App installed and it uses adb. That's why I had the bug. Simply uninstall it and everything is working!

[Nikzed]

Just to point out how you should add adb variable to your PATH

[Nikzed]

Hi all, replace 3 files in "scrcpy" folder by their version in "platform-tools" maybe work.

I hope this will be useful !!!

it helps!
