android - Problems with adb.exe - AdbHostServer.cpp:93: Unable to connect to adb daemon on port: 5037

Question

I have a problem with adb.exe of Android Studio 3.4.

When I run the emulator, I get this error:

Emulator: emulator: ERROR: AdbHostServer.cpp:93: Unable to connect to adb daemon on port: 5037

I opened a terminal with the rute of the adb.exe: C:UsersChristianAppDataLocalAndroidSdkplatform-tools

And here I tried with adb kill-server and then adb start-server and I get this:

*daemon not running; starting now at tcp:5037
*daemon started successfully

When i run again the same error appears, i get this in terminal with the command adb devices:

List of devices attached
emulator-5554   offline

I emulate Nexus 5X API 28 with System Image: Pie 28 x86 Android 9.0.

I download the last version of abd.exe in for Windows

I also reinstalled the Android Studio and the emulator, but the error still appears.

How can I solve that?

You need to first run adb start-server and then run emulator -avd <avd_name>
