I want to connect to an android phone using adb over WIFI. When I do (either by using WIFI Adb or the buildin ADB over Network in android) I get:
$ adb connect 192.168.122.203
failed to authenticate to 192.168.122.203:5555
and adb devices shows the same result:
List of devices attached
192.168.122.203:5555 unauthorized
The solution I find everywhere is: Connect the device via USB and authorize the PC, then connect via WIFI.
Unfortunately I cannot do that, because:
I have installed android-x86 (newest version is android 7.1.2) inside libvrt-manager (KVM). I have no Idea how I would connect this virtual machine with android via USB to my PC.
So is there a way to authorize a PC for adb usage without every connecting the android Device via USB?
True wireless adb is available only on Android version 11 and above. All version below you have to connect the USB cable and forward the tcp/ip port 5555 and then connect this is called adb over WiFi.
More details are here
I would recommend using a Android 11 emulator if possible if you can't have a USB connection
