If your device runs Android 8 or below, set the `server_debugger_method` to
`old` in addition:
```bash
meson x -Dserver_debugger=true -Dserver_debugger_method=old
# or, if x is already configured
meson configure x -Dserver_debugger=true -Dserver_debugger_method=old
```
Then recompile.
When you start scrcpy, it will start a debugger on port 5005 on the device.
