Unable to run dotnet-trace collect

[DavidM29]

Description

I am trying to trace an Android App(Uno Platform) on an emulator, I have followed the steps in this documentation as well as in this video and I always get this error when executing dotnet-trace collect:

Adding @lateralusX for thoughts

[DavidM29]

I will add that this happens only when trying to trace the app on an emulator, not on a device.

[lateralusX]

@DavidM29, could you run dsrouter using verbose logging and paste the log into this issue? Just add -v debug to the command line when running:

dotnet-dsrouter android-emu -v debug

[DavidM29]

Hello @lateralusX, sorry for the late response.
I had multiple emulators and I think that was the problem, after I left only one emulator and disconnected the physical device I was able to successfully trace the app.
