Attach debugger to Android game on Mac

In the past I've been able to run a game on device, set breakpoints in MonoDevelop, and have the device pause when it hits my breakpoint. The only thing is that this was back when I worked on a Windows machine.

I'm now working on a Mac, and I can't seem to get the same thing to work anymore. I know that Visual Studio on Mac is essentially a skin of Mono, so, correct me if I'm wrong, I assume the Attach to Process option should work the same way. I do see my device in the list (see attached image). However, when I hit "Attach", it says "Debugger operation failed" and "Operation is not valid due to the current state of the object".

I have Development Build, Autoconnect Profiler, and Script Debugging enabled in Build Settings. Am I missing something?

 

Hi @yuch3n, sorry for this issue. Could you please give us the VS 4 Mac version you are currently using ? It feels like something we already fixed.

Regards

Visual Studio for Mac Community Edition, Version 8.0.4 (build 0)

 

Ok thanks for confirming!

Edit: tried on my mac, I do not repro with 8.0.4. I'm able to attach and debug a project.

Could you repro and send us your logs (Help -> Open Log Directory) here:
vstusp [at] microsoft [dot] com

I've sent the logs (a cut version with only the crash and some other things), but I'll post here just in case.

Hi @yuch3n , @sailro , I'm just wondering if you made any progress here? I'm also getting the same issue and feel like how the cat looks in yuch3n's profile at the moment..

 

@IMD Hahaha I love this cat meme

But yes, when I emailed VS Tools they told me to use this workaround:
"In Tools for Unity -> Debugging, change the debugger engine from VSTU to Mono. Let us know if that works around the issue."



It worked for me. I haven't heard back from them about whether the issue was solved yet though.

 

Hello,

Yes, we solved the issue for VS4Mac 8.2.x series. So you should re-use the VSTU debugger that is tailored for Unity.
Are you still hitting the issue with an updated VS4Mac or are you using an old version ?

This issue still persist even I am using latest version of VS.
VS version: 8.3.10 (Mac Community edition)
