I have an Xamarin project (On a Mac) that I'm working on. Up until today I was able to Launch it under debug, it would deploy the app and start it up attached so I could hit break points on the device. If I do this in an emulator, things work fine. So when I run in Debug on Android, it deploys, I get no errors or messages that indicate an issue, but it just stops and is no longer running. So what I've done I've uninstalled and re-installed Visual Studio, no change I've tried on multiple devices, with different OS versions I've reset my project to be the same as others on the team, they have no issue I've verified that the same project works fine on my Windows machine. I've verified that I can run a Release version with no problem, I hit run, it deploys and launches the app just fine. I can deply the iOS version in an emulator with no problems. I've verified that if I set Debug Information to Full in the Release project, I have the same issue. I've rebooted the device, the Mac, uninstalled the app on the device, it doesn't matter. I'm at a loss, any help would be appreciated.

Xamarin Debugging on Android Device not working

I have an Xamarin project (On a Mac) that I'm working on. Up until today I was able to Launch it under debug, it would deploy the app and start it up attached so I could hit break points on the device. If I do this in an emulator, things work fine.

So when I run in Debug on Android, it deploys, I get no errors or messages that indicate an issue, but it just stops and is no longer running.

So what I've done

I've uninstalled and re-installed Visual Studio, no change
I've tried on multiple devices, with different OS versions
I've reset my project to be the same as others on the team, they have no issue
I've verified that the same project works fine on my Windows machine.
I've verified that I can run a Release version with no problem, I hit run, it deploys and launches the app just fine.
I can deply the iOS version in an emulator with no problems.
I've verified that if I set Debug Information to Full in the Release project, I have the same issue.
I've rebooted the device, the Mac, uninstalled the app on the device, it doesn't matter.

I'm at a loss, any help would be appreciated.

I know it's very late answer but I had same problem and could solve it so may be it could be helpful for over people facing same problem.

Android csproj file must be located two levels lower than the .sln file. Android will disconnect when debugging if it is located in another location.

For example:

C:\Projects\Mobile\My.Xamarin.sln C:\Projects\Mobile\My.Xamarin\My.Xamarin.Android\My.Xamarin.Android.csproj

Well, there are a couple of things that connecting and deploying your app require, including setting the configuration and making sure you have the ADB installed correctly. You can check on Mac by following these steps to install Chrome and DevTools.

Another user suggested(in the comments under question): "I would suggest trying to delete the Mono Shared Runtime and any Xamarin Android API-XX Support from the installed apps" on your targeted device.

These are the docs on Configuration Management in Xamarin on Microsoft.com
