Xamarin Android (Visual Studio 2015) Could not connect to the debugger
Solution 1
I had same issue and I was able to connect debugger by following this:
http://dotnetbyexample.blogspot.cz/2016/02/fix-for-could-not-connect-to-debugger.html
In short:
Disable "Use fast deployment (debug mode only)" in Android project -> Properties -> Android options -> Packaging
Enable "Migrate to a physical computer with a different processor version" in Hyper-V manager go to VM -> Settings -> Processor -> Compatibility
Solution 2
For me, this turns out to be an issue of DELL laptop running on Windows 10, after I rolled back to Windows 8.1, it works fine now
Solution 3
Error accepting stdout and stderr (127.0.0.1:8896) Address already in use
This has been reported to Xamarin as Bug 34476.

I have a problem with the android debugger (Visual Studio 2015) as it always stops immediately after starting debug (it works just fine without debugging), I had my machine reset and reinstalled Visual Studio 2015 but it does not help.
Here is the log from logcat: monodroid-debug Error accepting stdout and stderr (127.0.0.1:8896) Address already in use
Here is the log from Xamarin log:
Mono.Debugging.Soft.ConnectionException: Could not connect to the debugger. ---> Mono.Debugger.Soft.VMDisconnectedException: Exception of type 'Mono.Debugger.Soft.VMDisconnectedException' was thrown.

Any help is much appreciated!
