Fire Beta: Unable to run template Android Application (Swift)

Ok, so I have updated Fire.
I have started from scratch a new Android Application project in the current solution.
Now I can run this kind of template project.

The console prints

Installing org.me.androidsilversampleapp
Calling adb -s 0a21584f install -r "/Users/admin/Projects/MusiXmatch/MXMPortableNETLib/Samples/AndroidSilverSampleApp/./bin/Release/AndroidSilverSampleApp.apk"

I had to set the configuration to Release for this target.

and then it freezes for a while and then:

The process failed to start with the following error:

Starting: Intent { cmp=org.me.androidsilversampleapp/.MainActivity }

I have just created a project without any change so I have a basic

public class MainActivity: Activity {

	public override func onCreate(savedInstanceState: Bundle!) {
		super.onCreate(savedInstanceState)
		ContentView = R.layout.main
	}
}

If I open Android Monitor from AndroidStudio, I can see:

02-29 11:03:27.430 605-1260/? I/ActivityManager: Force stopping org.me.androidsilversampleapp appid=10086 user=-1: set debug app

02-29 11:03:27.511 8059-8059/? W/ActivityThread: Application org.me.androidsilversampleapp is waiting for the debugger on port 8100...

as it was likely waiting for debugger (even if the target was set to Release).

In Settings the CrossBox Device ID is still unexpected value.

If I try to set to Debug configuration I get a “unable to deploy” error instead, after freezing and I can see on the Nexus 7 a alert entitled Waiting for Debugger.
