Trouble deploying release version of Xamarin.Android app

Question

I'm getting the following error when the app finishes installing on the emulator using Xamarin Release run tool.

GREF GC Threshold: 1800

Unhandled Exception:
System.Net.WebException: Error: NameResolutionFailure
  at System.Net.HttpWebRequest.EndGetResponse (IAsyncResult asyncResult) [0x00000] in <filename unknown>:0 
  at CallRestService.Activity1.<OnCreate>m__0 (IAsyncResult ar) [0x00000] in <filename unknown>:0 
  at System.Net.WebAsyncResult.CB (System.Object unused) [0x00000] in <filename unknown>:0 

The emulator is running Android 2.3.3, and the Debug build ran from Xamarin compiler works just fine.

Any hint on why this is happening and how to solve this problem?

Answer 1

Had the same issue. Solved by adding <uses-permission android:name="android.permission.INTERNET" /> to the manifest.
