Xamarin Application Could Not Be Started

Encounter this error today while using Xamarin.

The application could not be started. Ensure that the application has been installed to the target device and has a launchable activity (MainLauncher = true). Additionally, check Build -> Configuration Manager to ensure this project is set to Deploy for this configuration.



The setup was as follow: Using the Xamarin plugin for Microsoft Visual Studio 2012 in Windows 8, debugging on a Galaxy Nexus. The problem started when switching to a Nexus 7. Problem stayed when going back to the mobile, which doesn’t make much sense as nothing else has changed manually.

However, to solve it, open Build -> Configuration Manager



Check Deploy on your project. Now Run your application again and the issue should have been resolved.
