If you are using the following configuration under Xamarin.Android, you may experience an issue (“Compile to dalvik: Unexpected top-level error“) which prevents your build from succeeding:

• Xamarin.Forms
• Xamarin.Forms.Maps
• Deploying to release

Resolving the issue

To resolve this issue, simply do the following:

1. Right-click on your Xamarin.Android project
2. Select “Properties”
3. Open “Android Options” => “Advanced”
4. Set “Java Max Heap Size” to 1G

Now, you should be able to build your Xamarin.Android project in release mode once more.
