.NET for Android error XA0003

Issue

This error means the value for android:versionCode in the AndroidManifest.xml file is not an integer value.

Google requires that the value be an integer within the range of 0 to 2100000000. See https://developer.android.com/studio/publish/versioning for more details.

Solution

Correct the android:versionCode in the AndroidManifest.xml to be an integer in the range of 0 to 2100000000.
