Lot's of these are showing up in the Android logs.

Here's a possible fix:

I think we need to close the reader and the connection it looks like. This is NOT best practice for SQLServer, so we should only implement that in the SQLLite provider.

The .NET SqlConnectionProvider does its own internal connection pooling / optimization that is why you shouldn't close it yourself, but rather use Using{ } statements.
