Epson ePOS SDK for Android (Xamarin) missing constants
问题 We are trying to updgrade the SDK of epson, which is deprecated since a long while. We were using the old ePOS-Print SDK (com.epson.eposprint) package and we began having problems with it, so we rightly decided to migrate to the current one, Epson ePOS SDK for Android (com.epson.epos2). We are using Visual Studio Xamarin. We followed the migration document included in the SDK. Replaced most of the code. But, it seems that either Xamarin has problem the java bindings or something is missing,
