Xap file not updating
The Xamarin Android Player is a great way to test your Android applications quickly and easily.
One thing that is not included directly is support for Google Play Services.
It is assumed you already have the emulator installed and have download one or more of the supported images.
This is a moment of rejoice for the owners of devices having no expansion slots (like Lumia 1020, 925, 920; etc) as now even they can enjoy downloading apps to PC and then install over to the phone.
This means that several APIs, including support for maps, are not supported by the emulator.
