System.Xml.dll.so not found

Hi all,

I have created a Xamarin.Forms location based app using Xamarin.Forms Maps.

It runs on iOS perfectly (just publishing it to the Apple Store)

Now I tried to make an Android version.

Included Google Play Services, get an Google API key, all the stuff, added necessary other components, set Java Heap Size.

The app rebuilds (only With Linker set to "Don't link) and deploys to my physical device or the the new Xamarin Android Player (Google Play Service installed)

Then the app is started on the physical device or on the Android simulator.

During the start up, THIS error occurs:

[Mono] AOT module 'System.Xml.dll.so' not found: Cannot load library: load_library[1093]: 
Library '/data/data/PickMeUp.Droid/lib/System.Xml.dll.so' not found

What can I do ? What did I wrong ?

Any ideas ?

(also after this error on the Xamarin Android Player this error comes also: [GooglePlayServicesUtil] Google Play Store is missing.)

Best

Marco
