Hi James! I have the same issue (CrossMedia.Current.TakePhotoAsync throw Java.Lang.NullPointerException: Attempt to invoke virtual method ‘android.content.res.XmlResourceParser android.content.pm.ProviderInfo.loadXmlMetaData(android.content.pm.PackageManager, java.lang.String)’ on a null object reference), so I create small sample project that demonstrates it: https://bitbucket.org/nik_podakov/mediapluginsample/src
