c# - Xamarin Forms (Android): OnCreate bundle is null -


i have android project, , wish store api keys in android manifest file. read them, can read bundle comes through in oncreate override in mainactivity class: viz

type mainactivity () =     inherit formsapplicationactivity()     static let [<literal>] myapikey = "my-api-key"     override this.oncreate (bundle) =         base.oncreate(bundle)         let createviewmodel() = new photosetviewmodel() :> iroutableviewmodel         appdomain.currentdomain.unhandledexception.addhandler(unhandledexceptioneventhandler(appexceptions.processexception))         forms.init(this, bundle)         xamarin.formsmaps.init(this, bundle)         // read api key i've stored in androidmanifest.xml         let platform = new droidplatform(bundle.getstring(myapikey)) :> icustomplatform         let app = new app<icustomplatform>(platform, new uicontext(this), createviewmodel)         app.init()         base.loadapplication app

there 1 small problem. bundle null. happening in of projects, in both c# , f# implementations.

i'm using xamarin.forms nuget package, version 2.3.4.224.

instead of trying use bundle argument, possible retrieve metadata follows:

let metadata = packagemanager.getapplicationinfo(packagename, packageinfoflags.metadata).metadata let platform = new droidplatform(metadata.getstring(myapikey)) :> icustomplatform
