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

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.

python - ValueError: No axis named 1 for object type <class 'pandas.core.series.Series'> -

i´m new programming. i´m trying use scipy minimize, had several issues , gotten through of them. right code, i'm not understanding why i´m getting error. par_opt = so.minimize(fun=fun_obj, x0=par_ini, method='nelder-mead', args=[series_pt_cal, dt, series_caudal_cal]) not enough info given op, somewhere in code it's specified operate data frame column (axis=1) on object pandas series. if code typically works occasional gives errors, check degenerative cases data frame may have 1 row. pandas has nasty habit of guessing want -- may decide reduce 1-row data frame series (e.g., apply() function; can disable using reduce=false in there). add line of code check object isinstance(df, pd.dataframe) or else convert offending pandas series data frame, s.to_frame().t problems had deal with.

everyone! i'm trying deal eclipse rcp 3.x application. i've read lot of articles dependency injection in rcp e4 applications. can use di in rcp 3.x apps? i found perfect link di in e4. idea how use in rcp 3.x app? first of all, i'm interested in own objects injection (btw, how add own object application context?). best regards in 3.x code can ieclipsecontext necessary use contextinjectionfactory using ieclipsecontext workbenchcontext = platformui.getworkbench().getservice(ieclipsecontext.class); to workbench context. in view or editor can current part context using: ieclipsecontext partcontext = getsite().getservice(ieclipsecontext.class);
