I can't figure how send a file to shared in others apps, that I need to filter from a small list of it. I have read several tutorials and answers (like Share file to another app (whatsapp, telegram, gmail)) with no success:

override this.OnCreate (bundle) =



    base.OnCreate (bundle)

    this.SetContentView (Resources.Layout.Main)



    let button = this.FindViewById<Button>(Resources.Id.myButton)

    button.Click.Add (fun args -> 

        let fileName = Environment.GetFolderPath (Environment.SpecialFolder.MyDocuments)

        let fileName = Path.Combine([|fileName; "AboutAssets.txt"|]) |> Path.GetFullPath

        this.Launch(fileName)

    )



member this.Launch(fileName:string) =



    let context = Android.App.Application.Context

    let getUri file =

        Android.Support.V4.Content.FileProvider.GetUriForFile(context, Android.App.Application.Context.PackageName + ".provider", file)



    let file = new Java.IO.File(fileName)

    let path = getUri file

    let extension = Android.Webkit.MimeTypeMap.GetFileExtensionFromUrl(path.ToString())

    let fileMime = Android.Webkit.MimeTypeMap.Singleton.GetMimeTypeFromExtension(extension)



    let intent = new Android.Content.Intent(Android.Content.Intent.ActionSend)

    intent.SetFlags(Android.Content.ActivityFlags.ClearTop) |>  ignore

    intent.SetFlags(Android.Content.ActivityFlags.NewTask) |>  ignore

    intent.SetType("*/*") |> ignore



    let apps = [| "excel"; "mail"; "gmail"; "whatsapp"; "dropbox"; "drive" |]



    let findApps() =

        let packageManager = context.PackageManager

        let resInfo = packageManager.QueryIntentActivities(intent, Android.Content.PM.PackageInfoFlags.Activities)



        let targetedShareIntents = new ResizeArray<IParcelable>()



        let pkgs = seq {

            for info in resInfo do

                let namePkg = info.ActivityInfo.PackageName.ToLower()

                let nameApp = info.ActivityInfo.Name.ToLower()



                let label = info.LoadLabel(packageManager)

                let icon = info.Icon;





                for app in apps do

                    if nameApp.Contains(app) || namePkg.Contains(app) then

                        yield (app, info)

        }



        for (app, info) in pkgs |> Seq.distinct do

            let label = info.LoadLabel(packageManager)

            let icon = info.Icon;



            let targetedShare = new Android.Content.Intent(Android.Content.Intent.ActionSend)



            if app.Contains("email") then

                targetedShare.SetType("message/rfc822") |> ignore //not work

            else

                targetedShare.SetType(fileMime) |> ignore

            targetedShare.SetType(fileMime) |>  ignore



            targetedShare.PutExtra(Android.Content.Intent.ExtraText, "My body of post/email") |>  ignore

            targetedShare.AddFlags(Android.Content.ActivityFlags.GrantReadUriPermission) |>  ignore



            targetedShare.PutExtra(Android.Content.Intent.ExtraStream, path) |> ignore

            targetedShare.SetData(path)|>  ignore

            targetedShare.SetFlags(Android.Content.ActivityFlags.ClearTop) |>  ignore

            targetedShare.SetFlags(Android.Content.ActivityFlags.NewTask) |>  ignore



            //targetedShare.SetData(uri) |> ignore

            let label = new Android.Content.PM.LabeledIntent(targetedShare, info.ActivityInfo.PackageName, label, icon)

            targetedShareIntents.Add(label) |>  ignore



        targetedShareIntents



    let apps = findApps()

    printf "%A" apps

Android.Content.Intent(Android.Content.Intent.ExtraInitialIntents, apps)

    let chooser = Android.Content.Intent.CreateChooser(intent, "Choose App")

    chooser.PutExtra(Android.Content.Intent.ExtraInitialIntents, apps.ToArray()) |> ignore



    chooser.SetFlags(Android.Content.ActivityFlags.ClearTop)|> ignore

    chooser.SetFlags(Android.Content.ActivityFlags.NewTask) |> ignore           



    context.StartActivity(chooser)

When I open gmail, the file not show, and not error is displayed. When open Google Drive it say "Upload was not sucessfull, request contained no data"

P.D: The config:

<provider android:name="android.support.v4.content.FileProvider" android:authorities="com.companyname.basura.provider" android:exported="false" android:grantUriPermissions="true">

 <meta-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/provider_paths" />

</provider>

And provider_paths:

<?xml version="1.0" encoding="UTF-8" ?>

<paths xmlns:android="http://schemas.android.com/apk/res/android">

  <files-path name="files" path="."/>

</paths>
