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 (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>
