How can I give the FileOpenPicker a flag for android? (GrantPersistableUriPermission)

[jp-weber]

I want add for the Android FileOpenPicker the intent flag for the persistent access. Is there any way to do this without rebuilding the function? The current problem is that with the fileopenpicker, persistent access to the files is not possible, which is required for my app.

uno/src/Uno.UWP/Storage/Pickers/FileOpenPicker.Android.cs

Line 59 in 56d3ba9

intent.SetType("*/*");

Set

intent.AddFlags(Android.Content.ActivityFlags.GrantPersistableUriPermission);

and for the result =>

Android.App.Application.Context.ContentResolver.TakePersistableUriPermission(androidUri, Android.Content.ActivityFlags.GrantPersistableUriPermission);

There isn't any at this time, be it could be possible provide a way to access the intent before it is started.

Something like:

var disposable = FileOpenPickerHelper.RegisterOnBeforeStartActivity(picker, intent => intent.AddFlags(Android.Content.ActivityFlags.GrantPersistableUriPermission));

Which would set allow the user to set a callback directly into FileOpenPicker for android.

Oh that would be awesome 😊
