  extensions = ['pdf'];

  },
};

const mediafilepicker = new Mediafilepicker();
mediafilepicker.on('getFiles', async res => {
  this.ngZone.run(() => {
    const results = res.object.get('results');
    console.log(results);
  });
});

mediafilepicker.on('error', res => {
  const msg = res.object.get('msg');
  this.logger.error('Upload error : ', msg);
  this.toggleSelector();
});

mediafilepicker.on('cancel', res => {
  console.log('cancel', res);
});

mediafilepicker.openFilePicker(options);`

Additional context Add any other context about the problem here. documentPickerDidPickDocumentsAtURLs is not called so thats why getFiles is not triggered, I try to resolve it and make a PR, but I can't make it work. PS: Thanks for this plugin !

got same issue on iOS, no file returns, actually it happens very randomly (not always).

is there any solution/workaround for this?

or is there a function where I can detect if the "file browser/directory" closed (so I can just put an error message whenever this issue happen)?

[kriefsacha]

Moved all the "on" to ngOnInit (i'm on nativescript-angular), and called the openFilePicker only on click of button and it fixed for me

[paul-castro]

yeah, I think seperating the openFilePicker method from other plugin's methods will do the trick

[erkanarslan]

I have this problem too. Also error and cancel callbacks are sometimes not called as well.

[kriefsacha]

Try to do as i saied @erkanarslan , put the "on's" functions and initialisation on the beginning and call the openFilePicker like on a button click or something

[erkanarslan]

Filepicker is used in many places in my app. Because of that I put it into a service. I cannot do that.

[kriefsacha]

So initialize it in the constructor of your service

[erkanarslan]

@kriefsacha I tried that and it works. Instead of creating a new filepicker instance each time, I created one instance and used it for all operations.
