DocumentPicker.show() callback is no executing

Hi all, use this library in my project and the picker works as well, but the callback do nothings… This is my code:

DocumentPicker.show({
  filetype: [DocumentPickerUtil.pdf()],
}, (error, res) => {
  console.log('Fired!');
  if (error) return console.log(error);
  return console.log(res);
});

The document picker works, I choose a file and apparently works but the console don’t shows nothing.

I’m using React-Native 0.49.1, Android 5.1, Android Studio 3

Pd: I get this line in console: 11-27 14:06:48.306 13977-13977/com.android.documentsui D/Documents: onFinished() [content://com.android.externalstorage.documents/document/3CDD-ACC7%3AWhatsApp%2FMedia%2FWhatsApp%20Documents%2FTutorialPython2.pdf]'

Hi, I solve this just adding

public void onActivityResult(int requestCode, int resultCode, Intent data) {
  mReactInstanceManager.onActivityResult(this, requestCode, resultCode, data);
}

to my main java react native activity an works!

Why isn’t this documented? As an iOS developer implementing some native Android features in an hybrid RN app with very little Android experience, I feel like this could be useful there.
