Auswahl eines Bildes aus der Kamera funktioniert, aber nicht aus dem Gallary [VIDEO DEMO]

Question

Ich habe einige Beispiele auf SO gefolgt, wie man ein Bild von Camera oder Gallary retrive. Der Kamerateil funktioniert, aber der Gallertenteil nicht. Der Code scheint für mich sehr diffus zu sein, also weiß ich nicht, worauf genau ich achten soll.

Ich habe auch die erforderlichen Berechtigungen in meinem Manifest. Hier

ist ein Video des Problems: https://www.youtube.com/watch?v=OOoY1y4W86w

Verwenden Sie den folgenden Code, um ein Bild aus der Galerie auszuwählen.

Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 
    intent.setType("image/*"); 
    //Here PICK_FROM_GALLERY is a requestCode 
    startActivityForResult(intent, PICK_FROM_GALLERY); 

In onActivityResult():

if (resultCode == Activity.RESULT_OK && requestCode == PICK_FROM_GALLERY) { 
     if (data.getData() != null) { 
      mImageUri = data.getData(); 
     } else { 
      //showing toast when unable to capture the image 
      Debug.toastValid(context, "Unable to upload Image Please Try again ..."); 
     } 
}
