Witam,
Mam problem z przypisaniem obrazku z internetu do imageView. Po uruchomieniu programu nie wczytuje obrazka z sieci. Błąd, który wyskakuje to :
E/BitmapFactory: Unable to decode stream: java.io.FileNotFoundException: https:/i.ytimg.com/vi/heQ1ud0B9q4/default.jpg (No such file or directory)
W/ImageView: resolveUri failed on bad bitmap uri: https://i.ytimg.com/vi/heQ1ud0B9q4/default.jpg
